Klewless Posted January 17, 2005 Share Posted January 17, 2005 Does anyone have the circuit for a switch to share a common set of speakers with two amps? Reason for the question is whether or not some type of load gets inserted so the amps see neither a short nor an open. Obviously both amps must not be tied together during the switching process. I am assuming that a non-shorting switch is required. I have a switch for one amp to multiple speakers but want one for multiple amps to one speaker. Any help would be appreciated.

Klewless Posted January 19, 2005 Author Share Posted January 19, 2005 I can't believe no one had any input on my inquiry. This is the first time this board has failed me. Quote Link to comment Share on other sites More sharing options...
arfz28 Posted January 19, 2005 Share Posted January 19, 2005 Niles makes a amplifier switch that I think will do what you want. IT is the NILES DPS-1. If you do a search you can find info on it. Quote Link to comment Share on other sites More sharing options...
DrWho Posted January 19, 2005 Share Posted January 19, 2005 An amplifier with no load would be like shorting the outputs...having nothing connected to the amp results in an infinite load and won't hurt the amp. Ratshack makes a simple A/B switch for speakers for about $20...instead of connecting two sets up speakers and one amp, just connect the amp to the speaker outputs and connect your speakers to the amp input on the box.

Klewless Posted January 20, 2005 Author Share Posted January 20, 2005 Thanks for the info. I have to go to Radio Shack anyway, so I'll take a look. My store does not seem to have a good selection of available items, so I usually have to find something in the catalog. Quote Link to comment Share on other sites More sharing options...
Audiokid Posted January 20, 2005 Share Posted January 20, 2005 I beg to differ with DrWho... never, I repeat, never allow a tube amp to operate without a load. I've seen several open output transformers caused by a no-load condition. He is correct with regard to a solid state amp though. -DrDave Quote Link to comment Share on other sites More sharing options...
DrWho Posted January 20, 2005 Share Posted January 20, 2005 Ok, can someone explain to me the physics of having nothing connected to the output terminals of an amplifier? Is it different between Tube and SS? I don't understand how an infinite load could cause any damage to an amp considering there would be absolutely no signal flow. Nothing happens in a circuit that's not complete. Quote Link to comment Share on other sites More sharing options...
