About Allen & Heath AHM Matrix Processor

Take your audio management to the next level with the AHM-16 16x16 Digital Audio Matrix Processor, a high-performance device designed for optimal sound distribution and control in various environments. This processor is perfect for single room applications or smaller multi-room settings such as bars, restaurants, retail shops, and school halls.

The AHM-16 boasts a 16x16 processing matrix, offering flexible routing with configurable processing on all 16 outputs. It also features an 8x8 local analogue I/O, comprising 8x mic/line inputs and 8x relay-protected line outputs on Phoenix connectors.

This audio matrix processor is equipped with advanced sound management tools, including an Automatic Mic Mixer, Ambient Noise Compensation (ANC), Priority Ducking, and an 8-band PEQ. These features, along with dynamics and delay on every input and zone, ensure superior sound quality and control.

The AHM-16 also offers speaker processing with a crossover filter, delay, limiter, and PEQ. This hardware is always in control, thanks to remote controllers, GPIO, and 3rd party integration. The front panel screen and 4x programmable SoftKeys provide intuitive volume control, source selection, preset recall, and more.

Designed for diverse applications, the AHM-16 is ideal for corporate, hospitality, education, event and multi-purpose venues, retail, theatres, cruise ships, and sports venues. It is complemented by an extended ecosystem of remote audio expanders, remote controllers, interfaces, apps, and software.

The AHM-16 processor also integrates seamlessly with third-party devices over GPIO, TCP/IP, or industry-standard control systems. The Custom Control editor and app from Allen & Heath offer more control options and tailored user interfaces for multiple users and device types, with kiosk and BYOD capability.

This 1u rack-mountable digital matrix processor operates at a 96kHz sample rate and employs FPGA technology for digital signal processing. It offers 16 input channels and 16 output channels, all independently assigned. The system latency from analogue input to output does not exceed 1ms, ensuring real-time audio processing.

The AHM-16 is more than just a processor; it's a comprehensive solution for all your audio management needs. With its robust features and flexible functionality, it's the perfect addition to any sound system.
