Instructions for use
Thank you for purchasing the Musical Fidelity M1 PWR.
The M1 PWR consists of a top quality Class-D switch-mode power amplifier circuit giving exceptional performance
into virtually any speakers. It features efficient switching technology with zero crossover distortion artefacts and with
just the right amount of feedback to give the best sound quality possible. It may also be used in a monoblock mode
(with a matching amplifier for the other channel) in which the power output is considerably increased. It is
complemented with a generous universal voltage power supply circuit, allowing astounding imaging, detail and
transparency, to deliver all music types exactly as the artist originally intended. A line (loop) output allows for further
or future expansion.
The M1 PWR has been carefully designed to be partnered with M1 series, and also matches well with M3 and M6
series products. These combinations will yield one of the best high-fidelity systems available at any price.
Used 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 any questions about the audio system, please consult the dealer who is there to help and advise.
