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
1
Overview
• General Site Requirements
To install the Polycom SoundStructure hardware, refer to Installing The
Hardware on page 2-3.
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.

accessory.
For a complete list of available SoundStructure Accessories, see Accessories on
page 5-1.
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.
Preparing For Installation
• 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.
Save these safety instructions.
Warning

Hardware Installation Guide for the Polycom SoundStructure C16, C12, C8 and SR12
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)

Plug-in Card Installation
Each SoundStructure device can have a plug-in card installed for a total of
eight plug-in cards in a collection of eight SoundStructure devices. When
installing more than one plug-in card in an installation, it is recommended to
use the plug-in slot from the top device first and continue sequentially down
through the collection of devices as additional plug-cards are added.
Warning Do not insert a plug-in card while the SoundStructure is powered on.
Failure to remove power prior to installing the plug-in card may damage the plug-in
card and/or the SoundStructure device.
To install a plug-in card, follow these five steps:
1. If plugged in, unplug the AC power cord from the SoundStructure
device.

Rack-Mounting The Polycom SoundStructure Device
The Polycom SoundStructure can be mounted in an equipment rack, or placed
on a tabletop or other flat surface, or mounted under the table with the
optional undertable mounting kit.
Each SoundStructure device requires one rack space and does not require
Warning
additional empty rack spaces above or below the device.
When multiple devices are racked together, before final tightening of the rack mount
screws on each device after the first one, ensure there is enough clearance so that
the front-panel door will open freely.
To rack-mount the SoundStructure unit:
1. Remove the four front screws on the enclosure.
2. Align the rack ears, and install the rack ears using the screws that were
removed from the enclosure.

The SoundStructure device's Ethernet interface (as shown following figure) is
a 10/100 Mbps interface that supports Auto-MDIX (medium dependent
interface crossover).
Auto-MDIX enables the use of a standard CAT5e cable to connect directly
from the SoundStructure device to either an Ethernet network or to a
computer. The SoundStructure device will detect the connection and work
appropriately.
Installing The SoundStructure C16, C12, C8, And SR12
By default the SoundStructure device has Dynamic Host Configuration
Protocol (DHCP) enabled and will accept an IP address from a DHCP server.
The SoundStructure device IP address can also be set to a static IP address
using the SoundStructure Studio software.
Do not plug the Ethernet cable in to the Conference Link2 ports. To minimize
improper cabling, plastic plugs have been installed by default into the
Conference Link2 ports.
Warning Connecting an Ethernet cable into the Conference Link2 interface of a
SoundStructure device could damage the SoundStructure device.
Connecting To Other Polycom Equipment With Conference Link2
The Conference Link2 interface (shown in the following drawing and labeled
C-Link2) is used to connect the SoundStructure devices to other Polycom
equipment such as a Polycom HDX system. There are two Conference Link2
interfaces on each SoundStructure device to support future connectivity to
more than one Polycom device. The Conference Link2 ports on the
SoundStructure devices have a plastic plug that must be removed before
inserting a cable into the Conference Link2 ports. The Conference Link2 ports

cables - see Conference Link2 for pinout details) to enable field termination of
custom length cables using standard RJ45 plugs and standard crimping tools.
Warning Connecting a Conference Link2 cable to the Ethernet interface could damage the
connecting device and/or the SoundStructure device.
Using the supplied 18” Conference Link2 cable, connect one Conference Link2
port on the SoundStructure device to a Polycom microphone Input port on the
Polycom HDX system as shown in the following figure. If there are multiple
SoundStructure devices linked together with OBAM Link, only one
SoundStructure device should be connected to a Polycom HDX system.
2 - 8
Warning A CAT5e cable that is terminated with standard T568A or T568B pin/pair
assignments will not work with Conference Link2. The Conference Link2 pinout is
different from T568A or T568B pin/pair termination.
Do not use a standard Ethernet cable to connect SoundStructure to a Polycom HDX
system.
If a longer Conference Link2 cable is required, one may be constructed using
the custom pinout (see Conference Link2) and standard 8P8C (eight positions,
eight conductors, e.g., RJ45) connectors, shielded Cat5e cable or better, and
standard 8P8C crimping tools. Note that the maximum length between the
Polycom HDX codec and the SoundStructure device is one hundred feet
(30m).
