Hi:
I'm new and just got my BS2 to blink LED's and read switches thought
the button command. I've got the current and voltage switching thing
figured out via SCR's or relays, but I need some help in regard to
switching line-level audio signals. The relays pop down chain, and
the SCR's require current to pull them down. I don't think the
Opto22 devices will do the trick since they're SCR type devices
(right?). Can someone please point me towards a device which I can
experiment with for this applicaiton? I can bread-board transistors,
etc, so what I am looking for is someone to say "use a garden variety
NPN" or "look at Mouser part number", etc.
TIA, John.

This is what I might consider for this type of application.
