These connections will provide full-range sound to all four transducers, and you should ALWAYS make these connections. If your receiver or amplifier does not have a line-level subwoofer output, then you do not need to make any other connections, and you should skip to the section titled "Amplifier Controls. " LINE-LEVEL CONNECTIONS RECEIVER/AMPLIFIER SUBWOOFER OUT Y-Connector (not included) LEFT RIGHT LFE IN LFE IN LEFT S412PII Each S412PII speaker is also equipped with a line-level Low-Frequency Effects (LFE/Subwoofer) input for superior performance with digital surround formats. The . 1 LFE channel contains additional low-frequency information not found in the left- and right-front channels. The LFE input works with the full-range speaker-level input to provide the dynamics and effects that your favorite filmmakers intended. You will need to use a Y-Connector (not included) with one male connector and two female connectors to connect the line-level subwoofer output on your receiver/amplifier to the LFE/Subwoofer inputs on the S412PII speakers. Plug the male connector into the subwoofer output on your receiver or amplifier, and connect each of the two female connectors to RIGHT S412PII extension RCA patch cords. Then plug each patch cord into the LFE/Subwoofer input of the left and right S412PII speakers. Note: If your receiver has separate left and right line-level subwoofer (or LFE) output jacks, you do not need to use a Y-Connector. 5 AMPLIFIER CONTROLS LFE Level Control: Allows you to adjust the volume of the low-frequency effects/ subwoofer channel to suit your room acoustics or tastes. However, it only affects the LFE signal. If you are not using the LFE input, the LFE level control will not operate. Configuring Your Receiver: You should choose the "Large" or "Wide" option for the left- and right-front speakers so that full lowfrequency information will be sent to the S412PII speakers. Make sure that you also configure your receiver for "Subwoofer On" or "LFE On. " In this case, the LFE/Subwoofer signal will consist only of the . 1 (bass) channel.
