AC to DC

[TaySte_2000]

Ok so I think I asked this the other way round once, but apparently the Line 6 M9 will run from a Voodoo Labs AC power supply which is all good apart from thats a very big and expensive supply that I have no other pedals that require it, also it doesn't work on other voltages.

But it did raise the question for me, "How hard is it to turn a 9VAC to 9VDC" so that I might find an international voltage AC adaptor and then just daisy chain it between a few pedals using some sort of adaptor before the daisy chain.

Ideas people?

Sounds like hard work! This may help:

Why not just get a 9VDC power supply that can provide enough current and daisy chain them from that. Its easy to find, 9V is a common voltage.

Because he wants 9v AC and also 9v DC on the same pedal board. I think.

Where does the AC conversion happen in this scenario?

Many power supplies offer AC and DC on the same box. Cioks has some.

You might want to check on the DIago website. Apparently Line 6 products generally run off DC, but have a rectifier built into them to turn the AC power into DC in the pedal. Diago have an adapter that bypasses the rectifier so you can use a normal 9v DC daisy chain with Line 6 pedals. Apparently it works on the modelling pedals - it should work on the M9, but it didn't work on the JM4. That might be because the adapter simply didn't fit.

I think that adapter just reverses polarity - to bypass the rectifier would involve modding the internals of the pedal.

I have done this with a DM4 but was wary of damaging my main pedal by trying it with the M13, also the M13 power supply says 18v on it, but it and a onespot with adaptor for the line 6 jack will power the DM4 so not sure what's going on there.

Correct

Yeah just looking at the AC Rider but does it work at 230v/110v?

Also the fixed power lead is a bit annoying

This might be a goer

Need to find out what the draw is on the M13 I think the power supply is 2000ma

Without knowing the pedal in question, pretty much any device that runs on AC (unless it runs directly off the mains) has an integral recitfier. What this means is that it will happily run of DC as well, as long as the voltage is correct. And the correct DC voltage will be 1.4 times the AC voltage + 1.2 to 1.4 volts.

So if the Line6 uses 9V AC it will very likely run fine on 1.4x9 + 1.4 = 14 volts DC, and you can ignore polarity.

Power supply is 9vac 2000ma so I'd need 9vdc 3800ma? So Gigrig Generator

No, you need 14vdc 2000ma. But there's a built-in regulator in the Line 6, so anything from 12 to 18 volts will probably work.
