Introduction
Product Overview
The Soundman™ system is designed for three basic functions:
1. Provides improved audio over the standard hardware that ships with
videoconferencing group systems
2. Enables all participants to be heard in larger rooms
3. Provides a virtually invisible audio system when using CTG ceiling microphones
and speakers
The SM-02 is a single box microphone / speaker amplification system designed for
teleconferencing applications. The Soundman system functions as an audio peripheral
to a video codec without affecting or voiding the manufacturer’s factory warranty. Most
manufacturers’ enterprise group systems have been tested by CTG for compatibility. The
appendix provides integration information for common video codecs.
Microphones and speakers are proprietary to the SM-02 control unit. Microphones are
designed specifically for teleconferencing and are normally placed up to 10 feet from the
speaking individual. The ceiling speakers are designed to disburse the far end audio
source evenly throughout the room.
An installed system allows users to conduct meetings without restricting their actions to
accommodate the audio system. Ceiling microphones allow furniture to be moved about
freely without having to relocate cables or reconnect.

Videoconferencing
The Soundman system functions as an audio peripheral to a video codec. It may be
easily integrated into a set-top system or enterprise group system for larger rooms. The
added audio functionality does not complicate use of the system. The remote control
supplied with the videoconferencing system controls incoming audio and muting.
Audioconferencing
The Premier telephone interface connects to the SM-02 for audioconferencing
capabilities. The Premier is manufactured by Polycom®and has hardware and software
modifications for use with the SM-02. The Premier functions as a phone only
(commonly placed on a credenza) and may also be controlled through a wireless remote
offered by CTG. This modified version of the Polycom®Premier is only available
through CTG and is designed to function as a permanently installed system.
General Considerations
The Room
Most of today’s conference rooms outfitted for teleconferencing will not undergo
improvements for acoustics or noise reduction. Soundman systems are designed for a
typical conference room with an acoustical drop ceiling. The system includes ceiling
microphones that will be extremely effective in acoustical drop ceilings 10’ or lower.
Should there be a condition were the performance of the ceiling microphones would be
compromised, CTG offers a low profile table microphone, or a table implant microphone.
Room Reverberation
Good speech intelligibility is achieved in a room that is not excessively reverberant. An
acoustical drop ceiling in most rooms typically results in clear, intelligible speech being
transmitted to the far end when using ceiling or table microphones. When designing or
renovating a room for teleconferencing, there is an ideal specification for reverberation
time:
RT60 of less than 0.6 seconds
Reverberation time is defined as the time that is required for a sound to decay to one-
millionth of its original energy. There are different methods of improving intelligibility
in a poor room:
1. Treat the problem at the source:
• Sound absorbing fiberglass wall panels
• Heavy draperies
• Carpeting
• Acoustical drop ceiling
2. Substitute ceiling microphones with table microphones
3. Relocate microphones – rooms with a raised dome over a conference table will
sound hollow if a ceiling microphone is placed in the dome. Relocating
4

microphones outside the dome in the lower section of ceiling will result in better
sound.
Please contact CTG’s technical support for recommendations in challenging rooms.
Ambient Room Noise
When a teleconferencing system transmits excessive ambient noise it is very noticeable to
a quieter far end room. In addition, the transmitting levels are compromised and may be
too low to the far end. Soundman systems benefit from the noise reduction filter found
in most manufacturers’ video codecs. These filters range from 12dB-20dB in noise
reduction. In addition, the Premier telephone interface has a noise reduction filter of
20dB. Extremely loud rooms may still transmit a portion of the room noise. A room
being used for teleconferencing should try to meet the following ambient noise level:
NC-25 (Noise Criteria) – corresponds to about 35dBa in the human voice range
There are different methods of reducing excessive noise:
1. HVAC noise – Most HVAC systems may be adjusted to reduce the airflow or
turbulence to the vents but maintain an adequate level of heating or cooling.
Avoid placing microphones next to noisy vents.
2. Codec or computer fans – Isolate these devices in a cabinet, cart or separate room
when possible.
3. Projector fan – Microphones should not be placed next to a projector.
A group of people having separate conversations may create an ambient noise issue.
Please contact CTG for different methods of highlighting a presenter or muting an
audience area.
How to Layout a System
Room Usage
Before an audio system is considered for teleconferencing, the usable parts of the room
should be evaluated. For example, a conference table centered in a room will usually
require microphones over or on the table. The same room with seating along the walls
may require additional microphones or the locations would change to the perimeter of the
table. Please consult CTG technical support with any questions about microphone /
speaker placement.

Typical Configurations
The following drawings illustrate common room layouts:
TABLE
TABLE
This is typically a 20’L x 15’Wx 9’H
room. The videoconferencing system is
centered in the room lengthwise.
FLEXIBLE SEATING
CONFIGURATION
This is typically a 20’L x 20’Wx 9’H room.
The videoconferencing system is located at
the head of the table.
TABLE
The above ceiling microphone and speaker configurations provide even coverage for the
entire conference area in each scenario. Consider microphone placement as the first and
most important step of the installation. The microphone(s) are omni-directional and
should be centered over or between the meeting participants. The speakers are isolated
from the microphones by the echo cancellation in the codec during videoconferencing or
by the Premier telephone interface during audioconferencing. The videoconferencing
systems CTG is compatible with, meet the G.167 recommendation for convergence rate.
Speaker locations should be determined by the location of participants. The CTG ceiling
speaker has a wide dispersion angle of 120°.
This is typically a 30’L x 30’Wx 9’H room.
The videoconferencing system may be locate

Please consult CTG technical support for assistance with microphone / speaker
placement.
Installation
Required Cables
CTG recommends the following cables (not included with the system) for ceiling
components or table microphones running distances over 20 feet:
• Microphone – 22 gauge single pair shielded (Belden®type 82761 or equivalent)
6
Page 6 of 29

• Speaker – 18 gauge twisted pair (Belden®type 82740 or equivalent)
To comply with most building codes, wires that are running through air plenum space
must be Teflon™insulated unless they are enclosed in approved conduit. Every
microphone and speaker connects directly (homerun) to the SM-02. To avoid crosstalk,
do not run microphone and speaker cables through the same conduit.
Required Tools and Hardware
The following tools are recommended for the installation of the ceiling components:
• ½ inch drill bit – by simply twisting the bit through an acoustic tile, a perfect
hole will be made for the CM-01 ceiling microphone
• Hand saw – the ceiling speaker enclosure requires a 6 3/8-inch hole
• Wall snake – in most rooms, cables will need to be run down a wall and
terminated at the supplied wall plate
• Wire nuts – for ceiling speakers
• Electrical box – the supplied wall plate fastens to a single gang electrical box
• Small blade screw driver – often referred to in the industry as a “tweaker”
• Ladder
Microphone and Speaker Terminations
Microphone
Inside of the microphone you will find a four position terminal strip. Connections are:
Terminal 1 Positive
Terminal 2 Negative
Terminal 3 Shield
Terminal 4 No Connection
Remove jumper if tile is foil backed
or microphone housing contacts
building ground or metallic conduit.

There is a ground jumper between
terminals 3 and 4 that should be
removed if metallic conduit is used, or
if the ceiling tile is foil backed, or if
any part of the microphone housing
comes in contact with building ground.
Adjust the exposed length of the
microphone barrel by loosening the
setscrew accessible through the hole in
the side of the housing. Set it so that
the windscreen will be perfectly flush
with the room side ceiling surface.
A wall plate with a DB-15 connector
mounted on it is supplied and should be
installed in a standard single gang wall
box near where the equipment will be
located. All microphone and speaker
cables should be routed to this box and
connected to the terminal blocks provided on the wall plate. The microphone cables
should be separated from running close to the speaker cables to prevent any cross talk.

Speaker
The speaker enclosures supplied will require a 6 3/8-inch hole in the ceiling material.
The speaker grills are supplied with the speakers already mounted and attached to the
enclosures with torsion springs inserted into clips inside the enclosure. To remove the
grill simply pull it away from the enclosure and compress the springs to detach.
To simplify installation CTG attaches a twelve-inch wire to each speaker terminal so that
it may be connected with wire nuts. The red wire is positive.

Note that the wiring above has the microphones connected in out of phase pairs.
This results in some common mode noise reduction for noisy rooms. In quiet rooms
more even coverage may be possible with all the microphones connected in phase.
Please consult CTG technical support for custom wiring configurations.
Connecting to a Group Videoconferencing System
Connections
CTG requests systems integration information when a purchase order is submitted.
Based on this information the appropriate cables that interconnect the codec and the SM-
02 ship with the system. The quick setup sheets outline the connections and any settings
that should be changed to the codec.
Echo Cancellation / Digital Signal Processing
Soundman systems including the SM-02 are designed to use the echo cancellation and
digital signal processing internal to a video codec. CTG has designed the product line to
expand the capabilities of an enterprise group videoconferencing system.
Volume Control
Adjustments to the incoming audio should only be made through the videoconferencing
system. The speaker volume on the front of the SM-02 is a “set and forget” level. An
external volume control should never be inserted between the output of the codec and the
input of the SM-02.
Microphone Muting
Microphone muting should be performed through the video codec. External muting
would cause the acoustic model to be lost.
Multi-point Calls
Send levels may vary between videoconferencing systems. The far end may adjust their
volume control during point-point calls but level variations become problematic during a
multipoint. In addition, voice switching of locations will not work properly if the level is
too low.
