I have a Quad Artera Pre which claims to be "old school" analogue, but uses a microprocessor to, I assume, set and control different settings for all inputs and outputs.
How is this done?
Does it control some kind of variable resistance/capacitance components?
Or is it done in the digital domain?
Switching inputs is now done with relays, though. Would be interesting to see a schematic.
