When music is
played during the
call, it sounds
distorted at the
other sites.
The music source is not
connected to the system.
The system’s echo cancellation
and noise suppression features
may interfere with music that
the microphone picks up.
Connect the music source to the system’s audio
input.
Stereo audio
comes from the
wrong speaker.
Speakers are connected
incorrectly.
Connect the speaker on the left to the system’s
white audio output connector, and the speaker on
the right to the red audio output connector.
Video and audio
are not
synchronized.
The video quality for the
camera in use is set for
Sharpness. This setting is for
images with no motion.
1) Go to
System > Admin Settings > Cameras >
> > Video Quality
.
2) Change the Camera Settings to
Motion
.
Voices at the
near site sound
distorted through
the speakers at
the near site.
The far site has distorted audio
from the far-site speakers.
The far site's distorted audio is
often caused by overloading
the input stage of the far site’s
audio amplifier.
Ask the far site to reduce their Polycom QDX 6000
system volume control to about 25, and to increase
their external audio amplifier volume control to
maintain the same loudness.
The Audio Meter
screen shows a
reading for
Polycom Mic but
no microphone is
connected - the
system receives
local audio from a
mixer.
Echo cancellation is in use. The
system displays the audio line
input level in this case.
This is normal.
