AMA-8511 User Manual (Iss. 03) Introduction • 1-1
Overview
The RossGear AMA-8511 AES/EBU Distribution Amplifier and Converter is a broadcast quality
digital AES/EBU audio reclocking distribution amplifier, as well as a modular product used to convert
20 or 24 bit AES-3id (coaxial) signals to analog audio. The AMA-8511 accepts one 32, 44.1, or
48kHz sample rate AES/EBU audio signal and provides two copies of balanced stereo (A, B) analog
audio and four reclocked copies of the input signal. The RossGear AMA-8511 is designed for use in
75-ohm coaxial SMPTE 276M or AES-3id systems.
The AMA-8511 provides automatic cable equalization for lengths up to and beyond 610m (2000 ft.).
The D/A converter uses a state of the art 24bit 128X over-sampled Delta Sigma Modulator DAC to
convert to analog audio. Following the D/A conversion, the analog audio passes through a very high
quality reconstruction filter that assures low distortion and noise. Two identical copies of the analog
signal are output via the rear plug-on module, the CON-8516 AES Audio Connector (included with
the card).
A coarse level adjustment headroom jumper (18dB or 24dB), and a fine adjustment potentiometer
(±6dB) are provided to precisely match to your facility’s house reference audio level. The AMA-8511
can accommodate any full-scale digital (FSD) level in the -12 to - 30dBFS range. Automatic detection
of AES/EBU 50/15µs de-emphasis is available for all data rates.
The AMA-8511 has been designed with the capability to report a variety of AES signal errors
including No Lock, Coding, Parity, CRC, and Validity. These errors are indicated on a card edge
LED. In addition, there is a SMPTE 269M fault reporting output to the back of the Ross frame.
The AMA-8511 fits into Ross 8000A series digital frames, the DFR-8110A (2RU) and the DFR8104A (1RU), and provides system builders with the ability to easily distribute and convert digital
audio within a facility.
A reclocking amplifier is the preferred method of distribution for long coaxial runs to reduce jitter in
the data stream. The AMA-8511 performs reclocking in a two-stage process that develops an output,
which is stable and noise-free.
The AMA-8511 is part of a complete line of RossGear AES solutions that includes distribution,
conversion, and monitoring. Designed and manufactured to meet the highest quality broadcast
industry standards, the RossGear AMA-8511 is an ideal, flexible, and cost effective solution for your
digital audio reclocking distribution and digital to analog conversion requirements.
