Product Overview +

High-Performance Analog Audio Splitting & Distribution

The Evertz 7700ADA-AUD is a general-purpose, dual-channel analog audio distribution amplifier designed for professional broadcast facilities, recording suites, and master control environments. Built for high-density signal distribution, it delivers clean, uncolored analog audio signals across multiple destinations without loading effects or crosstalk.

Flexible Stereo/Mono Configuration & Fine Gain Staging

Dual Operational Modes: Operate as two independent 1x4 amplifiers for stereo left/right pairs, or combine channels into a single 1x8 amplifier when high-fanout mono distribution is required.
Multi-Stage Level Tuning: Jumper coarse gain stages combined with card-edge trim potentiometers allow precise gain matching across various pro-audio line levels.
Ultra-Low Noise Architecture: Extended dynamic range ($119\text{ dB}$ SNR) and exceptional headroom (up to $+34\text{ dBu}$ max input level) preserve signal integrity in critical production signal chains.

Modular Frame Integration

Designed to occupy a single slot in the Evertz 7700FR, 7800FR, and 570 series 3RU frame chassis, multiple cards can be installed per frame to build high-density distribution systems. Card-edge LEDs provide instant visual indication of module power and fault status.
