I want to record some mechanical sounds on my Stargate to use in the game I'm working on in Future Pinball. So obviously, I need to disconnect the speakers to eliminate buzzing and game noises. So, although I'm pretty sure it's okay, I'm one of those people that needs a solid answer before trying something I'm unsure about. Is it okay for me to play with the speakers, DMD, and etc. unplugged? And where do I disconnect the speakers? (See pic of the two sound board below)
