Title: Timer for amp
Post by: Bradford "BJ" James on April 27, 2011, 02:23:37 PM

I have a customer who wants to put a timer on a background music system. The easiest way for him to do this is to use a timer on the amp (Yorkville 4040). Apparently he has bought a timer, but it does not shut the amp off. He replaced it with a similar unit hoping it was a bad timer. I haven't seen it. I presume it is a Walmart or similar digital timer. Will a regular HD mechanical timer work for this? I presume the problem has something to do with the size of the amp, and I know some timers cannot be used with certain appliances such as florescent lighting.
TIA,
BJ

Is this a timer that turns off the outlet? Interrupting current to the amplifier will turn it off, no matter how large the amplifier.

Some timers don't utilize actual contacts but rather solid state devices to control the load. The latter are for use with resistive loads and will cause problems with inductive loads. I think this is what's happening here.
