TANDBERG D50104-15 user manual Audio Outputs, Level Settings

Health Care System III Advanced Use

Level Settings

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.

Audio Outputs

Audio out 1 is intended for connection to TANDBERG Natural Audio, televisions or audio amplifiers.

Audio out 2 is intended for connection to audio recording equipment or to a telephone add-on hybrid. The signal is a mix of audio from both the far end and local end (not from Audio in 5).

Audio out 3 is intended for connection to a VCR or other recording equipment. The signal is a mix of audio from far end and local end (not from Audio in 6).

Audio Module: Select Natural Audio Module according to the type of Audio Module installed.

NOTE

NEVER CONNECT AUDIO OUT 2 OR AUDIO OUT 3 TO A LOUDSPEAKER PLACED IN THE SAME ROOM AS THE MICROPHONES CONNECTED TO THE

SYSTEM. DOING THIS WILL CAUSE “HOWLING” AND POSSIBLE DAMAGE TO THE SPEAKER SYSTEM.

If an output is ‘Off’, no audio will be sent to that output.
