User manual KLIPSCH KSW50

[. . . ] 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. Please take the time to fill out the enclosed questionnaire and warranty registration card. [. . . ] When connecting to a component that has only a single pair of preamp outputs, "Y" adapters (splitters) may be used to feed a signal to both the subwoofer and the power amplifier. If your electronics provide you with a mono subwoofer output and you will not be connecting an LFE channel, you can use the "LFE IN"/"SUB" jack and a single interconnect cable to connect to the subwoofer. Note: Since the KSW 50 lacks a "LFE IN"/"SUB" jack, you can connect the mono subwoofer output jack on your electronics to either the left or right channel "LINE IN" inputs. However, there is a significant (6 dB) increase in subwoofer volume if a "Y" adapter is added to the mono subwoofer output of your electronics and both the left and right "LINE IN" jacks are fed a signal. 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. In situations where the main speakers are being sent a high pass filtered signal (bass frequencies removed), the subwoofer's low pass control should initially be set near the frequency where your main speakers are being filtered. 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. 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. This creates a dip in the bass response since neither speaker is covering this band of frequencies. [. . . ] Install the female end into the recessed socket on the right-hand side of the amplifier panel. To eliminate a tripping hazard, this cord and all other connections should be unplugged from the back panel of the subwoofer if it is being moved. Note: The 230 volt KSW50 and dual voltage KSW 50, 100, 150 and 200 export versions are not supplied with an AC power cord. Since your KSW subwoofer has an internal power amplifier, it must be plugged into a nearby AC wall outlet. [. . . ]
