INSTALLATION
Introduction
Congratulations on the purchase of the new M8s 700m power amplifier. Great attention has been paid to internal
layout, isolating each circuit section to prevent possible interaction.
The unit features two monoblock high current amplifiers with paralleled supplies for the absolute best in
transients and dynamics. Generously rated, they are enough to drive even the most demanding loudspeakers
with ease. Low distortion and very quiet they will deliver all music types exactly as the artist originally intended.
The resultant performance achieved by this unit is among the best in the world. It has excellent signal to noise
ratio, low distortion, wide bandwidth and dynamic range, with extraordinary resolution and fine detail.
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 M8s 700m 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 significant quantity of power at all times, and it is
important that it is adequately ventilated. The top and bottom are ventilated to allow the smooth
flow of heat through the unit. It is therefore not recommended that the unit is enclosed in a
cabinet or placed where the ventilation holes are impeded as this could result in excessive heat
build-up.
The M8s 700m 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.
Power Connections
The M8s 700m is supplied with a standard IEC mains cable which plugs into the IEC socket at the back of the
unit (see page 7)
Audio Connections
XLR Inputs: Connect any XLR balanced source to balanced analogue input (see page 7 for more information).
Use good quality fully connected (signals and ground) balanced XLR cables for all XLR signal connections.
The balanced input and outputs sockets are fully balanced, i.e. there is signal on both hot and cold signal
terminals. Please ensure for maximum benefit, that any balanced leads used with this product are fully
connected both ends and that the cold lead is separate from ground connection. Consult lead manufacturer if
there is any doubt.
RCA Inputs: Connect RCA single-ended source to relevant analogue input (see page 7 for more information).
Use goo
d quality fully connected (signal and ground) coaxial phono cables for all RCA signal connections.
SPEAKER OUTPUTS: Connect loudspeaker(s) to the terminals on the back panel marked as SPEAKER
OUTPUTS.
LOOP OUT: loop outputs (XLR and RCA) allow the input signals to be passed on to a second amplifier, or other
component. This is useful for example, for bi-amping.
Cables note: Musical Fidelity currently do not make any interconnecting cables, nor do we endorse any
particular third-party manufacturer’s cables. If advice is required, please refer to the Musical Fidelity dealer who
can demonstrate suitable quality cable(s) for any particular setup.
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 M8s 700m 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 M8s 700m PWR then becomes the main controlling device and
its power button will automatically switch on/off all devices thus connected to the trigger output.
