Hello,Please verify that the LineL2+ and LineL2- can be used as a 2.2K condenser microphone input.
Thank you,
Gary
HI Gary,
Your schematic is too small to be readable so I can't comment on it specifically. In general, the inputs can be used for any signal that doesn't exceed the input range (1.4 vrms differential). Inputs should be ac coupled to allow for proper biasing. There is quite a bit of gain available in the PGA so most mics should work.
