Description
AHM-64 is a powerful 64x64 Audio Matrix Processor supported by a comprehensive ecosystem of scalable I/O, control and Dante solutions. Designed to excel in corporate, retail, hospitality and education environments, AHM-64 allows integrators to quickly create systems that build from a single boardroom to a complete campus.

Sound management tools:
Everything I/O
AHM-64's SLink port allows plug 'n play connection to up to 8 remote expanders from Allen + Heath's extensive Everything I/O range, which includes wall mount, rack and portable options. With up to 268 routable system inputs and outputs, AHM-64 can cater for projects ranging from a single room to large, distributed spaces.
An AHM-64 system can be controlled using a range of remote controllers, GPIO and 3rd party devices. With up to 96 IP remote controllers over a standard TCP/IP network, every room can enjoy local volume control, source select and preset recall.
Custom Control App
Designing the perfect user interface for each type of user has never been so easy. Custom Control is a customizable, cross-platform control app, providing elegant, bespoke control over an AHM-64 system.
System Manager Software
Intuitive AHM System Manager software and AHM-64's flexible architecture allow rapid configuration, with no certified programming training required. AHM-64 strikes a balance between the simplicity and set latency of fixed architecture, and the flexibility normally reserved for open architecture platforms, allowing it to handle sound management, paging, audio distribution, conferencing and speaker processing roles.
AHM-64 deploys next-generation FPGA technology and 96kHz sample rate, bringing acclaimed Allen + Heath sound quality and sub-millisecond latency to installation. The audio engine has the power to deliver far more processing than the usual open architecture platforms, including 8-band PEQ, gate, compressor and delay on all input channels, and 8-band PEQ / 30-band GEQ, compressor, ANC, source selector, limiter and delay on all zone outputs.
Dante Spoken Here
A 64x64 channel Dante option card allows AHM-64 to seamlessly connect to amplifiers, microphones and other devices on a Dante network, including the DT164-W and DT168 Dante I/O expanders. The card can be switched between 96kHz and 48kHz to accommodate Dante networks running at either sample rate.
Waves Integration
The SQ Waves option card provides AHM-64 unit with a 64×64, 96kHz or 48kHz interface to a Waves SoundGrid network using the I/O Port. Installers can now fit the Waves card to AHM-64 for Waves plugin processing, multitrack recording (at 96kHz or 48kHz) and audio distribution applications.
