Introduction
Congratulations on the purchase of the new M1 PWR. This unit will give top quality performance when used as
a top quality power amplifier, delivering the best performance possible from any source.
Cleaning
Before cleaning the unit, switch off power at the mains switch and remove the mains plug from the wall socket.
Clean the cabinet and remote control unit using a moist cloth. Using solvents, white spirit or thinners is not
advised, as they could damage the surface finish.
Installation
Position the M1 PWR on a stable, horizontal surface where there is no risk of it being knocked, or subjected to
vibration such as from loudspeakers.
Important note:
In normal operation, the unit dissipates a quantity of power at all times, and it is important that it
is adequately ventilated. The M1 PWR must be protected from humidity – if the unit is moved from
a cold place to a warm room, leave the unit for an hour or so to allow sufficient time for the
moisture to evaporate.
Please note: Musical Fidelity currently do not make any interconnecting cables, nor do we endorse any
particular manufacturer’s cables. If necessary, please refer the dealer who can advise on quality cables for any
particular setup.
Power Connections
The M1 PWR is supplied with a standard IEC mains cable which plugs into the IEC socket at the back of the
unit.
Output connections
Binding post outputs:
Use good quality speaker leads for absolute optimum sound quality.
RCA loop outputs:
Use good quality RCA phono audio cables (fully connected signal and ground), for
optimum signal transfer.
The LOOP OUT sockets pass on the INPUT signals totally unaffected. They are in fact directly connected to the
INPUT RCA sockets to allow reconnection of further amplifiers/active subwoofers etc.
Input connections
LINE (RCA) input:
Connect line level source to LINE input socket. Use good quality RCA phono audio cables
(fully connected signal and ground) for optimum signal transfer.
This input accepts LINE signals from any hi-fi volume-controlled source. It may be connected for example to the
stereo outputs of an M1 CLiC (pre-outputs), or other pre-amplifier.
Trigger connections
Trigger input:
Connect trigger output of controlling device to input socket. Use good quality 3.5mm jack cables
(fully connected signal and ground) Unit accepts ±4 to ±15V DC trigger inputs. The M1 PWR can then be
switched on or off by remote device(s) connected to its trigger input.
Trigger output:
Connect trigger input of controlling device to output socket. Use good quality 3.5mm jack
cables (fully connected signal and ground). The M1 PWR then becomes the main controlling device and its
power button will automatically switch on/off all devices thus connected to the trigger output.
