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.

Application
This section shows DM-NAX-8ZSA device in multizone applications.
This application diagram shows the following setup:
lUp to 8 zones of amplification and audio distribution
lLocal line level input
lLocal line level output to an Audio Video Receiver (AVR) mirroring a zone of amplification
lAvailable NVX audio streams to route audio from video sources to non-video zones
lAvailable music streaming services on up to 8 NAX zones

6 • DM-NAX-8ZSA Product Manual — Doc. 9045A
This application diagram shows the following setup:
lUp to 8 zones of amplification and audio distribution
lLocal line level input
lLocal line level output to an AVR mirroring a zone of amplification
lAvailable music streaming services on up to 8 NAX zones
lThe DM-NAX-16AIN is used to carry audio from the DM chassis’ video sources to the NAX
network for routing to non-video zones

Product Manual — Doc. 9045A DM-NAX-8ZSA • 7
This application diagram shows different 2.1 configurations and how they affect the zone count
of an DM-NAX-8ZSA. By default, a zone comprises two speaker outputs (a left and a right).
lThe 2.1 configuration at the left of the diagram comprises two speaker outputs, with an
additional line output that feeds the subwoofer.
NOTE: This configuration is only applicable for zones with an available line output (1
through 4).
lThe middle configuration (2.1 Bridged sub) comprises four speaker outputs - two left and
right and two for the bridged sub.
NOTE: This configuration is only applicable when enough subsequently numbered zones
are available on the amplifier. For example, the 2.1 Bridged sub cannot be used on Zone 8
as there is no speaker output pair 9.
lThe right configuration (Bridged 2.1) comprises six speaker outputs - two for the bridged
left, two for the bridged right, and two for the bridged sub.
NOTE: This configuration is only applicable when enough subsequently numbered zones
are available on the amplifier. For example, the 2.1 Bridged sub cannot be used on Zone 7
or 8 as there is no speaker output pair 9 or 10.

8 • DM-NAX-8ZSA Product Manual — Doc. 9045A
Having higher output-count zone configurations on a single DM-NAX-8ZSA will affect the total
available zone count on a given box. For example, if you have a single bridged 2.1 configuration on
an DM-NAX-8ZSA, it will lower the maximum zone count to six, as the bridged 2.1 consumes
three zones worth of speaker outputs on its own.
This application diagram shows the following setup:
lMirrored zones (Zone 1 and Zone 2 each have two rooms receiving the same audio signal)
lParallel wiring of low impedance speakers in two Locker Room areas
NOTE: This is a parallel wiring of 8 Ohm speakers for a total supported load of 4 Ohms
per channel. Parallel wiring lowers the effective impedance of the connected loads, so
make sure the speakers impedance matches the supported impedance levels from the
DM-NAX-8ZSA.

lUsing the line outputs of the DM-NAX-8ZSA to feed high-impedance amplifiers (AMP-
X300s and AMP-4600) for long speaker runs
lBussing to multiple zones to feed a large group of low-impedance speakers with the same
signal and shared controls
This application diagram shows a commercial setup using casting service streaming applications.
For example, in a hotel, each room can receive a cast from a third-party device. The Lobby and
Pool zones can exist on another DM-NAX-8ZSA unit that is on the same LAN or on a separate
VLAN or WAP to cast to/control those zones.

10 • DM-NAX-8ZSA Product Manual — Doc. 9045A
This application diagram shows zones using only the line outputs. Line outputs 1 and 2 feed high
impedance amplifiers driving speakers for large outdoor spaces and speaker zone outputs 5-8
feed low-impedance indoor spaces without overlap of signals. The LAN cloud shows that any
individual applications can exist as part of a large NAX system.
