DCS 6000 Digital Conference System
Type Description
AM 6040 Ambient Microphone
The AM 6040 Ambient Microphone Unit is designed to
detect ambient noise in a conference room.
The purpose of an ambient microphone is to provide sound
from a meeting room/conference hall, when there is no
speaker/chairman active using their microphones.
The microphone should be placed in a central position in
the room, but not too close to anyone; thereby the
microphone is able to pick up sound from activities in the
room/hall (chairs being moved, paper being picked up, low
voices and so on).
Transmission of ambient noise rather than transmitting no
sound at all is a desirable feature from listeners attending
the meeting via headphones. The ambient noise indicates
to the listeners, that there is no speaking activity going on,
and this information is very nice to have, when interpreters
are doing interpretation, and the speaker stops speaking.
The AM 6040 Ambient Microphone Unit is designed for
installation above a recessed ceiling for connection to an
external microphone like DIS model HM 4042 or GM 652x
series of gooseneck microphones.
The AM 6040 is delivered in a shielded metal mounting box
like the MU 6040.
•
Automatic activation of the microphone, if no Chairman
or delegate units are turned ON and the LineIn Volume
(LineIn>Loudspk) is set to OFF.
•
Setting of the volume of the ambient noise audio level
on the CU 61xx.
Note: One ambient microphone can be active in the
DCS6000 system at one time.
