Power pedal whine...

othomas2 · Post by **othomas2** » Sun May 29, 2011 11:26 pm

So I'm getting a high pitched whine from feeding my RC2. I'm using the out of my Korg Pitchblack to power it.

RC-2s current draw is 50ma and this should handle up to 200ma.

The thing is I'm using a lengthy adaptor cable (approx 1m) to get the RC2 to the other side of my board otherwise all the playbacks will be 'effected'... I have no other power options left. I still need to try a smaller cable to see if theres any difference and try problem solve further.

Using a Diago P/supply and have six other pedals... so I believe it should be alright power-wise.

I can easily live with it but wondering if anyone else could suggest why this might be happening ?

Here's my setup.

Does is still make the whining if you put it in the place of the Memory Toy?

Some pedals just don't play well with others, regardless of the numbers involved, much like the Stereo Memory Man W/Hazarai I used to havre.

I have the same problem with my ehx hazarai and the ehx cathedral when daisy channing. If i use a separate adapter the noise goes away.
I just learned to live with it, because i don't want to carry 3 adapters.

Yep the RC-2 doesn't like to have anything other than its own supply.
Get a virtual battery to put before it and that will sort it out.

Thanks, I was just reading elsewhere the same thing...

Is there any adaptor style cable that could be used instead to isolate this ?

I had the exact same problem and the virtual battery did the trick. but pricey but surely saves some space and weight

I cannot remember entirely, but when I had an RC2 I believe giving it it's own adapter solved the problem, did you feed it a 9V of it's own? Cheaper than a virtual battery, never even heard of such a thing til now. Placing pedals differently sometimes fixes such things, assuming you're willing to change things up.

Thanks guys...

Nah, everything is fixed and bespoke for those pedals... plus don't really want the RC2 on the board anyways.

I use the loop station for song ideas only.

I think my best best bet would be an independent power supply, unless of course I can be persuaded to go for the virtual battery...

Glad i read this thread as i've been having a similar problem with my metal planet,sd-1 and the ds-1 - all with a horrendous buzz,high pitch whine - turns out to be the psa power supply and daisy chain i've been using - tried them all on battery power today and no noise!
