I'm using the output of an op amp (LM308) with a low pass filter (R=4700Ohm C= .01 uF if that helps) to control a SSR (D2w203F) which is controlling a string of Christmas lights. I was wondering if there is anything better than a relay that I could use. I've heard SSR are bad when working with audio signals.
The goal is the make the string of christmas lights pulse to the bass of a song. The input is from an audio cable plug into an iPod.
PLEASE provide datasheet references to components used - RM.
