Gain Adjust: When changing microphones or users, it may be necessary to adjust
the transmitter gain based on differing microphone sensitivities and voice levels.
• To adjust the microphone gain, turn the MT dial clockwise to increase the gain
and counterclockwise to decrease the gain.
• If you are using a high impedence source, such as a guitar, it will be necessary to
adjust the GT dial. Using a high impedance source requires a special cable.
