In putting together a scheme for channel assign to bus, I was thinking there might be a benefit to using a JFET vs a mechanical assign, with the aim of making switching quieter.
I am looking specifically at the solo/mute arrangement from the Studer 169 console.
Comparing the approach to channel assign with the switch is the resistor always connected to bus, and the other end switched between bus and ground with the alternate of using a series and shunt JFET mute arrangement (showm simplified) this seems effectively the same.
You have the advantage of multiple ways to activate the control voltage if desired. I am thinking this should be quieter. Possible disadvantage would be distortion. Are there any big pitfalls to doing the JFET approach?
Thanks
