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

Welcome

Thank you for purchasing the 788T/788T-SSD. The ultra-compact 788T records and plays back 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 96.096 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.

Sound Devices took advantage of the best in professional and consumer electronic technologies to bring incredible feature depth with ease of use. Hard drives and CompactFlash are highly reliable, industry standard, and easily obtainable. With the ability to write to an external drive, low-cost, portable media can be delivered to post production. The removable, rechargeable battery is a standard Sony-compatible Li-ion camcorder battery pack. The 788T interconnects with Windows and Mac OS computers for convenient data transfer and backup.

The 788T is available in two models, The standard 788T ships with an internal hard drive. The 788TSSD ships with an internal solid state drive. Throughout this document both models will be referred to as the 788T., except when information is speciﬁ c to each model.

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

Input Setup and Control

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

Analog and digital inputs can be used simultaneously.

Gain is controlled by the front panel Input Gain Potentiometers. They 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 Pot to the full counter-clockwise (Off) position. The Input Gain Pots must be activated to route the respective input to a track and/or access the Input Settings Window.

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

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: PFL FUNCT ION.

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 Multi-Function 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.

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

Input Type

Select between Mic, Line, or Digital inputs using the MENU key while in the Input Settings Window.

Input Type Input Connectors Gain Range (Trim only)

Mic XLR 1-4, TA3 5-8 Off (-infinity) 0 dB to 76 dB

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 50 dB.

Phantom Power

Phantom power (48 volts) can be activated individually, for each analog input. Enable or disable Phantom Power in the Input Settings Window using the Tone key.

Phantom power can be used for both mic- and line-level inputs. Using line-level inputs with microphones is useful in high SPL environments such as concert recording. Make certain to disable phantom power with Line-level output devices susceptible to damage from DC.

High-Pass Filters

High-pass ﬁ lters on analog and digital inputs reduce sensitivity to low frequency signals. Pressing the Multi-Function Rotary Switch will engage or disengage the High-Pass Filter. Turn the MultiFunction 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 CONTRO LS is set to Fader Controls, pressing the Multi-Function 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 Trim and Input Faders

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 course 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 CONTRO LS provides two options, Trim Control or Fader Control. 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 Multi-Function Rotary Switch from within the respective input’s Input Settings Window. Pressing in on the Multi-Function Rotary Switch will toggle between Trim control and High-Pass Filter control.

When the CL-8 is attached to the 788T, the behavior of the front panel Input Gain Control adjusts trim levels and the CL-8 rotary potentiometer controls the Input Fader 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 will prevent unusually high input signal levels from clipping the analog input stage of the preamp.
