Instructions for use

Thank you for purchasing the Musical Fidelity M8 500S fully balanced dual mono power amplifier.

The M8 500S is designed to be partnered with present and future M8 series products. It is, in fact, based on the

Titan design. It features a pair of twin high-current power amplifier sections connected in bridged mono

configuration for the absolute best in dynamics and drive capabilities. Two generous over specified power

supplies also ensure unsurpassed supply noise filtering, transient handling and massive power reserve possible

in a single box power amplifier.

Phase splitting between the two internal amplifiers is achieved using a high performance fully balanced

converter circuit with wide flat frequency response uniform in-band characteristics and immeasurably low

distortion and noise.

Fully balanced as well as single ended inputs are catered for along with loop outputs for both types, to enable

bi-amping etc. Trigger input/output allows the unit to be controlled/controller for switch on/off function.

This combination yields one of the best high-fidelity power amplifiers 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 product or related, please consult the dealer who is there to help and

advice.

SAFETY INFORMATION IMPORTANT! (U.K. only) This unit is supplied in the U.K. with mains lead fitted with a moulded 13 amp plug. If, for any reason, it is necessary to remove the plug, please remove the fuse holder and dispose of the plug safely, out of reach of children. It must not be plugged into a mains outlet. The wires in the mains lead supplied with this appliance are coloured in accordance with the following code: Green and yellow .............................Earth Blue..............................

GENERAL ADVICE Installation, Precautions & User Information This new M8 500S is designed and built to 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 and should NOT be grounded on either speaker output terminal as both red and black speaker terminals are effectively “hot”, i.e. carry high current signals.

ITEM DISPOSAL INFORMATION DISPOSAL The crossed out wheeled bin label that appears on the back panel of the product indicates that the product must not be disposed of as normal household waste. To prevent possible harm to the environment please separate the product from other waste to ensure that it can be recycled in an environmentally safe manner. Please contact local government office or retailer for available collection facilities.

INSTALLATION Introduction Congratulations on the purchase of the new M8 500S power amplifier. Great attention has been paid to internal layout, isolating each circuit section to prevent possible interaction. The unit features two monoblock high current bridged amplifiers with generous supplies for the absolute best in transients and dynamics. With their high output current rating, these are enough to drive even the most demanding loudspeakers with ease.

OPERATION Speaker bi-wiring It is possible to “bi-wire” the outputs with suitable speakers. Such speakers must have at least four terminals; two for the treble, high frequency (or HF) driver and two more for the bass, low frequency (or LF) driver. Any “shorting links” between treble and bass input terminals (on the speakers) must be removed for maximum benefit. These links normally are visible under the speaker’s terminals as gold plates/bars connecting the terminals up in pairs.

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.
