SPDIF Repeater Amplifier



  • Correct SPDIF Signal Level from Long Line
  • Conversion Between SPDIF Connector Types
  • BNC, Phono and Optical Inputs
  • BNC, Phono and Optical Outputs
  • Reshape SPDIF Waveforms
  • Virtually Jitter-Free Performance
  • Convenience of RDL® FLAT-PAKs™

APPLICATION: The RDL-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 RDL-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.
