Combining 9V to get 18V

Post by JRMMD » Fri Jun 30, 2017 2:11 pm

The manual for the 2 Plus says you can combine any 2 9V to get an 18V using the PPY cable. Can you combine the "sag" outlets for this or does it have to be any of the other 9V outlets? Could you use the two "high voltage" 9Vs to create the 18V? I am just trying to determine if this power supply will meet my needs or if I need to get something else. I have 4-9V pedals and 2-18V pedals. Also, I think I read somewhere where all of your pedals together cannot exceed 100mA. Is this correct?

Thank you. I tried searching for a solution but nothing came up.

You can combine any to outputs using our doubler cable... The outputs are isolated so it just adds the voltage of the two outputs together when wired in series this way. It is most common to combine two 9V outputs to get 18V, or two 12V outputs to get 24V. You can use the SAG outputs, but the final voltage will depend on where the SAG knob is dialed to if the SAG feature is enabled.

On a Pedal Power 2+, outputs 1-4 and outputs 7 & 8 are each capable of providing up to 100mA. Outputs 5 & 6 are each capable of providing up to 250mA.

If you list the exact pedals you will be powering we can try to suggest the best route for your exact setup.

I hope that helps!

Thanks. Pedals are:
Boss DD-7
Boss RC-3
Wampler Plexi Drive Deluxe (18V)
MXR Prime Distortion
Whirlwind Selector (for amp channel selection, not in pedal chain, power only)
So I have 4-9V and 1-18V.

A Pedal Power ISO-5 would fit this setup perfectly.

Thanks, that's what I was thinking.
