Overview
The RossGear ADA-8503 Dual AES/EBU Fan-Out Distribution Amplifier is designed specifically for
use in 75-ohm coaxial (SMPTE 276M or AES-3id) systems. It’s flexible configuration makes the
ADA-8503 the perfect choice for low cost AES distribution within your facility. By moving an on-
board jumper, the ADA-8503 can be set as a single, fan-out distribution amplifier; or as a dual, fan-out
amplifier. The single configuration provides one input and eight outputs, while the dual configuration
provides the first amplifier with one input and four outputs, and a second amplifier with one input and
three outputs.
The ADA-8503 distributes incoming data at 22 to 100kHz sampling rates and provides automatic
cable equalization for lengths beyond 610m (2000 ft.). It also has been designed with an AES input
signal presence detector and indicator LED's.
The ADA-8503 fits into the Ross 8000A series digital frames, with ten cards in the DFR-8110A
(2RU) and four cards in the DFR-8104A (1RU). Designed and manufactured to meet the highest
quality broadcast industry standards, the ADA-8503 Utility DA is an ideal, flexible, and cost effective
solution for the distribution of AES/EBU signals where reclocking is not required. The ADA-8503
also fits Leitch
*
6800 series frames.
The ADA-8503 Dual AES/EBU Fan-Out Distribution Amplifier is part of a growing line of RossGear
AES solutions, including distribution, conversion, and monitoring.
