Welcome to the iDR-8
The Allen & Heath iDR system is a set of components whose hardware, control and signal processing
flexibility make it well suited to many installed, live sound and special project applications. The 2U
rack or desk mount iDR-8 is the main unit in the iDR system having all the DSP (digital signal
processing) power needed for 16 input and 16 output channels. It has 8 XLR analogue mic/line inputs
and 8 XLR analogue line outputs. You can add a further 8 inputs and/or 8 outputs bringing it up to a
maximum 16x16 matrix by plugging in the iDR-in and/or iDR-out audio expanders. The signal can be
routed at three key points, the input source patch bay, central matrix, and output source patch bay.
Although the iDR does not work with networked audio, the expanders can be located up to 250 metres
away so providing remote analogue audio inputs and outputs connected using CAT5 cables. You can
also daisy chain multiple iDR-8 units in a distributed system. The units are linked using an 8 channel
wide bus which plugs into the digital expander ports. Maximum matrix at any unit is 16x16 which
includes the interconnecting bus. Several iDR-8 units can be linked in this way, but you can have only
one iDR-in and one iDR-out expander per system. This is described later.
A stereo audio monitor is included. This has both input and output TRS jacks so that the monitor can
‘ripple through’ chained iDR units. It also feeds a front panel headphones socket for local monitoring
of any point in the audio signal path. The monitor can access the input and output channels so that
they can be used with the matrix. For example, you can achieve a 10x10 matrix from an unexpanded
iDR-8. A built-in signal/noise generator provides a further source which can be routed to the input
channels for test and line up purposes.
There are many operator control possibilities. You can configure the 16 front panel keys and 32 3colour LEDs, and use the DR-Link port to add up to 3 iDR-switch units for up to 72 additional switch
closure and 48 open-collector logic outputs. In addition you can choose two of the following: MIDI, the
Sys-Net serial port to interface with third party remote controllers, RS232 for modem communication,
and the PL-Anet serial port for setting up a network of Allen & Heath PL wall plates and controllers.
The iDR-8 features networked control. It is configured using the iDR System Manager software via an
Ethernet port either connected directly to the installer’s PC, or over a TCP/IP network. Once configured
it runs stand alone using its built-in iDR Unit software with stored settings. iDR units can also be
operated from networked PC workstations running PL Client software configured as ‘virtual’ wall plates
by the installer using PL Designer software. An RS232 modem port lets the installer remotely
interrogate units. A front panel RS232 port allows easy operating code update.
The iDR system offers tremendous flexibility. The way the system is set up is stored in patches. Up to
99 patches can be programmed. You can decide which parameters are affected by each. To make
best use of this it is important that you plan your installation carefully before you start. You can try out,
prepare and archive different configurations offline before plugging in. Virtual panels and controllers
are displayed so you can simulate how it will work for real. You can program the unit name, clock and
IP address, and check diagnostic information and audio signal presence using the front panel menus
accessed by removing the face plate. You can also attach your custom label here so that it is
protected when the plate is refitted. For further information on the configuration of the unit please refer
to the Help files which come with the software.

System Processing Overview
The iDR-8 has 8 analogue inputs and 8 analogue outputs. However, it has the onboard processing for
a full 16 input and 16 outputs when operating in normal 48kHz mode. The extra 8 inputs and/or
outputs are available when the iDR-in and/or iDR-out audio expanders are added. Only one of each
may be added. This means that you can create an 8x8, 16x8, 8x16 or 16x16 system to suit your
requirements. The stereo monitor input and output can also be added into the matrix in a nonexpanded iDR-8 to create a 10x10 system. iDR-8 units can be daisy chained together using the 8
channel wide digital expander bus to create even more flexible systems with additional local inputs and
outputs and a maximum 16x16 matrix.
48kHz and 96kHz modes The full 16x16 matrix is available in 48kHz operating mode. The expander
channels are not available when the unit is operated in 96kHz mode. In this mode an 8x8 matrix is
provided.
The 48kHz system architecture illustrating the expanded iDR is shown below:
The 96kHz system architecture is shown below:

comes with the iDR System Manager software.
Physical inputs and outputs These are the
hardware audio connections including XLRs,
digital expanders, headphones and monitor.
Input and output channels
These are
processing channels. The input channels can be
sourced from any physical input. The physical
outputs can be sourced from any output channel.
The input and output channels are interconnected
through the crosspoint matrix. They are routed to
and from the physical connections via the source
patchbays. The iDR-8 has enough processing
built in for 16 input and 16 output channels when
in 48kHz mode.
The iDR-in and iDR-out
expanders simply convert the connected
analogue audio into digital signals to feed the
iDR-8 where they access the 16x16 matrix. The
expanders are not available when in 96kHz mode.
Analog inputs The iDR-8 and iDR-in each have
8 analogue XLR inputs. These feed high grade
balanced mic preamp circuits. They accept a
wide range of microphone and line level signals.
Gain, pad and 48V phantom power switching are
controlled using the iDR System Manager
software so they can be part of the recallable
patch system. There are no trimmers or internal
adjustments needed.
Soft limiter The output of each preamp is fed
through an analogue limiter just before the ADC.
The limiter uses an opto device to prevent
excessively high input signals overloading the
converters and causing harsh distortion.
Threshold is -4dBFS. The limiter can be switched
in or out under software control.
Analog outputs The iDR-8 and iDR-out each
have 8 analogue XLR line outputs. These are
balanced and can produce up to +18dBu
maximum signal level.
ADC and DAC converters These convert the
analogue signals into digital (ADC) and processed
digital signals into analogue (DAC). High grade
24bit converters are used.
iDR-8 User Guide
Expander input and output 8 Channels of audio
is communicated between iDR units using these
RJ45 ports. The digital signals are fed to and from
the associated virtual patchbays. Routing the
signals through the patchbays in this way
provides the flexibility for common sources to be
networked between multiple iDR units using CAT5
cable.
Monitor inputs and outputs A front panel stereo
headphones output is provided. Balanced line
level L and R inputs and outputs are available on
the rear panel. The inputs feed the active monitor
bus and can also be routed into the source
patchbay. The outputs are fed from a patchbay
which gets its source from the active monitor bus
or any output channel.
In this way these
connections can be used either as a monitor
system or as channels in their own right.
Signal generator Provides another selectable
source feeding the input channels through the
patchbay. Variable frequency sine wave, pink
noise, white noise or 1/3 octave band pass noise
can be selected. These can be used for system
line up and testing. The level is controlled using
the fader and mute function.
Source patchbays These connect the physical
inputs and outputs to the channels so providing a
flexible ‘virtual patchbay’ routing system. One
physical input can feed more than one input
channel. One output channel can feed more than
one physical output. Note that, as with any
physical patchbay, you cannot route two sources
into one channel, or two channels into one output.
Mix matrix
This is the routing ‘heart’ of the
system fed by all 16 input channels, and feeding
all 16 output channels. It is known as a 16x16
crosspoint matrix. The signal can be switched or
have its level independently controlled at any
point. It is the matrix which provides the key to
independent multi-source zone routing and level
control.
11
Delay Each input and output channel provides
delay from 0 up to 340ms. It can be adjusted in
ms, metres or feet and has compensation for
temperature.
Metering Full metering is provided from all the
points marked ‘M’ in the diagram. Sidechain level,
gain reduction, and stereo monitor meters are
included.
PEQ The input channels each provide a 4 band
fully parametric equaliser, the output channels an
8 band equaliser. Compared with the graphic EQ
these are by far more powerful and accurate tools
for adjusting frequency response. Selectable
band types include HF shelf, LF shelf, bell, notch,
HPF, LPF and crossover filter type. Variable or
constant Q width can be used. The resulting
response is displayed on a frequency curve.
Pager
Two independent paging systems are
provided.
They are fully configurable with
selectable paging mic, zones affected, and
variable ducker depth. They can be triggered
from any soft switch and use any soft LED for
indication. The switch action can be momentary
or latching.
Gate The input channel noise gate is used to
turn the channel off when its level falls below a
preset ‘threshold’ level. This shuts off unwanted
noise such as ambient background pickup,
equipment hiss and hum and so on. It provides
threshold, depth, hold, attack and release
controls. The sidechain can be switched in for
frequency selective gating.
Compressor
The input channel compressor
controls the dynamics of the signal. It can, for
example, help the intelligibility of the human voice
by reducing the gain of high levels and increasing
the gain of low levels, in effect squashing the
levels into a more manageable range.
The
compressor provides threshold, ratio, hard/soft
knee, makeup gain, attack and release controls.
The sidechain can be switched in for frequency
selective compression such as de-essing or LF
contour.
Ducking Any input can override any combination
of outputs with variable depth, threshold and
release. There are 16 assignable priority levels.
Ducking is useful for overriding background music
during announcements, recorded messages,
jukebox playback and so on.
AMM
The automatic mic mixer is popular in
conference situations where several microphones
can contribute to the mix. Microphones are only
opened when they are being spoken into. The
overall gain is reduced as more microphones are
opened. The amount by which they are reduced
is known as the NOM (number of open mics)
setting. This maintains a more constant level and
helps reduce feedback. The ambient level is the
sum of all the mic channels. Threshold adjusts
the point at which the microphone opens above
the ambient level.
Naming
Each input and output channel, and
input and output fader group can be named with
up to 8 characters for identification in the system.
Sidechain filter This input channel filter can be
switched into the gate and/or compressor so that
the dynamic response is tailored according to
frequency. For example, you can reduce the
‘pumping’ effect of a compressor by slightly
cutting the low frequencies in the sidechain, or
prevent false opening by triggering a noise gate
on the resonant frequency of an instrument using
a bell response sidechain filter. Full type and
parameter control is provided.
Limiter
Each output channel includes a
protection limiter to control the maximum level
allowed at the outputs. This is typically used to
protect loudspeakers and control maximum SPL
listening levels. Threshold, attack and release can
be controlled.
Faders, mute and polarity The input and output
channels each provide a fader, mute switch and
polarity reverse. The fader offers +5dB boost
above the unity gain ‘0’ position. The matrix
provides
variable
level
crosspoints
with
independent fader control.
Groups and stereo linking
Faders can be
grouped so that a master fader takes control of
assigned input or output faders. Channels can be
linked for stereo operation with single fader level
control and linked processing throughout the
audio path.
Active monitor bus Any point in the audio signal
path can be monitored. This is selected manually
or by moving the mouse over an active window.
The monitor can ‘ripple through’ several iDR units.
With no monitor point selected, the signal from the
previous iDR unit is passed through to the output.
This means that one monitor output can be used
to listen to any point in a multiple iDR system.

Earthing
The connection to mains earth (ground) in an audio system is important for two reasons:
Safety - To protect the operator from a high voltage shock associated with the AC mains supply
feeding the system.
Audio Performance - To shield the audio signals from interference pickup and to minimise the effects
of ground loops which result in audible hum and buzz.
WARNING: For safety it is important that all equipment earths are
connected to mains earth so that exposed metal parts are prevented from
carrying high voltage which can injure or even kill the operator. The installation
engineer should check the continuity of the safety earth from all points in the
system including microphone bodies, cables, racks and equipment panels.
Earth is used to shield audio cables from external interference such as the hum fields associated with
power transformers, lighting dimmer buzz, and computer radiation. Problems arise when the signal
sees more than one path to mains earth. An earth loop results causing current to flow between the
different earth paths. This condition is usually detected as mains frequency audible hum or buzz. To
ensure safe and trouble-free operation we recommend the following:
Do not remove the earth connection from any iDR unit mains plug. The chassis of the unit is
connected to mains earth through the power cable to ensure your safety. Audio 0V is connected to the
chassis internally. If problems are encountered with earth loops use ‘ground lift’ switches or adaptors
on connected equipment accordingly, or disconnect the screens from interconnecting audio cables at
one end, usually at the destination.
Use a clean mains supply for the audio system. Ensure the audio mains supply is run separately
from lighting, motor, kitchen equipment and any other potentially noisy mains supplies. Use a mains
filter and surge protector for the audio supply if necessary. Take care to ensure good earthing in
distributed systems such as those with audio units linked over long distances.
Connections and Cables
Use professional quality cables and connectors and check for accurate wiring and reliable solder
joints.
Avoid running audio cables alongside mains, computer or lighting cables or near thyristor dimmer
and power supply units. If unavoidable, cross the cables at right angles or run them in separate
screened trunking to reduce the interference pickup.
Use low impedance sources such as 600Ω or less microphones to reduce susceptibility to
interference. The outputs of the iDR are designed to operate at very low impedance to minimise
interference problems.
Use balanced connections where possible as these provide further immunity by cancelling out
interference that may be picked up on long cable runs. To connect an unbalanced source to a
balanced Mic/Line input link the cold input (XLR pin3) to 0V earth (XLR pin1) at the unit. To connect a
balanced Line output to an unbalanced destination, link the cold output to 0V earth at the iDR unit.
Backup Power Supplies and Safety Standards
The iDR system is designed to conform to internationally accepted safety standards IEC60065 and
UL6500. It uses a built-in mains voltage power unit to supply the various internal power rails. It is
recommended that the iDR system be backed up using a UPS (uninterruptible power supply) in
installations where public safety is at risk. This is a requirement when an alarm or voice evacuation
system is integrated.
Check which safety standards apply to your installation. A backup UPS
supply may be required. The standards may also apply to the grade of cable and
installation methods required.

Accessing the iDR-8 Setup Menus
Before your PC can take control of the iDR-8 you need to set
up its unit name and communication settings. This is done
using a simple front panel menu system. Once communication
is established between the PC and iDR-8 you use the iDR
System Manager software to configure and control the unit.

Navigating the menus Press and hold the MENU key for 2
seconds until ‘***Setup***’ is displayed. Press the U and V
keys to scroll through the available menu options. Each menu
is numbered ‘*N.n’ where ‘N’ is the main menu number, and
‘n’ the sub menu. When you find the menu you want, press
ENTER. Press the U and V keys to change the value. Press
the Z ENTER and Y ESC keys to accept or decline the
changes and navigate through the sub menus. Always press
ENTER to save your changes. When you are finished, press
ESC to exit the menus.
Changing the Unit Name
*** Setup ***
*4 Unit Name
The iDR-8 is identified to the PC or network by its unit name.
This name is displayed in the list of available units when you
open a new iDR System Manager session.
To change the unit name select menu item *4 Unit Name.
Scroll through each character using the Z ENTER and Y ESC
keys, and change the value using the U and V keys. The
name can have up to 16 characters.
Checking the Current Settings and Status
Select menu *8 Diagnostics. Scroll through the various sub
menus to view the settings.
*** Setup ***
*8 Diagnostics
Menu *8.1 and 8.2* display the last current IP address and
Subnet Mask. Make a note of these if you need to restore them
later. Note that the address shown is likely to be temporary if
the unit is working with a DHCP server.
The ‘Num Connects’ item displays the number of connections
active via the NETWORK port.
For example, an iDR-8
connected to a network with two PCs both running an active
session of iDR System Manager would report 2 connections. It
is a useful way of checking to see if the unit is being accessed.
The other information displayed includes the sampling rate,
either 48 or 96kHz, which audio expanders are connected, and
the number of remote devices connected to the PL-Anet port.
Rebooting the iDR-8
It is necessary to reboot the iDR-8 if you make changes to the
network or PPP settings. You can do this two ways.
To avoid any unexpected audible clicks
or thumps always turn connected power
amplifiers down or off before switching the
iDR-8 or any other signal equipment on or off.
iDR-8 User Guide
Power the unit off, then back on again, or
Press and then release the front panel CODE UPDATE switch.
This takes around a minute as the unit searches but does not
find update code. It reboots after the update search has timed
out. Note that the code is not updated in this case.

Getting Started – Checking the Hardware
The iDR-8 is supplied with its settings pre-configured so that you can turn it on and
immediately get audio passing through it. This can be useful when you are installing a unit
on site and need to carry out initial tests on the hardware before the custom configuration
software is loaded. This can be done without the need to connect your PC and run the iDR
System Manager software. When shipped, the iDR-8 is loaded with the DEFAULT
configuration. The iDR software provided with the unit also includes this configuration file
so that you can load it again later if you want to restore the default settings.

The channel faders default to fully off. The soft keys are
assigned as level up/down selects to move the input and
output channel faders up and down. Press the soft key for the
channel you want. Now use the two middle keys to scroll the
volume up or down. These time out after 2 seconds of
inactivity. You should see the level displayed as a bar and
number on the LCD display.

You can plug your test source such as a music CD into the XLR
inputs, and route the XLR outputs to your system amplifiers.
You should see the source signal displayed on the left hand
side soft LEDs. Note that the input preamp gains default to
0dBu line level sensitivity with pad selected and phantom
power off. To properly test microphone sources you need to
run iDR System Manager software and correctly set the gains.
LEV 100
To get audio to pass through the unit you need to raise both
the input fader and the required output fader. In this default
configuration all inputs are routed through the matrix to all
outputs. You can use one input to test each output by raising
the output levels in turn. Similarly, you can use one output to
test all input sources. The right hand side soft LEDs display
output signal level.
The levels can be adjusted from ‘0’ (off) to ‘100’ (+5dB boost).
To set the fader to its 0dB unity position raise the level bar until
it reads ‘92’. Note that all the channel processing such as
equalisers and compressors is set flat or out. If you set both
the input and output levels to ‘92’ then you should get 0dB
unity gain through the unit.
With the face plate removed you can use the Setup menus to
listen to selected points in the channels using the stereo
monitor and headphones outputs, adjust the time and day
setting, and enter the communication settings ready to connect
your PC.
For information on configuring the system run the iDR System
Manager software and refer to its Help file.

Communicating with the iDR-8
The iDR-8 is configured using a PC running the Allen & Heath
Windows™ iDR System Manager application.
You need to connect your PC to the iDR-8. To get them to
communicate you must first access the front panel Setup
menus and set up a few communications settings. You also
need to set up your PC to work with these settings.
The iDR-8 communicates using well established computer
communication methods. Full details are provided in the next
section. There are two ways to connect your PC to the iDR-8 :
Network Port
This uses a TCP/IP connection over Ethernet. You can connect
direct to the network port on your PC or via a network, using a
standard CAT5 network cable.
Your PC must have a network port or card fitted. Check that a
suitable port is available.
You need to set up a unique IP address for the iDR-8 unit
using the front panel Setup menus. You should check that
your PC uses its own unique but related IP address. This may
involve making changes to your PC LAN network settings. We
advise that you contact your network administrator or IT
manager if you are unsure how to do this.
