The HR-DDA4 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-DDA4 is the ideal choice in installations requiring high quality distribution of a digital audio signal. The
input and each of the four outputs support AES/EBU, S/PDIF or AES-3ID formats. The HR-DDA4 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 four individually buffered outputs. Front-panel LEDs display the digital audio format and sample rate of a valid
source received without any phase-lock or bit errors.
Each output is switch-selectable to provide an AES/EBU, S/PDIF coaxial or AES-3ID output. The switch enables the appropriate
output jack and any required electrical and data format conversion. The AES/EBU input and outputs are 110  terminated; the
S/PDIF coaxial and AES-3ID jacks are 75  terminated.
The HR-DDA4 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.
