The AV-M8 Mic Input Module provides eight mic-level inputs to a Pro16 system. Two channels also include a 20dB switchable pad for line-level inputs. Eight channels of digital audio may also be input via ADAT®, from a second AV-M8 module. The unit may be mounted in a rack or to a table or podium, using the reversible mounting flanges or detachable rack ears.

Analog audio is input via eight latching 5.0mm Euroblock connectors. Each analog input channel features configuration DIP switches for individually selectable gain settings, +48V phantom power, and low cut filter.

Analog input channels are routed to Channels 1-8 in the A-Net® stream, while channels input via ADAT become A-Net Channels 9-16. Stereo linking for all eight A-Net channel pairs is supported through an eight-position rear-panel DIP switch.

A-Net connections include A-Net Out and A-Net Expansion, using locking Neutrik® EtherCon® connectors. The A-Net Expansion jack allows up to 32 channels to be carried on a single Cat-5e cable, in either 32x0 or 16x16 configurations. Larger systems (up to 64 channels on a cable) can be built using Aviom's AN-16SBR System Bridge. Pro16 A-Net supports Cat-5e cable runs up to 500ft/150m between devices. For installations requiring longer cable runs, single- or multi-mode fiber optics may be utilized, using certain standard third- party media converters.

The AV-M8 is compatible with all Pro16 Series products.
