The HR-DSX4 is the ideal choice in installations requiring high quality source selection between digital audio signals. Solid-state switching is used to select one of four inputs. Each input may be fed through one of three jacks: S/PDIF optical, S/PDIF (or AES-3ID) coaxial or AES/EBU. The output is switch-selectable to provide an AES/EBU, S/PDIF coaxial, S/PDIF optical or AES-3ID output. The switch enables the appropriate output jack and any required electrical and data format conversion. The AES/EBU inputs and output are 110 Ω terminated; the S/PDIF coaxial and AES-3ID signals connect through 75 Ω terminated phono jacks. RDL's proprietary Sure-Lok™ auto recovery supervision monitors possible causes of latch-up and reinitiates signal lock to provide highly stable operation in the variety of conditions encountered in professional environments.

The front panel features four high-reliability, keyboard-style source selection pushbuttons with corresponding LEDs. Upon selecting a source, the LED lights if a valid input is present; otherwise it flashes. If the button for a selected source is pushed again, all inputs are turned off. A front-panel LOCAL/REMOTE switch enables either the front-panel buttons or the rear-panel remote control terminals provided on detachable terminal blocks. In the REMOTE mode, inputs are selected by an external switch or open-collector closure to ground, which may be momentary or continuous. When a source is selected, the HR-DSX4 provides a 50 mA open-collector output to control other equipment or modules.

The HR-DSX4 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.

HALF RACK

RDL Half-Rack products are studio quality electronic equipment in durable metal enclosures ½ rack width, 1RU in height. This series includes both digital and analog products with front-panel user controls and indicators. Connectors are located on the rear panel. Chassis are finished in black powder coat. The front panels feature a full color reverse-printed polycarbonate laminate surrounded by raised end caps and the product label track. The distinctive appearance of the Half-Rack products complements rack mounting or standalone use.

Available RDL accessories permit one or two Half-Rack products to be mounted in 1 RU. Rack mounting is easy and takes only seconds. The product drops into the rack adapter, slides forward and is secured by tightening four screws. For standalone use, each product is supplied with rubber feet secured by screws.

Attractive styling, superior performance, high quality panel controls and connectors, and durable construction make RDL Half-Rack products a preferred long-term resource for system design solutions. HALF RACK SERIES modules are designed and manufactured in the U.S.A.
