Introduction
Overview
The RossGear ADA-9503 AES/EBU Equalizing Amplifier is a high quality
distribution amplifier for digital audio signals and part of a growing family of
GearLite self-contained, small brick-format modules.
The ADA-9503 is a one-input, six-output program stream digital audio fan-out
distribution amplifier and is specifically designed for use in 75ohm coaxial
(SMPTE 276M or AES-3id) systems.
The ADA-9503 distributes incoming data at 22 to 100kHz sampling rates and
provides automatic cable equalization for lengths beyond 610m (2000ft).
The ADA-9503 provides an ideal and cost effective solution for the distribution
of AES/EBU signals where re-clocking is not required.
The ADA-9503 includes a universal power adaptor and line cord suitable for the
country of use. Various mounting options are included that enable a wide range
of installation choices for this compact, stand-alone package.
