RDL HRUDC1 Quick Start Guide

HALF-RACK SERIES

Model HR-UDC1
Universal Digital Audio Converter

• Data Conversion Between S/PDIF and AES/EBU

• Electrical Conversion Between Digital Audio Formats

• Input: AES/EBU, Coaxial or Optical S/PDIF

• Output: AES/EBU, Coaxial or Optical S/PDIF, AES-3ID

• Operation Up to 24 bits, 192 kHz

The HR-UDC1 is an RDL HALF-RACK product, featuring an all metal chassis and the advanced circuitry for which RDL products are known. HALF-RACKs may be
operated free-standing using the included feet or may be conveniently rack mounted using available rack-mount adapters.

APPLICATION: The HR-UDC1 is the ideal choice in installations where digital audio signals must be converted between
consumer and professional formats. The input and output support AES/EBU, S/PDIF and AES-3ID formats. The HR-UDC1
automatically detects a valid input on any of the four input jacks: S/PDIF optical, S/PDIF coaxial, AES-3ID or AES/EBU. The input
is decoded, reclocked and transmitted to the output. All pro/consumer, emphasis, and sampling frequency bits common to both
S/PDIF and AES/EBU standards are inserted in the output data stream. Front-panel LEDs display the digital audio format and
sample rate of a valid source received without any phase-lock or bit errors.

The output is switch-selectable to provide an AES/EBU, S/PDIF coaxial or optical, or AES-3ID output. The switch enables the
appropriate output jack and any required electrical and data format conversion. The AES/EBU input and output are 110 Ω
terminated; the S/PDIF coaxial and AES-3ID jacks are 75 Ω terminated.

The HR-UDC1 is powered from 24 Vdc, which may be connected through the detachable terminal block or through the dc power
jack. A front-panel power switch is provided.

RDL’s proprietary
bringing a high level of stability to digital audio signal conversion under the variety of conditions encountered in professional
environments.

Use the HR-UDC1 individually, or combine it with other RDL products as part of a complete audio/video system.
