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.

“Full SD Card” is announced when there is no space remaining on the SD card and a record command has been given.
“Record Mode Off” is announced if the recorder receives a command and the recorder is disabled
in the Setup Menu.
Press the Recorder Controller in stand-by mode to announce the file number of the next take to
be recorded.
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.
