Allen & Heath IDR-4 Digital Audio Mix Processor

Allen & Heath iDR-4 Digital Audio Mix Processor

Also available : iDR-In & iDR-Out Expanders, please select.

The 1U rack or desk mount iDR-4 is the main unit in the iDR system having all the DSP (digital signal processing) power needed for 16 input and 16 output channels. The iDR-4 has a total of 6 balanced audio inputs including 2 XLR analogue mic/line and 4 TRS jack line inputs. It has 6 balanced audio outputs including 4 XLR analogue land 2 TRS jack line outputs. You can add a further 8 inputs and/or 8 outputs bringing it up to a maximum 14×14 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 crosspoint matrix, and output source patch bay.

Features : 

• iDR-4 main processing unit 1U, 2 mic/line in, 4 line in, 6 line out audio mix processor with 16×16 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,  ED indicator and logic output control. Connects via the PL-Anet serial port.
• 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 iDRswitch 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 16×16 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 16×16 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.
