Volume Control
Part Number: 2519875Gateway KAS 303 Home Theater in a Box

Volume Control Rotating this knob clockwise increases the output level of the subwoofer. To start out, make sure that the volume is turned all the way down (fully counter-clockwise). Later, after some initial listening tests, you can adjust the volume to your own tastes. However, care should be taken not to overdrive the subwoofer to the point of audible distortion.
