Using a BeatBuddy Mini 2 without an instrument

This should be a simple question… I typically use my BBM2 with my guitar running through it which means it goes through my guitar amp. I would rather run it through my p.a./vocal amp to get a better sound, as recommended in the user guide. In order to do that is there a way to switch it on other than plugging a loose patch cable into the input?.. Scratch that… just a loose cable in the power line… all good

Perhaps something like this?
