FAQs
Q: What is the Allen & Heath AHM-64 used for?
A: The AHM-64 is a 64x64 audio matrix processor designed for installed sound systems in corporate, retail, hospitality, education, and event venues. It handles audio distribution, paging, conferencing, speaker processing, and multi-zone control across up to 64 zones.
Q: How many zones does the AHM-64 support?
A: It supports up to 64 configurable processing outputs, each assignable as mono or stereo zones, making it suitable for everything from a single boardroom to a full multi-building campus.
Q: Does the AHM-64 support Dante networking?
A: Yes, with an optional Dante card supporting 64x64 channels at 96kHz with AES67 and DDM compatibility. The built-in SLink port also provides 128x128 channel audio expansion over Cat5e or higher cable.
Q: Does the AHM-64 have acoustic echo cancellation (AEC)?
A: AEC is available as an optional module for the AHM-64, along with Ambient Noise Compensation (ANC), 8 Automatic Mic Mixers (AMMs), and priority ducking for comprehensive conferencing and speech reinforcement control.
Q: Can the AHM-64 be scheduled and automated?
A: Yes. It supports an event scheduler that stores up to 50 individual events with custom names, specific recall times, and recurring weekly or monthly scheduling, making it ideal for multi-use facilities.
Q: How is the AHM-64 controlled?
A: It can be controlled via System Manager software, IP remote controllers (IP1, IP6, IP8), the Custom Control app and editor, TCP control over the RJ45 network port, and up to 32 individual user profiles with password protection and custom permissions.
Q: What audio file formats does the AHM-64 support for playback?
A: It supports stereo and dual mono playback of WAV (16/24-bit, 44.1/48/96kHz), MP3, and FLAC files from approximately 3GB of internal storage.
