nineback Posted February 18, 2002 Share Posted February 18, 2002 Hello , I bought a KSW 100 subwoofer from the PX in Germany. It is 220V. Is there a way to adjust the voltage to 110V so that I can use it in the US? Quote Link to comment Share on other sites More sharing options...
Guest BobG Posted February 18, 2002 Share Posted February 18, 2002 Check on the amplifier panel at the fuse holder. If you see two fuse values/voltages listed, it's a dual voltage unit. If so, there is a red switch inside the amp near where the power cord comes in. One direction for 220 and another for 110. If you do not feel comfortable opening the unit, STOP and get help. Make sure the unit has been disconnected from power for at least 24 hours before opening. Quote Link to comment Share on other sites More sharing options...
kenratboy Posted February 19, 2002 Share Posted February 19, 2002 I have a Jamo sub I bought in the U.K., and although there was NO switch, I was able to get a volt-ohm meter on the power outputs of the transformer while it was turned on and find that one of the power outputs was indeed 120 volts, as opposed to the factory set 240 volts! I WOULD NOT recommend this to an amature or someone with bad luck, but it is a real good way to save the replacement or new parts on a sub. Again, it isn't an OSHA-approved method, but if your not a wuss, it should work. Quote Link to comment Share on other sites More sharing options...
