TESTING THE AUDIO INPUTS AND OUTPUTS
1. Go to System, Diagnostics, Audio, Audio Meter and then speak into one of the microphones. Your
level should be around 0 on the Line Input meter. You may also use the loop-back feature to listen
to your own audio in the local room. That feature is under System, Diagnostics, Network, Near End
Loop.
2. Go to System Info, Diagnostics, Audio, Generate Tone to listen to a codec-generated 400 Hz tone.
WIRING FROM VSX 7000 TO VORTEX DEVICE
The inputs and outputs to most codecs are unbalanced. We recommend keeping the cable
from the Vortex device as short as possible to avoid any common-mode signals that may
corrupt the audio.
INPUT TO VSX 7000 FROM OUTPUT OF VORTEX DEVICE
Connect the Positive conductor of the Vortex device to the Tip of the RCA connector and the Negative
conductor of the Vortex device to Shield of the RCA connector.
The shield of the cable is not connected.
OUTPUT OF VSX 7000 TO INPUT OF VORTEX DEVICE
Connect the Positive conductor of the Vortex device to the Tip of the RCA connector and the Negative
conductor of the Vortex device to Shield of the RCA connector.
