Manual for Windows XP

4. The Wave In window sets the computer-controlled gain or mutes the microphone. The
microphone is monaural, so the Balance control should not be adjusted. The signal is carried
on the left channel. The gain is from -8 dB to +40 dB. The t-bone SC450USB microphone has
very high sensitivity, so the position of the slider should be on the position between the lowest
first and second marks. Set this position too high will cause the signal being cut off or distorted.
