It allows a seamless transition from the subwoofer to the satellite speakers. Experiment with this adjustment to find the crossover frequency that sounds best with your speakers. When using the speaker-level connections, the crossover adjustment will also limit the low frequencies being sent to your satellite speakers. This means that your satellites won't have to try to reproduce the information the subwoofer is playing. Troubleshooting If you used the high-level (speaker) inputs and there is no sound from any of the speakers, check the following: · Receiver/amplifier is on and a source is playing. [. . . ] · Check all wires and connections between receiver/ amplifier and speakers.
