3.2.3.1.1 DNM-ENET
Install the DNM device to the position in which the DNM can detect the background noise and
adjust the speaker volume automatically, and connect the DNM with audio processor by Ethernet.
If the system needs to connect to a series of DNM, connect the ethernet cable to the DNM
devices, then the DNM devices will be auto searched. Please refer to DNM-E > Configuration >
Step 3 > Deploy to learn how to assign the master/slave DNM units.
One DNM can only support one zone(like IDA8 Zone Channel). Generally, place the DNM in front
of a loudspeaker about 1~2 meters. The distance between DNM and speaker also relies on the
power of the amplifier and loudspeaker. If it is a high-power loudspeaker (sound is louder), then the
distance should be increased, and vice versa.
The examples of installation as follows:
1. One zone connects to one loudspeaker only, generally, then install the DNM in front of the
loudspeaker about 1~2 meters.
2. One zone connects to many loudspeakers, and installed the loudspeakers by circularity and
the distance is not far between the loudspeakers, then the DNM can be set in the center of
loudspeakers (eg: A small conference room etc.).
3. One zone connects to many loudspeakers, and the installation of loudspeakers are irregular
but the distance of all loudspeakers are not far, then install the DNM about 1~2 meters in the
front of any one loudspeaker.
