Klipsch 20M0499 warranty Operating Controls

Refer to Figure C. Depending upon the setting of the “HIGH PASS SELECT” switch, these outputs will remove frequencies below 50Hz or 100Hz from your main speakers. This type of hookup cre- ates a bi-amplified system, lowering distortion and increasing dynamic range.

“LFE IN”/ “BYPASS IN” / KSW 15 ONLY

This input should ideally be connected to a low pass filtered LFE subwoofer output jack on your electronics. Refer to Figure C. It is typically used with the newest 5.1 (six channel) surround sound systems. Signals coming into this jack are not effected by the subwoofer’s adjustable “LOW PASS (HZ)” filter. The “LFE IN”/ “BYPASS IN” input and “LINE IN” inputs are summed together so both connections may be used concurrently if your electronics provide you with both outputs. The “LFE IN”/“BYPASS IN” may also be used in conjunction with speaker level inputs.

BASS MANAGEMENT

Most surround sound electronics are equipped with a bass management system that permits the selection of either a full or limited range (filtered) operation for each speaker, including the sub- woofer. When using either the subwoofer’s “LINE IN” or “SPEAKER IN” inputs, configure the main channels of your surround processor for the “Large” or “Full Range” setting. If the subwoofer output on your electronics has a “non-defeatable” low pass filter, set the “LOW PASS (HZ)” control on the subwoofer to its highest setting (120Hz). The dedicated LFE input on the KSW 15 is the exception to this rule. Refer to “LFE IN”/ “BYPASS IN” / KSW 15 ONLY.

The “.1” or LFE (Low Frequency Effects) channel contains a different signal than the bass frequencies present in the other channels. This information can be up to 10 decibels louder than the bass signals in the other channels, so caution should be exercised when connecting to this output and initially adjust- ing the subwoofer's level control.

Operating Controls

“LEVEL” / ALL MODELS

The “LEVEL” 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 effects the signals that are connected to any of the subwoofers inputs. It does not effect the volume level of your main speakers.

Suggested control position for initial setup: 10 to 12 o' clock.

“LOW PASS (HZ)” / ALL MODELS

The “LOW PASS (HZ)” control is a variable filter that controls the upper frequency limit of the sub- woofer. Use this control to compensate for room acoustics, subwoofer placement, type of hookup and the capabilities of your main speakers. The filter is continuously variable from 40 to 120Hz. Proper adjustment of this control helps smooth the transition in the bass frequencies between your main speakers and the subwoofer. Setting the filter too high will cause an overlap in the bass frequencies reproduced by your main speakers resulting in muddy and indistinct bass. Setting this control too low may cause the output of the subwoofer to sound disconnected from the bass range being reproduced by the main speakers. In light of this, we encourage you to experiment with various settings.

If your main speakers are being high pass filtered with an external filter, the “LOW PASS (HZ)” control on the subwoofer should initially be set near the frequency of this filter.

In some cases, you may elect to feed your main speakers a full range signal. In these situations, the “LOW PASS” control should be set near the low frequency limit of your main speakers (typically at the lowest setting of the control with larger, full-range speakers). In all cases, experiment due to vari- ability in speaker placement, room acoustics and associated equipment.

HIGH PASS FILTERING, SPEAKER LEVEL / KSW 12 AND 15 ONLY

If your speakers are connected to the “SPEAKER OUT” terminals on the subwoofer, they are being fed a bass limited (high pass filtered) signal. The “LOW PASS (HZ)” control should initially be set near 100Hz.
