cancellation, automatic microphone mixing, matrix mixing, equalization, feedback elimination, dynamics
processing, delay, and submix processing.
The SR12 does not include acoustic echo cancellation processing but does includes noise cancellation,
automatic microphone mixing, matrix mixing, equalization, feedback elimination, dynamics processing,
delay, and submix processing.
All the SoundStructure products provide 24-bit A-D/D-A subsystems, 48 kHz sampling, and a dynamic range
exceeding 100 dB. A Voice over Internet Protocol (VoIP) interface and two different Public Switched
Telephone Network (PSTN) interfaces, a single-line and dual-line, are available.
Product Features
The Polycom SoundStructure C16, C12, C8 and SR12 offer the following features:
●16 (C16), 12 (C12 and SR12), or 8 (C8) balanced Microphone/line-level inputs
●48 V phantom power available on all inputs
●16 (C16), 12 (C12 and SR12), or 8 (C8) balanced line-level outputs
●Rear-panel Ethernet and RS-232 interfaces
●Logic input and output ports (requires firmware v1.3 or higher)

●Always disconnect the system from power before inserting plug-in cards into the SoundStructure
device.
●Only connect the system to surge protected power outlets.
●Only use electrical extension cords with a current rating at least equal to that of the system.
●Always disconnect the system from power before cleaning and servicing and when not in use.
●Do not spray liquids directly onto the system when cleaning. Always apply the liquid first to a static
free cloth.
●Do not immerse the system in any liquid or place any liquids on it.
●Do not disassemble this system. To reduce the risk of shock and to maintain the warranty on the
system, a qualified technician must perform service or repair work.
●Keep ventilation openings free of any obstructions.
●If the system or any accessories are installed in an enclosed space such as a cabinet or equipment
rack, ensure that the air temperature in the enclosure does not exceed 40° C (104° F). Forced cooling
may be required to keep the equipment within its operating temperature range.
General Site Requirements
Please ensure the SoundStructure side ventilation holes have at least 1 inch of clearance from the sides of
the rack to allow airflow through the device. Failure to maintain clearance for airflow may increase the
operating temperature of the unit beyond its maximum operating temperature of 40° C (104° F).
With the proper side clearance and airflow, each SoundStructure device requires one rack space and does
not require additional empty rack spaces above or below the device. When mounting with other equipment
give consideration to having access to the audio connectors on the rear-panel.
When using SoundStructure with RealPresence Group 700 video codecs, install the SoundStructure
devices with at least one rack unit of space between the SoundStructure and the video codec.
If you are placing the device on a tabletop or other flat surface (rather than rack- mounting it), it is
recommended to mount the adhesive rubber feet on the bottom of the device as shown in Rack-Mounting
the Polycom SoundStructure Device to prevent damaging the finish of the furniture surface.
