Allen & Heath AHM-64 2RU 64x64 Audio Matrix Processor w/12x12 Local Analog I/O

AHM-64 is an audio matrix processor for sound management and installation. It is designed for audio distribution, paging, conferencing and speaker processing in a multitude of environments including corporate, hospitality, education, event and multi-purpose venues, retail, theatres, cruise ships and sports venues.The AHM-64 processor is complemented by an extended ecosystem of remote audio expanders, remote controllers, interfaces, apps and software. A family of portable, rack-mountable or wall-mount audio expanders is available with a choice of proprietary point-to-point Layer-2 or Dante transport protocols.Sound Management• 8x Automatic Mic Mixers• ANC (Ambient Noise Compensation)• Priority ducking• 8-band PEQ, dynamics and delay on every input and zone• Speaker processing with x-over filter, delay, limiter and PEQ• Processing expansion moduleThe unit shall be a 2u rack-mountable digital matrix processor, capable of 64 input channels and 64 output channels, all independently assigned. The unit shall operate at 96kHz sample rate and employ FPGA technology for digital signal processing. The system latency from analogue input to output shall not exceed 1ms. All input channels shall be configurable mono/stereo and have access to any local or remote input.Output channels shall be configurable as mono/stereo zones or as speaker processing outputs with 2, 3 or 4-way Crossovers, allowing up to 64 mono zones / 32 stereo zones, or any combination of zones and speaker processing outputs not exceeding 64 total channels. All input channels shall provide the following processing: Trim, Polarity, Gate, Insert point, 8-band Parametric EQ, Compressor, Delay and Automatic Mic Mixing (AMM).All zones shall provide the following processing: Source Selector, Insert point, 8-band Parametric EQ, 28-band GEQ, Compressor, Delay, Ambient Noise Compensation (ANC) and Limiter. All speaker processing outputs shall provide the following processing: Crossover filters with selectable filter type and slope, PEQ, Delay and Limiter.All output channels shall be routable to any local or remote output. The 8-band Parametric EQ shall provide Bell, Constant Q, Shelving, LPF, HPF and Notch filter types selectable per band.The unit shall have 12 balanced inputs on pluggable Phoenix terminal blocks. Each input shall have independent gain control with +60dB of gain, a -20dB active PAD and +48V phantom power. The unit shall have 12 balanced outputs on pluggable Phoenix terminal blocks with a nominal level of +4dBu. The routing matrix mixer shall be capable of mixing all inputs to all zones, as well as all zones to other zones.The unit shall provide Automatic Mic Mixing (AMM) of up to 64 microphone sources into 1, 2 ,4 or 8 zones. The AMM shall be capable of running in classic gain sharing mode or optionally as a NOM (Number of Open Microphones) algorithm. The unit shall offer a slot for optional processing modules including Acoustic Echo Cancellation.Playback of stereo or dual mono .WAV, MP3 and FLAC files shall be supported, with internal storage for the audio files.There shall be a local SLink Ethernet audio expansion port, supporting multiple Audio-over-Ethernet protocols and providing access to up to 128x128 I/O, and allowing remote connection and preamp control of Allen & Heath audio expanders, connected via a single Cat5e or higher cable.An RJ45 Control Network port shall be provided on the rear of the unit for connection to System Manager software, IP remote controllers, Custom Control app and TCP control.One 128x128 I/O port for optional digital interface modules shall be provided. The Dante optional module shall provide a minimum of 64x64 I/O at 96kHz, and be compliant with AES67 and Dante Domain Manager.The unit shall provide the facility to save 500 presets. The presets shall be nameable and a descriptive text entry per preset provided. A crossfade of up to 20 seconds shall be available to apply to any combination of Inputs, Zones, Groups, Input/Zone Crosspoints and Zone/Zone Crosspoints.The unit shall provide the facility to save 50 events. The events shall be nameable and should allow for the scheduled recall of presets at a specified time on specific days, or every day, with the option for the event to be triggered repeatedly or just once.The unit shall allow the creation and storage of up to 32 user profiles, each with an editable name, password and permission settings.The unit shall allow the connection of two general purpose inputs, and two general purpose relay outputs, via pluggable Phoenix connectors on the rear of the chassis. Each input connector shall allow analogue control of Mutes, Levels, Preset Recall, Custom MIDI and Audio Playback via a 0-10V control signal. Output 1 shall support normally closed and normally open operation, and output 2 shall support normally open operation. The outputs shall be configurable to respond to Mutes, Preset Recalls, Audio Playback and Level Sensing. An optional 8x8 networkable GPIO interface shall be available for expansion of the GPIO functionality.Networkable, PoE-enabled remote controllers shall be available to complement the unit, including wallplate controllers in both US and EU formats, and desktop controllers with a minimum of 8 motorized faders and 8 LCD displays.The unit shall have an integrated power supply accepting AC mains voltages of 100-240V, 50/60Hz, 70W max via an earthed 3-pin IEC C6 male connector mounted on the rear chassis. A DC input for backup power supply shall be included, capable of accepting a 12V input on a 2-pin Phoenix terminal block. For redundant power supply operation, the internal power supply shall be capable of operating simultaneously with an external DC supply.The unit shall be the Allen & Heath AHM-64.
