cheap power supply - issues - help!

[richntiff]

Ok, so I'm fairly new to the pedalboard thing. I have an AMPEG SCR-DI, pedal tuner, and a TC Helicon voice live (basically a mic-preamp with some nice eq/de-essing features) I have them all mounted on my new pedaltrain board. I cheaped out and bought an inexpensive power supply made by Caline Audio (or something like that). The Ampeg and tuner both come off the supply at 9v, and the TC helicon runs off the 12volt.

The TC does not have any bass input - it's just the XLR from my vocal mic, then out to the snake.

Plugged it in at a gig for the first time last night - and granted, this venue has limited power options and it seems to be kind of 'dirty' power - but I had a LOT of hum when all three boxes were plugged in and running.

I was able to fix it by bypassing the tuner, going straight in the SCR, and supplying power to the SCR via a separate wall wart power adapter. So, the only thing that ended up running off the pedalboard power supply was the TC Helicon. My trusty Snark headstock tuner kept me sounding as in tune as I ever do...

My question - is this problem going to be solved if I upgrade to a better quality power supply? I'm thinking an isolated one will hopefully cure that - but being a weekend warrior type, I don't want to drop a ton of coin if I don't have to.

Can anyone suggest a good quality power supply that will solve my issue(and hopefully not too expensively)? As I noted above, it does need to have 9 and 12 volt functionality.

Ok, that was two questions...

Thanks in advance!

The SCR-DI requires a 100mA 9-12 VDC supply.. Check !!
The voicelive requires a 1000mA 12 VDC supply (see back of pic). You are massively under-powering it.

Your Caline (Cp-05) will only provide a 500 mA source..

If you want to run the VL off a power supply, you'll need to find one that supports a 1.0A (1000Ma) outlet..
I couldn't find an "integrated" unit with a quick search.. other than a dedicated AC wall-wart

Do the specs on the power supply say the output is AC or DC. You want DC.

You need to add up the current draw from each pedal, see specs, and be sure the supply can well exceed that amount. Double would be a good target.

A cheap DC supply may not be well regulated. This will be a problem.

sorry - it's not the voice live - it's one of the older units. Actually think it's the Voicetone Correct. I believe it takes 12v/300mA. For some reason I hadn't noticed the 100mA on the 12v out on the Caline. The unit seemed to work just fine with that power source however. The only problem I had was with the loud hum when both were plugged into the Caline.

Ok - Voodoo Lab Iso 5? Looks like about my only option. What would be the ultimate would be a rechargeable power tank with 9v and 12v capability - does anyone make one of those? (ok, I realize I just blew my 'keep it inexpensive' motto...)
