GENERAL ADVICE Installation precautions & user information This new M8xi Integrated Amplifier 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 terminals are effectively “hot”, i.e. carrying 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.

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. Outputs are muted for about 5 seconds, so no sound will be heard. Once the 5 seconds is up, 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. Adjusting the volume can also be achieved using the remote handset, using the volume up/down buttons (see page 8).
OPERATION COAXIAL inputs To use the COAXIAL inputs, connect an external source to the COAXIAL inputs (see page 7). Select COAXIAL input 1 or 2 by turning the Source selection wheel. Selecting the COAXIAL inputs can also be achieved by pressing the corresponding COAX button on the remote handset (see page 8). All coaxial inputs can accept up to 24 bit 192 kHz PCM stereo data streams. OPTICAL inputs To use the OPTICAL inputs, connect an external source to the OPTICAL inputs (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.
