DT164-W
The DT164-W is a fixed installation Dante I/O expander for Allen & Heath digital
mixing systems. It provides 16 remote controlled mic/line preamps and 4 XLR
line outputs. It connects to the Dante network over a single Cat5 cable, or two
cables for redundancy.
The DT164-W can be operated freestanding, mounted in a floor pocket, mounted
on a wall, or flush mounted in a wall. Different power options are provided to suit
the application.
⚠This product must be installed by a professional
installer or qualified electrician.
Contents
Check that you have received the following with your DT164-W unit:
•Optional gland module (part number 004-1097) for permanent AC
mains wiring installation.
•Mounting frame (AH11504) for in-wall or wall surface mounting.
•6x M4 6mm T20 screws (AB2921) for mounting the DT164-W to the
mounting frame.
Software and firmware
Visit the Audinate website to learn more about Dante, and download Dante
Controller to route audio and configure devices on a Dante network:
https://www.audinate.com/
Preamp control of the DT164-W by an SQ mixer requires SQ
firmware V1.4 or higher and an SQ Dante card.
Preamp control of the DT164-W by a dLive mixer requires dLive
firmware V1.8 or higher and a dLive M-DL-Dante 64x64 or 128x128
card. Use of the iLive/GLD M-Dante card is not supported.
Check www.allen-heath.com for the latest DT164-W firmware
and instructions on how to update it.

Connection
Redundant mode
Switched mode (daisy chain example)
Switched mode (digital split example)
A maximum of 32 DT Expanders (DT168 or DT164-W) can be
connected on the same Dante network.
Setting clock and patching signals
Use Dante Controller’s Routing tab to patch signals between Dante devices.
When a valid DT164-W socket is routed to a dLive / SQ Dante card, and patched
to an Input channel, the dLive / SQ will present preamp gain, +48V and Pad
controls for the socket.
Use Dante Controller’s Clock Status tab to select the Dante network master. The
DT164-W should always be slave on the Dante network, with the mixer typically
set to “Preferred Master” and “Enable Sync To External”.

Dante Secondary Can be set to Redundant mode or to Switched
mode for connection to multiple devices, for example two mixing consoles. Set
the port mode in Dante Controller.
Dante Primary EtherCon port for connection to the Dante network. The
cable carries the audio signals as well as preamp control data.
Reset Network settings Hold down the recessed switch for 10
seconds to reset the network settings for the DT164-W. This will delete any
static IP address and revert to factory default (DHCP / zero-conf).
DC 12V Input Can be used instead of AC mains to power the unit
where adequate DC distribution is provided in a building. Can also be used as
a backup power supply in case of mains failure.
Mains power input The built-in universal PSU accepts voltages from
100 to 240V AC 50/60Hz. A module with IEC inlet is fitted by default. An
optional module is provided for permanent installation, with knockout holes to
accept a cable gland.
⚠Replacement of the IEC AC inlet module and mains
wiring for permanent installation must be performed by a
qualified electrician. See instructions later in this guide.

Input sockets Balanced XLR mic/line inputs with +48V Phantom Power
indicator. The preamps are built into the DT164-W and their Gain, Pad and
+48V are controlled from the network.
The +48V indicator detects voltage at the socket whether supplied by the
DT164-W or received from an external source.
Output sockets Balanced XLR outputs operating at nominal +4dBu
level.
Vents Ensure good ventilation at the front of the unit. Avoid obstruction of
vents while operating. Avoid dirt or liquid ingress.

Installation –mounting
⚠WARNING
To prevent injury, this apparatus must be securely attached to
the floor/wall in accordance with the installation instructions.
Mounting on a wall Use the mounting frame AH11504 in the orientation
shown below. Fix the frame to the wall using appropriate fixings or screws for
the type of wall, then align the threaded inserts on the sides of the DT164-W
with the frame, and secure the unit in place with the 6x M4 6mmT20 screws
provided.
Flush mounting in a wall Use the mounting frame AH11504 in the
orientation shown below. Align the threaded inserts on the sides of the DT164-
W with the frame, and secure the unit in place with the 6x M4 6mm T20 screws
provided. Connect the power and Cat5 cable/s, then fix the assembly to the
wall using appropriate fixings or screws for the type of wall.
Floor mounting The DT164-W can be mounted in a floor box / stage pocket /
dip trap. It must be installed in accordance with local installation and wiring
regulations. We recommend using the ACE Backstage 174SLBK stage pocket
system for use with the DT164-W.

Other options The DT164-W will fit a 12x12” NEMA Type 1 / IP10 box or
equivalent. A custom mounting frame might be required.
Permanent installation with the gland module
⚠Replacement of the IEC AC inlet module and mains
wiring for permanent installation must be performed by a
qualified electrician and carried out in accordance with
local wiring regulations.
To replace the IEC module:
•Remove the 4 screws using a Torx T8 driver.
•Pull out the module and unplug the harness at the bottom of the
assembly.
•Fit a suitable cable gland or grommet appropriate to the cable wire
size to the gland module plate.
•Run the mains cable through the gland. Minimum cable size 0.75mm2
or 20 AWG.
•Wire the mains cable to the terminal connector on the gland module,
paying attention to polarity and earth grounding as indicated on the
module.
•Securely tighten the cable gland around the cable.
•Re-plug the internal harness into the bottom of the gland module.
•Secure the module to the unit with the 4x T8 screws.
