Hello,
A part of my diy bluetooth and ir remote controlled soundbar project involves replacing bass boost switch on preamp section of amplifier with a relay that will be controlled by arduino.
Now my question is: Is there something that I need to be carefull about when choosing relays? I know that it must be mechanical and not solid state that is not made for audio.
But are there any other things that I should consider?
I will try to get smallest relays possible for pcb.
Thank you

Hy, thank you for anwser. I was at the shop earlier and they only had Schrack Austria relays for 220vac.
So I took those. Will try with them and if I get noise I will order as you suggested.

I can confirm that SCHRACK RT114012 relays aren`t causing any noise. I had problem with wires coming from preamp to relays picking stray noise, buzz. Solved the problem by insulating them with tin foil and closing them up with heatshrink tubes, connected insulation to gnd.
