High-Performance Broadcast Audio Distribution

The Evertz 500ADA-AUD is a general-purpose 1x4 analog audio distribution amplifier built for high-density signal splitting in broadcast control rooms, production trucks, and recording environments. It accepts one analog audio input and distributes four isolated, low-impedance outputs without signal degradation or ground-loop crosstalk.

Flexible Input Handling & Multi-Stage Gain Precision

• Universal Input Compatibility: High-impedance differential inputs automatically adapt to single-ended or balanced signals, maintaining excellent noise rejection even in electrically noisy environments.
• Multi-Stage Level Adjustment: Jumper-selectable coarse gain steps combined with a card-edge potentiometer allow precise gain staging across various pro-audio operating levels.
• Ultra-Clean Signal Path: Ultra-low distortion ($\text{THD+N } 0.001\%$) and extended headroom (up to $+34\text{ dBu}$ max input level) preserve signal integrity for high-fidelity audio workflows.

High-Density Modular Deployment

Housed in a single slot of the 3RU Evertz 500FR frame, up to 16 modules can be installed per chassis to provide up to 64 analog audio outputs. Card-edge LED indicators provide instant verification of module health and power supply status.
