18 gauge twisted pair (plenum rated) Belden type 82740 or equivalent 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. -

(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. -
Page 11: Panel Descriptions
Page 11 Panel Descriptions The FS-400/800 powers the CTG microphones and can be linked to support an unlimited number of microphones. The PSTN phone line connection allows for stand alone audio conferencing and the Interfaces are easily integrated to video conferencing codec’s. - Page 12 110 to 240 volt mains.

(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. -
Page 14: Calibration For Audio Conferencing
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. -
Page 15: Calibration For Video Codec
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. -

Easy to use CTG Windows recording software is included. Instructions for recording can be found in the recording software utility help file. (Illus. B) (Note: when using the FS-400/800 output for recording within a room, a codec or other line level device may not be connected) -
Page 17: Linking Multiple Mixers
Page 17 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. -

• The microphones are picking up excessive room noise The send (output) level may be set too high in the FS-400/800 software increasing the microphone sensitivity level. The Microphone slider in the CTG software should be moved down until all or most of the ambient noise disappears without the loss of adequate voice pickup. -
