Audio Mapping for TalkShow VS-4000

The audio input channels are mapped serially to the Skype Channels. Put another way, each TalkShow Skype channel, has up to 4 audio channels that can be mixed down to mono and sent to Skype. Audio channels 3 and 4 can only be received through SDI embedded or NDI embedded sources.

Input 1: Embedded or Line In.  The Line In is both XLR L and XLR R on the back of the unit, mapped as channels 1 & 2.
Input 2: Embedded Only.
Input 3: Embedded Only.
Input 4: Embedded Only.

If you are using the motherboard sound card, then you will see it appear as channels 1 and 2 in the TalkShow.

You can hear audio on channels 3 and 4 thru Skype.  All four channels of input will be mixed into the mono Skype channel.  I would suppose that audio phase could cause some major cancellation issues, so I would highly recommend only feeding a mono source into each Skype channel.

The RealTek Line input is stereo, giving two independent audio channels. Being that is mapped serially, the first input or “left” signal will map to channel 1 and the second input or “right will map to channel 2. In this configuration, channels 3 and 4 would not be used. The table below may help visualize the mapping.

In the chart below, you will use ‘Input 1’ twice for both Talkshow channel 1 and 2.
