How is DEDpro used?
The DED's front panel
has 3 diodes: green - indicating power, yellow -
indicating proper link and red - indicating data errors. Flickering of
the error diode is an early warning that there is a
problem with the media (CD, CD-R, CD-RW or DAT)
and/or with the CD or DAT player.
DEDpro also has a 6-digit LCD digital error counter and a reset button.

DEDpro and the CD-CHECK compact disc
DED can be used with a CD-CHECK disc
and other
tracking-testing discs (a CD player with optical or
coaxial output is required). Play the CD-CHECK disc
and observe the red error diode to flash whenever
there is an error. Flash of the diode is accompanied
by the distinctive click or muting of the audio signal
which can be heard in speakers or headphones.
The 6-digit LCD digital error counter counts all errors
generated during playback.
This allows for the objective measure of the "error
correction headroom" (i.e. player's ability to correct data
errors) and tracking (i.e. player's ability to stay
on track despite of disc surface or other errors).
The CD-CHECK disc contains
special digital signals and error patterns to quickly,
safely and routinely perform tests.
Who benefits the most from using DEDpro?
DED should be of importance to recording studios, radio stations,
sound archives, duplication centers, service centers,
audiology clinics, sound research centers, theaters,
concert halls, ice skating events and to audiophiles
and all those who are concerned about quality and
faithful reproduction of music and sound. Intercepting
errors will allow you to avoid embarrassing skipping
and muting of sound during public performances and other events.
