On/off switch for one small stereo speaker - good idea?

Oct 27, 2004 3 Replies

Can you specialists me advise please. I want to be able to switch a small speaker on and off.



The speaker is attached to a small stereo (approx 15W + 15W) which has one speaker in the kitchen and one in the hallway.



Is it ok to simply put a switch in the speaker lead? I am concerned about two things with this approach:



(a) The on/off action may cause transients which may damage the amplifier.



(b) The lack of any load on one channel may cause the amplifier to have a shorter life than otherwise.


Any advice gratefully received. Thank you.


most amplifiers have switches for two sets of speakers that do just that.

Lack of load shouldn't hurt a modern solid state amplifier. But if you're concerned, switch a load of a 20 to 30 ohm, 10 watt resistor in place of the speaker.

Only with a tube amplifier.

You could also put a 50 ohm pot in series.
