The wire which is coloured BROWN must be connected to the terminal which is marked with the letter L or coloured RED. For U.K. customers If the socket outlets in the home are not suitable for the plug supplied with this appliance, it should be cut off and an appropriate 3 pin plug fitted. For details, refer to the instructions described above. Note: The plug severed from the mains lead must be destroyed, as a plug with bared flexible cord is hazardous if engaged in a live socket outlet.

To reduce the risk of shock or fire and prevent short circuits, strictly follow the instructions on page 5 when connecting speakers. 1 1 When the internal temperature rises, this indicator lights blue and purple alternately. If this happen, relocate this unit in a well ventilated place and turn down the volume of the pre-amplifier etc. When a fault is detected, the MX-D1’s protection system activates and this indicator lights red. If this happens, set the MX-D1 to standby mode immediately and disconnect the AC power cable from the AC outlet. If the indicator continues to light red when you re-connect the AC power cable, contact the nearest Yamaha dealer. 2 SPEAKER terminals These terminals are for connecting your speakers. They provide a reliable connection even with really thick cables. Be sure to connect the left and right channels, and the speaker polarities (+/-) correctly. You can connect speakers with impedance of between 4 to 8 ohms. 3 BALANCE jacks If your source component has balanced XLR output jacks, connect them to these jacks using XLR cables. 4 MUTE button You can temporarily mute the output from the MX-D1 by holding down this button. If you need to change any input connections while the MX-D1 is still on, hold down this button while you do it. This will protect your speakers against possible damage due to sudden loud noises, thumps, and clicks. 5 UNBALANCE jacks If your source component has unbalanced RCA jacks (labeled “AUDIO OUTPUT” on the YPC-1), connect them to these jacks using an audio pin cable. 6 UNBAL/BAL switch With this switch you can select the BALANCE jacks or the UNBALANCE jacks. 7 AC IN connector Connect the supplied AC power cable here. 8 RS-232C terminal 9 AMP ID switch 0 CONTROL IN jack q CONTROL OUT jack w POWER/THROUGH switch These are for control expansion.
