RDL has debuted a line of 192 kHz digital audio products with support for AES/EBU, S/PDIF and AES-3ID formats, the Half-Rack series.
As the name suggests, the units are half-rack width; two HR units can be mounted in a vertical rack space using an RDL HR-RA2 rack adapter.
The HR-DAC1 digital-to-analog converter detects a valid input on any of four input jacks. A front-panel Lock LED indicates the presence of a valid digital audio source without any phase lock or bit errors. Digital input is converted to stereo analog using delta-sigma conversion, digital filtering and filtered wideband analog drivers.
The HR-DDA4 digital audio distributor decodes input, reclocks it and transmits to four individually buffered outputs. Front-panel LEDs display the digital audio format and sample rate of a valid source received.
The HR-DSX4 digital audio switcher uses solid-state switching to select one of four inputs. Front-panel features include four keyboard-style source selection pushbuttons with corresponding LEDs. Upon selecting a source the associated input LED lights if a valid digital audio signal is present and flashes if not present.
The HR-UDC1 universal digital audio converter is suitable for installations where digital signals must be converted between consumer and professional formats.
