General precautions
•Protect the equipment from damage through liquid or dust contamination. Cover the expander
when it is not being used for a long period.
•If the equipment has been stored in sub-zero temperatures allow time for it to reach normal
operating temperature before use at the venue. Recommended operating temperature is 0 to 35
degrees Celsius.
•Avoid using the equipment in extreme heat and direct sunlight. Make sure the ventilation slots are
not obstructed and that there is adequate air movement around the equipment.
•Clean the equipment with a soft brush and dry lint-free cloth. Do not use chemicals, abrasives or
solvents.
•It is recommended that servicing is carried out only by an authorised Allen & Heath agent. Contact
details for your local distributor can be found on the Allen & Heath website. Allen & Heath do not

Introduction
The DX32 is a rack I/O Expander for Allen & Heath 96kHz digital mixing systems. It provides 4 slots for 8ch
analogue or digital I/O cards, in any combination, and a modular power supply with optional redundancy.
It connects to the mixing system over a single Cat cable, or two cables (to compatible hardware) for
redundancy.

1. Installing the Expander
1.1 Free standing
The Expander can be operated as a freestanding unit for shelf or floor use. It can be operated horizontally
with the connectors facing upward or sideward. Check that its plastic feet are fitted in the intended position.
Ensure adequate air flow around the unit. It must not be covered in any way. Always
stand the unit on a firm flat surface away from any soft furnishings or carpet.
1.2 Rack mounting and flight casing
The DX32 is designed as a 19 inch rack mount unit and occupies 4U of rack space. The plastic feet may
need to be removed before rack mounting; retain them for future use.
For rental, touring and other portable use, we recommend that you use a professional grade flight case.
Ensure natural convection of airflow around the unit by allowing good ventilation
below, in front of and behind the unit. Rack equipment known to produce a
significant amount of heat should not be mounted directly below the unit. Forced
convection by means of a rack mounted fan-tray may be desirable in situations
where space is restricted and the ambient air temperature is high.
1.3 Rack ears
The rack ears can be detached for shelf or floor operation, and can be mounted facing either the front or
rear panel to suit the application. They are secured to the sides of the Expander with 3 screws each as
indicated below. Use a Pozidrive screwdriver to remove or reposition the rack ears.

2. Front Panel
I/O modules –4x slots for fitting 8ch analogue or digital I/O modules. To fit
a module, switch the expander off, remove the blank panel by loosening the 2 thumb
screws, slide the module into the slot and press it firmly into the mating connector,
then secure it by tightening the thumb screws.
Use the mixer I/O screen or AHM System Manager Assign screen to patch signals
from or to the DX expander.
Status indicators –Power ON indicators for the 2 power supplies. The
Ready indicator lights up when the output sockets are ready to pass audio after power
up.
DX links –Dual redundant EtherCon ports for connection to the mixing
system over Fast Ethernet (IEEE 802.3 Layer 2 compliant). A single Cat5e (or higher)
cable carries 32x32 channels of 96kHz audio and control data. Use two cables for
redundant connection to compatible hardware e.g. dLive S Class or DX Link card.
Power Supply –Hot swappable power supply with mains IEC socket and
On/Off rocker switch. To remove or replace, loosen the 4 screws indicated below and
slide the PSU out of the slot.
DX Expanders ship with one PSU fitted. A second PSU can be fitted for redundancy
(part number MPS-16). Remove the 4 screws securing the blank panel using a star
Torx T8 screwdriver, slide the PSU into the slot, and tighten the 4 screws indicated
above. The Expander will automatically switch between the supplies without
interruption to the audio should one fail.
Heed the safety warnings printed on the panel.
A plastic P-clip cable clamp is provided to secure the mains cable. Slot the cable in
or lock it in place using a star Torx T20 screwdriver to refit the clamp around the cable.

4. I/O Modules
M-AIN - Recallable preamps for balanced or unbalanced microphone and line level signals. Gain, Pad
and 48V are digitally controlled within the preamp. The PP indicator lights up when phantom power voltage
is detected at the socket, whether internally or externally sourced.
M-AOUT –Line level, balanced XLR outputs. Nominal level +4dBu. The outputs are relay protected to
prevent power on or off thumps.
M-DIN –4x stereo AES3 inputs with SRC (32kHz –192kHz sampling rate). Sample Rate Conversion can
be bypassed for each socket (for 96kHz operation only).
M-DOUT –4x stereo AES3 outputs (44.1kHz, 48kHz, 88.2kHz or 96kHz switchable with LED indication of
sample rate).
PRIME INPUT –Next-generation preamp design with DC coupled gain stage and 32bit ADC for class-
leading conversion.
PRIME OUTPUT –Next-generation output design using the very latest 32bit converters and specially
selected op amps for ultra-low noise.

5. Connect and power up
5.1 Connection to the mixing system
Connect the DX Expander to the mixing system. Use two cables for redundancy if required.
Redundant mode –to compatible hardware only
If the firmware in a connected DX Expander is not the same version as that in the
mixing system, then the host mixer or processor will automatically update the DX
firmware during power up. This can take up to 20 seconds. During this time the
Lnk/Err indicators on the DX Expander flash at a fast rate. Once updated normal
flash rate is restored.
5.2 Cables
Use Cat5e or higher STP cables with a maximum cable length of 100m per connection.
Allen & Heath can provide a number of Cat5e and Cat6 cables suitable for use with the GX Expander:
AH9997 2m CAT5e cable with Neutrik EtherCon locking connectors
AH10887 100m drum of CAT6 cable with Neutrik EtherCon locking connectors
AH10886 80m drum of CAT6 cable with Neutrik EtherCon locking connectors
AH10885 50m drum of CAT6 cable with Neutrik EtherCon locking connectors
AH10884 20m drum of CAT6 cable with Neutrik EtherCon locking connectors
