High-Density MADI Digital Audio Signal Distribution

The Evertz 500DA-MADI is a broadcast-grade 1x8 reclocking and auto-equalizing distribution amplifier designed for AES10 MADI (Multichannel Audio Digital Interface) signals over $75\ \Omega$ coaxial infrastructure. Engineered for broadcast master control rooms, live audio production trucks, and recording facilities, it allows operators to split high-density digital audio streams (up to 64 channels per coaxial line) across multiple audio consoles, routers, and recorders without signal loss.

Advanced Signal Restoration & Extended Cable Reach

• Automatic Equalization: Adaptive input equalization automatically restores attenuation losses across cable distances up to $250\text{ m}$ over Belden 1694A coaxial cable.
• Data Reclocking: Re-clocks incoming MADI bitstreams to reduce jitter down to $0.1\text{ UI}$, ensuring reliable digital sync across downstream audio network nodes.
• Broad Payload & Sample Rate Support: Fully compliant with AES10-2003 specifications, handling standard sample rates from $32\text{ kHz}$ to $96\text{ kHz}$ across variable channel payload densities.

Chassis Integration & Network Management

Occupying a single slot in the 3RU Evertz 500FR frame, up to 16 500DA-MADI cards can be populated per frame for up to 128 reclocked MADI outputs in 3RU. Card-edge LEDs provide real-time diagnostic status, while optional VistaLINK SNMP integration via the 500FC Frame Controller allows centralized control via network software or Evertz VUE control panels.
