Preparing For Installation
This chapter introduces the Polycom® SoundStructure™C16, C12, and C8
audio conferencing devices, and the SoundStructure SR12, a sound
reinforcement product which is compatible with the Polycom SoundStructure
C16, C12, and C8.
This chapter contains the steps to follow before installing this new hardware
and includes information on:
•Overview
•Installation Overview
•Tools Needed For Installation
•General Site Requirements
To install the Polycom SoundStructure hardware, refer to Installing The
Hardware on page 2-3.
Overview
The Polycom SoundStructure C16, C12, and C8 audio conferencing devices are
audio processing devices that have 16 inputs and 16 outputs (C16), 12 inputs
and 12 outputs (C12), and 8 inputs and 8 outputs (C8).
The C16, C12, and C8 versions of this product line features acoustic echo
cancellation (AEC), noise 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. Two different Public
Switched Telephone Network (PSTN) interfaces, a single-line and dual-line,
are available.

Tools Needed For Installation
The following tools will be required to install your Polycom SoundStructure
unit:
•A Phillips head screwdriver for installing rack ears and rack-mounting the
device.
•A small blade screwdriver for terminating audio cables to the terminal
blocks.
Safety Recommendations
Read and understand the following instructions before using the system:
•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.
Warning
Save these safety instructions.

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, 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 Polycom HDX video codecs, it is
recommended that the SoundStructure devices be installed above 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.
Power Supply Considerations
The Polycom SoundStructure C16, C12, C8 and SR12 have the following
power requirements on the line power supplied to the devices:
•Input voltage of 90-250 VAC; 50-60 Hz
•Line power requirements (including 0.6 PF):
—130 VA (C16),
—115 VA (C12),
—105 VA (SR12),
—95 VA (C8)
