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.

OPERATION Switching on. When first connected to a mains supply the orange STDBY LED should light. This indicates the unit is in low power standby mode and that mains power is connected. (if it is not on, check mains wall socket switch is on, if present.) To turn the unit on, press the POWER STBY button once. The orange STBY LED should go out, and the blue POWER LED comes on.

OPERATION Setup (Mono “block” mode) Two units, are hereby required for a stereo setup; one designated for the “left” channel; the other for the “right” channel. Speaker connections Make sure the unit is switched OFF. Check the switch on back panel is in MONO position. Connect the left hand speaker wires to the LEFT SPEAKER OUTPUT binding posts of the left hand M1 PWR unit. Observe polarity of the cables and connections: Connect the + wire to red, the – wire to black.
PAGE 10
OPERATION Bi-wiring (in monoblock mode only) It is possible to take advantage of the above feature to “bi-wire” the outputs to suitable speakers. Such speakers must have at least four terminals; two for the treble, high frequency (or HF) driver and two more for the bass, low frequency (or LF) driver. Any “shorting links” between treble and bass input terminals (on the speakers) must be removed for maximum benefit.

PROBLEMS? Basic problem-solving with an amplifier is similar to troubleshooting other electrical or electronic equipment. Always check the most obvious possible causes first, such as the following examples: Problem Probable Cause Remedy No power Mains power supply is not fully inserted into mains socket Mains power supply lead is not fully inserted into rear socket Plug in securely No sound Wrong connections between input sources and the unit.
