Key Features

1x9 Balanced AES Distribution: Distributes one 110Ω balanced AES3 input to nine identical reclocked 110Ω outputs via 3-pin removable terminal strips.
Advanced Data Reclocking: Removes accumulated timing jitter and supports 32kHz, 44.1kHz, 48kHz, and 96kHz sampling rates.
Extended Cable Equalization: Compensates for up to 300m of Belden 1800B twisted-pair cable at 48kHz.
Transformer-Coupled Input: Provides isolation against ground loops and common-mode noise on 110Ω lines.
High-Density Modular Design: Occupies one slot in the Evertz 3RU 400FR frame, supporting up to 16 modules per chassis.
Comprehensive Status Diagnostics: Card-edge LEDs indicate module health, reclock lock status, PLL out-of-lock, parity errors, and biphase coding faults.

Product Overview +

Robust Digital Audio Routing & Conditioning

The Evertz 400DA-AESB is a high-performance 1x9 reclocking distribution amplifier engineered for balanced $110\ \Omega$ AES3 digital audio signals. Built for broadcast control rooms, production trucks, and studio facilities, the module splits and regenerates digital audio streams across nine isolated outputs without introducing jitter or signal degradation.

Signal Integrity over Long Cable Runs

Automated Equalization: Compensates for high-frequency attenuation caused by long twisted-pair cable runs, reliable up to 300 meters using Belden 1800B or equivalent cabling.
Jitter Reduction: Reclocks the incoming serial bitstream at standard rates up to 96 kHz, restoring clean pulse edges before outputting to downstream gear.
Isolation: Transformer coupling ensures proper impedance matching ($110\ \Omega$) and suppresses ground-induced electrical interference.

Fault Monitoring and Rack Density

The module integrates seamlessly into the Evertz 3RU 400FR frame, allowing up to 16 DA cards per frame (144 total balanced AES outputs in 3RU). Quick-view card-edge LEDs alert engineers immediately to PLL lock failures, parity violations, or biphase coding faults for efficient troubleshooting.
