Switching between LT alignments
I've started a thread in the loudspeaker forum about having multiple Linkwitz transform circuits in one active loudspeaker/subwoofer. The thread is here
I do believe it could be of some value to have different alignments available for different listening situations. But I'm a little blank when it comes to switching between these alignments.
How could this be done? You solid state guys seems to more used to relais than the folks in the loudspeaker forum, and that is the reason why I'm asking here to. The easiest solution would to have a circuit for each alignment rather than changing component values, and it would probably be cheaper too. The opamp choice is less critical in the bass region.
What I'm asking for is how to make a relais based circuit that can switch the transform circuits on/off at both the input and the output of the circuit (which I guess is nessecary) and also give a LED readout. The user input could be either one or as many buttons as alignments.
