2 amplifiers and one set of speakers

hemos · 17th September 2008, 02:13 PM

Could anyone provide me with a design of a switch that could control the inputs of my speaker set from 2 amplifiers?

I am in the process of doing blind tests and I would like to switch from one amp to another easily. I don't want the speakers to be powered by the 2 amps at the same time.

Thanks for your help,
Max

Anyone ever build such circuit with a switch so that someone else can't mess with my system? When I'm using it myself there is no risk of powering both inputs, but I can't always have an eye on it

a single pole change over switch on each speaker lead.
The switch could be manual or relay operated.
