  • Page 15: Pa2 Operation

    PERATION Master Volume The master volume controls the overall output amplitude of the front/rear/ subwoofer outputs. The control can be set to its full counterclockwise position for zero output or its full clockwise position for maximum output. Fader Attenuates the front or rear outputs for the desired “front stage/rear fill” effect. When set to the rear position, the rear output level is maintained and the front output level is attenuated.
  • Page 16 Subwoofer Volume The subwoofer volume controls the output amplitude of the subwoofer outputs relative to the front/rear outputs. This allows the bass level to be properly matched with the front/ rear speaker system. Frequency Controls The frequency controls are used to increase or reduce emphasis in a specific octave of music.
  • Page 17 The following procedure will set the radio's volume control to a fixed level, allowing the PA2 to control the level of the audio system. • Adjust the balance, fader, and tone controls on the source unit and PA2 to their center positions •...
