The Sonifex AVN-PXH12 is a compact 1U monitor-mixer designed for Audio over IP (AoIP) applications. It enables AES67-compatible streams on your network to be assigned to channels and mixed down to analogue outputs, headphones, and an integrated speaker. The unit supports monitoring of up to 12 sources simultaneously, selected from a total pool of 24 inputs. These sources can be drawn from four stereo analogue inputs; one front-panel 3.5mm jack, two rear-panel 3.5mm jacks, and one rear-panel stereo XLR pair, or from RAVENNA, AES67, and AES67-enabled Dante® streams.
Product Features
Using AES67 standard, ensuring interoperability with most AoIP systems. The unit uses RAVENNA to deliver full AES67 compatibility.
A built-in web server provides complete configuration. All channel sources can be assigned and adjusted from a single, intuitive interface.
SAP discovery enables identification of compatible devices and monitoring of Dante® AES67 streams.
Translucent, illuminated channel controls provide clear, at-a-glance level monitoring.
Dedicated Mute buttons and a Solo function allow rapid auditioning of individual or multiple channels.
‘Normal’ and ‘Alternate’ inputs per channel can be switched in under 1 ms for accurate A/B comparison.
Each channel can be routed to the left ear, right ear, or stereo mix for flexible headphone monitoring.
Front-panel headphone outputs (6.35mm and 3.5mm) and an integrated speaker, each with independent level control.
Supports sources from AoIP streams, balanced analogue, and three unbalanced inputs.
Flexible routing to AoIP streams or rear-panel balanced outputs.
Dual 1Gb Ethernet ports and a 1Gb SFP fibre interface for network connectivity.
Ten user-configurable GPIO ports for external control and integration.
Redundant power via dual AC and DC inputs.
Full control and configuration via Ethernet-connected web interface.
Dedicated speaker mute control.
Typical Applications
Production gallery or control room channel monitoring positions, OB truck monitoring, confidence channel monitoring of any AoIP installation.
