Position the M8xi on a stable, horizontal surface where there is no risk of it being knocked or subjected to
vibration such as from loudspeakers.
Try to route mains leads well away from input leads and keep input leads as far away from speaker leads as
possible. the moisture to evaporate.
Power Connections
The M8xi is supplied with a C19 IEC mains cable which plugs into the IEC socket at the back of the unit (see
page 7)
Audio Connections
RCA Inputs: Connect all RCA single-ended sources to relevant analogue inputs (see page 7 for more
information). Use good quality fully connected (signal and ground) coaxial phono cables for all RCA signal
connections.
XLR Balanced Inputs: Connect any XLR balanced source to desired balanced analogue inputs (see page 7 for
more information). Use good quality fully connected (signals and ground) balanced XLR cables for all XLR
signal connections.
USB input:
Connect USB “A” to “B” cable between USB input and computer (laptop, desktop, tablet or any
other suitable USB audio compatible “host”)
.
COAX inputs: Connect RCA digital source to digital input RCA socket. Use a good quality fully connected
(signal and ground) coaxial digital cable, for optimum signal transfer.
OPTICAL inputs:
Connect optical digital source to optical input socket. Use a good quality “Toslink” cable, for
optimum signal transfer.
RCA Outputs: Connect all RCA single-ended power amplifier(s) to RCA analogue outputs (see page 7 for more
information). Use good quality fully connected (signal and ground) coaxial phono cables for all RCA signal
connections.
XLR Outputs: Connect any XLR balanced power amplifier(s) to XLR analogue outputs (see page 7 for more
information). Use good quality fully connected (signals and ground) balanced XLR cables for all XLR signal
connections.
Speaker Outputs: Connect loudspeakers to the terminals on the back panel marked as LEFT and RIGHT
SPEAKER outputs. For most normal passive speakers this bridged amplifier behaves as any other, however: -
NOTE: Both this amplifier’s RED and BLACK speaker terminals carry speaker voltages and currents.
Do not use grounded speakers e.g. some electrostatics or amplified subwoofer “speaker” inputs, as this could
short one half of the amplifier to ground and cause potential damage. Check with dealer or speaker
manufacturer for advice. Take great care when bi-wiring or bi-amping to not cause inadvertent short circuits.
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 M8xi 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 M8xi then becomes the main controlling device and its power
button will automatically switch on/off all devices thus connected to the trigger output.
Please note: Musical Fidelity currently do not make any interconnecting cables, nor do we endorse any
manufacturer’s cables. If required, please refer to the Musical Fidelity dealer who can give up to date advice on
good quality cables for any setup.
