Using the Channels Page

After you have created the design, the Channels page displays where the following virtual channels and

virtual channel groups have been defined.

Virtual Channels and Descriptions

A virtual channel group that includes Table Mic 1

A table top microphone with phantom power enabled and a default gain of 48dB

The audio output from the VSX8000 that is an input to the SoundStructure device

The output to the amplifier that will drive audio into the local room

The audio output from the SoundStructure device that is an input to the video codec

A signal generator that can be used for setting amplifier volume levels and checking that

loudspeakers are connected.

These channels are shown in the channels page in the following figure. The input gain for tabletop

microphone is set to 48dB. Since the VSX8000 has a 0 dBu nominal input and output signal, the input gain

for the VSX8000 In channel is set to 0dB, in other words, no gain is applied. It is also assumed that the

Amplifier can accept the nominal 0dBu level from the SoundStructure device, allowing the SoundStructure

Amplifier output to have 0dB output gain. If the Amplifier input has an RCA connection, the Amplifier output

gain adjusted from 0dB to -10dB to prevent overdriving the consumer-level input on the Amplifier.
