Mutiplexing high current?

Hi kids,

I have a number of audio amplifiers (16) that I need to individually multiplex
to a single output.

Unfourtunately, because of the situation, I cannot multiplex the unamplified
signals to a single amp using an ordinary analog mux. I have to have 16
separate amps and multiplex the *amplified* signals. The amps put out 2.5
watts at 1.3 amps.

Is there such a thing as a power mux? Or do I have to use power transistors?

Thanks for all replies.

Don

Don -

I'm curious. What is your application?

Not knowing too much about your application, my first instinct would be 16 N.O.
relays.

Good luck.

Use 16 DPDT relays that are suitable for the power required. You can switch them
by either using a 16 pole rotary switch (you can do the search), or design a circuit
that uses 16 pushbuttons to latch each of the relays.
