So what the heck is this? I’m so glad you asked. It’s like the simplest device in the world.
Something I made a long time ago for tracing signals in a patch bay. It’s literally just a speaker mounted into an altorides box. I don’t know why I decided to put a second input.
It’s not uncommon to be trying to trace a signal. And if you’re not hearing what you’re expecting to hear with a quarter inch patch bay, you could just stick a set of headphones in here. Not enough signal to drive them very hard, but, you’d be able to hear something with a smaller TT type bay.
You can’t do that. I don’t know if you can hear that. But I can confirm the signal flow from point to point and figure out where my patch is broken when something doesn’t sound right.
Suppose I could stick a battery in here and make it louder, but I kind of like it’s a passive device and I wired this up so I could use a Bantam patch or a 3.5 millimeter or whatever.
