iDR-8 User Guide 7
Main Features
• iDR-8 main processing unit 2U, 8 mic/line in, 8
line out audio mix processor with 16x16 channel
matrix. The heart of the iDR system, it features 2
24bit Motorola DSPs.
• Daisy chain iDR-8 units Any number may be
interconnected via the 8 channel digital bus using
CAT5 cable. Many possibilities for flexible sound
system solutions.
• iDR-in 1U, 8 mic/line input expander unit.
Expands the number of inputs to 16. Can be up
to 250 metres away for remote audio. Uses CAT5
digital link. One input expander per iDR system.
• iDR-out 1U, 8 line output expander unit.
Expands the number of outputs to 16. Can be up
to 250 metres away for remote audio. Uses CAT5
digital link. One output expander per iDR system.
• iDR-switch 1U add-on unit providing 24 contact
closure switch inputs and 16 open collector logic
outputs. Up to 3 units may be daisy chained for a
maximum 72 switch and 48 logic outputs. Each
unit can be separated by up to 250 metres.
Connects via the DR-Link serial port.
• PL wall plates and remotes The Allen & Heath
range of optional wall plates and controllers for
remote switch, rotary encoder, infra-red, fader,
LED indicator and logic output control. Connects
via the PL-Anet serial port.
• Desk top or 19” rack mounting Rubber feet and
removable rack ears provided.
• Universal mains power input automatically
detects worldwide voltage from 100V to 240V AC.
• Removable face plate for accessing front panel
setup menu system, RS232 connector and status
indicators. Also provides a protected custom
label facility.
• XLR mic/line inputs Electronically balanced, pin
2 hot, for microphone or line level equipment.
Soft control of gain, pad switch and 48V phantom
power. No internal adjustments needed. Pre ADC
soft limiter to prevent digital distortion.
• XLR line outputs Electronically balanced, pin 2
hot, 0dBu with +18dB headroom.
• Stereo audio monitor with front panel
headphones socket and rear panel TRS jacks.
Can monitor any point in the audio chain using
manual or mouse selection. Can be used with the
audio matrix as two additional channels, for
example providing a 10x10 matrix from an
unexpanded iDR-8.
• Network port for connection to a PC or network
with control using the iDR System Manager or PL
Client software.
• RS232 ports on front and rear for connection to
a PC for code update and to a modem for remote
system interrogation.
• SysNet port for control by third part touch
screens and other remote controllers.
• MIDI port IN, OUT and THRU sockets provided
for remote control using show controllers and
other MIDI equipment.
• 16 Front panel soft keys can be assigned by the
installer as level, mute or patch recall with different
types of press action. Similar applies to the iDR-
switch functions.
• 32 Front panel 3-colour soft LEDs can be
assigned by the installer as signal meters, mute or
patch related indicators.
• Front panel LCD display A 16 character 2 line
LCD can display combinations of clock, patch
name, unit name and user defined text. This can
be linked to the patches.
• iDR System Manager software for system setup.
Once configured the PC can be removed and the
system operated stand alone.
• PL Designer and Client software for creation of
‘virtual’ wall plates and controllers that can be run
from networked PC workstations. Operator
control can be restricted by the installer.
• Powerful fixed architecture with full processing
on all 16 input and output channels. Familiar GUI
makes setup and control an easy task.
• 48/96kHz operating modes The iDR-8 has
processing for the full 16x16 matrix in 48kHz
mode, and 8x8 in 96kHz mode.
• Patchbays and crosspoint matrix The input
source patchbay selects any physical input to any
input channel. The output patchbay selects any
output channel to any physical output. The 16x16
matrix allows independent level control at each
crosspoint.
• Channel stereo linking and grouping Input and
output channels can be linked for true stereo
operation, and grouped for master fader control.
• Configurations can be named, archived and
opened using PC files. These store the system
setup parameters such as communication
options, names, stereo linking, scheduled events
and set of patches.
• Patches Up to 99 patches can be created,
named and stored within the configuration file. A
patch can work with any number of selected
parameters including signal processing, soft key
and LED settings. This provides a unique
flexibility in setting up complex changes with
simple operator control.
• Time and day of week can be displayed on the
unit LCD, and is also used for scheduled event
patch recalls.
• Naming Input channels, output channels and
groups can be named.
• Channel processing The channels have full
processing including faders, mute, polarity
reverse, delay, parametric EQ, crossover filters
noise gates, compressors and limiters.
• Ducking, AMM and paging System functions
include a 16 priority level ducker, automatic mic
mixer and two independent pagers.
• Signal generator provides sine wave, white, pink
and band pass noise signals for system line up
and test.
