Instructions for use
Thank you for purchasing the Musical Fidelity M1 HPA.
The M1 HPA consists of a pure class A circuit giving exceptional performance into virtually any impedance
headphones.
It features a line as well as a USB input, and a line (loop) output. It also features two headphone
sockets and a set
of volume-controlled outputs to enable use as a preamplifier. It is complemented with a generous
power supply circuit, allowing astounding imaging, detail and transparency,
to deliver all music types exactly as the
artist originally intended.
The M1 HPA 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.
