Microphone level amplification
By default, audio volume may be low when recording from the microphone. This can be affected by using a microphone preamplifier integrated into KF extension. Microphone preamplifier is equipped with three switches (SW3, SW4 and SW5). Every switch contains two toggles, responsible for the left and right audio channels. Turning on the toggle will provide the microphone amplification by 20dB.
