Left Channel Gain

• Options: 0, 6, or 12dB.

• Default: 12dB.

Gain can be added to the ultrasonic microphone signal to increase the recorded signal’s amplitude.

Test recordings should be made to ensure desired signals are being recorded with enough gain, but not so much as to cause clipping distortion. If a test recording shows clipping distortion, lower the gain setting. If a test recording shows a signal that is too faint, raise the gain setting.
