Product Overview +

High-Density Analog Audio Demuxing

The Evertz 7707AR-A series (7707AR-A8 and 7707AR-A12) are professional optical-to-analog audio demultiplexers designed to recover 8 or 12 balanced analog audio channels over a single fiber optic cable. Perfect for broadcast facilities, live production trucks, and venue interconnects, these cards convert incoming multiplexed optical streams back to high-grade analog audio with zero signal degradation.

Broadcast-Grade Fidelity & Control

Equipped with multi-pin removable terminal blocks, each module supports maximum output levels of +24 dBu (high impedance) or +23 dBu (600Ω load). Operators can adjust individual channel gain from -10 dB to +10 dB in precise 0.5 dB increments directly from the card-edge UI or remotely over SNMP/VistaLINK. Local signal checks are made effortless thanks to a card-edge 1/4" headphone monitoring output and visual status display.
