A Banana Jack Question... |
|
|
Hi all. I've been making noise boxes and things for a while, but finally decided I want to experiment with some different things and make it modular. I have a question about banana connections (or maybe I need something else...read on...)
One oscillator I like to make is with the 4049. Previously I would make it with a switch so I can either have it controlled by another 4049 oscillator to modulate it, or just so it gets the power from a constant source and doesn't modulate. This all works fine. Now I'm considering making it modular so I can plug the LFO into any of my oscillators, and what I'm wondering is; how can a banana plug disconnect what's already connected? So when I plug the LFO in, this takes over and the constant power source is bypassed. Is this even possible? Would I instead need to select either the constant power or the LFO and plug whichever I want in?
Am I even making sense?
Any help is appreciated!
David. |

and now the bad news...
I don't think there are switching banana jacks unfortunately. You would need to use an actual switch to select an internal or external source (LFO, clock etc).
That would be a useful thing to invent and manufacture. Probably sell quite a few of them I imagine. |

Yeah, I figured as much, and you know what? It's cool! I was just worried I was missing something. As it is, I'm quite happy to know I can press on with my ideas without stressing that I've made it unnecessarily complicated!
Thanks for the reply! |

With banana jacks, if you really want to stick with just banana jacks, the easiest way would be to put a small switch right next to it, or between two banana jacks.
This was the main reason I decided to go with 6.5mm phono plugs. When you're pushed for space, it makes sense to use a jack which (can have) this function built in to the (almost) same size component.
I'm not dissing banana jacks, their simplicity, flexibility and reliability are major bonuses over phono cords.
I think it just comes down to personal preference.
Remember you can combine both, if you do it right, but it's probably easier if you make a commitment to one or the other from the start. _________________ What makes a space ours, is what we put there, and what we do there. |

With phono plugs, you can get switchable jacks, correct, which switch when something is inserted? |

Yep,
You wire them as "normalised" connections.
So when a plug isn't inserted, the input is connected to something else. This could even be another jack. You can create multiple inserts this way.
Admittedly, doing this for all the inputs on a Lunetta style instrument is just not feasible, both from a space, and expense point of view. _________________ What makes a space ours, is what we put there, and what we do there. |
