COAXIAL inputs
To use the COAXIAL inputs, connect an external source to the COAXIAL inputs (see page 7). Select COAXIAL
input 1 or 2 by turning the Source selection wheel. Selecting the COAXIAL inputs can also be achieved by
pressing the corresponding COAX button on the remote handset (see page 8). All coaxial inputs can accept up
to 24 bit 192 kHz PCM stereo data streams.
OPTICAL inputs
To use the OPTICAL inputs, connect an external source to the OPTICAL inputs (see page 7). Select OPTICAL
input 1 or 2 by turning the Source selection wheel. Selecting the OPTICAL inputs can also be achieved by
pressing the corresponding OPT button on the remote handset (see page 8). The OPTICAL input can accept up
to 24 bit 96 kHz PCM stereo data streams.
USB input
To use the USB input, connect a source to the USB B input (see page 7). Select the USB input by turning the
Source selection wheel. Selecting the USB input can also be achieved by pressing the corresponding
USB/Phono button on the remote handset (see page 8). The USB input can accept up to 24 bit 192 kHz PCM.
For best results from USB input
Check mixer and/or computer volume slider settings are set to a suitable level. Normally “full” or “maximum”
setting of the slider gives the best results. Lower settings can detract from overall sound due to computer’s
internal media player/ mixer attenuation action.
Make sure volume knob on amplifier is turned to usual/comfortable listening position
Select USB input on front panel of amplifier.
Play a piece of recorded music from the computer on preferred media player e.g. Windows Media Player or
iTunes.
LINE OUT
This is a fixed output signal from the input selected. This includes digital and USB. Volume control has no effect
on this output.
It may be used for headphone amplifier (with its own volume control) or recording purposes, for example.
Please note when the amplifier is off this output is disabled along with the rest of the outputs.
Note – the M8xi volume control has no effect on the LINE OUT signal.
PRE OUT (RCA)
This is a variable single ended output signal from the input selected (wether single ended RCA or Balanced
XLR).
This allows the unit to be e.g. bi-amped or used as a preamplifier with external power amplifiers.
Please note when the amplifier is off this output is disabled along with the rest of the outputs.
PRE OUT (XLR)
This is a variable balanced output signal from the input selected (wether single ended RCA or Balanced XLR).
This allows the unit to be e.g. bi-amped or used as a preamplifier with external power amplifiers.
Please note when the amplifier is off this output is disabled along with the rest of the outputs.
Trigger input 3.5mm jack
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 3.5mm jack
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 connected to the trigger output.
