I live in Australia and bought a Boston XB6 sub from USA, expecting it to have a voltage selector on the back panel to switch to our local voltage of 230 volts, which it does not. I looked at the inside of the amplifier module and saw on the power supply board two jumper connectors with positions marked for 120v and 230v. If I change these to the 230v position is that all that is required to operate it on 230 volts?

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.
The voltage in Greece is 220volts and in USA is 120v. Now depending on where you bought it from there might be a voltage selector at the back ( near or inside the battery compartment you will find a slide switch - you will have to use a flat blade screwdriver to change voltage). Mostly only Asian models have 120/220v selector because Japan is 120v and the rest of Asia is 220. Another way to find out if its multi voltage, check the sticker or engraving at the back it will be mentioned on it.
hello. The electrical power used in most of Japan is very similar to that of the USA. The difference is that Japan uses 100 volts as opposed to our 110. Therefore, most electrical appliances, blow dryers, etc will work equally well in Japan and in the USA.
Since you are in Australia now, use the same adapter for your expresso machine as you use for other small appliances and you should be fine.
If you look at the power lead, you will notice it is the regular "kettle plug" shape, but it only has two pins (live and neutral). There is no earth connector.
You have to ground the sub to your receiver. This is done by running a RCA connector connected to one of the unused connections to the amp.
However, this doesnt ALWAYS solve your problem. As in my case. I have a Pioneer 7.1 receiver, which is ALSO not grounded. so running a spare RCA cable has no effect. What I have done is wired a RCA connecter to a copper cable and connected the other end to the Earth pin on a 3 prong plug. This is plugged in to a wall socket, thus grounding the sub.
It's not a solution the manufacturer will suggest, but it seems to work for me.
You didn't say is your sub active or passive.If its active first check signal cables from theater system,power line of the sub, it has to be the same phase as the system.If its passive take a voltmeter disconnect the sub from the system and measure for DC voltage on the SUB output on the system when its OFF.If DC voltage is present your amp is damaged.It can also be that the preamp circuit for the sub doesn't mute the input when unit is on stand by and you hear frequency of your power supply (50-60Hz) on the sub
