Radio Design Labs FP-SPR1
SPDIF Repeater / Amplifier


Radio Design Labs' FP-SPR1 is the ideal product for applications requiring either conversion between SPDIF connector types or recovery of low level SPDIF signals. Power connections are made using either the full-size barrier block terminals or a dc power jack located in one end panel. A second dc power jack is provided on the other end panel for connecting additional FLAT-PAK modules.

The FP-SPR1 is a single channel module featuring three separate inputs. An input is provided in each conventional SPDIF format: BNC, phono and optical. Any one of these inputs may be used. A coaxial input has priority over the optical input. Three output jacks are also provided: BNC, phono and optical. Either of the coaxial jacks may be used and/or the optical output may be connected. It is possible to use only one of the three outputs or use one coaxial and the optical output simultaneously. A front-panel LED illuminates when an input signal of sufficient amplitude is received to produce the correct output from the module.

NOTE: Radio Design Labs' PS-24AS power supply is NOT included but is required in order to power this product.  Please see the "Accessories" tab or click here for more information on the PS-24AS power supply.
