Key Features

1x4 Balanced AES Distribution: Distributes one transformer-coupled 110Ω AES3 input to four reclocked 110Ω balanced outputs.
Adaptive Equalization & Reclocking: Compensates for up to 300m (984ft) of Belden 1800B cable at 48kHz while reducing signal jitter.
Multi-Rate Sampling Support: Supports 32kHz, 44.1kHz, 48kHz, and 96kHz digital audio sampling rates.
Transformer-Coupled Isolation: Provides input isolation to prevent ground loops and maintain signal integrity.
Removable Terminal Connections: Uses 3-pin removable terminal strips with included screw-down adapter modules.
Comprehensive Monitoring & SNMP: Card-edge LEDs indicate module health, reclocker lock, PLL status, parity errors, and biphase coding errors, with remote SNMP monitoring via the 500FC Frame Controller.

Product Overview +

Professional Balanced AES Digital Audio Distribution

The Evertz 500DA-AESB is a broadcast-grade 1x4 reclocking and auto-equalizing distribution amplifier designed specifically for balanced $110\ \Omega$ AES3 digital audio signals. Built for master control rooms, recording suites, and live broadcast infrastructure, it accepts a single balanced AES3 digital stream and delivers 4 pristine, jitter-reduced outputs across long cable runs.

Long-Distance Cable Equalization & Jitter Reduction

Automatic Long-Run Equalization: Integrated adaptive equalization compensates for cable attenuation up to $300\text{ m}$ over standard Belden 1800B twisted-pair cabling.
Active Data Reclocking: Restores digital pulse shapes and eliminates accumulated timing jitter before routing to downstream audio processors, routers, or consoles.
High-Resolution Sampling: Supports digital audio streams with sampling rates up to $96\text{ kHz}$, making it ideal for standard broadcast and high-sample-rate production workflows.

High-Density Modular Chassis Architecture

Designed to fit the 3RU Evertz 500FR frame, up to 16 500DA-AESB cards can be installed per chassis to support up to 64 balanced AES outputs. Quick-check card-edge LEDs provide instant status updates for fast diagnostic checks, while SNMP support allows centralized management across large facility networks.
