Rack Mounting Safety Precautions
Elevated Operating Ambient Temperature: If installed in a closed or
multi-unit rack assembly, the operating ambient temperature of the
rack environment may be greater than room ambient temperature.
Therefore, consideration should be given to installing the equipment in
an environment compatible with the maximum ambient temperature
(Tma) specified by the manufacturer.
Reduced Airflow: Installation of the equipment in a rack should be such
that the amount of airflow required for safe operation of the equipment
is not compromised.
Mechanical Loading: Mounting of the equipment in the rack should be
such that a hazardous condition is not achieved due to uneven
mechanical loading.
Circuit Overloading: Consideration should be given to the connection of
the equipment to the supply circuit and the effect that overloading of
the circuits might have on overcurrent protection and supply wiring.
Appropriate consideration of equipment nameplate ratings should be
used when addressing this concern.
Reliable Earthing: Reliable earthing of rack-mounted equipment should
be maintained. Particular attention should be given to supply
connections other than direct connections to the branch circuit (e.g., use
of power strips).
Connect the Device
Make the necessary connections as called out in the following
illustration. Connect power last.
CAUTION:
lKeep the device unplugged until all of the input, network, output,
and speaker wiring is complete.
lCheck the speaker cables for shorts and frayed wiring around the
SPEAKER OUTPUTS connectors.
NOTE:
lEnsure that the unit is properly grounded by connecting the
chassis ground lug to an earth ground (building steel).
lTo prevent overheating, do not operate this product in an area
that exceeds the environmental temperature range listed in the
product specifications.
lDo not bundle power cords together with connection cables.
Doing so can result in noise.

Refer to the following illustration when connecting digital audio sources.
NOTE: Only 2-channel PCM digital audio is supported at the digital
inputs.
Analog Inputs
Refer to the following illustration when connecting analog audio sources.
Speaker Connections
The speaker outputs can be wired conventionally or bridged together to
deliver higher output power.
NOTE: The Line Outputs 1-4 mirror their respective Speaker Outputs
1-4. These outputs can feed another amplifier or an active
subwoofer.
Conventional Wiring
Connect speakers to the DM-NAX-8ZSA as shown in the following
illustration.

Bridged Wiring
Connect speaker outputs as shown in the following illustration to deliver
more power to the speakers (8 ohm speakers only).
NOTE:
lBefore wiring the speakers for bridging, ensure that the device is
configured for bridging using web UI, Crestron Home™ software,
or a Crestron SIMPL program running on a control system.
lBridging can only be done between a left and a right output
within the labeled zone.

Apple® AirPlay® Setup
The DM-NAX-8ZSA supports AirPlay 2 and requires iOS11.4 or later.
AirPlay can be enabled on any of the built-in media players on the DM-
NAX-8ZSA.
To stream media from an iOS device to a speaker zone in your
distributed audio system:
1. Ensure that the iOS device and DM-NAX-8ZSA are on the same
network.
2. On the DM-NAX-8ZSA, enable AirPlay for the built-in media player
you would like to stream to, either using the web UI or programming.
For more information, refer to the DM NAX™ Product Manual (Doc.
9045).
NOTE: If the control/media and Audio-over-IP network traffic is
isolated between two network ports on the DM-NAX-8ZSA,
AirPlay will use the port specified for the Control/Media traffic.
3. On your iOS device:
a. Enable AirPlay
b. From the list of available AirPlay destinations, select the DM-
NAX-8ZSA zone you would like to stream to.
The media player will play back audio to the selected zone(s).
NOTE: By default, media players 1 - 8 route the audio signals to their
respectively numbered speaker zones 1 - 8. If the user has not
specified the speaker zone when Airplay streaming begins, the
media player will automatically route to its default speaker zone.
For example, the audio from the media player 5 will be routed to
speaker zone 5.
After the AirPlay streaming begins, you will be able to control the
volume of the streaming DM-NAX-8ZSA speaker zones directly from
your iOS device.
