Introduction
The Crestron DM-NAX-8ZSA is a next generation DM NAX™ Audio-over-IP (AoIP) amplifier that
puts Crestron multiroom audio distribution on the network. It provides eight amplified stereo
zone (16-channel) outputs. Four stereo line-level outputs mirror speaker zone outputs 1-4. A
dedicated streaming service player for each of the eight zones enables complete freedom to
stream different content in every zone. Full DSP capabilities are available on the line and speaker
outputs.
DM NAX is built on AES67 standards with the additional ease of configuration via a web
interface, SIMPL Windows, C#, and/or a RESTful API. It is compatible with DM NVX® endpoints
through an AES67 secondary audio stream and also with third-party AES67 solutions and
Dante® audio networking via the compatibility mode enabled in Dante Controller.
Voltage triggers corresponding to the 4 stereo line-level analog outputs can be used to power
connected external amplifiers on and off. The DM-NAX-8ZSA supports Synchronized Control to
manage a large network of DM NAX devices from a single interface.
For installation information, refer to the Quick Start Guide.

Physical Description
The following sections provide information about the connectors, controls, and indicators that
are available on the DM-NAX-8ZSA device.
Front Panel
The following illustration shows the front panel of the DM-NAX-8ZSA.
PWR: (1) LED, indicates operating power is supplied; illuminates amber
while booting, white when powered on, red when in standby (no audio or
LAN connection), and off when no power is supplied.
LAN: (1) LED, illuminates white when the amplifier is connected to a
network with a valid IP address, and off when the device is not
connected to a network or the IP address is invalid.
NAX: (1) LED, Illuminates white when the AoIP is ready to pass and the
unit's PTP clock is synced, and off when there is no AoIP is passing to or
from an amplifier and/or PTP is not synced.
SOURCE: (8) LEDs, illuminate white when a signal is detected on the
specified input/source, red when there is clipping on an analog input or
bitstream audio detected on a digital input, and off when there is no
signal detected on the specified input/source.
ZONE:(8) LEDs, illuminate white when there is audio output on the
indicated zone, red when clipping or a fault is detected on the zone
output due to overcurrent, over temperature, or low voltage.
