Instructions for use
Thank you for purchasing the Musical Fidelity M8s Preamplifier fully balanced dual mono pre-amplifier.
This preamplifier is designed with high quality control and especially balanced sources in mind.
Two balanced (XLR) inputs take care of balanced audio for the best in signal to noise, transient reproduction and dynamic range from balanced sources. Inside, the balanced signal path is fully maintained, from input to output, with a specially developed dual mono fully balanced preamplifier circuit.
The balanced volume control is a quad laser-trimmed attenuator giving 0.5dB steps of perfect matching, allowing precise stereo imaging and ultra-low noise and distortion. The outputs are also balanced allowing connection of balanced input power amplifiers to realise a completely balanced system from source to speakers.
Units with single – ended (RCA) inputs and outputs are catered for with 6 selectable RCA inputs, and two sets of outputs, one fixed for recording, etc, the other is the main controlled output.
The M8s Preamplifier has been designed to mix-and-match input/output signal types and use the unit as a single ended to balanced (or vice versa) converting preamplifier. It is also designed to allow use of both balanced and single ended 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 M8s Preamplifier 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 M8s Preamplifier is designed and built to provide trouble-free performance, but as with all electronic devices it is necessary to observe a few precautions:
•Heed all warnings shown on the back of the product.
•Only connect the M8s Preamplifier 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 where they are not likely to be walked on or trapped by items placed on them.
•Do not use near water, or place water-filled containers on the M8s Preamplifier, 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 M8s Preamplifier 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 fuses you
can replace yourself. Refer all service work to an authorised Musical Fidelity agent.
* 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 agents - they may harm the surface finish.
The electronics in modern hi-fi equipment is complex and may, 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 M8s Preamplifier please quote the serial number located on the rear panel of the unit.
