AM 6040 Ambient Microphone Unit

Description

The AM 6040 Ambient Microphone Unit is a fully digital DSP microprocessor based
microphone unit designed to detect ambient noise in a conference room.

An ambient noise microphone is used to provide sound from the meeting, when
there is no speaker using the microphones. The microphone should be placed in a
central location in the room, not too close to anyone. This allows the microphone
to pick up sound from activities in the room like chairs being moved, paper being
picked up and e.g. low voices.

Transmission of ambient noise is desirable for listeners attending the meeting via
headphones. The ambient noise indicates to the listeners that there is no conversa­tion going on. This information is essential for interpreters when a speaker stops
talking.

The unit is designed to be installed above a recesses ceiling for connection to an ex­ternal microphone, like a model HM 4042. The AM 6040 is automatically recognized
and receives a unique address in the system, when connected to the DCS-LAN.

The AM 6040 is delivered in a shielded metal mounting box like the MU 6040.

Features

• Provides natural noise from the room during pauses in a
speech or brief breaks between agenda items.

• Connection to high-quality DIS electret condenser
microphones: GM 652x gooseneck or HM 4042 handheld
microphones.

• Supports LED indicators that display when the microphone is
on.

• Automatic activates the microphone when no Chairman or
Delegate units are active.

• Two RJ-45 ports provide power, audio, and control transport
across a single chain of chairman, delegate, and interpretation
units

• DCS-LAN connection uses CAT 5e (or higher) shielded F/UTP
or U/FTP cabling

• Adjustable volume setting from the browser interface

• One ambient microphone supports an entire the DCS 6000
system
