This Owner's Manual applies to both models as they operate in exactly the same way. Where relevant in the following text the term "MXI" is used to refer to both models. Both MXI amplifiers can accept up to eight line-level input sources, including two tape recorders. [. . . ] If overheating has caused the protection system to operate, then it will take some time for the heatsink to cool sufficiently to allow the loudspeaker to be re-connected (probably between five and fifteen minutes depending upon the room temperature and ventilation). The amplifier will cool more quickly if it is switched to standby mode. FAULT CONDITION INDICATION The power amplifiers in the MXI2080 and MXI2150 have intelligent loudspeaker protection systems. If a fault occurs in either power amplifier channel it will report the nature of the fault to the amplifier's display ­ as shown in the table below. The channel reporting the fault will be indicated at the right of the display (LCH or RCH). The examples are shown in the table with left channel faults. The table also indicates what action you should take. "Overheat" and "Short(circuit)" faults can usually be cured by checking your amplifier setup and wiring. The other faults indicate a failure within the amplifier so the unit must be returned for service. Action required Make sure that ventilation grilles in MXI's top cover and bottom chassis are not obstructed. Allow amplifier channel to cool - typically 5 - 15 minutes depending upon the room temperature and ventilation - after which the channel's loudspeaker will be re-connected. The amplifier will cool more quickly if switched to standby. When the loudspeaker is re-connected, make sure that the volume is not set too high ­ i. e. that the sound is clean and undistorted. If the sound is distorted on loud passages, reduce the volume setting. If the problem persists return unit to approved Service Agent. Check that load on each channel is no less than 4 (one 4 speaker or two 8 speakers to each channel). Check loudspeaker wiring ­ at both amplifier and speaker ends. Make sure there are no small strands of wire that might be causing a short circuit. If the problem persists return unit to approved Service Agent. Return unit to approved Service Agent. OVERHEAT LCH Amplifier channel has overheated SHORT LCH Loudspeaker wiring short-circuited, or very low impedance loudspeaker connected, or too many loudspeakers wired In parallel to one amplifier channel DC OUT + LCH DC OUT AC FAIL LCH LCH Excessive positive DC output Excessive negative DC output AC power failure to power amplifier channel 68 SYSTEM OPERATION WITH SMART MY-LINK® When used as a linked system (e. g. with CD player, DVD player and Tuner), Myryad products with Smart My-Link®, have a number of extra features that make the system as a whole easier and quicker to use than a normal hi-fi. These include: Start-on-Play (CD/DVD) Press play on the CD/DVD player (or its remote control) and both the CD/DVD player and amplifier will switch out of standby (if necessary) and play the disc. The amplifier will automatically select the CD or DVD source as necessary. [. . . ] · TAPE has been selected with no tape playing. · UK version only: The fuse in the mains plug has failed. Sound in one channel only: · Loudspeaker cable pulled loose. Check all connections, both at the loudspeakers and amplifier. [. . . ]
