AN-16/o v.4 Output Module
AN-16/o v.4 Output Module


  • 16 balanced mic- or line-level outputs
  • Four-position output level switch per channel pair
  • +24, +18, and +4dBu line-level, or mic-level outputs
  • 48kHz, 24-bit D/A converters
  • DB25 output connectors

The AN-16/o v.4 Output Module connects to any Pro16 input module, console card, or A-Net distributor and provides 16 balanced line-level analog outputs using two DB25 multi-pin connectors. Four output levels, from mic to +24dBu, are available to easily accommodate the input level requirements of the device the AN-16/o v.4 output signals are being connected to.

Use the AN-16/o v.4 anywhere analog outputs are required: with the A640 and A360 and D800's Network Mix Back feature for wireless in-ears, on stage or at FOH in a digital snake, in the studio, or for a recording split. Adding a digital split to a Pro16 system is as simple as connecting an additional AN-16/o v.4 Output Module.

Compatibility Note: AN-16/o v.4 Output Modules with serial numbers 51162 and lower (from 2013 and before) are only compatible with the original version of the Pro16 A-Net protocol and not the higher channel count Pro16e version of A-Net. The Pro16e version of A-Net is used by the AN-16/i v.2 as well as the D800 and D400 series of A-Net Distributors.

Product Details

The AN-16/o v.4 Output Module is a 1U rack-mount 16-channel digital-to-analog converter for Pro16® digital snake and audio distribution systems. Digital audio transmitted to the AN-16/o v.4 via Aviom's A-Net® Pro16 digital audio transmission protocol is converted to analog using 24-bit, 48kHz converters.

Sixteen balanced outputs are provided on the rear panel via DB25 multi-pin connectors. The DB25 connectors are wired to the analog standard, allowing you to purchase whatever cable length and connector format suits your application. The analog outputs can be set (per channel pair) to +24dBu, +18dBu, +4dBu, or mic level.

Connecting to Wireless In-Ear Monitors

In personal mixing systems using the A640 and/or A360 Personal Mixers with the D800 or D800-Dante A-Net Distributors, the AN-16/o v.4 simplifies connections to wireless IEM systems.

Each A640 or A360 Personal Mixer sends its stereo mix output back into the network which appears as a pair of channels on the AN-16/o v.4. Each AN-16/o v.4 supports up to eight A640 or A360 mixers. Simply patch the analog outputs on the AN-16/o v.4 into the IEM transmitter's inputs. No analog cables are required at the A640 or A360 on stage. Learn more about Network Mix Back.

Digital Snakes and Audio Networks

Use the AN-16/o v.4 anywhere analog outputs are required: on stage or FOH in a digital snake, in the studio, for a recording split, or in even the most complex audio networks. Adding a digital split to a Pro16 system is as simple as connecting an additional AN-16/o v.4 Output Module.
