Make sure that the microphone pod is
positioned correctly for the meeting
configuration. If the microphone pod is
behind the meeting participants, you
may not be able to hear them speak. For
the best audio, always position the
microphone pod between the monitor
and the person closest to the monitor. As
most people face the monitor during a
call, following this rule ensures that the
meeting participants are also facing the
microphone pod.
You can also daisy-chain microphone
pods along the conference table. Follow
the same rule for multiple microphone
pods and do not position the pods
behind the meeting participants.
Turn down output of wireless
microphone. Put the ViewStation FX or
VS4000 in local loop and adjust
microphone output until you hear audio
coming back clear and crisp with no
clipping.
Connect the monitor or audio amplifier to
the monitor audio out of the ViewStation
FX or VS4000.
At the far site, make sure the
microphone pod is placed away from the
audio speaker.
Turn down the audio volume at the far
site.
Turn on the VCR input by selecting the
NEAR key twice and selecting the VCR
icon.
