Telonics Volume Pedal Question

[Corbin Pratt]

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?

[Jon Light (deceased)]

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

[Corbin Pratt]

Yes I believe it's 24v.

[Ken Metcalf]

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.

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.

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.

The telonics is 24V center positive DC barrel jack. In order make this work, is you have to have a power supply that can output 24V such a Cioks DC7 pedal board power supply, which has selectable “DIP” switches that will you to select different output voltages on each RCA output power jack. use 2 of the output jacks to double up the Voltage to 24V then you have to have a “Voltage doubler” cable which will be 2 RCA jacks like in the form of a pigtail(if you are using a ciocks DC7) to solder to the 2 pins on a D panel mount DC jack.

Im doing the exact same thing on a temple audio board duo 24 board for the exact same reason, one less thing to plug in. I’m using a quad cortex and a Shure PSM 900 in ear monitor system which will be mounted to my pedal with flat plates screwed into the pedalboard, no Velcro

Good wood audio is a company that can make these cables for you.

Once I forgot my Telonics power supply, and resorted to using one of the daisy chain ends that I use for my other, standard voltage pedals.

It worked just fine; I did not notice any difference at all.

I'm using a GigRig GenX 14 power supply in my pedal board, and the 9v-24v adaptor (Centre Positive) to power the Telonics Volume pedal. The key is to plug it in to the 1000ma option so that you get enough current to the pedal for it to operate properly ... although I still carry the Telonics wall wart power supply in my steel seat as a back up -- it's still so nice to just power it off the pedal board.
