Hi there,
I'm building a preamp and will be using relays to switch the inputs. Are there any best practices I should follow to minimise input crosstalk? Grounding etc?
I've seen designs that use a large resistor to signal ground on each signal input and others that don't.
Thanks.

Andrew, you are a very knowledgeable chap, but you aren't half a rude so and so some times. Was there any real need to post that?
I did search. Just for the wrong terms it seems. I actually spent 30 mins trawling through non-relevant stuff before posting. But thanks for your helpful input in any case.

that's a usual precaution against dc over the relay contact, making switching 'pop- or clickless'. Otherwise a capacitor coupled floating source would charge the coupling cap over the contact.sjalloq said:
