The AVN-PA8 is a powerful audio mix engine and AES67 interface with built-in mixer matrix, assignable DSP functions, GPIO, audio playback, and web-enabled control and configuration. It features eight stereo analogue line inputs, 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 stereo analogue inputs and eight stereo analague outputs on D-type sockets with AES59 pinout, paralleled with eight 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.
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 analogue zone 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.
