Page 16
664 User Guide and Technical Information
Polarity reversal is used to compensate for incorrectly wired balanced cables, to prevent signal cancellation when a source is dual-miked from opposite directions, or to reverse left/right with microphones in a mid-side (MS) configuration.
Phantom Power
Phantom powering is a fixed DC voltage of either 12 or 48 Volts. This voltage is resistively applied
to pin 2 and pin 3 of an input’s XLR-3F connector, relative to pin 1. In this configuration, there is no
voltage difference between signal pins 2 and pin 3.
The phantom voltage is selectable between 12 and 48 Volts from the Setup Menu item
INPUTS > Phantom Voltage. The selected voltage level applies to all inputs with phantom power
enabled. The factory default phantom power voltage is 48 V.
Phantom power can be activated for each input. To enable phantom power, enter the input’s channel screen, press the Headphone Controller, highlight either MIC-PH or LINE-PH, press Headphone
Controller again to make the selection.
Gain/Trim and Fader Relationship
Input Setup & Control
The gain of an input is adjusted by two controls, Input Trim and Input Fader. This two-stage architecture is identical to the topology of large mixing consoles and provides a great deal of control.
Input Trim is often thought of as a course gain control and the Input Fader as the fine gain control.
Input Trim (Analog)
The 664’s analog input sensitivity is set with the pop-up Trim control
knob. With the Input Fader set to unity gain (0 dB or 12 o’clock), make
the appropriate adjustments using the Trim control. Once the coarse gain
is set to the desired level, press the Trim control to hide it from the 664’s
mixing surface. Analog trim level is adjustable from +22 to +72 dB of gain.
Input Trim (Digital)
The coarse level of a digital input is set by rotating the Select Encoder in
the Input Seings Screen of an input with a digital source. The digital
trim level is displayed on the LCD when adjusted. The digital trim level is
adjustable from -20 to +50 dB.
Input Fader
10
The Input Fader is the primary control used while mixing and it aects
the level of the Input signal routed to all post-fade destinations. Use the
Input Fader to make ne gain adjustments. The fader can be aenuated
from o (full counter-clockwise position) to +15 dB above the set Trim
level (full clockwise position). To optimize gain structure for the best performance, operate input faders at or near the 0 dB (unity gain) position.

Page 17
664 User Guide and Technical Information
High-Pass Filter
Each input channel has an adjustable high-pass filter controlled by the
High-Pass Filter control. High-pass (or low-cut/low roll-off) filters are
useful for removing excess low frequency energy from audio signals.
Wind noise is a common unwanted low frequency signal that can be
reduced with the use of a high-pass filter. For most audio applications, engaging the high-pass filter is beneficial, because audio information below
100 Hz is rarely used, especially for speech reproduction.
The 664’s high-pass filter circuit features an adjustable corner (-3 dB)
frequency over a range from 80 to 240 Hz. Below 80 Hz, the filter’s slope
is 12 dB/octave. At higher corner frequency settings, the slope is 6 dB/octave. The purpose for this compound slope is to give additional roll-off at
the 80 Hz setting to reduce wind noise and low frequency rumble. The higher settings can be used to
counteract the proximity effect of directional microphones where a more gentle slope is desired.
The 664’s high-pass filter circuit is unique because of its placement before any electronic amplification. Most mixers’ high-pass filter circuits are placed after the microphone preamplifier, such that all
of the low-frequency signals get amplified. By virtue of the 664’s circuit cutting the low-frequency
signals before amplification, higher headroom is achieved in the presence of signals with significant
low-frequency energy.
When possible, attempt to equalize at the sound source with microphone selection, placement,
windscreens, and onboard microphone filtering. Many microphones have on-board high pass filters.
Use the high-pass filters on the 664 in conjunction with the microphone’s filter to increase the filter’s
slope.
The filter can be removed from the circuit completely by rotating the high-pass filter control to the
full counter-clockwise (detented) position. The high-pass filter potentiometer can be adjusted easily
and then recessed to hide it from the mixing surface.
Pan Control
The pop-up Pan Control routes inputs to the left (L) and right (R) channels of the stereo Master Bus. The pan pot has a detent in the center posi-
tion. After seing the pan, the pan control can be recessed to hide it from
the mixing surface during normal operation.
Input Linking
Input Setup & Control
Input pairs 1-2, 3-4, and 5-6 can be linked as stereo pairs. When a pair of inputs is linked:
• Each channels’ Trim Control and High-Pass Filter Control work as normal, controlling coarse gain
and high-pass ltering for their respective inputs.
• The odd channel’s Input Fader controls the post-fade level of both inputs.
11
Page 18
664 User Guide and Technical Information
• The odd channel’s Pan Control controls the balance of the stereo signal to the Master Bus. When
linked MS, the odd channel’s Pan Control functions as a left/right balance control for the matrixed
MS signal.
• The even channel’s Fader Control and Pan Control are disabled.
• The limiters of both inputs are linked.
• The background label of both inputs is connected on the Main Screen.
Linked
Unlinked
M/S Matrixing
When input pairs are linked MS, the odd channel is used for the Mid signal and the even channel is
used for the Side signal. To produce a stereo signal from an M/S configuration, the signal from both
microphones must be processed.
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
Input Setup & Control
connects to the odd Input, and the bidirectional microphone is the “side” signal and connects to even
Input. 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 configuration.
Mid Signal
Side Signal
Digital Inputs
The 664 accepts AES3 (AES/EBU) balanced, AES42 (Mode 1) balanced, and AES3id unbalanced digital signals on the Input 1 and Input 6 XLR-3F connectors. The 664 auto-detects between AES3 and
AES3id digital signals and adjust accordingly. Digital input gain is controlled from the front panel
faders.
Never attach unbalanced connections to an input set for AES42. This can result in damage to the hardware.
To use a digital input, slide the Input 1 or Input 6 Input Selector Switch to the right to enter the Input
Settings Screen. Press the Headphone Encoder to display the list of available input sources. Turn
the Headphone Encoder to select AES3 or AES42, and press the Headphone Encoder to confirm the
selection.

The 664’s digital inputs are sample rate converted to the internal recorder’s sample rate. To sync the
sample rate of the 664’s internal recorder to external digital audio devices, see Sampling Rate.
Things to consider when using AES digital inputs:
• When using an unbalanced AES3 (SPDIF) input, the other available digital input should not be
used with an AES42 microphone.
• Signal from digital inputs is not available on direct outputs.
12 Channel Mode
Direct outputs 1 to 6 can be used as line inputs in 12 Channel Mode. When Setup Menu option
INPUTS > Input Mode is set to 12 Channel, direct outputs 1 to 6 are changed to line inputs 7 to 12,
respectively. Each input is routed to its own ISO track and can be recorded. Each 7-12 input can be
switched to be a direct output for its respective 1-6 input.
When switching to 12 Channel Mode, Meter Views are not changed automatically, so inputs 7-12
may not be visible on any Meter View (See Meter Views). To automatically switch Meter Views while
switching between 6 Channel and 12 Channel Mode, it is recommended to save custom Setup Files
with the desired Input Mode and Meter Views. See Storing and Recalling Settings
The function of the Input Selector switches is altered in 12 Channel Mode: Slide the switch to the
right to PFL and access the Input Settings screen for inputs 7-12, and slide the Input Selector switch
left to PFL and access the Input Settings screen for inputs 1-6. The Input Settings screen for inputs
7-12 is slightly different than the Input Settings screens for inputs 1-6. HPF, Trim, and Fader values
are adjusted using the Select Encoder:

Limiters
Limiters prevent clipping by attenuating signals that surpass a set threshold. The amount of attenuation is defined by the “ratio” of the limiter and expressed as two numbers. All 664 limiters use a 20:1
compression ratio. This means that signal that exceeds the threshold by 20 dB will exit the limiting
stage at only 1 dB above the threshold.
The time it takes for limiting to begin once signal has exceeded the threshold is referred to as the “attack time” and the time it takes for limiting to cease once signal has fallen back below the threshold
is referred to as “release time”. Signals that exceed the threshold faster than the limiter’s attack time
can still cause clipping. The 664 limiters have a 1 ms attack time and a 500 ms release time.
The limiters are globally activated when the Setup Menu item LIMITERS > Limiters is set to On. This
activates both the input limiters (Inputs 1 through 6) and all output limiters. Sound Devices recommends using the limiters at all times. Limiters are present on both mic and line-level inputs as well
as the Master L,R tracks and the X1,X2 tracks. The 664 input limiters have a threshold of +16 dBu (4
dB below clipping), while the limiters for the L, R, X1, and X2 tracks are adjustable from the Setup
Menu item OUTPUTS > L,R Limiter Thresh and OUTPUTS > X1,X2 Limiter Thresh.
In normal operation, with a properly set gain structure, the threshold of the Input Limiter is rarely
reached. Without Input Limiters, high signal conditions can overload a channel and cause distortion. The Input limiter is working when the respective input’s Input Activity LED illuminates yellow.
If the Activity LED is regularly in the yellow, reduce the amount of gain applied to the channel by
turning down the Trim control. See Input Activity LED for additional information.
When Inputs are linked as a stereo pair, the Input Limiters are also linked and perform the same gain
reduction equally to both inputs.
The Output Limiters prevent the L,R and X1,X2 signal from exceeding the user-set limiter threshold.
Setup Menu options LIMITERS > L,R Limiter Thresh and LIMITERS > X1,X2 Limiter Thresh allow
limiter thresholds to be set in 1 dB increments from +4 dBu to +20 dBu.

Metering
Input, Track, and RTN levels are displayed in the various Meter Views on the Main Screen (see Meter
Views). Each segment of the meter represents 1 dB. A larger red square under the 20 dBU marker
indicates clipping on the track. A large yellow square indicates limiting activity on the track.
Meters can be displayed with segments or solid lines (Setup Menu option

Meter Ballistics
Audio meter “ballistics” is the manner in which a visual meter responds to audio signal levels. The
ballistics of all 664 meters is set globally from Setup Menu option SYSTEM > Meter Ballistics.
VU
VU (volume units) meter ballistics correspond closely to how the human ear perceives loudness.
This 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 mS. VU meters provide good visual indication of how loud a signal
will be, but provide poor information of actual signal peaks.
Peak + VU
The 664 can simultaneously display VU and Peak level information. In this mode the perceived loudness (VU) is displayed as a standard bar, and the Peak signal as a single, independent segment above
the VU.
Peak Only
16
Peak-reading ballistics (PPM) correspond to actual signal peaks, but don’t necessarily correspond
to perceived signal loudness. Peak meters have an instantaneous attack and a slow decay to allow
visual monitoring of peak activity. Peak metering is useful when interconnecting to audio inputs on
digital equipment. In the digital realm, signal overload can cause immediate distortion.
v. 2.02 Features and specifications are subject to change. Visit www.sounddevices.com for the latest documentation.

664 User Guide and Technical Information
Peak Hold
When Peak Metering is enabled (Peak Only or Peak + VU), peak hold displays the last highest peak value on the meter as a separate, individual meter segment. By default this meter
segment will remain visible for 1 second. This time can be adjusted from Setup Menu option
SYSTEM > Meter Peak Hold Time to 1, 2, 3, 4, or 5 seconds. The Infinity option will display the last
highest peak indefinitely until a higher peak is reached. The Off option will disable peak hold.
Input Activity LED
Each Input has its own Input Activity LED located just above the Input Fader.
The LED illuminates in various colors and intensities to represent the signal
level appearing at its respective input. Green = pre-fade signal activity, yellow
= pre- and post-fader limiter activity, red = pre- and post-fader signal overload
(peaking). Reduce the trim level control if the LEDs continuously illuminate
yellow or red. The Input Activity LED will ash yellow when the Input PFL is
latched. see PFL.
Headphone Peak LED
The Headphone Peak LED is located just left of the Headphone Encoder.
This LED will illuminate red to indicate clipping in the headphone amplier.
Monitoring without a visual indication of headphone clipping can mislead the
sound mixer into thinking that the output or return feeds are distorted.

Output Setup and Control
The 664 features a host of analog and digital outputs to accommodate for complex, multi-camera
setups. The 664 has 2 stereo output busses: The Master Bus (LR), and the Aux Bus (X1/X2).
Master and Aux Outputs
There are 4 pairs of balanced analog output connections for the Master Bus (XLR-3M, TA3, and 2
Hirose 10-pin), and one pair of balanced analog output for the Aux Bus (TA3). Additionally, there are
two stereo unbalanced outputs for the Master Bus (TA3 and 3.5mm Tape Outputs).
The XLR-3M and both Hirose 10-pin outputs are transformer-balanced, each driven from their
own transformer windings for excellent isolation. Each output can be independently set to Line
(+4 dBu nominal), -10, or Mic level (40 dB of attenuation versus Line) from the Setup Menu section
OUTPUTS. The master outputs are capable of driving long cable runs.
XLR-3M
Output Setup & Control
By default the XLR-3M outputs send a balanced analog signal. These connections can be independently configured to send AES3 signal. see AES Digital Outputs for details. When set to analog output,
the L and R XLR-3M connections always carry the Left and Right Master Bus program.
TA3 (Master L, R, X1, and X2)
The TA3 outputs send a balanced analog signal. The X1 and X2 TA3 connections always carry X1
and X2 Aux bus program. The L and R TA3 connections always carry the Left and Right Master Bus
program.
Hirose 10-pin
Each Hirose 10-pin connection has a balanced pair of outputs that carry the Left and Right Master
bus program. By default, each of the balanced outputs on the Hirose 10-pin connections sends a balanced analog signal. Each of the balanced outputs on the 10-pin A connections can be independently
configured to send AES3 signal. see AES Digital Outputs for details.
Each Hirose 10-pin also includes an unbalanced stereo return input for headphone monitoring. The
Sound Devices XL-10 Breakout Cable is an available accessory that provides easy access to the balanced outputs and stereo returns of the 10-pin Hirose connections.
Direct Outputs
Inputs 1-6 have corresponding direct outputs on balanced TA3 connections. By default, these
outputs are pre-fade and line level. The direct outputs can be set to post-fade from the Setup Menu item OUTPUTS > Direct Out Pre/Post. The direct outputs can be set to Line (+4
dBu nominal), -10, or Mic level (40 dB of attenuation versus Line) from the Setup Menu item
OUTPUTS > Direct Out Levels.
22
AES digital input signals are not available on direct outputs.
Tape Output
The 664 includes two unbalanced tape level outputs, a TA3 connector and a 3.5 mm jack. These two
connectors are resistively in parallel and are isolated from the balanced outputs.
v. 2.02 Features and specifications are subject to change. Visit www.sounddevices.com for the latest documentation.
Page 29
664 User Guide and Technical Information
Tape Outputs, by default, send the Left and Right stereo program. The Tape outputs can be used to
send the incoming RTN A, RTN B, or RTN C signals directly to receiving devices from Setup Menu
option OUTPUTS > Tape Out Source. This is useful for sending an IFB wireless feed of the RTN
audio to the producer for video playback.
Master and Aux Bus Level

Page 35
664 User Guide and Technical Information
The sampling rate of the digital recorder is set from Setup Menu item RECORDER > Sample Freq. See
Time Code section for details of “F” modes. The current Sample Rate is displayed on the Main Screen.
Word Clock Synchronization
By default the 664 recorder uses its own internal clock to generate its sampling rate. The BNC Word
Clock input and Word Clock output on the rear of the 664 can be used to clock the 664 from an external word clock signal or to synchronize external audio devices to the 664’s word clock.
To synchronize the 664 to an external word clock signal, connect the word clock signal to the
Word Clock Input BNC on the rear of the 664 and change TIMECODE/SYNC > Sync Reference to
Word Clock.
When the 664 is locked to external word clock, it is indicated on the Main Screen:
When Setup Menu item TIMECODE/SYNC > Sync Reference is set to Word Clock, but no valid ex-
ternal word clock is present, it will be indicated on the Main Screen:
The 664 only accepts word clock signals between 44.1 kHz and 48.048 kHz.
Bit Depth
When recording WAV files, the 664 records either 16 or 24 bit files. Bit depth is selected from the
Setup Menu item RECORDER > Bit Depth.
Bit Depth and Dynamic Range
Bit depth defines the digital “word length” used to represent a given sample and correlates to the
maximum dynamic range that is represented by the digital signal. Larger bit depths accommodate
more dynamic range. Sound Devices recommends 24-bit recording for all critical production.
Recording Media
The 664 records to approved removable CompactFlash (CF) and SD/SDHC/SDXC (SD) cards. The
664 can write to one or both of these cards at the same time. Visit www.sounddevices.com/approved for
an up-to-date list of tested and approved cards.
The SD card is inserted with the bottom of the card (the side with metal contacts visible) facing
toward the rear of the 664. Press until it clicks. To remove, push in again to release the spring-loaded
connector, then pull the SD card out.
The CF card is inserted with the top of the card (the side with the manufacturer’s branding label)
facing the rear of the 664. The final few millimeters of insertion require light force. To remove the CF
card, grip it firmly and pull it out.
Digital Audio Recorder
If the CF card is oriented correctly, it will slide in easily until only a few millimeters are protruding. If the
CF card is oriented incorrectly, it will slide in easily until over 1 cm of the card is still protruding.

664 User Guide and Technical Information
Formatting Media
The 664 uses the FAT32 file system for CF cards and SD cards under 32 GB in capacity. SD cards with
a capacity greater than 32GB are formatted with the exFAT file system. FAT32 and exFAT are compatible with all major operating systems. Before recording to CF or SD media, cards must be formatted.
To format cards in the 664:
1. Press the Menu buon to enter the Setup Menu.
2. Turn the Headphone Encoder to highlight FILE STORAGE, then press the Headphone Encod-
er to enter the FILE STORAGE section.
3. Turn the Headphone Encoder to highlight Erase/Format CF or Erase/Format SD, then Press
the Headphone Encoder to begin the formaing process.
The exFAT file system is not compatible with Windows XP or Mac OS X 10.6.4 or lower.
Time Code
The 664 holds accurate time code for up two hours between battery changes using its internal, Li-Ion
Digital Audio Recorder
time code battery. After two hours without power, the 664 reverts to a slightly less-precise time-ofday crystal to maintain the date/time of the unit. This time code battery is charged whenever the 664
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 time code and frame rate stamp in the BEXT and iXML chunks of an
AES31 (Broadcast WAV) file. During playback, the 664 generates SMPTE time code from this number
and extrapolates it based on the time code frame rate.
All files generated by the 664 have time code numbers that begin on the 0 frame (or 02 in DF modes)
and end on the 0 frame such that a file’s duration is always an integer number of seconds long. If
necessary, pre-roll and post-roll is dynamically applied to accomplish this. This simplifies synchronization in post-production.
Sound Devices Wave Agent Beta for Mac OS and Windows computers allows users to add or edit Beginning Time Code Stamps. See Wave Agent for more details.
The time code value and frame rate of the 664 are displayed on the Main Screen.

Time code modes
The time code mode determines if the 664 generates or reads time code and when
time code runs and stops. Time code mode is changed from the Setup Menu option
TIMECODE/SYNC > Time code Mode.
Rec Run (Record Run)
Generator mode. The 664 sends running time code while recording and stationary time code while
not recording. Time code in this mode defaults to the last stationary value at power-up. When
switching to Record Run from another mode, the internal generator will stop at the last number generated. A user-defined value can be jammed into the internal generator from the Setup Menu option
TIMECODE/SYNC > Set Generator TC.
Free Run
Generator mode. Time code runs continuously. The value can be set by “jamming value” in the Setup
Menu option TIMECODE/SYNC > Jam Menu or by manually setting a value from the Setup Menu
option TIMECODE/SYNC > Set Generator TC.
Free Run Auto Mute
Functions the same as Free Run mode except timecode signal is muted from the LEMO output when
the 664 is in stopped mode. This allows rec-run functionality when Rec Run mode is not suitable
(e.g. Multi-camera shoots). Note that timecode signal is still output during play and play-pause
modes.
24h Run (24 hour Run)
Generator mode. Time code runs continuously. When this Time Code Mode is selected or when
the time/date is altered, the time code value is jammed to the value of the time-of-day clock. The
value can be set by “jamming value” in the Setup Menu option TIMECODE/SYNC > Jam Menu or by
manually setting a value from the Setup Menu option TIMECODE/SYNC > Set Generator TC.
24h Run Auto Mute
Functions the same as 24h Run mode except timecode signal is muted from the LEMO output when
the 664 is in stopped mode. This allows rec-run functionality when Rec Run mode is not suitable
(e.g. Multi-camera shoots). Note that timecode signal is still output during play and play-pause
modes.
Ext-TC (External Time Code)
Reader mode. 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 stops as well. Recording
is triggered manually with the Transport Control.
Digital Audio Recorder
Ext-TC Auto-Rec (External Time Code Auto-Record)
Reader mode. The internal time code generator follows an external time code signal appearing at the

664 User Guide and Technical Information
Ext-TC/Cont (External Time Code Continuous)
Reader mode. 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. Recording is triggered manually with the Transport Control.
Ext-TC Auto-Rec/Cont (External Time Code Auto-Record Continuous)
Reader mode. 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

sensed. When stopped time code is sensed, recording stops.
Time code Frame Rate
The frame rate of the time code generator is set with the Setup Menu option
TIMECODE/SYNC > Frame Rate. When using an external time code mode, ensure that the 664’s
frame rate is equal to (or cross-jam compatible) the external frame rate.

664 User Guide and Technical Information
Time code Hold Off
Some devices that send rec-run time code will sometimes have a tendency to send short burst of
running time code. When using time code to trigger recording on the 664 (External time code autorecord modes) this behavior can result in unintentional recordings on the 664. To eliminate this
problem, the 664 features a Time code Hold Off function.
When using external time code auto-record modes, the 664 will wait (“hold off”) for the amount of
time specified in Setup Menu option TIMECODE/SYNC > Hold Off before beginning recording. Running time code lasting less than the Time code Hold Off value will not trigger a recording on the 664.
Things to consider when using Time code Hold Off:
• This feature only applies in Ext-TC Auto-Rec and Ext-TC Auto-Rec/Cont.
• If Pre-Roll is set, it will be applied (see Pre-Roll). Pre-Roll will only capture audio from the initial
detection of a time code signal. If no Pre-Roll is selected, the le will begin after the Hold O time
expires. It is best practice to set Pre-Roll, in the Setup Menu option RECORDER > Pre-Roll Time,
to a value greater than the selected Time code Hold O value. This ensures that audio is captured
from the moment a time code signal is detected and that unintentional les triggered by short
bursts of time code are not generated.
F Sampling Rate Modes
48.048k and 48.048kF
The 48.048kF mode (F stands for fake, faux, Fostex—take your pick) is a specific 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 files written at 48.048 kHz. In this mode files 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 film (24 fps-to-NTSC) in non-linear edit systems, such as Avid or Final Cut Pro. Since
the file is stamped as a 48 kHz file, 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.
Digital Audio Recorder
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.
33
Page 40
664 User Guide and Technical Information
The audio file, however, is stamped with a 29.97 ND frame rate, along the 48 kHz sampling rate. It
will appear as if the file was originally recorded at a 48 kHz sampling rate at a TC rate of 29.97 ND.
Fostex DV40
When using files recorded in the 48.048kF mode 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, identifies the file 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 file
is identified as 24ND or it can be set to 29.97ND while the file is identified as 30ND. By default, when
47.952kF mode is selected the frame rate is changed to 29.97ND and identified as 30ND unless the
Frame Rate was already set to 23.97 in which case it will remain at 23.97.
Pre-Roll
To prevent missing record cues or up-cutting takes, the 664 has pre-roll buffering available. When
active, pre-roll begins recording at a set number of seconds preceding the record button being
Digital Audio Recorder
pressed. The Pre-Roll time can be adjusted from the Setup Menu option RECORDER > Pre-Roll Time.
Maximum pre-roll time is 3 seconds when recording mono WAV files to any media. In all other cases,
maximum pre-roll time is 6 seconds.
Pre-Roll is disabled when the time code mode is set to Record Run,
External Time Code Auto Record, or External Time Code Continuous Auto Record. This prevents
possible overlapping time code numbers between adjacent files.
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
664 uses rock-stable word clock and PLL circuitry to generate its internal clock frequency.
The 664 can act as either a clock master (Setup Menu option TIMECODE/SYNC > Sync Reference
set to Internal), where it is the provider of word clock, or as clock slave (Setup Menu option
TIMECODE/SYNC > Sync Reference set to Word Clock), where it locks its internal word clock to a
received external master reference clock. External word clock signal is provided via the Word Clock
input BNC on the Rear Panel.
When accepting digital input signal, the 664 always converts the sample rate to the recorder’s
sample rate. During playback, the 664 only uses its own word clock, ignoring external word clock.
File Management
The 664 writes files to both CompactFlash (CF) and Secure Digital (SD) storage media. Storage media must be formatted prior to use with the 664. CF and SD storage media inserted
into the 664 can be formatted with Setup Menu option FILE STORAGE > Erase/Format CF and
FILE STORAGE > Erase/Format SD respectively. The 664 formats CF cards of any capacity and SD
cards of 16 GB or less with the FAT32 file system. SD cards with a capacity greater than 32 GB are formatted with the exFAT file system. To manage files on 664 media using a computer, simply remove
the media from the 664 and insert into a compliant CF or SD card reader connected to a computer.

The 664 writes AES-31 Broadcast Wave formatted files. The audio files created by the 664 include
additional information (Metadata) in the file’s header, BEXT (Broadcast Audio Extension) and iXML
data chunks. See Metadata section of Specifications. Software that does not recognize these additional
broadcast wave data chunks will simply ignore them.
MP3
MPEG-1 Layer III is a lossy compression algorithm, often used for music and transcription recording
purposes. The 664 records two-channel MP3 audio files with data rates of 320 kb/s, 192 kb/s, or 128
kb/s.
File Structure
The 664 records polyphonic or monophonic audio files. A polyphonic take consists of one file with
multiple tracks, whereas a monophonic take consists of one file for each track, per take.
A polyphonic take and file name consists of a scene name, take number, and a file extension. For
example, for scene S01, take T01, the polyphonic file name and take name are both S01T01.wav.
S01T01.WAV

All files generated by the 664 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 STORAGE > FOLDER OPTIONS. Folder choices include TOP-LEVEL,
MID-LEVEL, and BOTTOM LEVEL FOLDERS. Folders are created when the record key is pressed.
This reduces the likelihood of empty folders.
Each folder resides in the folder one level below it. If the folder one level below the target folder is
set to <None>, the target folder will reside in the next level folder that is set to something other than
<None>.
Each folder level has a corresponding list of available names that can be edited manually by the user.
To add an entry to the list of folder names of any folder level:
1. Access Setup Menu option FILE STORAGE > FOLDER OPTIONS
2. Select desired folder level and press the Headphone Encoder.
3. Rotate the headphone Encoder to select <Add New Entry> then press the Headphone Encod-
er. Use the on-screen keyboard to compose a name for the folder.
4. Slide the RTN Switch right to create the folder name and select it for this folder level.

the date. Whenever a new day occurs, the 664 will prompt asking if the user would like to create a
new daily folder. With an example date of August 20th, 2012, the naming format of the daily folder
would be: 12Y08M20. The name of the Mid-Level folder will also be stored in the TAPE field of the
iXML and bEXT chunks of all subsequently recorded WAV files.
Bottom-Level folder. The Bottom-Level folder can be named manually, by scene name, or set to
<None>. When set to <Scene>, a new folder will be created each time the scene name is changed.
Automatic File Splitting
During recording, the 664 will split a take that exceeds 4 GB into multiple files. The split is sampleaccurate, so files joined together in post-production will be seamless. The maximum file size that the
664 creates can be adjusted from the Setup Menu option FILE STORAGE > File Max Size. The follow-
ing file size options are available:
• 4GB

Mixer Linking
Linking the 664 With Another 664 or 552 Mixer
The Link I/O function allows the 664 or 552 to be interconnected with another 664 or 552 mixer for
applications requiring more inputs. When the 664 is linked with a 664 or 552, all inputs appear at
both mixer’s outputs. The stereo mix from the other mixer will be routed to the 664’s stereo Master
Bus and recorded on tracks L and R. Return audio and PFL occur on the headphone output of both
mixers. The Link I/O connector is an unbalanced TA5M wired pin-1 = HP L, pin-2 = HP R, pin-3 =
Mix R, pin-4 = Mix L, pin-5 = link detection/ground.
To Link the 664 to another 664 or 552 mixer:
1. Connect the Link I/O of the 664 to the Link I/O of the other 664 or 552 mixer using a TA5F

and PFL only occur on the headphone output of the mixer that it is performed on. The 552 Link I/O
connector is an unbalanced TA5M wired pin-1 = HP L, pin-2 = HP R, pin-3 = Mix R, pin-4 = Mix L,
pin-5 = Link detection/ground.
Linking to a 302 or 442
The Tape Out/Mix Out of a 302 is an unbalanced stereo TA3F connector. The 442 has two Tape Out/
Mix Out connectors, 3.5 mm and TA3. For the most secure connection use the TA3 Tape Out/Mix
Out connector. The TA3 on the 442 and 302 is wired pin-1 = ground, pin-2 = Left, pin-3 = Right. For
details on the 3.5 mm connection see Linking to a MixPre.
Sound Devices XL-TA35 is a 12-inch, TA5F to TA3F accessory cable used to link Sound Devices 302
and 442 mixers to the 664 or 552. For more details see Accessories.

664 User Guide and Technical Information
Powering
The 664 is powered by external DC power or internal AA baeries (NiMH or
Lithium chemistries preferred. see Internal Baery Powering). The power switch
selects the power source, either internal or external. There is a large enough
power reserve to switch back and forth from one source to the other without
interrupting mixer operation.
External Powering
The 664 can be powered from any DC voltage from 10 to 18 VDC. Pin-4 of the locking, Hirose connector is positive (+) and pin-1 is negative (–). The external DC supply is fully isolated (floating)
from the rest of the mixer for easy and safe interconnection with other external audio gear.
Internal Battery Powering
Internal batteries can be used as a back-up in the event that external power is removed or depleted.
The 664 uses five AA-sized (LR6) batteries. The 664 can use NiMH, 1.5V Lithium, or Alkaline AA batteries. Run time will be very limited when using Alkaline batteries (30 minutes to 1 hour, depend-
ing on settings). NiMH or Lithium batteries are the preferred type because of the approximate 2x
to 4x run time compared to Alkaline batteries.
Voltage Metering
The Main Screen displays a DC Voltage Indicator in the form of a battery icon that indicates the level
of the power source currently in use (internal or external). When the battery icon is filled green, the
voltage of the active power source (internal or external) is full. The green color will move down
as voltage depletes, changing to red and flashing when the Warning Voltage Threshold is reached.
When the voltage is critically low, the entire battery icon will become red and flash.
Maximum Voltage Minimum Voltage
A numeric reading of the internal and external voltage levels is displayed in the Setup Menu main
level at all times. Internal voltage is displayed on the left side and external voltage is displayed on
the right side (This example shows a 664 powered from a 12.0V external power supply with no AA
batteries inserted):
The voltage range of the DC Voltage Indicator and the Warning Voltage Threshold can be adjusted.
These values are adjusted with the Setup Menu option SYSTEM > Ext DC Ref. Adjust the Ext DC
Reference to match the type of battery being used to power the 664 externally. The voltage range and
Warning Voltage Threshold for each setting are shown in the following table.
Powering
47
Page 54
664 User Guide and Technical Information
Setting Low Voltage Warning Voltage High Voltage
12V Ext DC 9 10 11
NiMH 11 11.5 13
Expanded NiMH 11 11.5 18
12V Lead Acid 10 11.4 14
14V Li-ion 12.5 13.5 16.3
Full Range 6 11.5 18
When the voltage of the external power supply drops below the Low Voltage Threshold, the 664 will
react differently depending on the state of the internal recorder:
• During recording or playback, the 664 will automatically switch to internal baeries, if available.
• If the internal recorder is idle (Not playing back or recording), the 664 will power down.
During media operations (read or write) the 664 will utilize the main (external) power source if available.
This will be reflected on the DC Voltage Indicator.
Power Consumption
Powering
The 664 varies in the amount of current it draws. Several features of the 664 directly affect current
draw in different ways. The following list highlights the larger current drawing functions.
1. Microphone powering - the main source of extra 664 current draw. See Phantom Power. 48
V Phantom can draw copious amounts of current depending on what model microphone
is used. Two identical phantom powered microphones draw twice as much current as one.
Microphones vary widely in their current draw depending on type and phantom voltage applied.
2. Audio Recorder - the recorder, whether in record or playback, increases power consumption.
3. Digital Outputs - disable digital outputs in the Setup Menu when they are not needed since
they draw additional current.
4. Output drive level - higher output drive levels into multiple, low-impedance inputs increases
power consumption.
5. Headphone output circuit - high headphone output levels increase current draw.
6. LED and LCD Brightness - decrease LED and LCD brightness to extend baery runtime.
