Allen & Heath AHM‑32 32×32 Audio Matrix Processor

Overview

The AHM‑32 from Allen & Heath is a 32×32 audio matrix processor — a powerful DSP / routing engine designed for multi‑zone sound distribution, installation audio, paging, conferencing, and venue-wide audio management. It is built for fixed‑install setups (hotels, corporate buildings, schools, theaters, retail, multi-room venues), but flexible enough for complex audio networking and large distributed systems.

It features a mix of local analog I/O (mic/line), configurable processing on all zones, and extensive network/I‑O expansion options — making it a core audio engine for installations requiring many inputs and outputs, DSP processing, and flexible routing.

  Key Features & Capabilities

• 32×32 Processing Matrix — route up to 32 inputs to 32 outputs with full processing per zone/output
• 12×12 Local Analog I/O — includes 12 mic/line inputs and 12 relay‑protected line outputs (on balanced Phoenix connectors), allowing use even without external I/O expanders
• I/O Networking / Expansion Port — supports optional network or expansion cards (e.g. Dante, SLink, MADI, Waves), enabling up to 128×128 channel audio networking/expansion
• Configurable Zone Outputs — up to 32 mono zones or 16 stereo zones / speaker zones, each configurable independently
• Full DSP per Input & Zone:
• 8‑band parametric PEQ (equalization)
• Dynamics processing (gate/comp/limiter as needed)
• Delay for input or zone channels
• Speaker processing per zone: crossover filters, delay, limiter, EQ, all‑pass filters — useful for multi‑way speaker setups
• Sound Management & Advanced Tools:
• 4× Automatic Mic Mixers — to manage multiple mic inputs intelligently (suitable for meetings, conferences)
• Ambient Noise Compensation (ANC) — helps maintain consistent levels in varying ambient noise environments
• Priority Ducking — automatic lowering of background audio when paging or announcements occur
• (Optional) Acoustic Echo Cancellation (AEC) and Feedback Suppression — helpful for conferencing / video‑conferencing / live speech installations (when the AEC/FBS module is installed)
• High‑Performance Core — 96 kHz FPGA‑based processing for low latency and high audio fidelity
• Flexible Control & Integration:
• Front‑panel display + 8 programmable SoftKeys for quick control (volume, source select, preset recall)
• Compatibility with remote controllers (e.g. IP1, IP6, IP8) — allows wall‑mounted or desk‑mounted remote volume / source / zone control
• 2×2 local GPIO plus network‑accessible GPIO, plus support for TCP/IP control — enables integration with external control systems (e.g. automation, building control, third‑party control systems)
• Drivers available for common control platforms (e.g. Crestron, AMX, Extron) — useful for professional AV installations
• Support for multiple user profiles (up to 16) and event scheduling — suited for environments where different zones/users need customized control or time‑based audio behavior
• Integrated stereo playback (for background music, announcements, etc.)
• Scalable & Expandable — thanks to the network I/O port and optional expansion cards, the AHM‑32 can be scaled up considerably for large venues, distributed audio networks, or complex multi-room systems
