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 -

    I'm curious. What is your application?

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

    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.
