On/off switch for one small stereo speaker - good idea?
Lars wrote:
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. -- Return address is VALID. 500MHz Tek DSOscilloscope TDS540 $2100 Wanted, 12.1" LCD for Gateway Solo 5300.

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. |
