For your records: Model Serial Number Date Purchased Dealer Name 193104 7M0999 LF-10 and LF-12 Subwoofers Owner's Manual & Warranty CAUTION: RISK OF ELECTRIC SHOCK!To reduce the risk of electric shock and fire, do not remove the cover or back plate of this device. The international symbol of a lightning bolt inside a triangle is intended to caution you to uninsulated "dangerous voltage" within the device's enclosure. [. . . ] When connecting to a component that has only a single pair of pre-amp outputs, "Y" adapters (splitters) may be used to feed a signal to both the subwoofer and the power amplifier. Note: When connecting to a mono subwoofer output on your electronics (preferably full range), add a "Y" cord to the subwoofer end of the cable and connect to both line inputs. This will provide a significant increase in the subwoofer's output level when compared to the connection of just one of the "LINE IN" inputs. MAIN SPEAKERS LIMITED RANGE If a bass limited (high pass filtered) signal is to be sent to your main speakers, connect your main channel power amplifier inputs to the "LINE OUT" jacks on the subwoofer. These outputs will remove frequencies below 50 or 100Hz from your main speakers, depending upon the setting of the "HIGH PASS SELECT" switch. This type of hookup reduces distortion and increases the dynamic range of your main amplifier and speakers. LFE/BYPASS IN (optional) This input is used with 5. 1 (six channel) surround sound systems. The LFE channel contains bass effects information that is different than the bass signals present in the other channels to enhance the soundtrack's impact. Connect the "LFE/BYPASS IN" input on the LF-10 and LF-12 to your electronic's designated LFE output jack. The "LFE/BYPASS IN" requires a low pass filtered signal from your electronics (high frequencies removed). Do not connect this input to a full range (unfiltered) pre-amp output. ! Note: The peak level of this signal can be up to 10 decibels louder than main channel bass signals, so caution should be exercised when connecting to this output and initially adjusting the subwoofer's "LFE LEVEL" control. Signals coming into this jack are not affected by the subwoofer's adjustable "LOW PASS (Hz)" filter or main "LEVEL" control. The "LFE/BYPASS IN" will not normally be the only connection to the subwoofer, unless the LFE channel is the only signal the subwoofer will be reproducing. The "SPEAKER IN" and "LINE IN" connections are the primary hookups. The "LFE IN" is compatible with either line level or speaker level connections. BASS MANAGEMENT Most surround sound electronics are equipped with a bass management system that permits the selection of either a full or limited range (bass filtered) operation for each speaker. When using the "LINE IN" or "SPEAKER IN" connections on the subwoofer, configure the main channels of your surround electronics for the "Large" or "Full Range" setting. When connecting to a subwoofer output, defeat the low pass filtering on your electronics, if possible. If this cannot be done, use the "LFE/BYPASS IN" input and let your electronics determine the low pass frequency for the subwoofer (the "LFE LEVEL" control now becomes the primary subwoofer level control). Alternately, you can connect the subwoofer's "LINE IN" input to a subwoofer output and set the "LOW PASS (Hz)" control on the subwoofer to a lower cutoff frequency if desired. Since the specifics of bass management systems vary from brand to brand, consult your Klipsch dealer or the manufacturer of your electronics for more details. Operating Controls LEVEL This control adjusts the volume of the subwoofer relative to your main speakers. Use this control to compensate for room acoustics, subwoofer placement and the sensitivity of your main speakers. This control affects the signals that are connected to the "LINE IN" or "SPEAKER IN" inputs. It does not affect the volume level of your main speakers or signals connected to the "LFE/BYPASS IN. " Suggested control position for initial setup: 10 o'clock. LOW PASS (Hz) This control is a variable filter that controls the upper frequency limit of the subwoofer from 40 to 120Hz. Use this control to compensate for room acoustics, subwoofer placement, type of hookup and the capabilities of your main speakers. [. . . ] If you have any questions regarding the installation or connection of your subwoofer, please contact your Klipsch dealer, or contact us directly at 800-554-7724. Care and Cleaning of Your Subwoofer Your Klipsch subwoofer has a durable vinyl finish that should only require dry dusting or cleaning with a damp cloth. Avoid the use of abrasive or solvent-based cleaners and harsh detergents. Types of Connections Your subwoofer may be installed using either "SPEAKER LEVEL" or "LINE LEVEL" connections; both are not required. The LFE connection, however, is an optional line level connection that can be used in conjunction with either type of hookup. Refer to the "LFE/BYPASS IN" and "BASS MANAGEMENT" sections for more detail. [. . . ]
