The M6PRX is designed to be partnered with present and future M6 series products. It features twin
conservatively rated power amplifier sections connected in dual mono configuration for the absolute best in
stereo imaging and drive capabilities. Two independent and over-specified choke regulated power supplies also

Used properly and carefully, it should give many years of outstanding musical reproduction.

GENERAL ADVICE

Installation, Precautions & User Information

This new M6PRX is designed and built to provide trouble-free performance, but as with all electronic devices it
is necessary to observe a few precautions:

• Heed all warnings shown on the back of the product.

• Only connect the M6PRX to a mains outlet having the same voltage as marked at the back of the unit.

• Always ensure that when disconnecting and reconnecting your audio equipment the mains supply is
switched off.

• Position the mains lead and signal interconnects where they are not likely to be walked on or trapped by
items placed on them.

• Do not use near water, or place water-filled containers on the M6PRX, for example, a flower vase or potted
plants. If water does spill inside, immediately pull out the mains plug from the wall socket and inform

your dealer, who should then check the unit before further use. Entry of liquid into the M6PRX is
dangerous, and may cause electric shock or fire hazard.

• Do not place the unit near direct heat sources such as radiators, direct sunlight or other equipment.

• Do not remove any covers or try to gain access to the inside. There are no internal adjustments or fuses you
can replace yourself. Refer all service work to an authorised Musical Fidelity agent.

* Note: Unauthorised opening of the equipment will invalidate any warranty claim.

• Dust regularly with a soft cloth or soft brush but be careful when using cleaning or polishing agents - they
may harm the surface finish.

The electronics in modern hi-fi equipment is complex and may, therefore, be adversely affected or damaged by
lightning. For protection of the audio system during electrical storms, remove the mains plugs.

If after-sales service is required, to help the dealer identify the M6PRX please quote the serial number located
on the rear panel of the unit.
