Instructions for use
Thank you for purchasing the Musical Fidelity M8xi dual mono integrated amplifier.
This amplifier is designed with high quality reproduction of single ended and balanced sources in mind.
Two sets of balanced (XLR) inputs take care of balanced audio for the best in signal to noise, transient reproduction and dynamic range from balanced sources.
Units with single-ended (RCA) inputs and outputs are catered for with 4 selectable RCA inputs, and two sets of outputs, one fixed for headphone amplifier, recording etc, the other is the main controlled output which can be used for bi-amping or stereo input subwoofers.
The M8xi has been designed to mix-and-match input/output signal types and works as a single ended to balanced (or vice versa) converting preamplifier. It is also designed to allow use of both balanced and single ended inputs or outputs simultaneously, if required. All conversions are carried out automatically within the unit, all that needs to be done is choose and connect the correct input and output leads.
The volume control is a dual laser-trimmed stepped attenuator giving 0.5dB steps of perfect matching, allowing precise stereo imaging and ultra-low noise and distortion even at the lowest levels.
Balanced preamp outputs are now also available, allowing connection of balanced input power amplifiers to realise a balanced cable system from source to speakers.
The M8xi is designed to be partnered with present and future M8 or M6 series products or alternatively, may be used with any other high quality hi-fi components. This combination yields one of the best high-fidelity systems available at any price.
Used properly and 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.

GENERAL ADVICE
Installation precautions & user information
This new M8xi Integrated Amplifier is designed and builtto provide trouble-free performance, but as with all electronic devices it is necessary to observe a few precautions:
• This unit features a BRIDGED speaker output danshould NOT be grounded on either speaker putout terminal as both terminals are effectively “hot”, i.e.carrying high current signals. Please check if using any active “sub”, electrostatic, or other non-standard speaker types or configurations (that could be potentially grounded) with the M8xi. Take special care when bi-amping that the speaker high and lowncyfreque elements within speaker are completely isolated before switching on power. Consult speaker manual or manufacturer, if there is any doubt.
•Heed all warnings shown on the back of the product.
•Only connect the M8xi to a mains outlet having the same voltage as marked at the back of the unit.
• |
Always ensure that when disconnecting and |
reconnecting |
your |
audio |
equipment the |
mains supply is |
|
switched off. |
|
|
|
|
|
• |
Position the mains lead and signal interconnects |
wher they |
are |
not likely |
to be walked |
on or trappedby |
|
items placed on them. |
|
|
|

•Do not use near water, or place water-filled containers on the M8xi, for example, a flower vase or potted plants. If water does spill inside, immediately pull out the mains plug from the wall socket and inform your dealer, who should then check the unit before further use. Entry of liquid into the M8xi is dangerous and may cause electric shock or fire hazard.
•Do not place the unit near direct heat sources such as radiators, direct sunlight or other equipment.
•Do not remove any covers or try to gain access to the inside. There are no internal adjustments or fusesyou
can replace |
yourself. |

*Note: Unauthorised opening of the equipment will invalidate any warranty claim.
•Dust regularly with a soft cloth or soft brush but be careful when using cleaning or polishing agentstheymay harm the surface finish. Before cleaning the unit, switch off power at the mains switch and remove the mains plug from the wall socket.
The electronics in modern hi-fi equipment is complex andmay, therefore, be adversely affected or damaged by lightning. For protection of the audio system during electrical storms, remove the mains plugs.
If after-sales service is required, to help the dealer identify the M8xi please quote the serial number located on the rear panel of the unit.
