iDR-in and iDR-out are add-on audio expander units for the Allen & Heath iDR-4 and iDR-8 audio mix processors.
They provide additional analogue audio inputs and outputs to add to those on the main unit. The iDR-in has 8 mic/line
inputs, the iDR-out has 8 line outputs. One or both may be connected to the iDR. Only one of each may be added to
the iDR system bringing it up to a maximum 16x16 audio matrix. These units do not have any processing built in. They
simply convert between analogue and digital audio to work with an 8 channel wide digital bus which feeds the main
unit via a CAT5 STP cable. The iDR-in features high grade mic/line preamps with PC configured gain, pad and
phantom power switching, and a built-in soft clip limiter. The iDR-out provides electronically balanced differential
outputs. The processing is available on the main iDR-4 or iDR-8 unit which features the full 16x16 DSP matrix. Both
units have 8 front panel LEDs in addition to the 3 status indicators. These are 3-colour soft LEDs which can be
assigned as audio meters, mute indicators or patch related indicators. They are programmed in the usual way using
the iDR System Manager software. Control of the expanders is via the DR-Link port using a CAT5 STP cable. This
means that two CAT5 cables are required to interconnect an expander to the main unit. Maximum distance between
the units is 250 metres. Local mains power is required.
This product complies with the European Electromagnetic
Compatibility directives 89/336/EEC & 92/31/EEC and the
European Low Voltage Directives 73/23/EEC & 93/68/EEC.
NOTE: Do not remove the cover of the unit. There are no user serviceable
parts inside. Any changes or modifications to the equipment not approved by
Allen & Heath could void the compliance of the equipment and therefore the
users authority to operate it.

The iDR-in and iDR-out expanders can be rack mounted or free standing. There are no
user controls on the front panel, only the status and assignable LEDs. Allow a minimum of
75mm clearance behind the unit for the connectors and cables. Ensure adequate
ventilation to the side of and behind the unit.
It is shipped with its rack ears fitted and its feet removed ready to be mounted in a standard
19” equipment rack. 1U rack space is required. For desk mount operation remove the two
rack ears using a Torx (star head) T10 screwdriver. Fit the four plastic feet provided by
pressing them into the underside.

Make sure you have read the Important Safety
Instructions printed earlier. Also check that your local
mains supply is compatible with that printed on the rear
panel of the unit. Ensure that the correct mains lead with
moulded plug and IEC connector has been supplied. For
your own safety and optimum performance make sure the
system is correctly grounded.

To avoid any unexpected audible clicks or thumps
always turn connected power amplifiers down or off before
switching the iDR or any other signal equipment on or off.
Turning the expander on or off
lock
link
power
First make sure
the unit is correctly plugged up and connected to the iDR-4(8).
This is described below. Turn the unit on by pressing the rear
panel power ON/OFF switch. The power LED lights up. The
link LED lights if the DR-Link connection is established with the
iDR-4(8). The lock LED lights once the link is established and
audio is correctly communicated with the iDR-4(8). The iDR
System Manager detects the presence of the expander.
If one or more of the LEDs do not light then check that the
cables are correctly fitted and the iDR-4(8) is functioning
normally.

Checking for expanders You can use the front
panel iDR-4(8) Setup menus to check if any expanders are
connected and recognised. This is useful when the expanders
are located far away from the main unit. With the face plate
removed access menu *8 Diagnostics and scroll to Audio Exp.
Refer to the iDR-4 user guide AP5230 or iDR-8 user guide
AP4530 for further details.

Connecting to the iDR-4(8) You can connect
either or both expanders according to the requirements of your
application. The iDR-in AUDIO OUT connects to the iDR-4(8)
AUDIO IN. The iDR-out AUDIO IN connects to the iDR-4(8)
AUDIO OUT. Ensure that the expander DR-Link IN connects to
DR-Link on the iDR-4(8) it is associated with.
If both
expanders are used with the same iDR-4(8) then daisy chain
from DR-Link OUT on one to DR-Link IN on the other. DR-Link
can also be daisy chained from or to iDR-switch units if you
are using them as well.

Note the connection of DR-Link which is daisy chained from
one unit to the next. If an iDR-switch unit is also fitted then
daisy chain DR-Link from the last expander to the switch box.
Make sure you plug into the correct DR-Link socket.

Use CAT5 STP cable. A pair of standard 2 metre cables is
provided with each expander. Maximum cable length is 250

This diagram
shows an iDR system with two iDR-8 units and both expanders
fitted. A system could also be created with iDR-4 units or a mix
of iDR4 and iDR-8 units. DR-Link is only required to connect to
the expanders, not between the main units. Make sure you
connect DR-Link to the iDR associated with each expander.
Make sure you plug into the correct DR-Link socket. In this
case do not daisy chain DR-Link from one expander to the
other.
Use CAT5 STP cable. Maximum cable length is 250 metres.
Maximum audio matrix is 16x16. The audio link cable carries 8
channels. This can provide a distributed system with 8
common channels and 8 local channels at each unit.
