DNM2-ETH
Connect the DNM2-ETH device(s) using STP CAT5/6 cable to the network switch via LAN, then the
DNM2-ETH device(s) will be discovered by Boutique system automatically and displayed on the web
browser.
3.18.1 Installation notice
Install the DNM2-ETH to the position in which the DNM2-ETH can detect the background noise and
automatically adjust the speaker level. Up to 8 DNM2-ETH devices can connect to each BOUTIQUE
local network, and up to 256 DNM2-ETH devices can connect to a BOUTIQUE system (8 DNM2-ETH
x 32 local networks).
When the loudspeakers are placed in a big area such as railway station hall, loudspeakers are put in
different locations, which requires to install multiple DNM2-ETH units for having clear enough sound
for each position of the area. Then users need to assign multiple DNM2-ETH units in a DNM group.
Please note a DNM group can only be applicable to one BOUTIQUE zone.
The distance between DNM2-ETH 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.
Examples of installation:
1. Install the DNM2-ETH in front of the
loudspeaker about 1.5~3 meters.
