I understand that the stereo jack is used to shutdown the power to preserve battery life but I never use batteries, so was wondering if I can just use a mono and a 9v DC socket? Cheers.
I often use 2 x mono's for builds, particularly if i have no intention of adding a battery or there's no room for a battery. It's also a good idea to use mono's for tight builds like 1590a builds. If you do add a stereo jack, you can always add the battery snap down the track as well.
Yes, I'm a little more experienced now so I just wire everything with mono jacks.. as I never use batteries it makes things a lot easier and as you said, neater
