The Aviom 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 is input on standard Cat-5e cable, via Aviom's A-Net Pro16 digital audio transmission protocol and converted to analog using 24-bit, 48kHz converters. Sixteen balanced outputs are provided on the rear panel via multipin connectors. Designed to be compatible with a wide range of signal level requirements, each pair of channels has a four-position output level switch with settings for +24, +18 and +4dBu line-level, or mic-level output. Each channel features front-panel LEDs for signal present and clip. The AN-16/o v.4 features rugged DB25 multipin connectors for analog audio outputs, reducing set-up time and adding the security of a locking connection. All network connections utilize heavy duty locking Neutrik EtherCon connectors. Digital connections include A-Net In, A-Net Out and A-Net Expansion. The A-Net Out jack provides a lossless digital split of the A-Net In audio data stream, while the A-Net Expansion jack allows two 16-channel A-Net streams to be combined onto a single Cat-5e cable. With the optional AN-16SBR System Bridge, up to 64 channels can be combined onto a single Cat-5e cable in a variety of configurations (16x0, 32x0, 48x0, 64x0, 16x16, 32x16, 32x32 and 48x16). The AN-16/o v.4 can be used with any Pro16 input module or console interface card, with no limit to the number of output modules in a single system. The AN-16/o v.4 can be connected to a Pro64 audio network by adding the ASI A-Net Systems Interface.
