RDL FORMAT CONVERTERS - HR Series - Digital audio
The HR-UDC1 Universal Digital Audio Converter converts a digital audio signal between consumer and professional formats. Operating at up to 24-bit resolution and 192kHz sampling rate, It automatically detects a valid input on any of the four input sockets, S/PDIF optical, S/PDIF coaxial, AES-3ID or AES/EBU. The input is decoded, re-clocked and re-transmitted to the output. The output has a switch to select an AES/EBU, S/PDIF coaxial or AES-3ID output. LEDs display the digital audio format and sample-rate of a valid source received without any phase-lock or bit errors. 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'.
RDL's HR series are 'Half-Rack' Series products with an 'all-metal chassis' which may be used free-standing, using the feet supplied. Each unit may be labelled by removing an end cap and sliding out a clear plastic cover, which can be slid back in to cover users labels, much in the manner of standard designation strips. Two units may be mounted side-by-side in an optional 1U 19-inch rack adapter.
The front panel has two LEDs to indicate the detected input format, S/PDIF or AES/EBU, and nine LEDs to show the detected sampling-rate from 32kHz to 192kHz. The power button has an associated LED to indicate power is present.
The rear has two groups of connectors, for input and output. Each group has RCA(phono), BNC and XLR connectors for S/PDIF, AES3iD and AES/EBU respectively, and an optical connector for S/P/DIF. The input connector in use is determined automatically, as is the sample-rate of the incoming feed. The output has a switch which selects the connector to be used. Both a co-axial connector and a detachable terminal block are provided for connecting power.
