Instructions for use Thank you for purchasing the Musical Fidelity M2si integrated amplifier. The M2si uses our tried and tested ultra-low distortion power amplifier circuitry, which has enough current reserve to drive even the most demanding speakers with ease. A very low noise and distortion, high-quality preamplifier completes the integrated amplifier giving a perfect sound from a compact looking full size unit. The M2si will aesthetically match with present and future ‘M’ series products.

INSTALLATION Introduction Congratulations on the purchase of the new M2si integrated amplifier. Great attention has been paid to internal layout, isolating each circuit section to prevent possible interaction. The unit features a finely tuned and tweaked preamplifier, for smooth sound coupled with low noise and virtually no distortion. The power amplifier consists of two top quality power amplifiers for the absolute best in separation and imaging.

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. Speaker outputs are muted for about 6 seconds, so no sound will be heard from the speakers. 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 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 lights. Pressing the corresponding button on the remote handset has the same effect (see page 8).
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. Mute function is still active. Press the MUTE button on the remote control to cancel.
