Radio Design Labs HR-UDC1

The RDL 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, re_clocked and retransmitted 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 Ohms terminated; the S/PDIF coaxial and AES-3ID jacks are 75 Ohms 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 Sure-Lok auto recovery supervision monitors possible causes of latch-up and reinitiates digital signal lock, bringing a high level of stability to digital audio signal distribution under the variety of conditions encountered in professional environments. PS24AS power supply not included.
