European subwoofer, says 100~120v 60Hz, 220~240v 50Hz?

[Lawfer]

There is also a red switch behind, to switch it from 230 to 110 I assume.

Does that mean I have been using my subwoofer with diminished performance (50Hz) because of Zeropean electricity?

that doesn't affect the performance and you're correct in having it set to 220v 50hz in europe

you'd probably break something if you set the switch to the other standard

No I never touched anything, but the other day I thought of looking behind it and saw all that, everything was the way it is when it came out of the package, of course switching it to 110 will make it go boom, this is just for people that move to a NTSC region and want to be able to use it there, all they would need to do is flip the switch and change the power cable.

But what I thought of doing was to change the power cable to an NTSC one, hook the subwoofer to a converter and enjoy it in 60hz mode, but you are saying that it does not make a difference?

i'm no expert on audio equipment, but it shouldn't make a difference because the internal psu tranforms the input voltage into whatever the subwoofer works with anyways

Yeah I thought it was weird it would work in a better way depending on the electricity voltage, but with European equipments you never know, so thats why I thouight of asking to be sure, thanks.

In most PAL territories, electricity is supplied at 220 volts at 50hertz AC
and most NTSC territories get electricity at 110 volts at 60hertz AC...

If your soundsystem is supposed to run at 110volts and you plug it to 220volts, it will blow the main transformer (or the entire PSU)...
if its supposed to run at 220volts and you plug in to 110volts, it will just not run properly, depending on how the PSU is built.

internally almost all sound system run at 12volt DC at around 1-2 Amps, the PSU converts low amp high AC voltage to high amp low DC voltage, almost all electronic stuff works on DC voltage internally...

So, just find out what volts you wall plugs deliver, switch the system to that volt, then enjoy some music.

In the case of your subwoofer, the hz it runs at power wise makes no difference to the performance of the unit.

Audio is measured in hz as well, but it means something completely different.

Its strange that you think 60hz power is better than 50hz power

[Ed Oscuro]

There is a difference in efficiency, but nothing to get excited about, I'm sure, and certainly no danger.

Do you like playing video games that are 17 percent slower, with a compressed screen ratio and two black bars up and down? Me neither!

[Ed Oscuro]

Actually in this case he's pretty much right - timing of most all computers is not based on the current frequency coming out of the wall. Analogue clocks and maybe some other motor-driven devices may run faster or slower on the wrong frequency power.

The rate at which the current alternates doesn't seem to be the big deal when comparing power standards - rather the frequency, which is double that in 240V land compared to 120V. It's more dangerous if you get shocked, but more efficient for electric devices.

North Japan has 50Hz, while South Japan has 60Hz

I mean this in the friendliest way possible - I hope this was sarcasm. If not, reread what nasty_wolverine said and then have a google about alternating current, direct current and transformers. Admittedly the utility in correlating timings can be a little confusing/misleading - and if nothing else globalization has been good for best practices in computer games

In general, for a power supply, if there's a switch, never switch it to the wrong region to the one you're in - it will probably blow something. There are many an appliance that can work out what supply they're connected to, but there's probably more that simply come with a modular piece fitted, and a plug, that's just for the specific region they're sold in...
