what approqch to build an n-way speaker switch

Hi there

I remember as a kid in the department store (John lewis) they had a speaker audition system. You could press buttons 1 to 12 and compare all the different speakers. It was probably just push buttons i guess but it seemed magical at the time.

Many years later I was wondering how to build such a switch and how to control it.

I assume relays are needed for the speaker selection and if I wanted to have in theory many connections then I would need to either drive the relays from radio push buttons that pop out when another is selected or perhaps better to do it via some encoder? maybe a rasp pi to allow for remote control.

The end goal is to create a speaker evaluation system for guitar amps where you can be at one end of a room and flick between different combos of speaker. I guess valve amps introduce an element of complexity to the project.

Perhaps a product already does this?

Love to hear thoughts or ideas on the approach.
