Power Requirements

[Will Pick]

After a few weeks of creating voiceprints on the VPDI, it's time to put this thing to work live. I'm building my rig which includes some additional pedals and will power them with the Strymon Zuma. It would be helpful to know the exact power requirements for the pedal. The fixed outputs on the Zuma all provide 500ma, but it also has two selectable outputs with 9, 12, and 18 volts.

I have three guitars with three different pickups and the VPDI is a game-changer. This, in my opinion, is the pinnacle for the team at Baggs and every player out there who's been chasing their instruments' true acoustic tone. Can't wait to see what's next!

Hey Will,
I am glad to hear that the VPDI is working so well for you. I definitely agree that it's a game-changer!

The Zuma is designed for digital pedals so that should work fine with the DI. We usually recommend using the DI on its own power supply for noise isolation, but the Zuma shouldn't have issues.

As for the power requirements, we recommend a 500mA minimum, at 9V. So you should be good to go. If you do experience any noise issues while using the Zuma, let me know.

Hey Caleb,
Thanks for the response. I'm in the process of testing several techniques with both creating voiceprints with various measurement and studio mics as well as a variety of pedals in the EFX loop, including all of the Align series except the EQ. When I have some real qualitative results, I'll be posting them. So far, I've failed to get a negative result, although when using a reference mic, you have to use most or all of the pad on the input. There are some really decent and inexpensive USB mics, many with lightning connectors, which may be useful and provide users a lot of fun and great results to boot.

Stay Tuned,

Will

I love it! Absolutely, let us all know what you find.

I find it quite an exciting experiment. And although I'm writing now, I hope you succeeded. I also own Strymon Zuma and chose it because it is a highly versatile, future-proofed flagship power supply from one of the most technologically advanced pedal manufacturers in the business. It has 500mA per 9V DC output power, as far as I know. Also, at 12V option provides 375mA, and 18V delivers 250mA. It takes a bit of work to put the measures in place, as if you have [URL="https://www.rocknets.com/converter/weight/kilograms-to-pounds-converter"]to convert kg to lbs[/URL] , you need to know when to add or subtract from the intensity to get everything right. Good luck.

I tried a FAME DC 12, which has an 500mA output, but there were serious noise problems. Next was a Palmer PWT05MK2 with a current doubler cable 2x250mA. It worked good, except that the Palmers overload warning light was lighting ... seemed too dangerous to me. Does a Truetone 1 Spot Pro CS6 work? I would like this, because it would fit under my small acoustic pedalboard.

Output 1 and 2 is 9v 500mA and should work fine.

Hi Caleb - Is 500 mA at 9V the absolute minimum current required for the Voiceprint DI? I have an MXR 238 that (among other options) has two 9V outputs at 450 mA. Would one of the 450 mA outputs be sufficient?

I've run the VPDI on 400mA without any issues. So 450 should be fine as long as it's properly isolated power.

Thanks, Caleb!

I use a phone power bank with a USB-to-9v adapter "USB DC 5V to DC 9 Volt USB Power Supply Cable, Max Current 800mAh, Tip Negative Connector, Compatible for Guitar Effects Pedals"" for all my pedals. It works with the Voiceprint just fine. Any problems anyone can see long term in using it? This setup allows me to use pedals with my battery operated PA when I am not near AC power and minimizes set up time at open mics and the like. Does anyone see a problem with this?

[Caleb_Elling]

I replied to your other post. As long as you aren't getting a bunch of noise in the signal, this setup should work just fine.
