Description
Tests the audio cable connections. A 473 Hz audio tone
indicates that the local audio connections are correct.
If you run the test from the system during a call, the far site
will also hear the tone.
If you run the test from the Polycom QDX 6000 Web
interface during a call, the people at the site you are testing
will hear the tone, but you will not.
Measures the strength of audio signals from microphone(s),
far-site audio, VCR audio, and any device connected to the
audio line in.

To check the microphone(s), speak into the microphone.

To check far-site audio, ask a participant at the far site to
speak or call a phone in the far-site room to hear it ring.

To check a VCR or DVD, connect it to the VCR inputs
and play the VCR or DVD to test the audio.
The Audio Meters indicate peak signal levels. Set signal
levels so that you see peaks between +3dB and +7dB with
normal speech and program material. Occasional peaks of
+12 dB to +16 dB with loud transient noises are considered
acceptable. A meter reading of +20dB corresponds to
0dBFS in the Polycom QDX 6000 system audio. A signal at
this level is likely clipping the audio system.
Meters function only when the associated input is enabled.
Note: Some audio settings are unavailable when a
SoundStructure digital mixer is connected to the Polycom
QDX 6000 system.
