Harman AMX NMX-ATC-N4321D Quick Start Manual

Overview

The SVSI NMX-ATC-N4321D Audio Transcoder with Dante is an audio-over-IP solution
that sends and receives multichannel balanced or unbalanced audio over IP. The NMX-
ATC-N4321D can receive an analog audio input and convert that into network packets,
allowing the user to switch and route the audio, just like data and voice.The balanced
analog audio output receives an audio-over-IP stream and decodes to analog while
preserving audio fidelity. The NMX-ATC-N4321D provides audio matrix switching and
distribution using the same control options as SVSI's Networked AV video switching and
distribution solution. One Ethernet port is PoE for use with a PoE switch, eliminating the
need for an external power supply.

Attaching Signal and Control Cables

The following table explains how to attach cables to the Audio Transceiver.
IMPORTANT: Audio Transceiver must be securely mounted and connected to the
switch before attaching the remaining cables.
NOTE: Disable the wireless adapter on your computer (it must be hard-wired to the
switch).

Establishing Connection

N4321D Audio Transcoder are shipped with DHCP as their default IP mode. The IP
address is assigned automatically based on the network DHCP server. If no DHCP server
is found, the unit will use Auto IP mode instead (with a default IP address of 169.254.
xxx.xxx).
Before using your N4321D Audio unit, it must be configured using the free N-Able device
management software. However, you cannot configure units until they are in the same
subnet as the host computer. 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.
Select Change adapter settings.
2.
3. Select the wired interface connected to your AV network.
4. Click the Properties button.
5. Scroll down 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.
NOTE: If the computer does not need Internet access, enter a unique
169.254.xxx.xxx IP address with a 255.255.0.0 Subnet mask. If the computer 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. Please contact your
network administrator if unsure how to configure the existing interface.
▪ Steps for Dante's IP address configuration:
1. Use the host computer to download and install the latest version of Dante
Controller:
PC Version -https://my.audinate.com/support/downloads/dante-controller
2. Attach your N4321D Audio unit(s) to the managed network switch.
3. Connect the host computer to the same managed network switch.
4. Open the Dante Controller application.
5. Refer to the Dante Software and directions to configure the IP address.
▪ 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-C.asp
2. Attach your N4321D Audio unit(s) to the managed network switch.
3. Connect the host computer to the same managed network switch.
4. Open the N-Able application.
Note: 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.
▪ Logging in Using N-Able Software
Once the host IP address is configured correctly, you can view all discovered units
using the N-Able software. Access the N4321D Audio units from the following tabs:
• Unit Management tab – N4000 Audio is listed in the Type field.
• Audio Matrix tab – N4321D Audio units are found on the SVSI Audio sub-
tab of this screen.
