Here you add preamplifier gain. Normally the preamplifier attenuates the signal from the microphone due to its input capacitance. Hence you should enter a negative number. Negative gain=attenuation. For Norsonic preamplifiers this value is in the range of -0.2 to -0.5 dB. Set this to 0 dB if you don’t know the gain.
