Pearl Nano User Guide Connecting microphones to the XLR line level inputs

To avoid unwanted signal noise on the RCA ports, we recommend adding no more than 12dB of gain to the RCA
port or when XLR/RCA is used.

Connecting microphones to the XLR line
level inputs
The XLR analog audio input ports on Pearl Nano 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 Nano, you must
use an external preamp and boost the mic level signal to the appropriate line level before connecting it to
the XLR port.
