Remember to maintain polarity by connecting the positive (+) terminal on the receiver/amplifier to the positive (+) terminal on the HKSUB 12 subwoofer, and the negative (-) terminal on the receiver/amplifier to the negative (-) terminal on the HKSUB 12 subwoofer. ™ Speaker-Level Outputs: If you are using the Speaker-Level Inputs ¡ on the HKSUB 12, connect these binding post terminals to your front left and right speakers, remembering to maintain polarity by connecting the positive (+) terminal on the HKSUB 12 subwoofer to the positive (+) terminal on the speaker, and the negative (-) terminal on the HKSUB 12 subwoofer to the negative (-) terminal on the speaker. If you are not using the Speaker-Level Inputs ¡, connect your front left and right speakers directly to your receiver or amplifier. See pages 12 through 15 for further information on speaker connections. £ Line-Level Full-Range Inputs: Connect the full-range, unfiltered line-level subwoofer output or preamp output(s) of your receiver or amplifier to these inputs. If your receiver does not have a separate subwoofer output, use a Y-adapter (not supplied) to bridge the receiver's preamp output to the main amp input for that channel, and connect the long end of the adapter to the corresponding line-level input on the HKSUB 12. If your receiver has only a single subwoofer output, you may connect it to either the left or right line-level input on the HKSUB 12, and no Y-adapter is needed. ¢ Line-Level Subwoofer (SUB) Input: Connect the filtered subwoofer output of a receiver to this input. This input bypasses the HKSUB 12's internal crossover circuitry, and should only be used with a filtered signal. If your receiver does not have a filtered subwoofer output, you should use the LineLevel Full-Range Inputs £ instead. HKSUB 12 AMPLIFIER PANEL CONTROLS AND CONNECTIONS 7
