The FP-SPR1 is the ideal product for applications requiring either conversion between SPDIF connector types or recovery of low SPDIF signal levels. 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 SIGNAL LED illuminates when an input signal of sufficient amplitude is received to produce the correct output from the module.
