FAQ-Why Is the Sound Collected by the VPM220 or VPM220W So Quiet

Publication Date:  2015-08-07 Views:  252 Downloads:  0
Issue Description
I use a VPM220 or VPM220W to collect sound, but the volume of a participant in a specific location is too low. What can I do?
Solution
You may have enabled stereo mode. In stereo mode, one of the VPM220W microphones does not collect sound.

Select an appropriate audio protocol and sound pickup mode, and correctly place the VPM220 or VPM220W according to the user guide.
  • Mono mode
When VPM220 or VPM220Ws are cascaded or a VPM220 or VPM220W works over a mono audio protocol, all the microphones collect sound.
  • Stereo mode
When a VPM220 or VPM220W works in a stereo audio protocol, one of the VPM220 or VPM220W microphones does not collect sound.
