View Full Version : 240v mixer to 110v?
16th October 2002, 12:52 PM
I was considering buying a PAL mixer (Panasonic MX10) from the APT guys while I was over....we tried it with the Rebelle and found it actually worked quite well for the beast because it has no TBC and just takes sync from ch.1....however, in order for me to use it here in the states I'd have to swap out the power supply so it works on our juice...it was suggested that the mixer would not work properly if this was done due to the difference in frequency of the power (60hz here vs. 50hz there). The idea being that the mixer bases the timing of its operations on that frequency.
Do any of you have knowledge/experience of this?

Why bother swapping the power supply when you can just spend $20 or so and get one of those power conversion adapters. They sell the low wattage ones at AAA even, or radio shack I'd gather. To the best of my knowledge you can plug in 110/120 VAC and get 220/240 VAC out just like it was coming out of the socket in the UK. This is what everybody did for Videa, except it was the other way around I think....

hmm....I suppose they would make adapters that go the other way, eh? I'll look into it...

i think most of them do both of them stepup and stepdown

I don't know for sure about videomixers but I'm into music and most of my hardware gear don't work with only voltage transformed, the frequency needs to be changed too. One synth of mine won't work properly, it tunes the samples wrong, another won't work at all...
When I'm touring in US I carry a 50 pound big step-up/down transformer which also changes the frequency... (110->240, 60->50, >1000W)
And yes, I've tried RadioShack's little cheap ones... If the gadget doesn't have an autosensor and can't take both 50 and 60Hz, I'm screwed.
My two cents,

yeah, seems like analog/hybrid equipment is affected to the cycle difference between 50 & 60Hz resulting in incorrect timing in the analog circuits.
Most modern electronic equipment including battery chargers, computers, printers, stereos, tape and CD players, VCR/DVD players, etc. will not be affected by the difference in cycles, don't know
about videomixers tho, sorry...

you should be able to open it up and just swap the 230v 50hz power supply with one that suits your US power system - the only thing you need to match is the output power (which is probably just +12v and -12v)
i doubt you'll harm it by using a stepup transformer - it might work and if there only $20 then its worth a go
