iDR-4 User Guide 7

Main Features

• iDR-4 main processing unit 1U, 2 mic/line in, 4

line in, 6 line out audio mix processor with 16x16

channel matrix. The heart of the iDR system, it

features 2 24bit Motorola DSPs.

• Daisy chain iDR-4 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 14. 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 14. 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. Also provides protection for

code update.

• XLR mic/line inputs Electronically balanced, pin

2 hot, for microphone or line level equipment.

Soft control of gain, pad switch and 20V phantom

power. No internal adjustments needed.

• XLR line outputs Electronically balanced, pin 2

hot, 0dBu with +18dB headroom.

• TRS line inputs and outputs Electronically

balanced, tip hot, ring cold, 0dBu with +18dB

headroom.

• Stereo audio monitor uses line in/out TRS jacks

5 and 6. Can monitor any point in the audio chain

using manual or mouse selection.

• Network port to connect to a PC or network for

control using the iDR System Manager, PL Client

software, Telnet, TCP/IP, remote access and

more.

• RS232 port for connection to a modem for

remote system interrogation.

• SysNet port a second RS232 port to interface

with third party touch screens and other remote

controllers running the proprietary Allen & Heath

SysNet protocol. It is also used when updating

the iDR operating code via a PC serial com port.

• 8 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.

• 16 Front panel 3-colour soft LEDs can be

assigned by the installer as signal meters, mute,

level triggered 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. The software can

be password protected.

• 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.

• 48kHz operation The iDR-4 has processing for a

full 16x16 matrix running at 48kHz. An upgrade to

96kHz may become available in the future.

• 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 for display on the unit

LCD, and for scheduled event patch recalls using

the internal iDR-4 clock.

• Naming Input channels, output channels, groups

and PL devices can be named.

• Channel processing Includes 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.
