hi,
You have to check the working voltage of the adapter of you device. If it purchased from US then it will be 110V. I think the Line voltage in Australia is 220V.Also You have to check is there is any input voltage selector in the in its adaptor . If it there you have to change it to 220V. If there is no such selector then you have to buy a 220v to 110v converter .Then connect the out put of that converter to to your device. You can by this converter at any electronic spare part shope near to you. Or you have to by a new 9V 1.3Amps AC adaptor. When you going to by the converter or a new adaptor take the device. If so they will explain you how to connect the converter or adaptor . By changing a fuse you can't change the operating voltage. If The adapter is designed to use in 110V then the fuse will blow. If you change the fuse and make more experiment with it it will make the full system useless.
ok

you SHOULD be able to. Just use Direct Sound in the host tab.

The most likely case is that one of the main output transistors (if which there are many) is shorted. When the protect circuit senses DC on the final output, it will not allow the output relay to come on to protect the speakers from raw DC. With the power removed, you can check between each outputs Emitter and Collector and you will probably find close to zero ohms. From that point you need to unsolder each of the pins of the bad channel until you find the shorted device(s) and replace them.

Depending on the model, there are four around that date, it could be the insert jacks are tarnished reducing the signal flow between the pre amp stage and digital power amplifier. It could be the power amplifier has failed. It could even be customer error in wiring. This assumes there is the correct level of signal entering the input sockets of course.
