- If the inside and outside microphone have no sound within a meter, this would mean that they
are in Silencing Noise situation, and this noise is being eliminated or you would have to turn up
the volume.
- If you want to record the sound from the inside and outside working room, the desk microphone
has an output REC function available.
- In one side of the microphone desk there is a volume control to adjust the speaker and
microphone extension (Fig.1.3).
- Before installing the system, you should adjust the desk microphone and the microphone and
speaker extension sensibility to the ideal level in order to avoid self excitation and to reach the
desirable volume in both sides.
