Welcome

Thank you for purchasing the 788T/788T-SSD. The ultra-compact 788T records and plays back up to 12 tracks of audio to and from its internal drive, CompactFlash, or external drives, making ﬁ eld recording simple and fast. It writes and reads uncompressed PCM audio at 16 or 24 bits with sampling rates between 32 kHz and 192 kHz. The time code implementation makes the 788T ready for any recording job—from over-the-shoulder to cart-based production.

The 788T implements a no-compromise audio path that includes Sound Devices’ high-performance microphone preampliﬁ ers. Designed speciﬁ cally for high bandwidth, high bit rate digital recording, these preamps set a new standard for frequency response linearity, low distortion performance, and low noise.

With documentary and ENG mixing engineers in mind, the 788T is very small, while still being feature-rich. No other recorder on the market matches its size and feature set. In addition, its learning curve is quite short—powerful does not mean complicated.

Inputs and Outputs

Input Setup and Control

The 788T has eight inputs and twelve record tracks. Inputs can be analog or digital sources. Analog inputs 1 through 4 are on 3-pin XLR connectors; inputs 5 through 8 are on 3-pin TA3 connectors. Digital AES3 inputs 1-8 use the DE-15 (D-Sub) connector.

Analog and digital inputs can be used simultaneously, for a total of eight.

Input Trim and Input Faders

The Front Panel Input Gain Controls can be switched to the Off position to disable and power down the input and to ultimately extend battery life. Disable inactive inputs by turning the Input Gain Control to the full counter-clockwise (Off) position. The Input Gain Controls must be on to route an input to a track and/or access the Input Settings Window.

The gain of an input is adjusted by two controls, its Input Trim and its Input Fader. This two-stage control is identical the to topology of mixing consoles and provides a great deal of ﬂ exibility when inputs are assigned to tracks. Input Trim is often thought of as a coarse gain control and Input Fader is thought of as the ﬁ ne gain control.

From the factory, the front panel Input Gain Controls adjust trim levels. When an input is sent to a track, the input is sent at the level controlled by the Input Trim. In this factory default mode, the Input Fader control is set at unity, cannot be controlled, and has no effect on levels.

The Setup Menu option INPUT: FRONT PANEL CONTROLS provides three options, Trim Control, Fader Control, or Input Enables Only. This menu is not available when the CL-9 is attached. Selecting Fader Control changes the eight front panel Input Gain Controls to adjust the fader level on an input. Trim levels are now set using the Rotary Switch from within the respective input’s Input Settings Window. Pressing in on the Rotary Switch will toggle between Trim control and High-Pass Filter control. When Input Enables Only is selected, the Front Panel Controls turn the inputs on and off only and the Trim Level is controlled within the Input Settings Window.

When Input: Front Panel Controls is set to anything other than Trim Controls, panning linked inputs is disabled.

The fader range is adjustable in the Setup Menu option INPUT: FADER RANGE between Wide, Fade Only, and Narrow. A Wide range allows the user to attenuate the fader from negative inﬁ nity (off) to +15 dB. Fade Only allows the user to attenuate the fader level from negative inﬁ nity (off) to 0 dB. A narrow range allows the user to attenuate the fader level from -15 to +15 dB. Fader levels are relative to the trim level of the selected input. Fader range applies to all available faders including, Front Panel Gain Controls (if set as Fader controls in the Setup Menu option Input: Front Panel Controls), the CL-2 fader, the CL-8, and the CL-9 faders.

The CL-8 and CL-9 faders can be calibrated in the Setup Menu option FADER CAL. This allows the Sound Mixer to set the 0 dB (unity gain) position of the fader. To calibrate the faders of the CL-8 or CL-9, set all fader levels to the desired 0 dB position. Enter the Setup Menu option FADER CAL and press the check mark.

v. 3.02 Features and specifications are subject to change. Visit www.sounddevices.com for the latest documentation.

788T/788T-SSD User Guide and Technical Information

When the CL-9 is attached to the 788T, the trim and fader levels are adjusted only from the CL-9. The 788T Front Panel Gain Controls simply activating/deactivating inputs.

When the CL-8 is attached to the 788T and the Setup Menu option INPUT: FRONT PANEL CONTROLS is set to Trim Controls or Fader Controls, the behavior of the front panel Input Gain Control adjusts trim levels and the CL-8 rotary potentiometer controls the Input Fader level. When Setup Menu option INPUT: FRONT PANEL CONTROLS is set to Input Enables Only, the behavior of the front panel Input Gain Control simply activates/deactivates the input, trim levels are adjusted in the Input Settings Window using the Rotary Encoder, and the CL-8 rotary potentiometer controls the Input Fader level. When the CL-8 is attached, the Fader Controls option has no effect. The front panel controls continue to act as trims and the CL-8 faders act as input fader controls.

When the CL-2 is attached and assigned to an input, the input’s fader level will be controlled by the CL-2 only.

Input Settings Window

From the Input Settings Window, view and/or change the following settings:

• Input Type

• Phantom Power

• High-Pass Filter

• Input Gain (Trim and Fader)

• Input Limiter

• Input Polarity

• Input Mute

• Input Routing

• Mix Assist

To enter the Input Settings Window, press the desired input’s Front Panel Input Selector Switch. The Input Settings Window will latch on, this allows for one handed operation of the 788T. If momentary action is desired, press and hold the Input Selector Switch for one second or more. To exit the Input Settings Window press the selected Input Selector Switch again or select another Input.

While in the Input Settings Window the selected input is displayed in the center of the screen. The selected input will be soloed in the headphone monitor, although this can be disabled in the Setup Menu option INPUT : P FL FUNCTION.

If the Input Selector/Solo Switch is held for 5 or more seconds “Hold” will appear on the screen and the soloed input will remain in the headphone monitor until either another headphone monitor mode has been selected with the Rotary Switch or with the Input Selector/Solo Switch. Once the Input Selector Switch is pressed again, the 788T will return to the previously displayed screen.

If the selected input is stereo linked, both of the inputs will be soloed in the headphone monitor.

Line XLR 1-4, TA3 5-8 Off (-infinity) -25 dB to 50 dB

Digital AES3 1-8 (D-Sub 15) Off (-infinity) -25 dB to 76 dB.

Phantom Power

Phantom power (48 volts) can be activated individually, for each analog input on. Phantom power can be used for both mic- and line-level inputs. Enable or disable Phantom Power in the Input Settings Window using the Tone key to select 48V (phantom power for mic level only), 48VL (phantom power for mic- and line-level), or Off.

Using line-level inputs with microphones is useful in high SPL environments such as recording ﬁ rearms or loud concerts. Make certain to disable phantom power on inputs with attachedc line-level output devices that might be susceptible to damage from DC.

Inputs and Outputs3

High-Pass Filters

High-pass ﬁ lters on analog and digital inputs reduce sensitivity to low frequency signals. Pressing the Rotary Switch will engage or disengage the High-Pass Filter. Turn the Rotary Switch to select the cut off frequency in 10 Hz steps from 40 Hz to 320 Hz.

If the Setup Menu option INPUT: FRONT PANEL CONTROLS is set to Fader Controls, pressing the Rotary Switch will toggle between Trim and High-Pass Filter control.

Filter slopes of 6 dB and 12 dB per octave are selectable in the Setup Menu and will apply to all inputs where the high-pass ﬁ lter have been engaged.

Input Gain

The gain display will toggle between trim and fader levels (if applicable). If the Setup Menu option INPUT: FRONT PANEL CONTROLS is set to Fader Controls or Input Enables Only, pressing the Rotary Switch will toggle between Trim and High-Pass Filter control. When Trim is selected, turn the Rotary Switch to adjust the trim level.

Input Limiters

Analog inputs incorporate an advanced, analog/DSP-controlled hybrid limiter to prevent input overload. In normal operation and with proper gain settings, the limiters should rarely engage. When activated, these limiters prevent unusually high input signal levels from clipping the analog input stage of the preamp.

The 788T is equipped with 16 Input Limiters, a pre-fade and a post-fade limiter for each input. Limiting is applied only at the stage of the signal path where the level exceeds the set Limiter Threshold. If the threshold is exceeded at both pre- and post-fade stages, each limiter will act independently of one another.

v. 3.02 Features and specifications are subject to change. Visit www.sounddevices.com for the latest documentation.

788T/788T-SSD User Guide and Technical Information

The Input Activity LEDs illuminate yellow when an input is being limited at either stage. When a fader accessory is connected, the 788T will indicate pre-fade limiting and the fader accessory will indicate post-fade limiting. The Input Limiters are active for both mic- and line-level inputs.

Enable or disable the Input Limiters using the soft Lim (HDD) key while in the Input Settings Window. This enables/disables both the pre- and post-fade limiters. The 788T offers several adjustments for its peak limiter to tailor the sound to the user’s desire: Threshold; Knee; Ratio; and Recovery.

The Limiter Threshold adjusts the maximum peak level at which the limiter will engage. Sounds louder than this threshold are attenuated. This threshold is adjustable in the Setup Menu option INPUT : L IMI TER THRESHOLD from -12 to -2 dBFS in .1 dBFS increments.

The Limiter Recovery adjusts how slowly the limiter brings its gain back up after a peak is limited. A shorter recovery follows the envelope of speech better than a longer recovery, but at the expense of low-frequency distortion. Recovery time is adjustable in the Setup Menu option INPUT: LIMITER RECOVERY from 50 msec to 2000 msec in 10 msec increments.

Setup Menu option INPUT : L IMI TER KNEE allows the user to control the ratio at which the signal is limited and whether the limiter has a Hard- or Soft-Knee. The limiter ratio is either inﬁ nite: 1 or 20:1. The hard knee setting leaves all program material below the threshold completely unaffected and attenuates only those peaks above the threshold. The soft knee setting attenuates the program material slightly before the threshold (about 6 dB) for a more gradual tape-like sound.

Inputs can have their limiters linked or grouped according to the Input Linking settings. This is ideal for working with stereo or surround sources. See Input Linking.

Input Limiters are disabled when set to record at high sampling rates (48048 +).

Input Polarity

Input Polarity inversion (sometimes referred as phase reverse) can be applied to both analog or digital inputs. This can be used to rectify incorrectly wired balanced cables, to prevent signal cancellation when a source is dual-miked from opposite directions, or reverse left/right with MS microphones. Select between Normal and Inverse polarities using the LCD Backlight key. When the Input Polarity symbol is highlighted, the polarity is inversed.

Input Mute

To mute an input, press the soft Mute (Fast Forward) key. When an input is muted, the Mute display will ﬂ ash and the respective Input Activity Ring LED illuminates solid red. Muting an input effectively turns the Input Gain Pot to negative inﬁ nity without having to touch the Input Gain Pot. Muting an Input does not change the Input to Track Routing. Muted Inputs assigned to tracks that are record enabled will record silence. This is useful when an input is not needed temporarily but the user wishes to maintain all settings, levels, and track counts.

Input to Track Routing

The Input to Track Routing allows the user to quickly view and edit the input-to-track routing for the selected input. The highlighted selections indicate the tracks that the input is currently routed to. In order to record, tracks must be armed in the Track Setup Menu. For more details view the Input to Track

Routing Section.

Inputs and Outputs3

788T/788T-SSD User Guide and Technical Information

Analog Inputs

Analog inputs 1-4 on XLR connectors and analog inputs 5-8 on TA3 connectors, are the primary connections into the recorder. These inputs accept balanced or unbalanced mic- or line-level inputs. Gain is controlled by the front panel Input Gain Pots.

Input Linking (Stereo or MS Decoding)

Inputs 1-8 can be grouped or linked together to ensure that gain is applied evenly across all linked inputs. Linked inputs can also be muted and un-routed from tracks by using a single Input Trim Pot. Input settings such as Input type, Limiter, Phantom Power, and High-Pass Filters are also linked and will be applied across all linked inputs.

Neighboring inputs can be linked as stereo pairs in the following sequences: 1-2, 3-4, 5-6, and 7-8. When linked, the odd Input’s trim controls the signal level of linked inputs, and the even Input’s trim controls the left-to-right balance of the stereo pair.

When linked, the Input Selector Switch will solo the linked pair in the headphone monitor. For example if Input 1 and Input 2 are linked as a stereo pair, pushing the Input Solo Switch will change the headphone monitor to 1,2 (Input 1 on the left-side and Input 2 on the right-side of the headphone monitor).

Inputs and Outputs3

When a CL-8 is attached or the Setup Menu option INPUT: FRONT PANEL CONTROLS is set to Fader Controls, the odd Fader will control the post fade signal level of the linked pair and the even fader will be disabled.

MS Linking

Mid-side (MS) matrixing is a method for processing audio signal from a cardioid microphone and a bidirectional microphone into a stereo signal. The cardioid microphone is the “mid” signal and connects to input 1, and the bidirectional microphone is the “side” signal and connects to input 2. The cardioid microphone is pointed at the sound source, and the bidirectional microphone is oriented sideways (positioned with its capsule as near as possible to the cardioid microphone’s capsule). the following diagram shows the relative polar patterns of microphones in an M/S conﬁ guration.

Mid Signal

Side Signal

When set to link as an MS pair, the inputs are decoded as MS stereo, where the gain and balance for the pair work the same as stereo linking above. The odd input is for Mid signal and the even input is for Side signal.

By default MS decoded signal from MS linked inputs will go to all tracks, pre- and post-fade. Changing Setup Menu option Input: MS to Pre-Fade ISO to Off, will cause signal from MS linked inputs that is routed to any ISO tracks (A through H) pre-fade, to be discrete mid and side signal (bypassing the MS decoder). Signal from MS linked inputs routed anywhere else will be MS decoded (including post-fade routings to ISO tracks).

788T/788T-SSD User Guide and Technical Information

Digital Inputs

The 788T accepts AES3 (AES/EBU) balanced and AESid unbalanced digital signals in professional or consumer format via its DE-15 connector. The 788T will auto detect the type of digital signal and adjust accordingly. Digital input gain is controlled via the front panel potentiometers.

To use a digital input, the Input Type switch located in an input’s Input Settings Window must be set to Digital. Although a digital input signal contains a pair of inputs, the 788T is able to select just one of the pair as an input, so for example, it is possible to select line or mic for Input 1 and digital for Input 2.

When recording from a digital input, it is important to sync the 788T’s sample clock from a source that is synchronous with the digital input signal otherwise audio quality will be degraded. See Syn-

chr

onization. The simplest way to achieve this is to set the 788T to derive its sample clock from the

clock embedded within a digital signal. Go to the REC: S YN C REFERENC E Setup Menu and set the sync source to the applicable digital input pair.

The LCD will display ‘D’ when locked to the selected digital input. If the Input Activity ring LEDs are ﬂ ashing, then a digital input is selected but no valid digital clock is being received.

AES42 Digital Microphones

The 788T is compatible with digital microphones conforming to the AES42 speciﬁ cation, such as the Schoeps CMD-2U. By setting DIGITAL INPUT: AES42 POWER to Enabled, the 788T supplies +10V of “digital phantom power” to each of the digital inputs. The gain of the microphone can be adjusted with the 788T’s front panel gain control just like a normal analog microphone. The gain adjustment is controlled in the 788T digital domain.

Never apply digital phantom to unbalanced digital inputs, as this can result in damage to the hardware.

The 788T can lock its sample clock to a single AES42 digital microphone signal. This is set from the Setup Menu option REC: S YN C REFE RE NCE to the corresponding digital inputs. When the 788T is set to use its internal clock any connected incoming AES3 or AES42 signal is sample rate converted.

Things to consider when using AES42:

• The 788T supports four AES42 pairs.

• The 788T supports AES42 Mode 1 operation, Mode 2 operation is not supported. In other words, the 788T supports digital audio transfer via AES42. However, it does not support the AES42 protocol for remote control, microphone identiﬁ cation, or status ﬂ ag indicators. Mode 2 microphones will automatically operate in Mode 1 when connected to the 788T.

• When using multiple AES42 microphones set the REC: SYN C REFERE N C E to Internal. This will ensure a synchronous operation between the 788T and digital microphones.

Input Delay

A digital delay is selectable on each input of the 788T. Delay time per input is selectable in tenths of a millisecond (0.1 msec) steps up to 30 msec. Each input has its own designated Input Delay Setup Menu. If an input is turned Off, its Input Delay Setup Menu is crossed out. Delay is not set until the Rotary Switch is pressed or the Check Mark (Tone) soft key is selected.

Input delay is limited to 15 milliseconds with sampling rates above 88.2 kHz and 7.5 seconds with sampling rates above 96.096 kHz.

Inputs and Outputs3

Input delay can be useful for time aligning input signals from differing sources. For example, digital wireless mics that have a processing delay in their outputs. In addition, all digital conversion stages have delay.

788T/788T-SSD User Guide and Technical Information

Deactivate Inputs

Deactivate inputs by turning the Input Gain Pot to the full counter-clockwise (Off) position, the pot should click off. A deactivated input is muted and un-routed from any of its designated tracks. Deactivated inputs disables associated circuitry and ultimately extends battery life. Input Activity LEDs for each respective input will remain off when deactivated. When an input is clicked to Off the Input Selector/Solo Switch for the respective input will also be deactivated.

Tip: Clicking on and off Input Gain Pots can be used to arm and disarm tracks. In order for a track to be

recorded, it must have at least one active input routed to it. Because of this rule, deactivating an input will effectively disarm the associated track, given than no other active inputs routed to it. If it is desired to record an empty or silent track without effecting audio levels the Input can be muted in the Input Settings Window.

Outputs – Analog and Digital

The 788T has six analog and six digital outputs. Each of these outputs is assigned an audio source independently, enabling the 788T to feed multiple outputs with unique program. Although there are only six outputs, it is possible to output all eight inputs individually by using the Headphone Out-

Inputs and Outputs3

put together with the six outputs.

Output Routing

The audio sources for each output bus are set in the Setup Menu option OUTPUT: ROUTING. Rotat- ing the Rotary Switch will move the highlight box amongst the available sources. Pushing the Rotary Switch will toggle the routing status of the highlighted item. The Menu and HDD buttons will scroll the view up and down to access other outputs.

The chart below shows the audio sources available for each of the Output Busses. Each row in this table represents a group of sources that is mutually exclusive from the sources represented in other rows.

Outputs can be set to receive Slate Mic (CL-8 or CL-9) or COM1 or COM2 (CL-9 only) announcements. See the CL-8 Slate Mic or CL-9 Communications sections for details.

Output Types

Audio signals routed to an output are sent to both the analog and digital outputs simultaneously. For example, the audio source signal selected for Output 1 is sent to both analog output 1 and digital output (AES) 1.

The CL-9 has an Output Mode that allows the user to solo the output in the headphone monitor and make quick adjustments to the Output level, including Mute. See CL-9 Modes for details.

Analog Balanced Line Outputs 1-4

The analog line outputs are active-balanced line-level signals on Switchcraft-type TA3M locking connectors. The output level is a nominally 0 dBu at 20 dBFS. The line-level output can be adjusted in the Setup Menu from -40 to 0 dB in 1 dB increments.

Analog Unbalanced Output 5-6

This is a two-channel output on a TRS 3.5 mm connector with nominal level of -10 dBV. This level can be adjusted in the Setup Menu from -40 to 0 dB in 1 dB increments.

Balanced Digital AES Outputs 1-6

Balanced AES outputs 1-4 are on TA3 connectors on the right side panel. Balanced AES outputs 5-6 are on the DE-15 connector on the rear panel. See Connector Pin Assignments. These outputs are compatible with most AES3 and S/PDIF inputs.

The format for the AES3 output is selectable between professional AES and consumer SPDIF. In either case the SCMS bit is not set. The output level of the digital outputs is not adjustable.

Output Delay

Output audio signal can be delayed on Outputs 1 and 2 from the Setup Menu options OUTPUT 1/2: DELAY. Delay is adjusted from 0 to 10 frames in increments of 0.1 frames. The amount of delay in mS is dependent on the selected frame rate in Setup Menu Option TIMECODE: FRAME RATE.

Output Delay is a processor-intensive feature. Sound Devices recommends using fast media, avoiding recording to more than two media, and to refrain from using MixAssist when any amount of Output Delay is applied.

Input to Track Routing

The 788T offers a great deal of routing ﬂ exibility. Any input can be routed to any track. With this powerful routing, iso tracks and sub-mixes can be recorded simultaneously.

Input to track routing is managed from any of four screens/controls:

• the Input Settings Window,

• the Setup Menu

• the Track Setup Window, or

• from an attached CL-8 (only tracks L, R, X1, and X2 can be routed from the CL-8).

• from an attached CL-9

• from the CL-WiFi application

Tracks are destinations for inputs, they can be routed to outputs and/or selected for recording. See

Track Arming. The following diagram displays the available input to track routing options, the check

marks and asterisks indicate factory default settings.

Pre-Fade vs. Post Fade

Inputs can be assigned to tracks either pre- or post-fade. Pre-fade tracks are fed the respective input’s audio signal immediately following the Trim level stage of the signal path. Fader adjustments have no effect on pre-fade Tracks.

Post-fade tracks are fed the respective input’s audio signal immediately following the Fader level stage of the signal path. Fader levels range is adjustable and is relative to the Trim level. Fader adjustments do affect the audio signal sent to post-fade tracks. Pre- and post-fade assignments are applied to all inputs routed to that track.

tion for more details.

Mix Assist™

Mix Assist™ is a powerful feature of the 788T which can automatically attenuate the level of any microphone which is not active, reducing the background noise level in the mix. This function is commonly referred to as “automix”. The 788T’s MixAssist™ feature automixes post-fade signals to the L and R tracks. Pre-fade signals are not affected by Mix Assist.

Inputs that are automixed will be “open” (unattenuated) when a person talks into the input’s microphone and “closed” (attenuated) when the person stops talking. Microphone channels open within 1 mS to ensure that no syllables are lost, and then will gate off smoothly over 500mS. This gating action is smooth and imperceptible when switching between microphones. Mix Assist will allow several microphones to be open simultaneously if there are several talkers - Mix Assist does not limit the number of open microphones.

Mix Assist is more sophisticated than a simple gate, and uses four different principles to automix input signals.

Noise Adaptive Threshold

An input with Mix Assist enabled will be smoothly attenuated by 20 dB when its microphone is below the adaptive threshold. The threshold is not a static level (as with the limiter or simple gate) but a level which changes dynamically based on the average level of the input. This prevents common background noise (fans, crowd murmur, etc) from causing the input to open, while allowing normal sounds to open the mic.

Number of Open Microphone Attenuation

As the number of open inputs increases, the level of each input as it is routed to the track will decrease by 3 dB per doubling of open mics. This ensures that the overall level of the track is consistent regardless of the amount of open inputs routed to it.

v. 3.02 Features and specifications are subject to change. Visit www.sounddevices.com for the latest documentation.

788T/788T-SSD User Guide and Technical Information

Last Mic Lock-On

When talking stops, the last input to be active will remain open. This maintains a consistent level of natural sound and avoids a dramatic transition to silence on the track, even when no inputs are in use.

One Mic Per Sound Source

Often a sound source (i.e. someone speaking) is captured by more than one microphone. Mix Assist actively compares signals from all inputs and when it senses the same audio on multiple inputs, it will only open the input in which that speciﬁ c program audio is loudest. Note that this does not prevent another input from opening when unique program audio is sensed at that input.

Using Mix Assist

Mix Assist is enabled when the Setup Menu option MIXASS IST: MODE is set to ON (LR TRACKS ONLY ) or ON (ALL TRACKS FOLLOW LR ). Each input to be automixed will then

have “AUTO” highlighted in the Input Settings window. Any input can then be switched to manual operation, forcing that input to stay on regardless of level. Press the Rewind key in the Input Settings Window to activate or deactivate Mix Assist for that input.

When ON (LR TRACKS ONLY ) is selected, Mix Assist attenuation is applied to the tracks L and R only. This allows the user to simultaneously create both a mix-assisted mix on tracks L and R and a manual mix on any other track set to post-fade. When ON (ALL TRACKS FOLLOW LR) is selected, Mix Assist enabled inputs routed to post-fade tracks will be attenuated by Mix Assist.

The input activity LED ring will light bright green to indicate an automixed input that is currently open. The input activity LED for closed inputs will be off. This input activity LED ring behavior overrides the metering behavior of the input activity LED ring.

Inputs that are routed post-fader to track L or R and do not have automix activated will not be automixed but will still be analyzed by Mix Assist for the purposes of Last Mic Lock-On, One Mic Per Sound Source, and Number of Open Mics Attenuation. The input activity LED ring for these inputs will light dim green and show metering activity.

Mix Assist is a processor-intensive feature. Mix Assist is disabled when the sampling rate is above

48.048 kHz. Recording mono ﬁ les is not recommended when using Mix Assist. Output Delay is not recommended when using Mix Assist. When a CF card is in use, UDMA is recommended.

Recording and Playback5

Recording and Playback

The 788T is a record-priority device. With very few exceptions (disk formatting, and ﬁ le transfers), pressing the REC key at any point during operation will initiate recording.

The largest, most easily accessed control on the 788T is its REC key. The 788T will immediately enter Record mode when the REC key is pressed. If the storage media selected is not ready to begin recording a new ﬁ le, the REC key will ﬂ ash red and the LCD will display REC ORD PE N DING until the recording has begun.

When recording, the REC key, adjacent red LED, and the LCD backlight will all illuminate red to indicate that the unit is in record mode. The behavior of the LCD backlight can be adjusted with Setup Menu option LCD: BACKLIGH T MODE.

Recording integrity is further enhanced through a process of periodic, automatic ﬁ le directory and header updates written to disk during recording. This ensures ﬁ le integrity in the unlikely event of a total loss of power.

If no tracks are armed to record, the 788T will not enter Record Mode. Make certain that at least one record track is armed for recording.

While recording, the POWER, FAST FORWARD, REWIND, PLAY and TONE keys are disabled. See

Panel Lock to engage Panel Lock during recording. Stop recording by pressing and holding the STOP

key for at least 150 milliseconds. items that affect recording are lined out in the menu list.

Although you can enter the Setup Menu during recording, menu

During recording, subsequent presses of the REC key can perform one of three Setup-Menu-selected actions:

• no action,

• new cue - cue markers are set within the ﬁ le being written,

• new ﬁ le - a new ﬁ le is started with each press of the REC key, the take counter increases by one.

Pre-Record Buffer

To prevent missing record cues or up-cutting takes, the 788T has a pre-record (or pre-roll) buffer. When active, pre-record begins recording at a set number of seconds preceding the REC key being pressed. When recording higher sampling rates (48048 +) pre-roll is limited to ﬁ ve seconds and below.

Record buffering is disabled when the time code mode is set to Record Run. In External Time Code Auto Record and External Time Code Continuous Auto Record modes, the Pre-Record Buffer is only active from the time the 788T receives a valid time code signal. This allows the 788T to capture audio before the set Time Code Hold Off value is reached. See Time Code Hold Off for additional information. This prevents possible overlapping time code numbers between adjacent ﬁ les.

Media Select

The 788T can record up to 12 tracks to all three available media (internal drive, CompactFlash, and external hard drives) simultaneously at sampling rates of 48048 and below. Higher Sampling rates are limited to eight tracks to two media only. When recording higher track counts and higher sam-

Media must be selected in the Setup Menu option REC : MED IA S ELEC T in order for material to be written to it. Tracks can be individually routed to CompactFlash, Internal drive, and External media.

See Track-to-Media Routing.

Failure During Recording

In the event of a storage media failure, the speciﬁ c error will be indicated on the LCD and warning bells in the headphone monitor. Possible causes of media failure include, a hard drive in severe motion which results in recording errors, a CompactFlash card ﬁ lling up while recording, or an external DVD-RAM that can’t keep up with the chosen data rate, track count, or ﬁ le type. If more than one drive is selected for recording, the remaining drives will continue recording without failure. If a media continues to be displayed as slow after the warning prompt has been cleared, press the Stop key to clear the Slow status.

Record Timer

The 788T is equipped with a record start and stop timer. This allows a user to record a take at a speciﬁ c time from an unattended recorder. Set the start time in the Setup Menu option REC : TIMER START then set the record stop time in the Setup Menu option REC: TIMER STOP. The 788T will boot up and start recording when the timer start time elapses.

Track Arming

The 788T only records tracks that are armed. Armed tracks are tracks that are both record enabled and have active inputs routed to them. Track Enabling is controlled in the Track Setup Menu. To enable a track for recording perform the following steps.

1. Enter the Track Setup Menu by pressing the INPUT key.

2. Navigate through the Tracks using the Rotary Switch. The Track with the box around it is the

selected track. This is Track L in the above image.

3. A solid * (asterisks) in front of a given track indicates that the track is armed. Flashing * (as-

terisks) indicate that the track is enabled for recording but an active input is not routed to it, and the track will not be recorded. Enable/Disable select tracks by pressing in on the Rotary Switch. The above image indicates that Tracks L, R, A, B, C, D, E, F, G, and H are enabled for recording. Tracks X1 and X2 may have inputs routed to them, but are not enabled and will not be recorded.

Track-to-Media Routing

From the Track-to-Media View, tracks are individually assigned to CompactFlash, Internal Drive, or External media. This is extremely useful for those recording to a deliverable media, but only select tracks need to be delivered. For Example, the speciﬁ c application may require ten-track recordings, two-track stereo mix and eight isolated tracks. Instead of recording ten tracks to all three media, the user can select which tracks are written to each media. The user may opt to record all ten tracks to internal drive, eight isolated tracks to CompactFlash, and the two-track stereo mix to DVD-RAM.

The media status on the Main Display toggles between Remaining Time and Track Count when the given media is set to receive less than the full amount of armed tracks.

By default, all tracks are assigned to all available media. Tracks will only be written to a given media if the media is selected in the Setup Menu option REC : MED IA S ELEC T, regardless of it’s Track-to- Media routing status. See Media Select.

Track Limiters

Track Limiters prevent multiple summed inputs from overloading the track prior to being recorded. The Left, Right, X1, and X2 tracks are all equipped with their own track limiter. Track Limiter and the Input Limiters share the same characteristics as deﬁ ned in the Setup Menu.

Track Limiters are turned on by pressing the soft LIM (LCD Backlight) key in the Master Gain Levels View. Limiters settings are applied to both tracks in the pair. Tracks are paired as Left, Right and X1, X2.

Recording and Playback5

The Track Limiters can either be linked as a stereo pair (LINKED) or can work as two independent limiters (ON). When linked, the limiters will apply the same gain reduction equally to both tracks of the pair. LINKED is recommended when recording stereo program, so that level changes are identical on both tracks. ON is recommended when using the tracks of the pair as two separate buses.

Track Limiter activity is displayed in the Master Gain Levels Window. Track Limiter Indicators will appear when the Track Limiters are engaged. When Limiters are LINKED the indicators will be connected with a line. The Indicators are solid when the limiter is active. In the image below, the Left and Right Track Limiters are LINKED and actively limiting. The Aux Track Limiters are ON and only the X1 Track Limiter is actively limiting.

Master Gain Levels Using the CL-9

The CL-9 has dedicated physical master gain controls for the Left, Right, Aux 1, and Aux 2 Tracks. When the CL-9 is attached the Master Level Gains can only be adjusted using these level controls. Master Track Linking is still performed on the 788T in the Master Gain Levels Window. See CL-9

Sampling Rate and Bit Depth

The 788T generates uncompressed PCM audio WAV ﬁ les in the Broadcast Wave File format at the user-selected sampling rate and bit depth. The 788T LCD displays the remaining available recording time based on the sampling rate, bit depth, number of assigned tracks, and the selected storage media’s available capacity. See Apendix A - Record Time Calculation.

v. 3.02 Features and specifications are subject to change. Visit www.sounddevices.com for the latest documentation.

788T/788T-SSD User Guide and Technical Information

Sampling Rate

When a sampling rate is selected for recording, all tracks are recorded at the selected sampling rate. Sampling rates are selected among common rates from 32 kHz to 192 kHz. Additionally, nonstandard sampling rates can be applied when the 788T is word clocked from an external source (clock sources between 32 kHz and 192 kHz). When recording off-speed sampling rates, ﬁ les will be stamped with the rate closest to the internally generated frequency.

Sampling Frequency and Audio Bandwidth

The sampling frequency is expressed in samples per second (hertz) and deﬁ nes the number of times in a second that the analog audio signal has been measured. Sampling frequency determines the audio bandwidth, or frequency response, that can be represented by the digital signal. A quick estimate of the maximum bandwidth capable of being represented at a given sampling rate is maximum analog frequency = sampling frequency/2. Higher sampling frequencies allow for wider audio bandwidth.

The 788T generates the following sampling rates:

• 32 kHz

• 44.1 kHz

• 47.952 kHz

• 47.952 kHz “F Mode”

• 48 kHz

See Time Code for more information about F Mode sample rates.

• 48.048 kHz

• 48.048 kHz “F Mode”

• 88.2 kHz

• 96 kHz

• 96.096 kHz

• 96.096 kHz “F Mode”

• 176.4 kHz

• 192 kHz

Considerations When Recording With High Sample Rates

Increasing the sample rate above 48.048 kHz requires certain settings to be adjusted and imposes certain limits to some features. Increasing the sample rate above 96.096 kHz furthers these requirements. It is recommended to save settings for work ﬂ ows with a high sample rate, so they can be easily recalled.

Bit Depth

The 788T records at bit depths of either 16 or 24 bits. 24-bit recording provides greater dynamic range and addition headroom for signal peaks relative to 16-bit recordings. 24-bit recording (versus 16-bit) is a signiﬁ cant beneﬁ t for ﬁ eld production audio tracks.

Bit Depth and Dynamic Range

Bit depth deﬁ nes the digital “word length” used to represent a given sample. Bit depth correlates to the maximum dynamic range that can be represented by the digital signal. Larger bit depths accommodate more dynamic range. A quick estimate of the maximum dynamic range capable of being represented by a given word length is dynamic range ~= no. of bits x 6 dB. Bit depth is an exponen-

788T/788T-SSD User Guide and Technical Information

tial measure (exponent of 2), so as bit depth increases, the amount of data it represents increases exponentially. The majority of ﬁ eld recording is done with 16-bit audio, therefore, each sample is represented by a digital word of 2^16 (65,536) possible values. 24-bit audio has a word length of 2^24 (16.7 million) possible values per sample.

The 788T has 24-bit analog-to-digital converters. To obtain 16-bit recording the 788T can be set to dither 24-bit digital signals to 16-bit. The 788T uses a proprietary pseudo-random dither routine for accurate bit rate reduction. Dither can be defeated in the Bit Depth Setup Menu option. Without dither, 24-bit audio is truncated to 16-bit, meaning the least signiﬁ cant 8 bits are discarded.

Once a ﬁ le is recorded its sampling rate and bit depth can not be changed in the recorder. File conversion must be done in another environment, such as an audio workstation.

Audio File Formats

The 788T records audio to the industry-standard Broadcast Wave ﬁ le format, either monophonic or polyphonic. Additionally, the 788T will also playback ﬁ les in the WAV, MP2, or MP3 formats. The 788T will also read ﬁ les with the .BWF extension.

.WAV

The 788T writes AES-31 Broadcast Wave formatted ﬁ les. The audio ﬁ les created by the 788T include additional information (Metadata) in the ﬁ le’s header, BEXT (Broadcast Audio Extension) and iXML data chunks. See Appendix 2 – Metadata Implementation. Software that does not recognize these additional broadcast wave data chunks will simply ignore them.

File Type

The 788T has two ﬁ le type options for recording, WAV mono and WAV poly. Select the ﬁ le type in the Setup Menu option REC: F ILE T YPE.

Monophonic

When WAV Mono is selected, the 788T will generate a separate audio ﬁ le for each recorded track. The mono ﬁ les generated by the 788T have ﬁ le names similar to T01_1.WAV and T01_2.WAV. The ﬁ le name sufﬁ xes, _1 and _2, identify the track number of the ﬁ le. If a take contains 10+ mono tracks the tracks will be sufﬁ xed with _A (10), _B (11), _C (12).

Polyphonic

When WAV Poly is selected, the 788T will generate one audio ﬁ le for each take. All recorded tracks are interleaved into this single ﬁ le.

Wave Agent Beta allows for the splitting (de-interleaving) of polyphonic ﬁ les and combining (merging or interleaving) of monophonic sibling ﬁ les into a single polyphonic ﬁ le. See Wave Agent Beta.

Recording and Playback5

Take Management

A Take is a single recording which is composed of one or more audio ﬁ les.

788T/788T-SSD User Guide and Technical Information

For polyphonic wav ﬁ le recordings, a take is represented by a single polyphonic ﬁ le generated at the time of recording. The single polyphonic ﬁ le contains all the tracks of the take. In this case, since the take is represented by this one ﬁ le, its name is the same as the ﬁ le’s name.

In the 788T, a polyphonic take/ﬁ le name consists of a scene name, take number, and a ﬁ le extension. For example, for scene S01, take T01, the polyphonic ﬁ le name and take name are both S01T01.wav.

For monophonic wav ﬁ le recording, a take is represented by a group of monophonic ﬁ les generated at the time of recording. Each monophonic ﬁ le represents an individual track of the take. In this case, since the take is represented by several ﬁ les, its take name is the same as any of the constituent ﬁ les’ names except with the track number sufﬁ x is replaced by ‘_X’.

In the 788T, a monophonic ﬁ le name consists of a scene name, take number, track number sufﬁ x and a ﬁ le extension. See Appendix 3 – File Naming. For example, for scene S01, take T01, comprising of 4 tracks, the monophonic ﬁ le names are S01T01_1.wav, S01T01_2.wav, S01T01_3.wav, S01T01_4.wav, and the take name is S01T01_X.wav.

Scene Name/Numbering

Scene names are selected for use from a scene name list. This list is managed in the Setup Menu option REC : S CENE NAME/NUMBER. Any number of scene name lists can be generated and these can be made up of any number of scene names. The advantage of scene name lists is that frequently used scene names can be compiled before production starts.

Scene names are made with alphanumeric characters, including “_ ” and “-” and can be any length between zero (0) and nine (9) characters. Scene numbers help to match audio with the corresponding scene in a production. Scene names can also be used to identify other items, including roll number, recording date, artist name or any other descriptor as required.

Scene names are user-selected in the Setup Menu and do not change until changed by the user.

To change scene numbers:

1. Enter the user menu and navigate to the Scene Name/Number option.

Take Numbers

Take numbers are integers between 01 and 99, 999, with or without preceding zeros, which increase by one each time a new ﬁ le is recorded. Take numbers can be set with or without a take separator, such as the character “-” or “T”. The take separator can be used to clearly identify the take number within the ﬁ le name. Take numbers are managed in the Setup Menu option REC: T AKE N AME/NUMBE R. Take numbers can be incremented and decremented in the Take List.

If the 788T detects a take/ﬁ le with the same name in the destination folder, a letter sufﬁ x, starting with “A” is added to the take/ﬁ le name, before the extension.

To change take numbers:

1. Enter the Setup Menu and navigate to the Take Name/Number option.

2. Use the REWIND (<<) and FAST FORWARD (>>) soft keys to move among decimal places

and to jump to the single alphanumeric take spacer character. Use the PLAY key to reset the take number to 1. Characters are entered from left to right and deleted from right to left.

Do not use the underscore (“_”) character as a take spacer. Since this character is used to designate mono tracks when recording mono WAV ﬁ les can cause confusion.

3. The Rotary Switch or the soft keys are used to choose characters/numbers. Press the soft

Check Mark (TONE) key or press in on the Rotary Switch to save the character and move to the next position.

From the Setup Menu the action for take resetting is controlled by the following options:

Alternatively, the last take can be identiﬁ ed as a False Take from within the Take List. This can be done by decrementing the take number to match the most recent recorded take’s ﬁ lename.

Files that have been conﬁ rmed as false takes are moved to the FALSETAKES folder. When recording to internal drive, CompactFlash, and external FireWire storage devices, ﬁ les determined as False Takes will be moved to the FALSETAKES folder on each storage media that the ﬁ le has been written to. This folder sits in the drive root. False Takes will remain on the drive until the FALSETAKES folder is emptied.

Emptying the False Take Folders

Files that have been moved to the False Take folders can be permanently deleted from each media in the Drive Options Menu by selecting EMPTY T RAS H. Each drive has its own False Take folder and they are permanently deleted independently. Once the False Take folder has been emptied, any ﬁ les it contains are permanently deleted and cannot be recovered. See Emptying the Trash for more details.

Track Naming

Each track in a ﬁ le, whether monophonic or polyphonic, can be named with a unique, descriptive track name. Descriptive track names such as ‘radio mic 1’, ‘boom 2’ or ‘John Smith’ are more helpful to editors than track numbers. Track names with up to 26 characters are managed in the Setup Menu option REC : TRACK NAMES. The track names selected prior to recording are stored in the Broadcast Wave Extension (BEXT) data as well as in the iXML data.

When Setup Menu option CONNECTION MODE is set to C-LINK METADATA SHARING, editing the track name on the C.Link master unit will also change the respective track name on the C.Link slave unit.

Generating Sound Reports

A sound report can be generated for all the ﬁ les in any folder on the 788T. There are two methods for creating a sound report. Each method will create a CSV ﬁ le named SOUND_REPORT.CSV in the target folder.

To generate a sound report in the current recording folder on all media, simultaneously press the STOP and MENU buttons. A message will appear indicating that the reports are being created, followed by a message indicating that the reports were created successfully. Push the TONE button to accept this.

Using the STOP + MENU shortcut to create a sound report on each media will create a report that derives information from the primary media depending on what is selecting in REC: MEDIA SELEC T. This method might not be preferred if different tracks are routed to different media with Track-to-Media routing.

It is also possible to generate a single sound report in a single folder.

1. Press the HDD key to access the Take List.

2. Press the soft DRV (HDD) key to access the Drive Directory.

788T/788T-SSD User Guide and Technical Information

Synchronization and Timecode

Synchronization

A stable sample clock source is essential for high quality digital audio. Setups involving multiple digital recording/playback devices often require that all devices are locked to a common clock reference to ensure they are synchronous, i.e. run at the same speed and in phase with one another.

The 788T can act as either a clock master, where it is the provider of word clock, or as clock slave, where it locks its internal word clock to a received external master reference clock. Incorrect word clock settings can result in poor audio quality, sample clock timing errors, and time code drift.

The 788T uses a rock-stable word clock and PLL circuitry to generate its internal clock frequency. The 788T only uses its own word clock during playback, ignoring AES clock and video sync during playback.

Clock Master

The 788T provides a master clock reference via its WORD OUT BNC connector or from any of its balanced digital AES3 outputs. The difference between Word Out and AES is deﬁ ned below.

Word Out

Word clock is purely a signal for sync purposes and contains no audio information. It is a square wave signal with a frequency equal to the 788T’s internal sample rate. The 788T word clock output is always active. Connect the 788T’s WORD OUT to the slave device’s WORD INPUT.

AES Digital Outputs

AES digital outputs provide both PCM audio data and word clock within the same stream. A compatible slave device can derive its reference clock from this stream at the same time as receiving the digital audio. This is ideal for recording the digital outputs of the 788T to a slave device with AES/ AES3id inputs. No additional Word Clock connection is required.

Clock Slave

The 788T can accept external clock sources as its word clock reference. The 788T accepts word clock, AES clock, and various video sync formats for clock. Audio devices often output word clock or AES digital audio. Cameras and video decks often provide video sync (video black) which can be used for word clock.

When the 788T is slaved to an external clock source, be certain that the signal is stable. Loss of sync signal during recording can cause the 788T to revert back to its internal set sampling frequency causing audio glitches and/or sync issues later in post.

The 788T’s sync reference is selected in the Rec: Sync Reference Setup Menu. The options for sync sources are:

• Internal

• Word Clock

• Video Sync

• Digital Inputs 1-2

• Digital Inputs 3-4

• Digital Inputs 5-6

• Digital Inputs 7-8

Synchronization and Timecode6

788T/788T-SSD User Guide and Technical Information

Internal

The 788T generates its own clock at the set rate and disregards all external clocks connected. When set to Internal, the Sample Rate Converters are activated for all incoming AES signals.

Sample Rate Converters

The 788T has high-quality, hardware sample rate converters (SRCs) on each of its AES/EBU digital inputs. The SRCs apply to AES signals when the Setup Menu option RE C: S YNC RE FERENC E is set to Internal. The 788T’s digital inputs accept AES signals with sampling rates from 32 kHz to 192 kHz. With the sample rate converters active, each digital input can be connected with signals of any sample rate without having to word clock all of the devices together.

The SRCs are only active when needed; when not needed they are deactivated. To use digital inputs without the SRCs active, set the REC: S YN C REFERENC E Word Clock Input, Video Input, or to an AES input pair.

Word Clock Input

Synchronization and Timecode6

When the 788T is set to receive external word clock, the 788T locks to a valid clock signal connected to the Sync Input connector. If a valid word clock is detected, ‘W’ is displayed in the LCD. If no valid word clock is detected, the input activity LED rings will ﬂ ash yellow and the Lock indicator, ‘W’ does not appear.

Video Sync

The 788T can lock to valid video sync sources, including composite NTSC, PAL and Tri-level connected to the Sync Input connector. If valid video sync is detected, ‘V’ is displayed in the LCD. If no valid video sync is detected, the input activity LED rings will ﬂ ash yellow and the Lock indicator, ‘V’ does not appear.

Digital Inputs 1-2, 3-4, 5-6, 7-8

The 788T can be set to derive word clock from valid digital input pairs even if the equivalent numbered analog input pair has been selected for recording. For example, sync reference is set to digital input 1-2 and inputs 1 and 2 are both set to MIC. If a valid digital input sync source is detected, ‘D’ is displayed in the LCD. If a valid digital input is not detected, the Input Activity Ring LED associated with the selected digital input sync source will ﬂ ash yellow and the Lock indicator, ‘D’ will not appear.

If digital audio is connected to the 788T from more than one digital source, you must lock these sources together to a common reference, otherwise differences between the sources’ clocks will cause unpredictable results. Sample rate conversion is not active for digital inputs unless the sync source is set to Internal.

1. Loss of clock reference: When using external clock and the clock source is removed, the portion of the ﬁ le recorded after the loss of the clock source may not play back at the proper speed. For ﬁ le integrity, it is recommended that you set the 788T to the same sample frequency as the external clock source. Loss of the clock signal in this case will likely cause a short glitch in the ﬁ le as the internal generator takes over, but the ﬁ le may still be usable since it will play back at nominally the correct speed.

2. The 788T LCD main display screen shows the sample clock rate of the incoming word clock or digital input reference when locked (‘D’ or ‘W’ indicators are ON).

3. If multiple Digital Inputs are used, it is best practice to set the sync source to Internal. This will activate the hardware Sample Rate Converters on the 788T Digital Inputs and ensure that all inputs are synchronized.

Time Code

The 788T holds accurate time code for up 4 hours between battery changes using its internal, Li-Ion time code battery. After 4 hours without power, the 788T reverts to a slightly less-precise time-of-day crystal to maintain the date/time of the unit. This time code battery is charged from internal or external power whenever the 788T is powered up.

If the time-of-day clock is reset during the production day or if the time code mode is changed from 24 hour run to another mode and back, the time code value will change. You must re-jam all time code devices to ensure proper synchronization.

File-based recorders place a single time code stamp in the BEXT and iXML chunks of an AES31 (Broadcast WAV) ﬁ le. The 788T generates SMPTE time code from this number and extrapolates it based on the time code frame rate for playback.

Files recorded on the 788T will always begin and end on a 0 frame. Pre- or post-roll (respectively) will be applied automatically to accomplish this. Time code stamps will be adjusted accordingly. This simpliﬁ es synchronization in post-production.

Frame Rate

A single time code frame rate is selected in the Setup Menu option T I MECODE: FRAME RATE.

Sound Devices strongly recommends that the appropriate frame rate be conﬁ rmed with Post Production prior to the start of production.

Synchronization and Timecode6

The 788T supports all of the common production time code frame rates, including:

• 23.976 – This frame rate is most often used in productions shooting high deﬁ nition video.

Counts 0.1% slower than real time.

788T/788T-SSD User Guide and Technical Information

• 24 – Frame rate of standard ﬁ lm. Sometimes, it is also used in high-deﬁ nition video production

when the video ﬁ les go through a telecine process.

• 25 – The frame rate of PAL video. Most often used in video and ﬁ lm production in Europe and

other PAL-based environments.

• 29.97 – The frame rate of NTSC color video. Most often used in the USA and other NTSC based

nations. Counts 0.1% slower than real time.

• 29.97DF – The frame rate of NTSC video modiﬁ ed to match real time. Drop frame time code

is primarily used in the NTSC broadcast industry where it is often required that the time code of ﬁ nished program material reﬂ ects actual real time duration. Drop frame is not common for production time code.

• 30 – Originally, the standard frame rate for American black and white television. Today, it is

most often used to sync sound to ﬁ lm where transfer to NTSC video is expected.

• 30DF – This is a rarely used non-standard frame rate. Do not use unless speciﬁ cally requested

by production.

• 30+ – This setting is speciﬁ c to Sound Devices recorders. Records at 48.048 sampling rate at 30

frames per second but stamps the ﬁ le at 48 kHz, 30 frames per second.

Synchronization and Timecode6

Sound Devices Wave Agent Beta for Mac OS and Windows computers allows users to change the Frame Per Second Stamp of any ﬁ le. This is useful when the wrong Frame Rate was selected at the time of recording. See Wave Agent Beta for more details.

F Sampling Rate Modes

48.048k and 48.048kF

The 48.048kF mode (F stands for fake, faux, Fostex—take your pick) is a speciﬁ c compatibility mode for use with the Fostex DV40 software (1.74 and previous), Avid, Final Cut Pro, and other post-production environments that do not recognize audio ﬁ les written at 48.048 kHz. In this mode ﬁ les are recorded at a 48.048 kHz sampling rate but are stamped at 48 kHz. When played, they will play back

0.1% slower than real time.

One use for the 48.048kF mode is to force a 0.1% speed reduction (pull down) of audio to match MOS-telecined ﬁ lm (24 fps-to-NTSC) in non-linear edit systems, such as Avid or Final Cut Pro. Since the ﬁ le is stamped as a 48 kHz ﬁ le, the edit system will play it back at 48 kHz and not at 48.048 kHz. This “audio pull down” will match the transferred picture without the need for an intermediate step through other software to create the pull down.

The time code frame rate (actual recording rate) is forced to 30 ND in 48.048kF mode. The LCD display will show 30 ND during recording. No other frame rate is available in 48.048kF mode.

788T/788T-SSD User Guide and Technical Information

The audio ﬁ le, however, is stamped with a 29.97 ND frame rate, along the 48 kHz sampling rate. It will appear as if the ﬁ le was originally recorded at a 48 kHz sampling rate at a TC rate of 29.97 ND.

on playback, file appears at 48 k, 29.97 ND

Fostex DV40

When using ﬁ les recorded in the 48.048kF mode in with a DV40 with early software, set the DV40 time code frame rate to 29.97ND. Time code stamps will properly match the original time code start times.

47.952k and 47.952kF

Both 47.952 and 47.952kF settings use a record sampling rate of 47.952 kHz, 0.1% lower than 48 kHz. The 47.952kF mode, however, identiﬁ es the ﬁ le as being recorded at 48 kHz. Additionally there are two frame rate options in 47.952kF mode. The time code frame rate can be set to 23.97 while the ﬁ le is identiﬁ ed as 24ND or it can be set to 29.97ND while the ﬁ le is identiﬁ ed as 30ND. By default, when

47.952kF mode is selected the frame rate is changed to 29.97ND and identiﬁ ed as 30ND unless the Frame Rate was already set to 23.97 in which case it will remain at 23.97.

96.096k and 96.096kF

Both 96.096 and 96.096kF settings use a record sampling rate of 96.096 kHz, 0.1% higher than 96 kHz. The 96.096F mode is a rarely used workﬂ ow and should only be selected if speciﬁ cally requested by production. It is essentially the high sampling rate version of 48048F mode. The takes are recorded at

96.096 kHz but are stamped at 96 kHz. Additionally, in 96.096F mode, the time code rate is restricted to 30ND, while the ﬁ le is identiﬁ ed as 29.97ND. It is important to note that most productions will not accept ﬁ les at 96 kHz rates.

Time Code Modes

The 788T includes the following time code modes:

Off

The time code generator is disabled. The front panel time code display is blank.

Free Run:

The internal time code generator runs continuously without regard to the Record mode. Any time code value can be used as the start value by “jamming value” in the jam menu.

Record Run

The time code generator runs only when the 788T is recording. Time code in this mode defaults to 00:00:00:00 at power-up. When switching to Record Run from another mode, the internal generator will stop at the last number generated. A user-deﬁ ned value can be jammed into the internal generator from the jam menu.

Synchronization and Timecode6

788T/788T-SSD User Guide and Technical Information

Free Run Jam Once

The onboard time code generator will re-jam from external time code whenever a valid, running time code signal is connected to the TC input. Similar to Free Run mode, the generator runs continuously without regard to Record mode. For a jam to occur, the time code signal must be disconnected and re-connected to the time code input. Free Run Jam Once is useful when using the recorder as a slave, although one of the External TC modes may be more appropriate for slaved operation.

24 Hour Run

Identical to Free Run with the exception that the generator will automatically jam itself from the time-of-day clock on power-up. The generator will also re-jam if the time-of-day clock is reset. Once jammed, the generator will run continuously from the time code clock, not the time-of-day clock.

Ext TC

The internal time code generator follows an external time code signal appearing at the time code input. In all of the external time code modes, the time code value set on the 788T appears as the recorded ﬁ le’s time code rate value.

Synchronization and Timecode6

Ext TC/cont

The internal time code generator follows an external time code signal appearing at the time code input. If the external time code is removed, the internal generator continues to run to preserve continuous time code. Useful for time code transmission over RF where RF “hits” may interrupt time code.

Ext TC-Auto Record

The internal time code generator follows the external time code signal appearing at the time code input. When external code advances, the 788T enters Record mode automatically. When the external code is stationary, the 788T generator pauses and recording is stopped. This is appropriate when dual-system sound is used with video cameras set for Rec Run time code. The video camera will function as master time code and the recorder “transport” will follow the video camera transport.

Ext TC/cont-Auto Record

The internal time code generator follows the external time code signal appearing at the time code input. When external code advances, the 788T enters Record mode automatically. When the external code is stationary, the 788T generator pauses and recording is stopped. If the external time code is removed the internal generator continues to run to preserve continuous time code. Useful for time code transmission over RF where RF “hits” may interrupt time code. This is appropriate when dualsystem sound is used with video cameras set for Rec Run time code. The video camera will function as master time code and the recorder will follow.

Free Run - Auto Output Mute

Like Free Run mode, the internal time code generator runs continuously without regard to the Record mode. However, time code signal is only output during record and playback. Time code signal is muted while transport is stopped. Although time code signal is muted while transport is stopped, the time code generator is not stopped. When recording is started again, time code will reﬂ ect the amount of time elapsed since the last recording was stopped.

Since time code is muted when transport is stopped, Free Run - Auto Output Mute mode will not trigger recording of Sound Devices products that are set to an external auto-record / continuous mode. The 552 and PIX 240 external auto-record modes are always continuous.

788T/788T-SSD User Guide and Technical Information

Time Code Hold Off

Time Code Hold Off is designed to eliminate unintentional takes from occurring by specifying an amount of time to wait (“hold off”) before beginning to record when using an external auto-record time code mode. The value of Time Code Hold Off needed is dependent on the start and stop sequence of the master time code source.

To use the Time Code Hold Off feature:

1. Access the Setup Menu option TIMECODE: HOLD OFF.

2. Set a value between 0 and 8 seconds in .1 second increments using the soft Up and Down Arrow (Menu and HDD) keys or the Rotary Switch. 2.0 Seconds is the factory default.

3. Save the selected value by pressing the soft Check Mark (Tone) key or by pressing in on the Rotary Switch.

4. Exit the Setup Menu by pressing the soft X (Brightness) key or the Stop key.

5. Begin rolling time code from the master time code source.

6. The 788T recorder will display the Record Pending message immediately after detecting a time code signal.

7. When the selected Hold Oﬀ value has elapsed, the 788T will begin recording.

Things to consider when using Time Code Hold Off:

• This feature only applies to Ext TC - Auto Record and Ext TC/Cont - Auto Record modes.

• If Pre-Roll is set, it will be applied. Pre-Roll will only capture audio from the initial detection of

a time code signal. If no Pre-Roll is selected, the ﬁ le will begin after the Hold Off time expires. It is best practice to set Pre-Roll, in the Setup Menu option REC: PRE-RO LL T I ME, to a value greater than the selected Hold Off value. This ensures that audio is captured from the moment a time code signal is detected and unintentional ﬁ les triggered by short bursts of time code are not generated.

Jam Zeros

This menu selection resets the internal generator to zero.

Edit Value / Jam Value

The EDIT VALUE selection allows the user to set any valid time code value (00 : 00 :00: 00–2 3 : 5 9 : 5 9 : 2 9) and the JAM VALUE selection jams the internal generator to that value. The initial screen of the ED I T VAL UE selection shows the currently set value as well as the current time code setting of the 788T. Press the Rotary Switch or the enter key (tone key) to beginning editing the hour value. Once the hour is set, press the Rotary Switch to continue editing the rest of the values. Use the JAM VALUE selection to jam the internal time code generator to this saved value.

User Bits

The 788T has seven user-selectable user bit modes. Time code user bits are a portion of the time code data which can be set to a custom value. Commonly, user bits carry information such as the date, take, sound roll, or camera roll number.

The 788T can automatically ﬁ ll all - or a portion of - the user bit value automatically. To select the format used for automatic user bit values, select Setup Menu option TIMECODE: USER BITS.

User-editable portions of the user bits are edited from the EDIT U-B IT selection in the jam menu. If there are no user-editable portions of the selected user bit mode, “NO USER EDIT S “ will appear in the screen.

NTSC Standard Def Video Production

NTSC video uses a frame rate of 29.97 frames per second. Thit leaves 108 frames per hour unaccounted. To keep 29.97 time code in sync with “clock” time, the concept of “drop frame” was devised: Two frames are dropped at the beginning of each minute that is not divisible by 10 (54 x 2 =

108).

To sync the 788T time code to a video camera, ﬁ rst determine if the camera is in drop or non-drop frame mode. If unsure about what setting to use, check with post-production.

1. Set the 788T to either 29.97DF or 29.97 respectively. Video for NTSC broadcast is generally dropframe. Whether at drop or non-drop rates, all time code devices must be set to the same rate.

2. Jam the camera using a LEMO-5 to BNC (or XLR, depending on what connector the camera uses) adapter cable connected to the time code input on the video camera.

3. Set the camera to free run time code. The 788T time code should appear in the time code display on the camera.

4. Disconnect the time code cable.

The camera and recorder time code should now be running in sync. Check after roughly 5 minutes to be certain synchronization is maintained.

Most video cameras will not maintain stable time code when shut down. Re-jam time code if the camer has been powered down since the last time time code was jammed.

Headphone Output

The 788T headphone output is a ﬂ exible tool for monitoring audio in the ﬁ eld. The 788T allows the user to monitor inputs and tracks in a wide range of combinations. MS stereo and B-format surround decoding are also available as headphone monitoring options.

The headphone output is independent of the Output Buses and audio sources can be routed to headphones independent of routing assignments to output buses. The headphone output source is sent to both the 1/4-inch and the 3.5mm TRS jacks.

The 788T is capable of driving headphones to extremely high sound pressure levels. Hearing experts advise against exposure to high sound pressure levels for extended periods.

Selecting Headphone Sources

The headphone source is displayed on the main LCD screen ( ). The 788T comes from the factory with several preset headphone audio source combinations selected by the Rotary Switch. These selections include inputs and tracks. Turn the Rotary Switch to select among the available headphone monitoring sources.

Setting Headphone Source Options

The user can deﬁ ne which headphone routings will be available when turning the Rotary Switch. Headphone monitoring sources can be set from various preset combinations of inputs and tracks, including stereo MS decoding, and SoundField B-Format surround decoding. The order of monitor sources is also user selectable.

To set the available headphone source options:

1. Enter the HP : MONITOR MODES Setup Menu option. Once you enter the Monitor Modes menu you will immediately be in slot-1.

2. Turn the Rotary Switch to select the source you wish to appear ﬁ rst in your Headphone moni- tor list.

Assigning any track to a monitor channel will unassign all inputs from that channel. Inversly, assigning any input to a channel will unassign all tracks from that channel.

Headphone Source as Outputs

The left and right program of the headphone monitor can be selected as an output source. This allows the user to send the selected headphone monitor source to third party devices. Output muting and the Headphone Volume control have no effect on the signal at the outputs. Headphone program is sent to the outputs before the CL-9 is introduced in the signal path.

Input Solo (PFL)

Inputs are quickly soloed (pre fade listen) in headphones by pressing its corresponding Input Selector Switch. This will latch on the Input Settings Window and solo the input in the headphone monitor. To exit the Input Settings Window and return to the last headphone monitor program, press the selected Input Selector Switch again.

If momentary action is desired, press and hold the Input Selector Switch for one second or longer. If the Input Selector/Solo Switch is held for 5 or more seconds “Hold” will appear on the screen and the soloed input will remain in the headphone monitor until either another headphone monitor mode has been selected with the Rotary Switch or with the Input Selector/Solo Switch. If it is desired to access the Input Settings Window without soloing the input, disable the PFL function in the Setup Menu option INPUT : P FL FUNCTION.

When a CL-8 is attached a user can quickly solo an input by pressing the A and B buttons from the CL-8 Main View. See CL-8 for more details.

v. 3.02 Features and specifications are subject to change. Visit www.sounddevices.com for the latest documentation.

788T/788T-SSD User Guide and Technical Information

When a CL-9 is attached a user can quickly solo an input by pressing the input’s rotary encoder from the CL-9 Top Panel. See CL-9 Linear Fader Controller section for more details.

If the selected input is stereo linked, both of the inputs will be soloed in the headphone monitor.

MS Stereo Monitoring

The MS stereo mode decodes discrete Mid-Side stereo signals to a left/right stereo signal for monitoring purposes. This allows for a proper stereo signal to be monitored in the ﬁ eld while discrete M and S signals are recorded for later post production. For the MS decoder to operate properly, the Mid signal is connected to either of the odd inputs (1, 3, 5, 7) and the Side signal is connected to the even inputs (2, 4, 6, 8). The amount of stereo “spread” is ﬁ xed at a 50/50 percentage from Mid to Side signal.

If MS is selected for input linking, do not use MS stereo monitoring. This would result in two MS decoders being inserted in the signal path. The resulting audio in the headphones would not be an accurate stereo image.

SoundField B-Format Surround Monitoring

SoundField B-format is a four channel surround sound format generated by SoundField surround microphones. The 788T can accept the four signals output from a SoundField microphone and record each to its own track.

When recording four-channel B-format audio, the 788T headphone monitor can decode the B-format signal into L/R stereo. The 788T constructs a stereo signal using the W, X, and Y signals of the Bformat. The Z-axis signal is not used. Similar to the 788T’s MS stereo monitoring, the stereo width is ﬁ xed for headphone monitoring.

To record and monitor B-format signals, connect signals as follows:

SoundField  788T  Resulting File Name (for monophonic ﬁ le type) W signal  input 1, track L  FILE _ 1.WAV X signal  input 2, track R  FILE _ 2 .WAV Y signal  input 3, track A  FILE _ 3 .WAV Z signal  input 4, track B  FILE _ 4.WAV

SoundField ﬁ les generated in other recorders or software applications can be copied to CompactFlash or the 788T internal drive and can be played back and monitored in stereo. Make certain that channel assignments follow the order above for proper headphone decoding. If multiple monophonic SoundField .WAV ﬁ les are named using the “_W, _X, _Y, _Z” sufﬁ xes, the 788T will recognize that these are multiple monophonic B-format ﬁ les and will play them back in the proper track order.

The 788T can play back monophonic or polyphonic B-format ﬁ les.

Monitoring and Metering7

There are two B-format monitoring selections, one for inputs and one for tracks. They are listed as INPUT B-FMT STEREO and TRACK B-FMT STEREO. For most recording and playback applications the track monitor selection is appropriate. If the user wants to hear the inputs at all times, the input monitor selection is appropriate.

Headphone Warning Tones

The 788T generates audible beeps, or warning “bells”, in the headphone monitor when an error has occurred. The speciﬁ c error will be reported on the LCD. The output level of the warning bell can be adjusted from Off or -60 to -12 dBFS in the Setup Menu option HP: WARNING BELL LEVEL .

Recording Start and Stop Bells

If enabled in the Setup Menu option HP: REC ORD/STOP B ELL, the start of recording can be indicated audibly by a single, 440 Hz tone sent solely to headphones. When recording is stopped, two 220 Hz tones will be sent to the headphones.

Low Battery Warning

Warning tones are sent to the headphones when either the attached battery or external power supply voltage reaches their low warning levels (6.9 V for the attached Li-ion, 10.5 V or user-selectable in the Setup Menu option POWER: EXT LOW BAT T VO LT). The Low Battery Warning is three short 880 Hz tones that are sent every 20 seconds.

When warning bells are turned Off, no tones are sent to headphones, including the Low Battery Warning.

Headphone Power Up Gain

The 788T’s headphone level is adjustable from Off, -40 dB to 26 dB in 2 dB increments. The Setup Menu option HP: POWER UP GAIN sets the headphone level control upon start up to: Off, the Last Gain setting used, or at Midpoint Gain (0 dB).

Meter Scale

There are two factory meter scales, Standard and Zoom. Standard is a non-linear scale which covers the range -44 to 0 dBFS. Zoom provides a high resolution meter scale focused on the range from -32 to 0 dBFS. At factory default, Standard is the set meter scale and Zoom is the Favorite meter scale. To switch between Standard and Zoom meter scales press and hold the LCD Backlight key for two seconds or longer. See Favorite Mode for more details.

Standard Meter Scale Resolution

788T/788T-SSD User Guide and Technical Information

Zoom Meter Scale Resolution

The LED Output Meter uses a tri-color scale, allowing the track levels to be easily viewed and monitored. The standard scale is separated by Green LEDs to indicate normal input-to-track activity from

-44 to -12 dBFS, Orange LEDs to indicate a hotter input-to-track activity from -9 to -6 dBFS, and Red

Monitoring and Metering7

LEDs to indicate that the input-to-track activity is approaching clipping from -3 to 0 dBFS.

The meter scale can be customized by the user to meet the requirements of a speciﬁ c application. Each LED can be set to illuminate at a speciﬁ ed dBFS level. Follow these steps to enter a customized meter scale.

All 12 track meters can be viewed at the same time from the Track Setup Window. To enter the Track Setup Menu, press the INPUT key. The metering ballistics and peak hold time settings are deﬁ ned in the Setup Menu and apply to both the Front Panel Output Meter and the Digital Meter View.

Meter Ballistics

The output meter can be set to display any of three types of meter ballistics: VU, Peak, and a combination of VU and Peak. The meter ballistics are selected in the Setup Menu option MET ER: BAL LIS TIC S.

Monitoring and Metering7

VU (Volume Units)

Ballistics correspond closely to how the human ear perceives loudness and provides a good visual indication of how loud a signal will be. In VU mode, the attack and decay of the meter signal is 300 msec. While giving a very good visual indication of perceived loudness, VU meters give poor in-

788T/788T-SSD User Guide and Technical Information

formation on actual signal peaks and thus not ideal for use during recording. In VU mode, the front panel meter labeling is in volume units.

Peak Only

Peak-reading ballistics correspond to actual signal maximums, but don’t necessarily correspond to perceived signal loudness. A peak meter has a near-instantaneous attack to display maximum signal amplitude and a slow decay to allow the user to see them. Peak metering is essential for digital recording, since signal overload can cause immediate distortion. The peak meters front panel markings are calibrated in dBFS, decibels relative to full-scale digital signal.

Peak/VU

Peak/VU mode will display VU and Peak level information simultaneously. In this mode, the perceived loudness (VU) is displayed as it is in VU mode, and the Peak level is indicated by the uppermost LED. With this combination the user gets the best of both VU and Peak metering by seeing both the perceived loudness and the peaks of the signal at the same time. Peak/VU is the factory default.

Peak Hold Time

Monitoring and Metering7

Peak-hold indicators are useful for metering in applications when an overload condition is unacceptable or when program material must not exceed a prescribed threshold. The Peak Hold Time is user selectable in the Setup Menu option METER : PEAK HOLD TIME. The peak LED will hold its position for the selected duration from 0 to 5 seconds in .1 second increments. This allows for easy viewing of peak values that could otherwise go unnoticed.

Input Activity Ring LEDs

The LEDs surrounding the Input gain pots indicate the input activity for each input respectively. The LEDs illuminate in various colors and intensities to represent the state of each input. Green = signal activity, Yellow = limiter activity (pre- or post-fade), Red = signal overload (clipping). When a fader accessory is connected the Input Activity Ring LEDs will only indicate pre-fade limiting.

If a digital input has been selected and the 788T detects a valid digital signal, the Input Ring LEDs will follow the normal red and green LED behavior. The Input Activity Ring LEDs can be defeated by color in the Setup Menu option METER: I NPUT LED RING MODE.

When Mix Assist is enabled, the Input Activity Ring LEDs will illuminate green on automixed inputs to indicate an open mic. This behavior overrides the metering behavior of the Input Activity Ring LEDs. See Mix Assist

Headphone Peak LED

The headphone circuit has an indicator for peak overload. Monitoring without a visual indication of headphone clipping may mislead the operator into thinking that the record or playback signal is distorting.

788T/788T-SSD User Guide and Technical Information

Tone Oscillator

The tone oscillator can be used as an aid to lining up levels. Both tone level and frequency are user selectable. Reference level is adjustable over a range of 40 to 0 dBFS in the Setup Menu option TONE: LEVEL. The tone frequency is adjustable from 100 to 10,000 Hz in increments of 10 Hz from the Setup Menu option TONE: FREQUENCY. Standard tone levels vary according to the practices and needs of production and post-production, but are generally in the –20 to 12 dBFS range.

The tone oscillator is activated by pressing the latch on, pressing again will deactivate the tone signal. Tone is routed where speciﬁ ed in the Setup Menu option TONE: MODE. Routing choices include: Outputs only, Outputs and Tracks, Tracks only, or no tone routing (disabled). When routed to Tracks, all selected record tracks will receive the tone signal. Changes to tone oscillator settings made while tone is latched on do not take affect until tone is turned off.

Tone mode options are available with “L-Ident” (Left Identify). When an L-Ident Tone Mode is selected and tone is engaged, the amplitude of the tone in some channels will oscillate between the set tone level and -20 dB at a rate of 1 Hz (once per second). This feature is useful to verify connections to outboard gear (i.e. a camera). L-Ident tone sent to record tracks will oscillate the tone signal on Track L. L-Ident tone sent to outputs will oscillate the tone on all odd-numbered outputs (1, 3, and 5).

To record tone at the head of a take, activate the tone signal then press the REC key. From the factory, subsequent presses of the TONE key are locked out to prevent tone from being inadvertently recorded. Tone can be activated while recording by following these steps.

1. Enter the Setup Menu option FILE: MARKER MODE and set it to disabled.

2. Press the REC key to begin the recording.

3. To record tone, Press and hold down the REC key then press the TONE key. To latch tone, press and hold the Tone key for 2 seconds, press again to release. Once tone is generated the REC key can be released.

The tone oscillator can be activated anytime during recording by setting the TO N E: RE C ORD LO C K feature in the Setup Menu. Press the Tone key anytime to generate a tone signal. Please note that when enabled, any slight press of the tone key will generate tone and override any program material where tone has been routed to, including record tracks.

File Management and Storage8

File Management and Storage

The 788T, like a computer, saves audio recordings to a ﬁ le system containing ﬁ les and folders. The 788T/788T-SSD formats its internal drive, CompactFlash cards, and attached external drives in the FAT32 format as single drives named “788T INDD”, “788T CF”, and “788T EXTHDD ,” respectively.

Automatic File Splitting

While it is possible to have thousands of ﬁ les on the 788T storage volume(s), the largest any single ﬁ le may be is 4 GB. See Appendix D – FAT32 and Maximum File Size. The 788T automatically splits an audio ﬁ le before the 4 GB size is reached (2 GB is factory default) and begins writing to a new ﬁ le. When joined in an editing program, these ﬁ les match seamlessly with no samples lost. Maximum File Size can be selected in the Setup Menu option FILE: MAX SIZE of 512 MB, 1 GB, 2 GB, and 4 GB. The 512 MB size allows the user to break an audio program into CD-R sized ﬁ les for backup to inexpensive CD-R media. There is also a selection of sizes to ensure that recorded ﬁ les will ﬁ t onto common CompactFlash card capacities.

File Time and Date

Similar to a computer ﬁ le system, all ﬁ les recorded by the 788T are stamped with the creation time and date. To ensure that accurate time-of-day and ﬁ le generation dates are written for each ﬁ le, make certain that the time-of-day clock and calendar are correct.

File time and date and time code are unrelated.

1. Enter the Setup Menu option TIME/DATE: SET.

Folder Actions

All ﬁ les generated by the 788T can be saved to the Root directory, a Project Folder, a Daily (Roll) Folder, or a Scene Folder (Files are saved to the Root directory by default). File organization is managed in the Setup Menu option FILE: FOLDER O PTION S . Folder choices include TOP -LEVEL, MID- LEVEL, and BOTT OM LEVEL FOLD ERS . Folders are created when the record key is pressed. This reduces the likelihood of empty folders.

• Top-Level / Project Folder – is a root-level folder and can be set with a user-selected Project

name. Use this, for instance, as the name of the movie you are working on. The name of this folder is inserted in the <PROJECT> ﬁ eld of the iXML and bEXT chunks. See Appendix 2 –

Metadata Implementation.

The Top-Level folder can also be de-activated by selecting <NONE> from the Setup Menu. If the Top-Level folder is not used then the next lower-level folder will reside at the drive’s root. If the TOP-LEVEL folder is active then the MID-LEVEL and BOTTOM-LEVEL folders will be its sub- folders.

v. 3.02 Features and specifications are subject to change. Visit www.sounddevices.com for the latest documentation.

788T/788T-SSD User Guide and Technical Information

• Mid-Level / Tape (Roll) Folder – can be selected as a Roll folder with user-selected name or as

a <DAILY> folder, or not used. The name of this folder is inserted in the <TAPE> (Roll) ﬁ eld of the iXML and bEXT chunks. If a TOP-LEVEL folder is in use, the MID-LEVEL folder will be a sub-folder of the TOP- LEVEL folder. If no TOP- LEVEL folder is used, the MID- LEVEL folder will reside at the drive’s root. If set to <DAILY> a new folder will be created daily. When recording past midnight the 788T will prompt to make to a new daily folder.

• Bottom-Level / Scene Folder – can be selected as a <SCENE> folder which will use the name

generated from the REC: SCENE NAME/NUMBER Setup Menu, as a user-selected name, or not used at all. If no upper-level folder is in use, the BOTTOM- LEVEL folder will reside at drive’s root. If the MID- LEVEL and/or TOP-LEVEL are in use the BOTTOM- LEVEL folder will be a sub-folder.

Example: If a daily Folder is desired, set the TOP-LEVEL to <NONE> , the MI D-LEVEL folder to <DAIL Y>, and the BOTTOM-LEVEL to <NONE>. This will generate a Daily Folder in the root directory with ﬁ les directly inside the folder.

Storage Media – Internal Drive

The 788T and 788T-SSD internal drive is the primary storage medium. The large capacity and fast data read/write speeds of hard drives and solid state drives are a perfect choice when long form, high data rate recording is performed. These drives offer a good balance of speed, reliability, noise performance, and current draw.

The drive installed in the 788T is formatted at the factory as a single-partition FAT32 volume. If a drive with multiple partitions is installed, the 788T will only “see” and address the primary partition.

788T Drive Type

The 788T ships with a 2.5-inch, 5400 RPM hard drive with a SATA interface. Sound Devices has chosen the speciﬁ c mechanism for vibration and shock resistance. Most 2.5 inch drives conforming to the SATA speciﬁ cation can be substituted for the factory hard drive. When choosing a substitute hard drive, note that higher RPM hard drives draw more current, reducing battery run time. Higher speed drives may be used with the 788T, however they will not signiﬁ cantly improve performance. They will slightly increase transfer throughput with the penalty of increased current draw and reduced battery run time. The 788T can address drives with capacities up to 2 TB.

788T-SSD Drive Type

The 788T-SSD ships with an upgraded 2.5-inch Solid State Drive (SSD) with a SATA interface. Upgrading to an SSD further enhances the performance and reliability of the recorder. SSD mechanisms allow for faster transfer speeds, ultra-quiet performance, and maximum vibration and shock resistance.

Drive Replacement

The internal drive can be removed and replaced if the device fails or if a different capacity drive is needed. The internal drive is not intended to be a swappable, deliverable medium. Its SATA connector is not rated for repeated insertion and removal cycles.

File Management and Storage8

In typical service conditions Sound Devices recommends hard drive replacement once every three years.

788T/788T-SSD User Guide and Technical Information

The internal drive is mounted to the bottom-side of the recorder’s chassis and is screwdriver accessible. The drive is “suspended” in the unit with a shock absorbing foam and is attached to the main circuit board via a “ﬂ ex board”. Since the high-density circuitry and tight construction require specific electronics knowledge, Sound Devices strongly recommends drive replacement be performed by a qualiﬁ ed technician using proper ESD precautions. Drive replacement done by a qualiﬁ ed technician has no warranty implications.

File Management and Storage8

Storage Medium – Removable CompactFlash

CompactFlash (CF) is a practical, portable storage media for audio recording. Its speed, capacity, and price continue to evolve to the beneﬁ t of portable recorders. The 788T can write to and read from CF cards as either its sole storage media or simultaneously with the internal drive.

When to Use CF

The key beneﬁ ts of CompactFlash include:

• wider temperature range capability than hard drives

• greatly increased shock immunity versus hard drives

• convenient, portable, removable media

• ubiquitous card readers and transfer tools
