SUPERCHARGER 

750K 

MONOBLOCK BRIDGED POWER AMPLIFIER 

INSTRUCTIONS  FOR  USE

 

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 package. Used properly and 
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. 
 If there are further questions about any Musical 
Fidelity component, please consult the dealer 
from whom it was purchased, who is there to 
help and give advice.
