When
a power amplifier fails, DC appears at the output, rendering
in most cases, the loudspeaker useless.
The
DCpro is sonically transparent. Power from the amplifier is
only routed through a quality 16A Finder power relay before
reaching the loudspeaker. When DC in excess of +/- 0.6V is
sensed, the DCpro's fast acting detector triggers a relay,
instantaneously breaking the connection between the amplifier
and the speakers.
A
much welcomed feature of the DCpro is a Soft Start of about
1/2 sec delay on power up. This effectively eliminates any
switch on thumps that plague some amplifiers.
