Advanced Use

Adjust the audio input levels according to which external audio equipment is connected. The on-screen audio
level indicator will make it easier to set the correct input level settings. The input level should be adjusted so
that the average level reaches the preferred level marker. The audio inputs are adjustable in steps of 1.5 dB
from 0 dB to 22.5 dB.

The default levels for Mic 1,2 and 3 are set for use with an Audio Technica AT871 microphone in an average
videoconferencing room. The gain can be adjusted correctly for a wide range of microphones.

A few examples of microphone levels are:

Audio Technica AT871

+3dB (default with system)

Audio Technica AT851R

+7dB

TANDBERG Audio Science

+19.5dB

Audio 4, 5 and 6 are set to a default level which is adhered to by most manufacturers of  audio-visual
equipment and is a level at which most audio-visual equipment (CD-players, VCRs) will work.
