Hey Everyone,

Is there a way I can use my pedal board power supply (Strymon Zuma), to power my Telonics volume pedal? I'm just looking for a solution to have less things to plug in.

Thanks

What is the voltage of your Telonics Vol. pedal power supply?

I'm looking at a photo of a pedal that shows 24VDC, tip positive.

Yes I believe it's 24v.

It looks like the Zuma will only go to 18 V.
You could check with Telonics, but I would say no.

Yes, you can combine two 12V outputs on the Zuma to make 24V.

1. Disconnect the Zuma from AC power. Set both adjustable outputs on the Zuma to "12V".
2. Determine the connector size of your Telonics pedal DC input. Take an UNCONNECTED DC cable that came with the Zuma, NOT plugged into the Zuma. Fit it into the Telonics pedal DC jack. If it fits, the Telonics jack has a 2.1 mm pin. If it doesn't fit, the Telonics jack has a 2.5 mm pin.
3. Get a "Voltage Doubler Reverse Polarity" cable, which has two connectors for the Zuma and one for the Telonics. The Telonics end should be the size you found in step 2 above (either 2.5 mm or 2.1 mm.) This cable will combine 12V + 12V to give you 24V with a current capacity of 275 milliamps, which is plenty. It will also flip the Zuma's center-NEGATIVE output to the center-POSITIVE required by the Telonics pedal. Make sure the cable is a Reverse Polarity model, they also come in straight polarity. Available at Sweetwater, Reverb and other places, brand doesn't matter.
4. Plug in the cables and power up the Zuma.

Mike

Aweseome. I really appreciate it everyone. I'm going to give that a shot.

The Strymon Zuma already has a 24V out, No need for a doubler cable.

Other forums have reported that when Strymon support was asked about this, the replies were always negative. Reasons given included: the 24V output jack is for daisy-chaining to other power supplies, it's not for powering pedals, it's not isolated and will likely be noisy, it has a different connector, if you use it anyway they're not responsible for what happens, and they recommend a voltage doubler cable if 24V is needed for a pedal.
