Instructions for use

Thank you for purchasing the Musical Fidelity M8 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 M8 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 M8 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.

REMOTE CONTROL HANDSET The universal remote control shown below enables functions from this and related units to be operated from a convenient distance. Equivalent buttons on the remote control have the same functions as those on the front panel of the unit. Other functions are only available by remote control. As the handset uses an invisible infra-red light beam, the front edge must be pointed directly towards the receiver window at the front of the player, without visual obstruction between them.

OPERATION Starting Once all connections are made, switch on the unit, using the POWER button front of the unit. The MUTE LED will light. Outputs are muted for about 6 seconds, so no sound will be heard. Once the 6 seconds is up the MUTE LED goes out, indicating unit is settled, and ready for use. Volume The volume should be adjusted for normal listening levels. This is done by turning the volume up/down knob on the front panel.

OPERATION TAPE input To use the TAPE input, connect external source to the TAPE input (see page 7). Select TAPE input by pressing the TAPE button so TAPE LED is lit. Selecting the TAPE input can also be achieved by pressing the corresponding button on the remote handset (see page 8). BALANCED 1/HT input To use the BALANCED 1/HT input as a standard input, connect balanced source outputs to the BALANCED 1/HT input XLR sockets (see page 7).

PROBLEMS? Basic problem-solving with an amplifier is similar to troubleshooting other electrical or electronic equipment. Always check the most obvious possible causes first, such as the following examples: Problem Probable Cause Remedy No power when POWER button is pressed. Mains power plug is not fully inserted into rear socket. Plug in securely. No sound Mute function is still active.
