Key Features

Dual Channel Flexibility: Operates as two independent 1x4 DAs or a single 1x8 DA for flexible signal distribution.
Advanced Jitter Reduction: Reclocking regenerates digital audio waveforms and reduces timing jitter at 32, 44.1, 48, and 96kHz sample rates.
Extended Cable Equalization: Compensates for cable losses up to 300m over Belden 1800B balanced twisted-pair cable at 48kHz.
Transformer-Coupled Inputs: Provides 110Ω balanced input isolation to prevent ground loops and electrical interference.
High-Density Rack Design: Occupies one slot in the 3RU Evertz 400FR frame, supporting up to 16 modules per chassis.
Real-Time LED Diagnostics: Indicates module health, reclock lock status, PLL out-of-lock, parity errors, and biphase coding faults.

Product Overview +

Versatile Dual-Channel AES Signal Distribution

The Evertz 400DA2Q-AESB is a dual-channel reclocking distribution amplifier engineered for $110\ \Omega$ balanced AES3 digital audio signals. Designed for broadcast master control, recording studios, and live production racks, the card splits incoming digital audio signals into multiple isolated outputs without signal degradation or phase jitter.

Flexible Operating Modes & Extended Cable Reach

Configurable Architecture: Operating as either a dual 1x4 DA or a single 1x8 DA, the module adapts easily to varying facility requirements.
Long-Distance Equalization: Automatically compensates for high-frequency signal loss across cable runs up to 300 meters using Belden 1800B or equivalent $110\ \Omega$ cable.
Data Reclocking: Re-clocks incoming bitstreams up to 96 kHz, restoring clean digital edges for downstream equipment.

High-Density Modular Integration

The 400DA2Q-AESB occupies a single slot in the 3RU Evertz 400FR frame, accommodating up to 16 cards per frame for up to 128 balanced AES outputs in 3RU. Card-edge LEDs provide immediate visual status for rapid troubleshooting.
