I am designing a mic mixer project that will be connected to the output from a wireless recieved (balanced xlr). do i need the circuitry used o the evaluation board, and do i need to use the BIAS voltage? my guess is that the bias voltage is for when a passive mic is used. I am thinking that the output from the wireless mic reciever is already to input if capacitor coupled . Should i connect the + and - each through a 10k resistor , then a 10uf cap into the Neg pos inputs?
