User manual KLIPSCH KSW

[. . . ] The KSW models provide more powerful amplifiers, all-new driver designs and greater ease of use, making them an incredible value. A Klipsch KSW subwoofer brings that "I'm part of the action" feeling to your home entertainment system in a way few other components can. If this is your first Klipsch purchase, welcome to the fold, if this is an additional Klipsch purchase, we thank you for your loyalty. When it comes to the best in home entertainment, Klipsch is a sound choice. [. . . ] These types of hookups will provide a full-range signal to the main speakers. Refer to the "LOW PASS CONTROL" section for more detail. LINE OUT If a limited range (bass filtered) signal is to be sent to your main speakers, connect the "LINE OUT" jacks to the inputs on the main or front channels of your power amp, receiver or integrated amplifier. These outputs will remove frequencies below 40 or 80 Hz (120 Hz, KSW 50) from your main speakers depending upon the setting of the "HIGH PASS" switch. The "LFE IN"/"SUB" jack (except KSW 50) is typically used with the newest 5. 1 (six channel) surround sound systems (Dolby Digital® and DTS ®). It is a discrete, low frequency effects channel with different signal content than the bass frequencies present in other channels. The information in this channel can be up to 10 decibels louder than the bass signals in other channels, so caution should be exercised when initially adjusting the subwoofer's level control. The "LFE IN"/"SUB" input and "LINE IN" inputs are summed together so both connections may be used concurrently if your electronics provide you with both outputs. Refer to Figures B, C and D(pages 8 and 9). 4 Figure C KSW 300 INPUT PANEL · Main Speakers, Limited Range / Line Level Connections · One Channel Shown / Repeat for Opposite Channel · Optional LFE Connection Shown · Separate Pre-amp and Power Amp Shown / Integrated Components Require Pre-amp Outputs and Main Amp Inputs Figure D KSW 100, 150, 200 INPUT PANEL · Main Speakers, Full Range / Line Level Connections · One Channel Shown / Repeat for Opposite Channel · Optional LFE Connection Shown · Separate Pre-amp and Power Amp Shown / Integrated Components Require Pre-amp or Subwoofer Outputs 9 HIGH PASS This switch selects either "40 Hz" or "80 Hz" as the high pass filter frequency for your main speakers when your system is connected as per figure C (page 9). This diagram shows a separate pre-amp and power amp, but also applies to integrated components (such as receivers) possessing pre-amp output and power amp input jacks. The high pass frequency is the point below which sound will be filtered out. Typically the higher "80 Hz" setting would be used for smaller bookshelf speakers to relieve them of the strain of having to reproduce the deep bass frequencies. If this filtering is being performed via "HI LEVEL" connections, the control should initially be set near 100 Hz (140 Hz, KSW 50). With line level connections, the control's initial setting should be either 80 or 40 Hz (140 Hz, KSW 50) depending on the setting of the "HIGH PASS" switch. If your main speakers are being high pass filtered with an external filter, the "LOW PASS" control on the subwoofer should initially be set near the frequency of this filter. The Klipsch subwoofer's high pass filter has a gentle cutoff so there is still some audible signal content in your main speakers below the high pass filter's frequency. Because of this, the "LOW PASS" control's setting will often be somewhat below the high pass filter frequency. Conversely the acoustical characteristics of your room may dictate a setting slightly higher than the high pass filter frequency. In light of this, experiment with various settings. Refer to the "HIGH PASS" section for more detail. The goal is to avoid setting the filter at too high a frequency, causing an overlap with the lower frequency range of your main speakers. This can create excess bass energy which may result in muddy and indistinct low frequencies. Setting the "LOW PASS" control at too low a frequency may cause the output of the subwoofer to sound disconnected from the upper bass being reproduced by the main speakers. [. . . ] Since your KSW subwoofer has an internal power amplifier, it must be plugged into a nearby AC wall outlet. A three-prong grounded outlet is recommended wherever possible. Note: Avoid extremely long extension cords of small gauge since they can reduce the amount of current available to the subwoofer amplifier, degrading its performance and presenting a potential fire hazard. Types of Connections Your subwoofer may be installed using either the "HI LEVEL" or "LINE" connections, but not both. With both types of connections, your main speakers can be run full range or high pass filtered (bass frequencies removed). [. . . ]
