Installation and wiring of CTG Microphones and Speakers
Tools Required for Installation
The following tools are recommended for the installation of the ceiling components and
setup:
 ½inch drill – for drilling 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 run down through a wall and
terminate at the FS-400, FS-800
 Wire nuts – for ceiling speakers
 Wire Stripper
 Small blade screw driver – often referred to in the industry as a “tweaker”
 Ladder
CTG Microphones-General
CTG microphones are true 360° Omni directional. They are electret condenser boundary
microphones. The microphone itself should be flush mounted in a boundary of at least
12” in diameter. The element in the table top microphone (TM-01) is mounted in a base
designed to acoustically couple to the table surface and provide an adequate boundary.
CTG microphones connect to microphone Inputs.*
* Each microphone must connect directly to the FS-400/800 with a “homerun”
connection.
Recommended Microphone Cable
 22 gauge single pair shielded (plenum rated) Belden® type 82761 or equivalent
CAUTION:
 Phantom voltage supplied to CTG microphones can be 2 to 50 Volts DC. The FS-400/800
microphone inputs provide 24 volts DC
 To avoid crosstalk, it is preferred microphone and speaker cable NOT be bundled or run
together in the same conduit over long distances

The speaker enclosures supplied will require a 6 3/8-inch hole in the ceiling material.
Ceiling Speaker (SP-01) Mounting Detail
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
grille 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: Blind mounts are available from CTG for dry wall ceilings or ceilings with
inadequate space above. Tile bridges are also available as an option.)
Although the FS-400/800 mixers do not contain a speaker amplifier, it is vital that return
audio from an external video codec be routed through the mixers before being connected
to a speaker amplifier. This allows the return audio to be sampled to enable echo
cancellation. To facilitate this there are SPEAKER IN and SPEAKER OUT
connections on the rear panel of the mixers.
Each speaker has a
direct “homerun”
connection to the
speaker amplifier
Recommended speaker cable:
18 gauge twisted pair (plenum rated) Belden type 82740 or
equivalent

FS-400 and FS-800 Beamforming Teleconference Interfaces
Overview
The CTG FS-400 and FS-800 Beamforming Mixers are an advanced solution for group
audio and video teleconferencing, intra-room presentations, and meetings with recording
capacity. They differ only in the number of microphone inputs (4 or 8), and both include
a telephone interface to connect directly to the Public Service Telephone Network
(PSTN). They can also connect at Line Level to any Video codec with a suitable Line
Level input connection. The FS-400 and FS-800 may be daisy chained to allow a nearly
infinite number of microphones. Any mixer in the chain may be the master. The mixers
provide advanced Echo Cancellation, Noise Reduction, and De-Reverberation to reduce
the room reflections that can seriously degrade speech intelligibility. Simple software is
provided to set audio levels for the microphone mixer and the telephone interface.
Recording software is also included. A dial pad is included to dial, connect and
disconnect phone calls.
Both of the mixers take advantage of the increased computational power of the latest
digital processors to provide enhancements not previously available. Every attached
microphone is sampled 16,000 times per second and the audio picked up by each is
analyzed and compared in arrival time. Audio from any microphone that enhances
intelligibility of a person speaking is combined, while audio that would degrade
intelligibility is discarded. The system constantly adjusts to changes and effectively
follows a moving speaker.
Noise Suppression- Noise suppressor acts on long term noise (HVAC noise, fans, and
lighting hum.
De-Reverberation- All sounds in a room are reflected from room surfaces. A de-
reverberation algorithm determines reflections by comparing the time difference with the
original sound and reduces annoying room echoes. As a result rooms that have marginal
acoustic characteristics for good teleconferencing are made usable.

Connecting and Placing Audio Conference Calls
For audio teleconferencing over standard analog PSTN phone lines there are two
options. First connect the FS-400/800 to the standard RJ-11 telephone wall jack from the
similar jack marked Phone Line on the mixers front panel.
1. A software dialer, similar to the hardware dial pad but with additional capabilities,
such as Flash, Mute, Volume, and Number Recall is included on the supplied software
CD, and may be used instead of the hardware dialer shown below through the USB Data
port.
2. Or attach the included hardware telephone dial pad to the narrower jack marked
Dialer. To place a call press the button at the top of the dial pad showing a telephone
handset, and dial when the dial tone is heard, to hang up after the conference, press the
same button again. (see Illus. A) Telephone volume level can be adjusted with the
CTG Setup Software (Page 18). There are two additional buttons at the top of the dial
pad that can be pressed to conveniently redial the last dialed phone number.

Calibration for Audio Conferencing
It is important to maintain “standard transmission levels” with handsets, speakerphones
and conference phones. The standards that reference “Send Loudness Ratings” (SLR) are
described in the ITU’s G. 111 standard and also referenced in the P. 340 standard.
The goal is to maintain a dynamic range >20db as described in the videoconferencing
calibration section. The speech level should average +6db to ensure a comfortable level
at the far end.
In General, the audio level of people speaking in the distant rooms should be about the
same as a person speaking in the same room with you.
Integration to Video Conferencing
Codec Compatibility
The FS-400 and the FS-800 are compatible with almost all video codec’s.
Connecting the Codec
The FS-400/800 Output should be connected at line level to a video codec. CTG will
provide the appropriate connecting cable for the particular codec model if known. The
following illustration shows the connection between video codec and the microphone
mixer. For specific illustrations and instructions to connect to commonly used codecs
refer to the support section of www.ctgaudio.com or call CTG support at [phone]
Codec (Rear Panel): NOTE: This Illustration is a simulated codec panel and does not
represent any particular brand.

Calibration for Video Codec
It is important to maintain “standard transmission levels” to be compatible with other systems.
The following illustration details the targeted send level.
Some codecs have an audio meter that displays the transmission level.
Ideally the output level of the mixer should be adjusted so voices peak between +5 to +10 dB.
CTG technical support can assist in determining the proper send level over a video call.
During calibration, the volume control indicator of the video codec should be set at about mid-
range. Typically the video codec will display an on screen graphic that will indicate the incoming
audio level when a volume key is pressed.
-20 -15 -10 0 +5 +10 +15
Ideal noise floor – noise should not
be detected at the distant end if the
ambient noise floor is under -12dB
Ideal speech level – adjust send
level so average speech peaks at
+8 to +10
Dynamic range goal = >20dB
FS-400/800 provides
exceptional signal to
noise ratio

Recording a Conference
Audio recordings can be made of a conference by connecting a computer to the front
panel USB Jack on the FS-400/800 and recording to a computer hard drive. This may
also be used to record meetings within a room. When another recording device is used to
record within a room (no teleconferencing) the output jack on the back panel can be
connected at line level to a recorder. (See Illus. B)
Easy to use CTG Windows recording software is included. Instructions for recording can
be found in the recording software utility help file.

(Note: when using the FS-400/800 output for recording within a room, a codec or other line level
device may not be connected)

Linking Multiple Mixers
A short linking cable is provided with every mixer. Any number of FS-400 and FS-800
mixers can be linked to support any number of microphones required. The link
connectors on each end of the cable are different to prevent being plugged into the wrong
LINK jack. (see illus E) Any mixer in the chain can act as a master or slave, Any
software level change made to any mixer will be applied to all the mixers in the chain.

CTG Software
To load and use setup software, connect USB cable to front panel data port,(see illus. D)
(Illus. D)
The CTG Audio Setup Utility is designed to help you control the audio levels coming in
and going out of your CTG product. This utility will:
1) Identify the CTG device you are using and indicate whether it’s connected (or not
connected).
2) Set the audio levels to a comfortable default value. Once you modify the levels the unit
will save and restore your preferred levels anytime you connect a unit or open the audio
utility (you can choose not to save your settings and to go back to the default values).
3) The utility will allow you to control the level of signal going to and coming back from
your telephone. It will also allow you to control the level and balance of the bridge (the
connection between your telephone counterpart and VoIP counterpart in PSTN versions)
This utility is not necessary in order to use your CTG system. Some audio levels (VoIP)
can be controlled through your Windows mixers while others that are not controlled by
Windows (telephone and bridge) are set to a comfortable default level. However, this
utility adds another level of control that some users prefer to have.
An important feature of the utility is the ability to disable / enable the bridge connection.
This is intended to prevent your telephone counterpart from hearing unwanted sounds
coming out of your computer.
The software must be installed to a laptop or desktop computer running Microsoft
Windows 98 or newer, and connected to the FS-400 or FS-800 mixer with the provided
USB cable to the front Data Port on the mixer. The indicator will turn from Red to Green
and indicate the device is connected. If you already have an older version of the CTG
