DM-NAX-8ZSA
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.
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.
The DM-NAX-8ZSA supports Amazon Connected Speakers.
For installation information, refer to the DM-NAX-8ZSA Quick Start.

NOTES:
lDM NAX devices generate multicast traffic on the network. Even a single DM NAX
device connected to an unmanaged network can cause communication issues with
other devices connected to the same network. For information on system installation,
refer to the DM NAX™ Audio-over-IP System Design Guide.
lIf DM NAX devices must be set up before configuring network settings on a managed
switch, use the Port Selection (on page119) functionality on the DM NAX device to
isolate the AoIP traffic to the secondary Ethernet port. For example, when connecting
the DM NAX to a control system or authenticating streaming service accounts. This
ensures that during setup, the primary Management port of the device does not
receive AoIP traffic.
This application diagram shows the following setup:
lUp to eight 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 DM NVX audio streams to route audio from video sources to non-video zones
lAvailable music streaming services on up to eight DM NAX zones

lLocal line level output to an AVR mirroring a zone of amplification

lThe DM-NAX-16AIN is used to transmit audio from the DM chassis’ video sources onto the

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.

10 • DM NAX™ Product Manual — Doc. 9045H
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 Ω speakers for a total supported load of 4 Ω 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.

Product Manual — Doc. 9045H DM NAX™ • 11
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.

12 • DM NAX™ Product Manual — Doc. 9045H
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 DM NAX system.

DM-NAX-16AIN
The Crestron DM NAX™ Audio-over-IP (AoIP) encoder (DM-NAX-16AIN) provides 16 local stereo
audio inputs to a DM NAX Crestron multiroom audio distribution network. It provides 8 digital
inputs comprised of 4 SPDIF TOSLINK® connectors and 4 SPDIF coaxial connectors. Each digital
input supports 2-channel PCM audio. The DM-NAX-16AIN also provides 8 analog stereo inputs.
Inputs 1-4 offer balanced 5-pin terminal block connectors in parallel with unbalanced RCA
connectors, and inputs 5-8 offer RCA connectors.
For installation information, refer to the DM-NAX-16AIN Quick Start.
