The AVN-PM8D is a powerful audio mix engine and AES67 interface with built-in mixer matrix, assignable DSP functions, GPIO, audio playback, web-enabled control and configuration, and twin TFT meter displays. It features eight mic/line inputs with switchable phantom power, eight stereo analogue line outputs, plus a dedicated AES67 Audio over IP (AoIP) portal, available via RJ45 Ethernet connection or an SFP (small form-factor pluggable) port. Recent firmware additions include tone generation, audio file playback, DTMF generation/recognition, and optional Opus codec encoding & decoding. At the heart of this unit is a powerful mix engine with web-enabled configuration and control. Any physical audio input and AES67 stream input can be mixed or routed to any physical audio output or AES67 stream output, with gain adjustment at the input, the mix point or the output. DSP functions, such as gain and filtering, can be added at inputs, outputs and cross-points.
Product Features
Eight balanced XLR mic/line inputs and eight stereo line outputs on RJ45 connectors using StudioHub® pinout.
AES67 portal on 1Gb Ethernet (RJ45) and 1Gb SFP ports.
Gain and DSP functions available at inputs, outputs, and crosspoints.
Twin TFT Meter displays with selectable ballistics, plus phase and channel ident display.
Up to eight AoIP input streams with a maximum of 16 channels to be routed.
Up to eight AoIP output streams with a maximum of eight channels each (64 channels).
Audio file playback.
DTMF tone generation/recognition
Optional multi-channel Opus codec encoding and decoding
Dual AC and DC power supply inputs.
10 user assignable GPIO ports.
Typical Applications
An eight output zone microphone mixer, an eight-channel clean-feed generator with input mixing and gain control on inputs and outputs, distribution of eight stereo channels of audio over an SFP fibre connection, an IFB generator to send 64 x AES67 streams to individual belt-packs, an eight output headphone distribution system with separate input mixes for each headphone output and individual gain control; an input mixer with input/output metering and AES67 stream generation, an 8 stereo channel Opus encoder, or decoder.
