If you set Active Microphone Volume to line in when using an external mixer or amplified
microphone, follow these steps:
1.
Select Line in (no AEC) for Active Microphone.
2.
Position someone approximately one meter from the microphone, facing it, speaking at
a normal volume.
3.
Adjust the Active Microphone Volume and the external mixer output level until the
meter peaks in the -28 to -22 dB range. Avaya recommends you adjust the external
mixer volume so that you achieve peak levels in the -28 to -22 dB range of the audio
meter with the Active Microphone Volume control set to no less than 5 or greater than
15.
4.
If the microphone or mixer you use employs an echo canceller, no further adjustments
are necessary. Otherwise, select Line In for Active Microphone. This turns on the
Avaya system’s echo canceller, noise reduction, and automatic gain control functions. If
you do not use an echo canceller, you may experience severe echo effects.
5.
After the adjustment, check that the peak levels when speaking normally one meter from
the microphone are in the -28 to -22 dB range. The AGC attempts to keep the transmit
level below -20 dB, which is the green range of the bar graph.
An audio meter is also available for the Line In Volume preference for setting an audio level
for a device connected to line in on the codec when line in is not selected as the active
microphone.
Audio Preferences: Video and Voice Call Output
If you plan to use external speakers other than Avaya Video Conference Phone 1000 for
audio output in both video and voice calls, ensure that the Video Call Audio Output and
Voice Call Audio Output preferences are set to Line Out. By default, Video Call Audio
Output is set to Line Out; Voice Call Audio Output is set to Phone. If you are using Avaya
Video Conference Phone 1000 for audio, set these preferences to Phone.
Audio Preferences: Testing Speakers
You can also test the primary output speakers for the appropriate audio level or to ensure
they are working properly. Select Auto for Primary Audio Output Test to cycle through a
test on your available speakers. The test continues until you select Off. You can also send
the tone to either the left or right channel by choosing Test Left or Test Right. The tone is
sent simultaneously to both line out and the HD video out of display 1.
