View Full Version : Can the ISO-5 power an Ethos?
11-05-2010, 07:24 AM
Does the 300mA outlet on the Pedal Power ISO-5 properly power an Ethos pedal? Looking at the specs, it seems that the 300mA outlet is regulated, which the Ethos pedal doesn't like. Anybody try this? Or does the 18v outlet do the job?

I'd like to know too. It still works, so I didn't blow anything, but my Ethos sure does smell weird.

Good question! The Ethos manual says it can be powered w/ the PP2+ in outlet 6 set away from normal. So that's 12V @ 250mA, so I don't see why it wouldn't. The manual is confusing w/ its power requirements, it also states you can run it thru a DC Brick at 18V. The Ethos must have a voltage regulator of sorts, but if it can run thru the PP2+, than it should be alright. The 18V outlet of the ISO-5 does not supply enough mA for your needs. Whereas the 18V section of the DC Brick can power up to 1000mA, provided there are no other pedals powered by the Brick (daisy chain PSU, non-isolated).

The Ethos can work with an external power input over a typical range of 15 to 18 volts. It will draw no more than 50mA at these voltages. As long as the voltage is within this range it does not matter if the supply is regulated or not regulated. The only caveat is the absolute max voltage the Ethos can tolerate is 18.9 volts. Voltages greater than 18.9 volts can damage the unit. Note: the unregulated 12 volt, 500mA adapter supplied with the unit actually generates around 15 to 16 volts because the Ethos load is small compared to the 500mA adapter capacity.
hi Robbie, I've always wondered, if the ethos could be powered by a 9v battery, will it work well if I use something like a 1spot on the battery clip(via a battery clip adapter)?

If you attach directly to the battery clip with clean 9V it will work fine. Note: The external power needs to be higher to account for a voltage drop created by filtering. The filtering is used to remove 60 - 120Hz noise created in case somebody uses a noisy external power adapter.
Okay! That's good to know:) Thanks Robbie!
