I am going to try to build a speaker controll unit. I want to take one input and go to two outputs that are controllable and switchable. I just want to be able to control volume and on/off of each of them.

If anyone has info/schematics on this, please let me know.

Thanks,
Paul

you mean for home audio speakers?

Shouldn't be too hard really, as far as controlling volume not sure how doing that outside of the receiver would effect audio quality, but there's probably a way to do it. However you might want to checkout ratshack, they might have exactly what you're looking for.

yeah, with one 2.5 mm phone plug in and two 2.5mm phone plugs out, each controlled independently.

you want to make it with phone plugs, not regular speaker wire?

 

[DiamondFire13]

yeah, it is going to be used to controll speakers in two different rooms, they are PC speakers.

Dont worry, one of them is a Klipsch 4.1 system.

Just buy something, to build it would cost more in parts than a commercially available unit.

To control the volume you would need a variable gain amplifier capable of driving the speakers at the maximum desired levels and to split would just be a simple switch.

doesn't the klipsch system for instance have it's own volume control? how about the other speaker set? i can get you a plan to build a speaker switch no problem...it's the volume control that makes it harder

 

[DiamondFire13]

Ahh, I see where the problem lies. I can figure out how to do a switch just fine, I'll do that.

Paul

Thanks for everything guys.

yeah, if you just want to do a switch you just need a radio shack project box, 3 female phone connectors, and a DPDT switch. get some wire, make a common ground between all 3 connectors, and then wire up the positives...should work just fine. let me know if you run into any trouble wiring it up.
