552 User Guide and Technical Information
Welcome
Thank you for purchasing the 552 Mixer. It is the next evolutionary step in professional, portable
audio mixers. With a core design based on the legendary 442, it contains countless improvements
and added flexibility.
Developed with insight from the industry’s top audio engineers, the 552 Field Mixer encompasses
the audio performance, feature set, and mechanical construction demanded by those who rely on
audio gear for their livelihood. The 552 contains five high-performance microphone preamplifiers,
multiple outputs including AES outputs, comprehensive monitoring, and a high-quality built-in
audio recorder. Its input and output flexibility, including pre- or post- fade direct outputs on each
channel, make the 552 at home in small “run-and-gun” applications as well as large, multiple input
productions.
The 552 incorporates a complete feature-set into a compact, functional design. 552 features are accessible from the three main surfaces. The Setup Menu can be accessed at anytime to make changes
to various parameters. The highly efficient circuitry allows the mixer to be powered by either four
internal AA batteries or external 10-18 VDC.
With a two-track recorder on-board, sound mixers can rest assured that audio is being recorded locally. The 552 records polyphonic Broadcast Wave or MP3 files to removable, Secure Digital (SD) or
Secure Digital High Capacity (SDHC) cards.
The 552, like all Sound Devices professional audio products, is designed to withstand the physical
and environmental extremes inherent to field production. Its compact construction strikes the perfect
balance between performance, accessible controls, and durability.

Input Setup and Control
The 552’s inputs consist of five, full-featured preamplifiers. Each input has a wide gain range to accommodate nearly all signal types of microphone and line. The 552 easily accepts signals from lowsensitivity ribbon and dynamic microphones, medium-level wireless and condenser mic outputs,
and “hot” line-level signals.
The XLR inputs of the 552 are transformer-balanced. The isolation characteristics of transformers are
superior to other balancing techniques and are ideal for the hostile and uncontrolled environments
of field production. Transformers provide galvanic isolation from the driving source, meaning there
is no direct electrical connection. Signals are “transformed” magnetically. The input transformers in
the 552 use premium magnetic core material to achieve high signal-handling-capability (especially at
low frequencies) while keeping distortion to a minimum. Because of their inherently-high common
mode impedance, transformers are unrivaled by any other type of input for common-mode noise
rejection.
The inputs of the 552 can be used as balanced or unbalanced. To unbalance, tie pin-3 to pin-1 of the
XLR connector. There is no change in gain between unbalanced and balanced connections into the
552.
Mic/Line Selection
Two input modes are available, Mic and Line . When Line is selected the LINE LED is illuminated.
Taking into account all gain stages, the 552 has 93 dB of available gain from Mic input to Line output.
When inputs are set to the LINE position, the input sensitivity is reduced by 40 dB.
The selected channel is set to receive a line level input when the Line LED adjacent to the input’s PFL
is illuminated. To toggle between Mic/Line levels, hold the respective input’s PFL and then slide the
Slate Mic/Line switch to the Slate position.

552 User Guide and Technical Information
1) Hold the Input’s PFL.
2) Slide the SLATE MIC/TONE switch left.
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 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 in the Setup Menu. The selected voltage
level applies to all inputs with phantom power enabled. Phantom power voltage is 48V at factory
default. See Setup Menu.
Phantom power can be activated individually for each input. To enable or disable phantom power, press and hold the respective input’s PFL switch then momentarily slide the Slate Mic/Tone
switch to the Tone position. The respective input’s PH LED illuminates when phantom is enabled.
1) Hold the Input’s PFL.
2) Slide the SLATE MIC/TONE switch right.
Phantom power is only applied to inputs set for Mic level at factory default. Phantom Power can be
applied to inputs set to Line- and Mic-Level in the Setup Menu. This is useful when using microphones in high SPL environments.
Make certain to disable phantom power with Line-level output devices that are susceptible to damage
from DC.
The 552 can provide up to 10 mA to each input at 48 V, sufficient for the most power-hungry condenser microphones. Many phantom powered microphones do not require 48 V and can be properly
powered with 12 V. When acceptable, use 12 V phantom to extend the 552’s battery life.
If Phantom Power is not required, for instance with dynamic microphones, it is best practice to disable it. Phantom power can capacitively couple noise into the mic inputs with poor mic cables. When
15
552 User Guide and Technical Information
disabled, no voltage is applied to the microphone input. Do not apply power to ribbon microphones,
improperly wired cables can permanently damage the microphone.
Gain - Trim and Fader Relationship
The gain of an input is adjusted by two controls, Input Trim and Input Fader. This two-stage architecture is identical the to topology of mixing consoles and provides a great deal of flexibility. Input
Trim is often thought of as a course gain control and the Input Fader as the fine gain control.
Input Trim
The 552’s input sensitivity is set with the pop-up knob Trim control. 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, recess the Trim control to hide it from the 552’s mixing surface. Trim
level is adjustable from 22 to 72 dB of gain.
Input Fader
The Input Fader is the primary control used during mixing operation. Use the Input Fader to make
fine gain adjustments during operation. The fader can be attenuated from off (full counter-clockwise
position) to +15 dB above the set Trim level (full clockwise position). To optimize gain structure for
the best noise performance operate input faders at or near the 0 dB (unity gain) position.
High-Pass Filter
Each input channel has an adjustable high-pass filter controlled by the High-Pass Filter pop-up knob.
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 552’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. See Specifications. 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.
When engaged or disengaged, the high-pass filter gradually fades into the selected state. This prevents sudden obvious pops in the audio.
The 552’s high-pass filter circuit is unique because of its placement before any electronic amplification. Most mixer’s high-pass filter circuits are placed after the microphone preamplifier, such that all
of the low-frequency signals get amplified. By virtue of the 552’s circuit cutting the low-frequency
signals before amplification, higher headroom is achieved in the presence of signals with significant
low-frequency energy.

Features and specifications are subject to change. Visit www.sounddevices.com for the latest documentation.
552 User Guide and Technical Information
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 552 in conjunction with the microphone’s filter to increase the filter’s
slope.
The filter can be removed from the circuit completely by moving 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 knob control routes inputs to the left and right output buses. For most applications, a
channel will be panned either hard-left, hard-right, or center. The pan pot has a detent in the center
position. After setting the pan, the pan control can be recessed to hide it from the mixing surface during normal operation.
Remove From Mix
An input, or pair of inputs, can be removed from the master Left/Right outputs. This allows the user
to isolate an input or a pair of inputs while still having full control of the input’s fader. This is useful
when an input is used as communication link between the boom op and the sound mixer. It is also
useful for isolating a pair of inputs from the stereo bus and route their post-fade direct outputs to a
separate recorder or AES3 outputs. The following options are available in the Setup Menu function
Remove From Mix (-4 LED):
• None (all inputs appear at outputs)
• Inputs 3 and 4
• Input 1
• Input 5
• Inputs 1 and 2
Input Polarity
The polarity (sometimes referred to as a phase inversion) of inputs 2 and 4 can be reversed. 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 MS microphones.
To toggle between normal and reverse polarity, activate the respective input’s PFL then press the
Battery Check Button. When the front panel Input Polarity LED is lit, the polarity is reversed on that
channel.
1. Hold the Input’s PFL.
2. Press the Battery Check Button.

552 User Guide and Technical Information
Stereo Linking
The Stereo Link feature allows two pairs of 552 inputs to be linked as stereo pairs. These are inputs
1,2 and inputs 3,4. In the Setup Menu inputs can either be linked as either a Stereo Pair or an MS
Stereo Pair. Input Linking is indicated by the odd channel’s (1 and 3) LINK LED. When an input pair
is linked as an MS pair, both the Link and MS LEDs will be lit.
Stereo Pair Linking
When Stereo Linking, input channels 1 and 2 and/or channels 3 and 4 act as a single stereo pair, controlled by the odd channel’s Fader. The odd channel’s Pan control acts as the balance control between
left and right. The even channel’s Fader and Pan controls are not active when inputs are linked. The
Trim control and High-Pass Filters continue to act independently of each other. When linked, the
channel’s Input Limiters are also linked. When inputs are linked as a stereo pair the odd input’s Link
LED is illuminated.
MS Pair Linking
When Linking inputs as an MS pair, channels 1 and 2 and/or channels 3 and 4 are linked as an MS
pair. The odd input (1 and 3) is the Mid signal and the even input (2 and 4) is the Side signal. The
odd channel’s Pan Control functions as a left/right balance control for the matrixed MS signal. The
even channel’s Fader and Pan controls are disabled. Each channel’s Trim control and high-pass filter
continue to act independently of each other. Use channels 1 and 2’s Trim controls to vary the Mid
and Side levels respectively. When linked, the Input Limiters are also linked. When inputs are linked
as an MS pair the odd input’s Link and MS LEDs will illuminate blue.
Output Setup and Control
The 552 has stereo output bus that feeds multiple outputs. Additionally, each 552 input has its own
direct output. This output flexibility is essential for complex, multi-camera productions.
Master Gain Control
The Master Gain Control adjusts the overall output level of the left and right outputs. The gain range
of the Master Gain Control is from Off to +6 dB of gain. For most applications the Master control
should be set at the unity gain (0) position. The master gain is on a pop-up knob so it can be set and
hidden from the main surface. It is best practice to hide the Master Gain Control so that inadvertent
adjustments are avoided.
Master Outputs
The master outputs consist of three sets of connectors XLR, TA3, and Hirose 10-pin. The XLR and 10pin 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). The master outputs are capable of driving long cable runs.

552 User Guide and Technical Information
XLR
The XLR outputs are generally used as analog outputs but can be selected for AES3. At Factory
Default, the XLR Outputs are analog. Each XLR connector is configured in the Setup Menu to output
an AES3 digital signal. See AES Digital Outputs for details. When set as analog, the XLR labeled L will
output the Left program, XLR labled R will output the Right program. Each output can be set to
output at Line, -10, or Mic levels using the adjacent level switches.
TA3
The TA3 master outputs, located above the XLR Master Outputs, are an additional set of master
outputs. These outputs are active-balanced and can be used as either balanced or unbalanced. The
output level is set between Line, -10, and Mic levels from the Setup Menu. At Factory default, the
output level of the TA3 Master Outputs is Line Level.
Hirose 10-Pin
The 10-Pin outputs are used as either analog or digital outputs. At Factory Default, the 10-Pin Outputs are analog. Each output is configured in the Setup Menu to output an AES digital signal. See
AES Digital Outputs for details.
The Hirose 10-Pin connector contains balanced analog Left and Right outputs. The output level is
selectable between Mic, -10, and Line levels using the level switches located directly below the connector. The Hirose 10-Pin also includes an unbalanced stereo return (RTN A) 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 RTN A connection of the 10-pin Hirose connector. See RTN
and Connector Pin Assignments for details about the Hirose Multi-Pin connector.
Direct Outputs
Each input channel has its own balanced TA3 Direct Output connection. These outputs are used to
send the isolated channel’s audio to another destination. The Direct Output signal is menu-selectable
as either pre- or post-fader. When activated, the Slate Microphone and Tone Oscillator signals are
also sent to the Direct Outputs. The nominal output level is selectable in the Setup Menu as Mic, -10,
or Line level. See Setup Menu.
Tape Outputs
Tape Outputs are typically used to interface with consumer devices such as MiniDisc and compact
transcription recorders. The 552 includes two unbalanced tape level outputs, a TA3 connector and
19
552 User Guide and Technical Information
a 3.5 mm jack. These two connectors are resistively in parallel and are isolated from the balanced
outputs.
Tape Outputs, by default, send the Left and Right stereo program. Using the RTN Loopback function, the Tape outputs can be used to send the incoming RTN A or RTN B signals directly to receiving
devices. See RTN Loopback for more details.
Mono Mic Output
The Mono Mic Output is a summed mix of the left and right output channels. The 3.5 mm female
connector outputs a mono, mic-level signal intended for connection with portable transcription
recorders and wireless IFB transmitters.
Using the RTN Loopback function, the Mono Mic output can be used to send the incoming RTN A or
RTN B signals directly to receiving devices. See RTN Loopback for more details.
AES Digital Outputs
Each of the XLR or 10-pin Hirose outputs can be configured in the Setup Menu to output AES3
digital signals. The front panel AES Out LED is lit when one or both of the XLR or the 10-Pin outputs
are selected as digital outputs. The Left XLR or 10-pin output contains the two-channel AES A pair,
the Right XLR or 10-pin output contains the two-channel AES B pair. The selected output connector’s
Level Switch should be set to Line when using it as a Digital Output. In the Setup Menu, the following routings can be sent to each one of the AES pairs. Program before the comma appears on the
left-side of the AES Output and program after the comma appears on the right.
• Left Program, Right Program

Limiters
When the 552 Limiters are engaged, it is nearly impossible to clip (overload) the 552 mixer. Activate
the 552 limiters by setting the front-panel “LIM” switch to either LINK or ON. This enables both the
input and output limiters and determines the behavior of the output limiter. Sound Devices recommends that the limiters be active at all times.
The Input Limiters act solely as “safety” limiters. In normal operation, with a properly set gain
structure, the threshold of the Input Limiter will not be reached. In the event of extremely high input
signal levels, such as in high SPL environments, an Input Limiter will activate to prevent the input
signal from clipping. Without Input Limiters, high signal conditions can overload a channel and
cause distortion.
The Limiters do not alter signals below the threshold. When Inputs are linked as a stereo pair, the
Input Limiters are also linked and perform the same gain reduction equally across both inputs.
The Input limiter is active when the respective input’s Input Activity LED illuminates yellow. If the
Activity LED illuminates yellow substantially, reduce the amount of gain applied to the channel by
turning down the Trim control. See Input Activity LED for additional information.
The Output Limiters prevent the output signal from exceeding the user-set limiter threshold. In the
Setup Menu the Output Limiter Threshold can be set in 1 dB increments from +4 dBu to +20 dBu. See
Setup Menu At Factory Default, the mixer is set to limit the output signal peak levels to +20 dBu. This
assures that the output of the 552 will not overload inputs that accept full line-level signals.
The orange LIM LEDs, located at the end of the meter scale, illuminate in various intensities to represent output limiting.
LIM and LINK
The Output Limiters can either be linked as a stereo pair (LINK) or can work as two independent
limiters (LIM). When linked, the limiters will apply the same gain reduction equally to both the Left
and Right outputs. The LINK position is recommended when recording stereo program, so that level
changes are identical for both channels. The LIM position is recommended when using the 552 Outputs as two separate buses.

552 User Guide and Technical Information
Bit Depth
When recording WAV files, the 552 records either 16 or 24 bit files. 24-bit recording provides greater
dynamic range and addition headroom for signal peaks. Sound Devices recommends 24-bit recording for all critical production.
Bit Depth and Dynamic Range
Bit depth defines the digital “word length” used to represent a given sample. Bit depth correlates
to the maximum dynamic range that is 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 exponential measure (exponent of 2), so as bit depth increases, the amount of data it represents increases
exponentially. The majority of field 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.
Sampling Rate
The 552 records WAV files at the sampling rates selected below. The sampling frequency is set in the
Setup Menu.
• 44.1 kHz
• 88.2 kHz
• 48 kHz
• 96 kHz
Sound Devices recommends 48 kHz sampling for all 552 production applications. Sampling rate options are limited to 48 kHz and under when an MP3 or a Time Code to Track option is selected. If the
sampling rate is set to a higher rate when an MP3 option or a Time Code to Track option is selected,
the sampling rate defaults to 48 kHz.
Sampling Frequency and Audio Bandwidth
The sampling frequency is expressed in samples per second (hertz) and defines the number of times
in a second that an analog audio signal is measured. Sampling frequency determines the audio bandwidth, or frequency response, that can be represented by the digital signal. To roughly estimate the
maximum bandwidth available for recording divide the sampling frequency by two.
Recording Media
The 552 records to a removable Secure Digital High Capacity (SD or SDHC) media. SD cards compatible with the 552 require FAT32 formatting. To format media from the 552, press and hold the following buttons in order:

If the internal batteries drop to extremely low voltage levels while recording, the recorder will automatically close the file that it is recording to prevent it from being lost. The recorder is locked out
until the power source is switched to external or the 552 is powered down and batteries are changed.
Record Pause
When Record Pause is enabled in the Setup Menu, the recordings can be stopped then continued
without creating a new file. Record Pause is useful for reporter interviews or any application that can
benefit by stopping and starting recording without generating a new file. To use the Record Pause
feature:

9.
Press the REC key again to continue recording.
10. Press the STOP key twice to finalize the recording. At this point, the file is available for Playback and the
next press of the REC key begins recording the next incremented take.
Please note that the Record Pause behavior will vary depending on the set Time Code mode. When
Time Code is set to Stamp File or Stamp File Auto Record, the Record Pause feature is ignored. This
prevents the event of offsets in time code. Record Pause is available when Time Code is set to Replace Left and Replace Right. This allows linear time code to be recorded to one of the audio tracks.
When set to Auto Record Replace Left or Auto Record Replace Right, the 552 begins recording when
the time code signal advances. When time code becomes stationary, the 552 stops and closes the file.
If the recording is manually stopped by pressing the stop button the recording is paused. If time
code is stopped then started again the recording continues recording. Press Stop twice at anytime to
stop and close the file. See Time Code for details.
Time Code
The 552 stamps the metadata of recorded WAV and MP3 files according to the internal time and date
clock or according to incoming time code signals on the RTN B TA3 input connector. Time Code
Mode is off at factory default. When time code mode is off, the TC In LED remains off. External time
code is ignored and files are stamped according to the internal time and date clock at 30 frames per
second.

v. 1.1
Features and specifications are subject to change. Visit www.sounddevices.com for the latest documentation.
552 User Guide and Technical Information
When time code is set to any mode other than off, time code values are taken from the RTN B TA3
input connector when applicable. Time Code values are written to the file at the moment the record
key is pressed. This allows the Sound Mixer to sync the audio recorded by the 552 with the master
source. If there is not a valid time code signal detected, the 552 stamps files according to internal
time and date clock at 30 frames per second.
Incoming Time Code signals must be running prior to pressing record to ensure proper frame rate and
time stamps. Time Code stamping is only performed at the moment record is pressed. If the time code
source is not running at the moment record is pressed, the 552 will stamp the file according to the stationary time code that it is receiving. If no time code is present the 552 will use its default time of day stamp.
When Time Code is enabled, RTN B monitoring and functionality only apply to the 3.5 mm RTN B jack.
The TC In LED flashes blue when time code is set to on in the Setup Menu, but there is not a valid
time code signal connected to the RTN B TA3 input connector. The TC In LED illuminates solid blue
when time code is on and a valid external time code signal is detected.
Time Code to Track
The linear time code signal connected to the RTN B TA3 input connector is recorded when either the
Replace Left or Replace Right options are selected in the Time Code Setup Menu. The linear time
code signal overrides the selected side of the AES A Source sent to the Recorder.
Replace Left, Replace Right, Replace Left Auto Record, and Replace Right Auto Record modes are
only available with 44.1 and 48 kHz sampling rates. When the sampling rate is set to 88.2 or 96 kHz
and one of the Time Code to Track modes is selected the sampling rate is forced to 48 kHz.
The 552 prevents sending time code signals written to track to the outputs and the headphone monitor.
The REC SOURCE headphone monitor selection continues to monitor the AES A Source when a Time
Code to Track option is selected. Time Code recorded to Track is muted while playing back the file from the
552.
External Time Code Auto Record
The 552 can be set to automatically start and stop recordings according to the incoming time code
signal when anyone of the Auto Record modes is selected in the Time Code Setup Menu. The 552
enters record as the external time code advances, and the recording is stopped when the external
code is stationary. This is appropriate when dual-system sound is used with video cameras set for
Rec Run time code. The video camera functions as master time code and the 552 recorder “transport”
follows the video camera transport.
Playback
After a file has been recorded, the 552 can play back the file. The last file recorded is always the file
that is immediately available for playback. Playback audio is sent to the headphone monitor. The
Headphone Selector position determines the monitoring behavior. ST = Left and Right Stereo, M =
Left and Right Mono, L = Left Mono, R= Right Mono, MS ST = Mid Side Stereo Decoded, and REC
SOURCE = Left and Right Stereo. The LED meter display indicates headphone monitor activity.
To navigate among files for playback, press the rewind and fast forward keys while playback is
stopped. To navigate among daily folders, press and hold the Battery Check button and press
Rewind or Fast Forward to go to the previous or next day’s folder respectively. As a file or folder
is loaded a short beep is sent to the headphone monitor followed by the file number or day of the
folder.
27
552 User Guide and Technical Information
To playback a file, push the Record Controller down toward the Play position. To pause playback,
press the Record Controller. To Stop playback, press the Record Controller twice. To Rewind or Fast
Forward through a file, press and hold the Record Controller to the left or right respectively while
the file is playing back.
By default playback audio is only sent to the headphone monitor. To send the playback audio to the
Left and Right Outputs, press and hold Battery Check then press Play. After the file is stopped the
outputs will return to normal program.
Metering
The 552 features two large 21-segment LED output meters. The meters uses energy-efficient GaN
LEDs, which can be clearly seen in full sunlight. The 552 output meters are unaffected by shock, temperature, or humidity extremes. The microcontroller-based meters provides a selection of ballistics
and lighting intensities.
Meter Ballistics
The output meters display any of five types of meter ballistics: VU, Peak, Peak and Peak Hold, a
composite of VU and Peak, and a composite of Peak Hold and VU. Meter ballistics are set in the
Setup Menu. See the Setup Menu.
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 great visual indications of how loud a signal
will be. However, VU meters provide poor information of actual signal peaks.
In VU mode, the front panel meter labeling is in volume units. VU meters are always referenced to
an actual signal level in dBu, the 552 VU meter is referenced with 0 VU corresponding to 0 dBu at the
Line-Level outputs. If needed, the reference level can be changed in the Setup Menu to +4 or +8 dBu.
Peak
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 the
user to visually monitor peak activity. Peak metering is useful when interconnecting to audio inputs
on digital equipment. In the digital realm, signal overload can cause immediate distortion.
The peak meter’s front panel markings are calibrated in peak dBu level at the Line Level outputs.
Peak + Peak Hold
Peak-reading ballistics correspond to actual signal peaks, but the peak value is held in the meters for
two seconds. Peak Hold indicators are useful for metering in applications when an overload condition is unacceptable.
Peak + VU
The 552 can simultaneously display VU and Peak level information. In this mode the perceived loudness (VU) is displayed on a bar graph, and the Peak signal on a dot above the VU. With this combi-

552 User Guide and Technical Information
nation the user gets the best of both VU and Peak metering by seeing the “loudness” of the signal
while observing peaks at the same time.
Peak Hold + VU
This is the default meter ballistics setting, it is a combination of Peak + VU and Peak Hold. The meter
simultaneously displays the Peak and VU information while holding peak values for two seconds.
Zoom Metering
Zoom Mode allows the user to quickly display the output levels in 1 dB increments from 0 dBu to
+20 dBu. Each LED represents a 1 dB change. While in Zoom Metering mode, the etched -30 LED is
re-assigned to 0 dBu, the etched -24 is actually +1 dBu, and so on. Press the Headphone Controller to
enter and exit Zoom Metering Mode. The blue Zoom LED indicates that the meter is in Zoom Metering Mode. Zoom Metering Mode can be disabled in the Setup Menu Function Metering Ballistics to
prevent accidental activation.

Input Activity LED
Each channel has its own Input Activity LED located just above the Input Fader. The LED illuminate 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 postfader signal overload (peaking). Reduce the trim level control if the LEDs continuously illuminate
yellow or red. The Input Activity LED will illuminate yellow when the Input PFL is latched on.
Headphone Peak LED
Like the Channel Peak LEDs, the headphone circuit also has a peak overload indicator. This LED is
useful because headphones can often overload before overloading the 552’s stereo output bus. Monitoring without a visual indication of headphone clipping can mislead the sound mixer into thinking
that the output or return feeds are distorted.

552 User Guide and Technical Information
The left meter indicates the signal level of the soloed channel. PFL monitoring only affects the headphone monitor, it does not affect audio sent to the outputs. The selected input’s Activity LED illuminates yellow when the input’s PFL is latched on. PFL latching operation only allows for one input to
be soloed at a time. To PFL multiple inputs, use momentary operation.
RTN A and B
The Return monitor switch has two positions, A and B. When switched to the left or A position, RTN
A audio is sent to the headphones, taking precedence over the Headphone Source selection. Similarly, when held to the right or B position, RTN B audio is sent to the headphones. To latch on the return
in the headphone monitor, slide the RTN switch towards the desired return, slide again to turn off.
For momentary action, Hold the RTN switch for one second or longer.
The RTN A and RTN B LEDs illuminate in various colors and intensities to indicate signal presence,
green = signal activity, red = RTN clipping. The LEDs illuminate solid yellow to indicate the respective return is latched on. To adjust the gain of a respective RTN, hold the RTN switch and turn the
headphone controller.
Return audio can be sent directly to receiving devices using the Tape or Mono Mic outputs. See
Return Loopback for additional information. The RTN B TA3 connector can also be used as a Time Code
input. RTN B TA3 audio is disabled when time code is enabled. See Time Code for additional information.
Split Ear Return Monitoring
Split Ear Return Monitoring allows the user to monitor two sources at the same time. RTN A split
ear monitoring sends the RTN A summed mono signal to the left headphone monitor and the Right
program audio to the right headphone monitor. To activate RTN A split ear monitoring, press and
hold the Headphone Controller then slide the RTN switch left to the A position. When RTN A Split
Ear Monitoring is active the RTN A LED flashes yellow in a two pulse sequence.
RTN B split ear monitoring sends the RTN B summed mono signal to the right headphone monitor
and the Left program audio to the left headphone monitor. To activate RTN B split ear monitoring,
press and hold the Headphone Controller then slide the RTN switch right to the B position. When
RTN B Split Ear Monitoring is active the RTN B LED flashes yellow in a two pulse sequence.
RTN A/B split ear monitoring sends the RTN A summed mono signal to the left headphone monitor
and the RTN B summed mono signal to the right headphone monitor. To activate RTN A/B split ear
monitoring, press and hold the headphone controller then slide the RTN switch left to the A position
then right to the B position. Both RTN A and RTN B LEDs illuminate solid yellow when RTN A/B
split ear monitoring is active.
Return Loopback
During typical operation the 552’s Left and Right output buses are sent to both the Tape outputs and
the Mono Mic output. When set, Return Loopback allows Return A and/or Return B to be directly
routed to the Tape and Mono Mic outputs. To set Return Loopback Mode, press and hold the Battery
Check button and slide the RTN A/B switch to the Return position. The respective return becomes
the source for the Tape and Mono Mic outputs. To return to typical operation, press and hold the Battery Check button and slide the RTN A/B switch again. The respective RTN LED will flash yellow
when Return Loopback is active.
Return Loopback is useful for sending an IFB wireless feed of the RTN audio to the producer for

Powering
The 552 is powered by either internal batteries or external DC sources. 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.
The 552 is a power-efficient device and can run from four-AA alkaline batteries for approximately
eight hours (without phantom). As additional load is placed on the mixer, battery runtime is reduced. See Power Consumption for details.
Internal Battery Powering
Internal batteries can be used as either a primary power source or as a back-up in the event that
external power is removed or depleted. The 552 uses four AA-sized (LR6) batteries of various types.
Lithium primary cells, Alkaline, and NiMH rechargeable AA battery types are all popular battery
chemistries. The 552 achieves the longest battery runtime with Lithium and NiMH batteries.
There are similar sized 3+ V Lithium cells on the market which are not compatible with 552.
If the internal batteries drop to extremely low voltage levels while recording, the recorder will automatically close the file that it is recording to prevent it from being lost. The recorder is locked out
until the power source is switched to external or the 552 is powered down and batteries are changed.
External Powering
The 552 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.

Power Consumption
The 552 varies in the amount of current it draws. Several features of the 552 directly affect current
draw in different ways. The following list highlights the larger current drawing functions.
1. Microphone powering - the main source of extra 552 current draw. See Phantom Power. 48 V Phantom
can draw copious amounts of current out of the batteries, depending on what model microphone is
used. Two 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. Integrated Audio Recorder - the recorder, whether in record or playback, increases power consumption. Turn Record Mode off in the Setup Menu when not in use to extend battery run times.
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 Brightness - decrease LED brightness to extend battery runtime.
Slate Mic/Tone Oscillator
A single two-position switch controls both the slate microphone and the tone oscillator.
33
552 User Guide and Technical Information
Slate Microphone
The built-in 552 slate microphone is used to notate scenes from the mixer location. Its audio performance is not suitable for critical recording applications; it should be used for documenting scenes
and for communication purposes only.
The slate mic uses the left switch position. Slide the switch to the left to activate, and again to turn
off. For momentary action, hold the switch to the left for 1 second or longer. The LED adjacent to the
Mic/Tone switch will illuminate yellow when either Slate or Tone is latched on.
Program audio is muted while the slate mic is active. The signal is sent to all outputs and the Integrated Digital Audio Recorder. In the Setup Menu a one second, 400 Hz tone can be set to precede
the slate microphone. Additionally, the slate mic can be disabled to prevent unintended activation.
The slate mic is used as a communication system between the Sound Mixer and a Boom Operator
when using the Talk Back mode, selected in the Setup Menu. See Talk Back Mode for more details.
Tone Oscillator
Tone is used to set gain structure between the 552 and the next device in the signal path. The tone
oscillator uses the right position of the slide switch. Slide right to activate, hold for two seconds to
latch on. The LED adjacent to the Mic/Tone switch will illuminate yellow when either the Slate Mic
or the Tone Oscillator is latched on.
From the factory, the tone oscillator is set to output a 1 kHz sine wave at 0 dBu to the outputs (when
the outputs are set to Line Level). Tone is also sent at the same level to each of the Direct Outputs.
Tone level and frequency settings are configured in the Setup Menu. The 552 headphone outputs are
attenuated when tone is activated.
With Tone activated, press the Battery Check button to cycle the left output by -20 dB. This is used
to verify left and right output signals. Turn off the tone oscillator or press the Battery Check button
again to stop the output cycling.
Talk Back Mode
Talk Back Mode allows a Sound Mixer to have a private conversation with a Boom Operator using
the 552 slate mic. When in Talk Back mode, the Slate microphone is not routed to the 552 master
outputs, direct outputs, or to the recorder. The slate mic is sent only to the right channel of the 1/4inch and 3.5 mm headphones.
In Talk Back mode, the two 552 headphone outputs contain two different audio sources. The 1/4inch headphone output is used for the Sound Mixer’s headphones. Audio sent to the 1/4-inch
headphones is normal program. The 3.5 mm headphone output is used for the Boom Operator’s
headphones. Its audio source is menu-selected.
The audio signals sent to the 3.5 mm headphone output is set in the Setup Menu. Source is set as
