AMX Audio-Only Module MAX-AOM - Manual (Page 10)

MAX-AOM Audio-Only (USB) Module
6 MAX AOM and AVM Modules
Additional Information on USB Ports 1 and 2 (on the MMS-04S, MMS-12S and
MMS-900 Servers)
If you are using both USB connectors on the MMS server, be sure to note which audio zones are
associated with the AOM connected to each USB port:
The USB 1 port is for audio outputs 1 through 4.
The USB 2 port is for audio outputs 5 through 8.
In this scenario, if the AOM connected to USB port 1 on the server (providing AOM outputs 1-4) is
unplugged or experiences any other failure, then USB port 2 takes over and behaves like port 1.
As a result, the AOM connected to USB port 2 will switch from providing audio output/zones 5-8 to
providing audio output/zones 1-4, the next time the server is rebooted.
Rack-Mounting the MAX-AOM
The MAX-AOM includes hardware for mounting the unit in a standard 19” equipment rack. A single
AOM takes up one-half of the width of a single rack unit, so you can mount two AOMs side by side in a
single RU by using the (optional) AOM-EX Expansion Kit (FG 2178-56). Refer to the next page for
details.
Using the AOM-EX Expansion Kit
The optional AOM-EX Expansion Kit (FG 2178-56) includes a MAX-AOM, a Side Mounting Bracket,
Short Rack-Mounting Bracket, and mounting hardware (FIG. 3). Use the Expansion Kit to mount a
second AOM next to the first one, in a single rack space.
The Side Mounting Bracket (FIG. 3) uses a set of six screws to connect to bracket to the side panel of
AOM #1. The bracket features tabs to ensure proper positioning and alignment of the two AOMs, and
four screws (two on the front and two on the rear) to secure the AOM #1/side bracket assembly to AOM
#2.
Static electricity can damage electronic circuitry. Before mounting the AOM(s),
discharge any accumulated static electricity from your body and screwdriver by
touching a grounded metal object.
