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

Crossover Frequency Control This control determines what lower part of the frequency spectrum will be reproduced by the subwoofer and what higher parts will be handled by your main speaker. It is a "crossover" control. Rotating the knob sets the point where all lower frequencies will be handled by the subwoofer and all higher frequencies will be routed to your main stereo speakers. As a starting point, set the control around 80 Hz. if you are using left and right tower speakers, 100 Hz. with bookshelf speakers, and 120 Hz. with small mini-speakers.

Note: If you use the Sub In connector, the Receiver Type toggle switch must be in the Pro Logic mode for the crossover frequency control to operate.
