Key Features

1x9 Unbalanced AES Distribution: Distributes one transformer-coupled 75Ω AES3 input to nine reclocked 75Ω BNC coaxial outputs.
Extreme Cable Equalization: Compensates for cable losses up to 1500m (4920ft) over Belden 1694A at 48kHz.
Jitter-Reducing Reclocking: Restores digital waveform integrity and reduces timing jitter at 32kHz, 44.1kHz, 48kHz, and 96kHz.
SMPTE ST 276 Compliance: Supports AES3 digital audio transmission over standard 75Ω coaxial infrastructure.
Transformer-Coupled Isolation: Prevents ground loops and provides electrical isolation on single-ended coaxial connections.
Real-Time Diagnostics & SNMP: Card-edge LEDs monitor module health, reclocker lock, PLL status, parity, and biphase errors, with SNMP support via the 500FC Frame Controller.

Product Overview +

High-Density Unbalanced AES Digital Audio Distribution

The Evertz 500DA-AESU is a broadcast-grade 1x9 reclocking and auto-equalizing distribution amplifier engineered for $75\ \Omega$ unbalanced AES3 digital audio signals (SMPTE ST 276). Designed for master control, production trucks, and large broadcast facilities, it splits a single coaxial AES stream into 9 clean, jitter-free outputs without signal degradation.

Long-Distance Cable Compensation & Clock Restoration

Extended Coaxial Reach: The onboard equalization engine automatically recovers degraded $75\ \Omega$ AES digital signals across coaxial runs up to $1500\text{ m}$ using Belden 1694A cable.
Jitter Reduction: Restores pulse integrity and eliminates phase jitter prior to distribution, ensuring maximum stability for downstream audio routers, consoles, and embedders.
Broad Sample Rate Support: Native compatibility with standard digital sampling rates from $32\text{ kHz}$ to high-resolution $96\text{ kHz}$.

Modular Integration & System Monitoring

Occupying a single slot in the 3RU Evertz 500FR frame, up to 16 cards can be populated per chassis for up to 144 distributed coaxial AES outputs. Card-edge LEDs provide instant status updates, while centralized management is enabled via SNMP when paired with the 500FC Frame Controller.
