Sonifex AVN-PXH12 12x2 Channel Mixer Monitor, AES67 Portal Rackmount

Sonifex AVN-PXH12 12x2 Channel Mixer Monitor, AES67 Portal Rackmount

Compact 1U format rack monitor mixer Sonifex AVN-PXH12 is primarily intended for Audio Over IP audio channel monitoring. You can designate any AES67 audio channel on your network as input channels on the device, and then mix those channels down to analog outputs, a headphone output, and an integrated speaker.

This stereo monitoring gadget lets you see up to 12 audio sources at once from a total of 24 inputs. The four discrete stereo analog audio inputs (one each for the front panel, rear panel, and stereo XLR input pairs) and any RAVENNA, AES67, or AES67-enabled Dante® AoIP linked streams can be used to choose from among the 24 audio sources.

The 12 x control channels on the front panel, each with a "Normal" and "Alternate" input selection, receive these stereo signals. There are three buttons on each channel: one for selecting the input, one for muting the channel, and a third for choosing whether the channel's input should go to the left, right, or stereo output legs.

Each channel has a knob that not only indicates the input level in red, amber, or green but also regulates the level of input that is sent to the output. To switch the channel input to the output, turn the "Solos" knob. The AoIP network state, synchronization status, and input status of the AC and DC power supplies are all displayed by the front panel LEDs.

Three outputs are available on the front panel: a mono-mix speaker output, paralleled stereo headphones on a 6.35mm (¼") jack, and 3.5mm jack sockets with their attenuation settings. Both the speaker and the headphones have independent volume controls, and the speaker also features a mute button. Three extra line-level XLR-3 audio outputs are located on the rear panel. These outputs can be used as physical inputs or AoIP input sources, or they can be designated as mono mix or left or right channel outputs of the mixed audio content (corresponding to the speaker and headphone outputs, respectively).

The unit also sends to the network, as AoIP AES67 streams, the 8 channels of the 4 physical stereo inputs, together with a stereo mix of the speaker output. The unit can act as a PTP master clock or slave clock and supports IEEE1588-2008 PTPv2 media and default profiles. The rear panel contains IEC mains and secondary DC power inputs which provide power redundancy to the product. There are two Ethernet RJ45 connections (control and AoIP) and there is an Ethernet SFP module that, when used, replaces the AoIP RJ45 connection. A rear panel GPIO connector provides 10 local ports which can be user configured as inputs or outputs and provide software-controlled functionality. A voltage free relay contact can be used to operate external equipment. A built-in web server provides complete configuration control of the unit including source assignment to each channel and also allows for firmware updates and configuration backup. The unit can be controlled by suitable Ember+ commands.

Key Features

• AES67 as a format has been established, providing compatibility with most other AoIP products � the unit uses RAVENNA audio to ensure AES67 compatibility.
• A built-in web server is used for all configurations. Sources for all channels are simply assigned on one webpage and can be freely selected and altered at will.
• SAP can be used as a discovery mechanism to discover Dante devices and monitor Dante� AES67 streams. Dante� is a trademark of Audinate Pty Ltd.
• Confidence monitoring on the translucent volume knob for each channel so you�ve got �at-a-glance� monitoring available.
• The front panel Mute button and the Solo feature on the control knob allow a single channel, or a handful of, channels to be auditioned quickly.
• For each channel, �Normal� and �Alternate� inputs can be switched quickly (with <1msec accuracy) for direct comparison.
• Each channel can be directed to the headphone's left ear, right ear, or a stereo mix, providing you with the ability to set up a familiar headphone mix.
• 6.35mm (1/4�) & 3.5mm headphone outputs and a speaker output with separate LS & HP volume controls.
• Sources from AoIP, balanced or 3 x unbalanced inputs.
• Destinations to AoIP or rear panel balanced outputs.
• Dual 1Gb lan ports & 1Gb SFP fiber port.
• 10 user assignable GPIO ports.
• Dual AC & DC power supply inputs.
• Ethernet webserver control & configuration.
• Speaker mute button.
