You Need The FP-SPR1!

The FP-SPR1 is part of the group of versatile FLAT-PAK products from Radio Design Labs. The unique
FLAT-PAK case can be directly screwed or bolted to cabinets or shelve s. Optionally available rack-mounting
accessories permit single or multiple FLAT-PAK module mounting. All FLAT-PAK modules are supplied with a
power interconnect cable for daisy-chaining multiple modules from a single power supply.

APPLICATION: The FP-SPR1 is the ideal choice in many applications where SPDIF signal levels need to be
boosted or recovered; or where a digital audio signal needs to be converted between coaxial and optical.
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.

The input sensitivity of the FP-SPR1 permits operation with coaxial input signal levels as low as 100 mV p-p.
The module detects these low signals, amplifies them and reshapes the output for minimum jitter. SPDIF
signals do not survive long cable lengths. Installation of the FP-SPR1 at the receiving end of a weak SPDIF
line restores the signal level to its correct amplitude. Although the FP-SPR1 does not reclock the signal and
cannot remove cable jitter, it can extend the useful range of SPDIF cables and avoid signal dropouts when
feeding equipment unable to correctly respond to low level signals.

A front-panel LED illuminates when an input signal of sufficient amplitude is received to produce the correct
output from the module.

The FP-SPR1’s low profile and compact size permit mounting in confined spaces and in various locations in
equipment racks. The location of the input/output jacks permits high-density mounting against flat surfaces
while maintaining accessibility to the connectors. The economical cost can provide assurance of correct signal
levels with the added feature of coaxial/optical format conversion. The FP-SPR1 may be mounted where
needed, to rack sides or in an equipment rack (either the front or rear rack rails) using the RDL FP-RRA.

Wherever professional quality is required in SPDIF format conversion or for automatic coaxial signal level
adjustment, the FP-SPR1 is the ideal choice. Use the FP-SPR1 individually, or combine it with other RDL
products as part of a complete audio/video system.
