Why a stereo input and a mono output?
« on: October 30, 2011, 09:15:58 PM »
This is a something that I've been wondering about after looking at this project. I'm a noob, but I am in my first semester of an electronic engineering degree so I've been trying to learn how different stuff works. I know that plugging a mono plug into a stereo input will short one channel of the stereo jack to ground. I just don't understand why this is needed.

The stereo input jack is used as a switch to control the battery. When a mono jack is plugged in, it shorts together the ring and sleeve connections to ground. This means that you can connect the battery's negative line to the ring, and the circuit ground to the sleeve, and the battery will only be connected when a plug is plugged into the input. This saves battery when you aren't using the effect.

Thanks. I had thought about the battery and what prevented it from draining the other day, but I would never have put the two together.
