MONOBLOCK BRIDGED POWER AMPLIFIER
INSTRUCTIONS FOR USE
750K
Thank you for purchasing the Musical Fidelity
Supercharger 750K monoblock.
The Supercharger 750K uses the latest in low
distortion circuitry in a bridged configuration
which delivers 750 watts rms.
The Supercharger 750K is designed to increase
the dynamic range of an existing lower powered
amplifier (from 50 watts to 200 watts) to a
maximum of 750 watts. The dynamic range will
increase by up to 10dB. This does not
necessarily mean that the average listening level
will be much louder; it's just that musical
transients will now be delivered without
distortion or limiting. Overall the listening
experience is greatly improved because of
dramatically lower distortion and increased
dynamic range.
The 750K accepts both speaker level and line
level inputs. When driven from an existing
amplifier the sound quality is greatly improved
because the 750K presents an easy load for the
existing amplifier to drive and at the same time
gives up to 10dB increase in dynamic range.
Alternatively, the Supercharger 750K can be
used as a conventional power amplifier driven
by a high quality preamp.
The Supercharger 750K is a perfect answer to
improve dynamic range in a single beautifully
engineered
carefully, it should give many years of
outstanding musical reproduction.
Dust regularly with a soft duster or soft brush,
but be careful when using cleaning or polishing
agents - they may harm the surface finish.
