Allen & Heath AHM-64 Audio Matrix Processor

Allen & Heath AHM-64 Audio Matrix Processor

Allen & Heath AHM-64 is a 64 × 64 audio matrix processor. It distributes and processes sound across multiple zones in a building or event venue.

The 96 kHz FPGA system allocates processing channels flexibly to mono or stereo zones. Integrated analogue microphone/line inputs and balanced line outputs use Phoenix terminal connectors.

Input and zone EQ, compression and delay adapt signals to the room. Automatic microphone mixers manage multiple microphones, while priority ducking and ambient noise compensation handle speech and background music levels.

SLink connects compatible Allen & Heath Everything I/O expanders. An optional network card slot accommodates Dante. Dante, acoustic echo cancellation (AEC) and feedback suppression (FBS) require separately purchased cards or a processing module.

System Manager configures the system. Custom Control provides a tailored user interface, with IP-series controllers, GPIO and TCP/IP offering additional control options. The processor occupies 2U in a 19-inch equipment rack.

Main Features

• 64 mono or 32 stereo zones divide the system according to room requirements.
• Eight automatic microphone mixers support multi-microphone speech applications.
• 8-band parametric EQ, compressors and delay process inputs and zones.
• 28-band graphic EQ provides additional zone frequency correction.
• Ambient noise compensation and priority ducking adapt sound levels to changing conditions.
• 2, 3 or 4-way speaker processing includes crossover filters, 4-band EQ, limiting and delay.
• SLink and an optional network card expand the analogue and network audio system.
• Custom Control and up to 96 IP1, IP6 or IP8 controllers provide multiple control positions.
• Internal audio playback and scheduled events support background music and automatic actions.
