Connecting microphones to the XLR line
level inputs
The four XLR analog audio input ports on Pearl-2 are professional line level inputs rated at + 4.0 dBu up to
12.3 V RMS, (+24 dBu). You can't connect microphones directly to the XLR ports because the microphone
signal is too low. If you want to connect microphones to the line-level XLR ports on Pearl-2, you must use an
external preamp and boost the mic level signal to the appropriate line level before connecting it to the XLR
port.
