QUICK START GUIDE
SVSI NMX-ATC-N4321
Audio over IP Transceiver
Overview
The SVSI NMX-ATC-N4321 Audio Transceiver sends and receives audio over
IP. Balanced or unbalanced audio input coming into the N4321’s
AUDIO IN
port is converted into network packets for output through the RJ45 port.
Units can be stacked to deliver low-latency, multi-channel audio over a
house network or a physically separate network (using the two auto-sensing
gigabit Ethernet ports). One Ethernet port is Power Over Ethernet (PoE) for
use with a PoE switch, eliminating the need for an external power supply.
Since control is the same as SVSI’s video matrix, video and audio matrices
can be combined and routed using the same controller.

Establishing Connection
Before using your N4321 unit, it must be configured using the free N-Able
device management software. However, you will not be able to configure
units until they are in the same subnet as the host computer. N-Series
devices are shipped in Auto-IP mode with a default IP address of
169.254.xxx.xxx. The sample steps below show how the required changes
(to the host computer’s IP settings) are made in a Windows environment.
Steps for IP address configuration:
1.
From the
Control Panel > Network and Internet
dialog box, select
Network and Sharing Center
.
2.
Select
Change adapter settings
.
3.
Select the wired interface connected to your AV network.
4.
Click the
Properties
button.
5.
Scroll down in the list to the
Internet Protocol Version 4 (TCP/IPv4)
option. Highlight it and click the
Properties
button.
6.
Enable the
Use the following IP address
option, and enter the static IP
address
provided to you by your network administrator
. See FIG. 2.
FIG. 2
SETTING A STATIC IP ADDRESS
NOTE: If the computer does not need Internet access, you can simply enter a
unique 169.254.xxx.xxx IP address with a 255.255.0.0 Subnet mask. Contact
your network administrator if you are unsure of how to configure the existing
interface. If the computer already has a statically-assigned IP address, click
on the Advanced button. Then click Add to enter a unique 169.254.xxx.xxx
address with a subnet of 255.255.0.0.
Steps for auto discovering devices on the network:
1.
Use the host computer to download and install the latest version of
N-Able:
PC version -
http://www.amx.com/products/N-ABLE-PC.asp
Mac version -
http://www.amx.com/products/N-ABLE-MAC.asp
2.
Attach your N4321 unit(s) to the layer-3 network switch.
3.
Disable the wireless adapter on your computer (it must be hard-wired
to the switch).
4.
Connect the host computer to the layer-3 network switch.
5.
Open the N-Able application.
If all devices do not appear automatically, click the
Auto
Discover
button on
the
Unit
Management
tab. This issues a broadcast command that will
discover all units even if they are not in the same IP subnet.
Understanding the N-Able Interface
Once the host IP address is configured properly, you can view all discovered
units using N-Able. Access the N4321 units from the following tabs:
•
Unit Management
tab - N4321 units have
N4000 Audio
listed in their
Type
field.
•
Audio Matrix
tab - N4321 units have a musical note icon next to their
names (as shown in FIG. 3).

AUDIO MATRIX
In the
Audio Matrix
tab (shown previously in FIG. 3) Hover over a unit name
with your mouse to view tool tips providing critical information about each
device. Double-click any device to view its
Settings
page (shown in FIG. 4).
If prompted, enter
admin
and

Basic Installation Guidelines
Connections
Options
Power:
PoE:
Connect the unit’s
P0
port to an active, PoE-enabled
network switch
External power supply:
If not using PoE for power, connect a
12V regulated power supply (part number N9312) to the
unit’s two-pin terminal block plug connector labeled
+12V
2A
.
Network:
PoE units:
If using PoE to power the unit, you should already
have a network connection.
Externally powered units:
If not using PoE, connect the
P0
port
or
P1
port to the network with the appropriate cable
Audio:
For audio encoding, connect a line level analog audio source
to the
