Hi guys!
hope you're all doing well.
I have a problem without the right solution:
I need to design a switching system that can route one mono audio source to three different outputs via a rotary switch.
It needs to be remote controlled (4pin mini TRS cable would be cool), and without the remote connected I need a default routing to one of the outputs.
I just tried a simple relay switching with a 2 transistor opener that had the perfect behaviour but gave me unacceptable switching pops & clicks. I could also imagine a digital switch but would need one that does not require programming.
Classic analog multiplexers/CMOS switches like the CD4066 have too high distortion.
Do you guys have any idea on how to prevent switching pops/clicks or a device (Maxim has some stuff, but all I2S controlled) that would work? VCAs, some transistor circuitry, ICs?
Thanks in advance!
