CALIBRATE AUTO AND MANUAL GAIN
Calibrate Auto Gain
Aurora Pro’s audio input level should be between -3 - 0 dB for optimal lighting
performance. The audio select status LED color indicates the dB range of a
selected audio input. Refer to the
Aurora Pro Connector Interface
for audio select
LED (SEL) colors and corresponding audio levels.
Aurora Pro has built-in adaptive gain to normalize quiet incoming audio. This keeps
light shows consistently responsive in a variety of volume levels once calibrated.
