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 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 is lit. Selecting the TAPE input can also be achieved by pressing the corresponding button on the remote handset (see page 8). TAPE MONITOR To record to tape, CD recorder, DAT, minidisk or computer soundcard analogue input, connect the tape out to the recorder line in. Press the input selector button on the front panel or remote control.
OPERATION USB input For the USB input, the LED will flash in absence of digital input signal. When a signal is present, the LED will light continuously. Computer setup for input USB input A good quality USB A to B cable is required to connect the unit to the computer. Plug the B (square) end into the socket in the back of the M6PRE Plug the A (rectangle) end into a free USB socket on the computer.
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.
