Carefully unpack your new speaker system and verify the components against the packing list. In extreme circumstances, items may have become damaged in transit. If any damage is discovered, notify the delivery service and dealer where the system was purchased. Make a request for inspection, and follow their instructions for evaluation. Be sure to keep the product's original shipping carton.

POSITIONING YOUR REFERENCE SERIES SUBWOOFER

Klipsch powered subwoofoers are designed to reproduce deep bass and deliver the impact that makes your movies and music come alive. Typically, optimum performance will result if you place your subwoofer in a corner of the room on the same wall as your front channel speakers (Refer to figures 1 & 2). Please note that room placement can have a dramatic effect upon the performance of your powered subwoofer. Corner placement, as suggested above, will increase the amount of bass output, while placing the subwoofer along the middle of a wall, or out in the room will decrease the amount of bass output. Experiment with a number of different placement options and control settings to find the one that best suits your particular room and taste. When choosing your subwoofer's location, keep in mind that you will need to connect the subwoofer's built-in amplifier to an AC power outlet.

The RT series of powered subwoofer features "Adaptive Room CorrectionTM" This patent pending technology will identify the major acoustic anomalies in the low frequency range of your listening room's acoustics and compensate for them automatically. While the corrected response may at first sound like a reduction in bass quantity, the benefit is a much higher quality bass reproduction featuring audiably faster transient response and more noticeable extension of extremely low frequency program material. (See the "Room Correction" section of this manual).

CONNECTIONS

CAUTION: Turn off your amplifier and your subwoofer before making any connections!

"LINE IN"- Your Klipsch Reference RT powered subwoofer is connected via line level connections only. Use the "Subwoofer", "LFE" or "Pre-amp" outputs of your system's electronics to connect to the "LINE IN" input connections of your subwoofer. Use high quality, shielded, line level cables for these connections (refer to Figure 3).

"LINE OUT" - This pair of jacks can be used as an alternate method of connecting a second subwoofer to your system. Use high quality, shielded, line level cables for these connections.

CONTROLS

All of the subwoofer's controls, and changes to control settings, are accessed through the cursor key pad and display on the top of the subwoofer's cabinet. The only exception to this is the main AC power switch which is located on the rear panel of the subwoofer.

• Use the (UP) or (Down) key to scroll through the list of control options.
• Use the (Left) or (Right) Key to make adjustments to a given control setting
• Use (Enter Key) when the "←" appears on the display to store and recall custom settings or to lock the keypad
• After adjusting the individual control parameters for "Volume", "EQ Mode", "Lowpass", "Lowpass Slope" and "Phase", your settings can be stored in one of Five user memories ("Movie", "Music", "Night", "User 1" and "User 2"). This allows for global recall of all of the above settings to tailor the subwoofer's performance to compensate for differing source material and uses.
• The display backlighting will turn off if no keypad inputs are made for 10 seconds.
• The display will return to the "Volume" screen if no keyboard inputs are made 10 for seconds.
• If the display is in standby mode, the initial button press will turn on the display backlighting. The second button press will initiate a control adjustment or the selection of another mode.
• In periods of low humidity, it is possible that a static electricity discharge to the subwoofer may cause a momentary interruption in the subwoofer's output or changes to the LCD display content. Any display content errors will be corrected when the screen changes modes.

"Volume" - Use the Left/Right cursor keys to adjust the subwoofer's volume level to match the output of your main speakers. Press and hold (or press and release) the Left cursor key to decrease the subwoofer's volume. Press and hold (or press and release) the Right cursor key to increase the subwoofer's volume to the desired level. From this screen press the down cursor key to access other control settings.

"Recall Settings:" - This screen is used to select any one of five user defined memory presets titled "Movie", "Music", "Night", "User 1" and "User 2". Use the Left/Right cursor keys to select the desired group of stored control settings and press the Enter key to apply them. "Settings Recalled!" will then be displayed. During initial setup, skip this screen until all other initial control adjustments have been made. If nothing has been saved

in the selected preset the display will read "Preset Empty." From this screen press the down or up cursor key to access other control settings.

"EQ Mode:" - This screen is used to select two different Bass emphasis settings, titled "Punch" and "Depth". They are designed to complement different types of program material, such as movie soundtracks or music. The "Punch" setting emphasizes the 55Hz region while the "Depth" setting boosts the 30Hz range. A third setting is titled "Flat" which defeats these two settings. Use the Left/Right cursor keys to select the desired EQ setting. From this screen press the down or up cursor key to access other control settings.

"Room Correction On / Off" - This screen indicates whether the "Room Correction" filter, mentioned below, is engaged. Press either the Right/Left cursor keys to turn this function on or off. This screen will not appear if the "Room Correction" function has not been activated, the "Room Correction" calibration was unsuccessful or the user memories have been erased using the "System Reset" function described under the "Save Settings" section of this manual.

"Lowpass" - This screen is used to adjust the subwoofer's upper frequency limit to achieve a proper blend with your system's main speakers. A higher frequency (Hz) is typically used with smaller, bass limited main speakers and a lower frequency setting is customarily used with larger floorstanding models. This filter can be adjusted from 40Hz to 120Hz, as required, or defeated if the low pass filter function is being performed by your system's electronics. Use the Left/Right cursor keys to adjust the lowpass filter. To defeat this filter press and hold the Right cursor key until "Lowpass OFF LFE Mode" is displayed. Refer to your surround processor's owner's manual for more Bass Management information. From this screen press the down or up cursor key to access other control settings.

"Lowpass Slope" - This screen is used to adjust how aggressively the subwoofer rejects frequencies above the low pass filter's setting. This screen is not visible if the "Lowpass" filter above is set to "Lowpass OFF LFE Mode". There are four settings to choose from; "18, 24, 36 & 48 dB/Octave". The higher the number the more the upper frequencies are removed from the subwoofer's output. Use the Left/Right cursor keys to select the desired filter slope. Start with either the 24 or 36dB/Octave setting and adjust from there if required. Adjustment of this parameter can help to optimize the acoustic blend with your main speakers. The proper setting will depend on room acoustics, your main speaker's performance and the placement of the speakers and subwoofer in the room. From this screen press the down or up cursor key to access other control settings.

"Phase" - This screen is used to adjust the subwoofer's acoustic phase to match that of your main speakers. Use the Left/Right cursor keys to adjust the subwoofer's phase from 0^ to 180^ . The proper setting of this control is highly dependant on room acoustics and the position of your subwoofer in the room. After setting the volume and low pass controls, adjust the phase to 0^ and listen to a recording with a prominent, repeating bass line in your intended listening position. Repeat this process with the 180^ setting and use the setting that yields the greatest amount of bass output. If neither of these settings is better than the other experiment with intermediate settings. From this screen press the down or up cursor key to access other control settings.

"Room Correction" - This screen is used to activate the automatic room correction feature. Plug the supplied microphone into the ("MIC IN") jack on the subwoofer's rear panel and place it in the intended listening position. Press the Enter button to activate the test sequence, "Calibrate" will be displayed along with the ascending frequency of the test tone and a bar graph of the sound level (loudness). The subwoofer will measure the room's acoustic effect and compensate for it. When the calibration sequence is complete "Calibration Successful!" will be displayed. If the subwoofer's volume level is too low or the microphone was either disconnected or improperly connected "Calibration Unsuccessful" will be displayed. From this screen press the up or down cursor key to access other control settings.

"Save Settings:" - This screen is used to store all of the above control settings in one of five memory presets ("Music", "Movie", "Night", "User 1" and "User 2"). Use the Left/Right cursor keys to select the desired preset and press the center key to store your current control settings. "Settings Saved!" will be displayed. After the settings are stored in memory the display will return to the default "Volume" adjustment screen. All of the user settings, in the five memory presets, can be erased and restored to their default values by scrolling down to the last "System Info" screen. Press the Right cursor key twice to get to the "System Reset" screen. Press the center cursor key and all user settings will be replaced with the default settings. "Reset Complete" will be displayed". From this screen press the up or down cursor key to access other control settings.

"Disp Brightness" - This screen is used to adjust the brightness level of the display screen. Use the Left/Right cursor keys to select from any one of 4 different brightness intensities. From this screen press the down or up cursor key to access other control settings.

"Power:" - This screen is used to select the "Auto On" or the "Always On" power mode for the Subwoofer's amplifier. Use the Left/Right cursor keys to select between these two modes. When "Auto On" is selected, the subwoofer will automatically turn on when it senses a signal. It will automatically turn off after 20 minutes if no signal is present and the display screen will show "Standby". In the "Always On" setting the subwoofer will remain

on as long as the main A/C power switch on the subwoofer's rear panel is in the "ON" position. From this screen press the down or up cursor key to access other control settings.

"Play Demo" - Use this screen to activate either of two 12 second demonstration programs. Use the Left/Right cursor keys to select the desired demo and press the Enter button to start playing the selection. From this screen press the up or down cursor key to access other control settings.

"Keypad Lock" - This screen is used to lock the keypad and prevent unintentional changes to your settings by other users. After making all desired adjustments press the Enter cursor key to lock the keypad. "Keypad Locked Hold to Unlock" will be displayed. The display will then return to the default "Volume" screen after about 20 seconds. To unlock the keypad press and hold the Left and Right cursors until the display returns to the "Volume" screen. The keypad is now unlocked. It is suggested that you write down all of your settings for future reference in case the keypad is unlocked and your settings are changed by another user.

"System Info Press " This screen is used to access the "System Reset" function to clear all user settings and memories (refer to the "Save Settings" section of this manual). If the "System Reset" function is activated all of the memory presets are erased and the subwoofer's controls are restored to the default settings of - "Volume 0dB", "EQ Mode Flat", "Lowpass OFF LFE Mode", "Phase 0^ ", "Disp Brightness" (highest level) and "Power Always On".

For more information on the controls mentioned in this manual and on the bass management settings of your electronics, see your authorized Klipsch dealer or visit www.klipsch.com.

BACK PANEL FEATURES

"POWER" ON/OFF

This is the main A/C power switch for the subwoofer. This switch must be in the "ON" position for the subwoofer to operate and for the "Auto On" feature to function. Set this switch to the "OFF" position if the subwoofer will not be used for an extended period of time (i.e. vacation).

IR SENSOR - An infrared remote control sensor is included on the rear panel of your subwoofer for integration with A/V remote control systems. The IR codes for this subwoofer can be obtained by visiting www.klipsch.com. A dedicated hand held remote control does not exist for these models.

"USB" - This computer interface allows access to additional advanced features within the subwoofer room correction software. Optional, proprietary Klipsch software and a higher level of technical knowledge are required to correctly utilize this capability. This port can also function as an alternative control

interface with A/V Control systems that can utilize a USB hookup. Please contact your authorized Klipsch dealer or Klipsch Technical support for more information.

"MIC IN" - Plug the supplied microphone into this jack when using the "ROOM CORRECTION" feature during setup. It is recommended that the microphone be disconnected and stored in a remote location during normal use to avoid damage from loud playback levels.

"LINE OUT" - This pair of connections can be used as an alternate connection point for a second subwoofer. Be aware that the signal output from these jacks is effected by the "Volume", "EQ", "Lowpass", "Lowpass Slope", "Phase" and "Room Correction" settings of your RT subwoofer. The advantage of this is the ability of the RT subwooers Adaptive Room Correction function to correct the response the second subwoofer, resulting in a more accurate response. If the secondary subwoofer is connected directly to your system, the RT subwoofer's room correction will react to rather than control the response of the other subwoofer. As a result we recommend the following procedure when connecting a second subwoofer to these outputs.

• Play a signal, such as one of the RT subwoofer's two demo tracks, and set the volume control of the 2nd subwoofer to approximately match that of the RT subwoofer.
• Defeat the secondary subwoofer's low pass setting by selecting the "Bypass" or "LFE" mode or set the low pass control to its highest frequency if these options are not present.
• Set the secondary subwoofer's phase control to 0^
• Run the "Room Correction" function on the RT subwoofer
• As with the initial setup of your RT subwoofer, listen to a track with a repeating bass line in your listening position. Experiment with alternate phase settings on the secondary sub while repeating this track. If one of these alternate settings yields an increased amount of bass, choose that setting and run the RT subwoofer's room correction function again.
• Please note that if either the volume or phase settings on the secondary sub are changed after running the Adaptive Room Correction™ function you will have to run the RT subwoofer's room correction again to compensate.

CARE AND CLEANING OF YOUR POWERED SUBWOOFER

Your subwoofer has a sealed, wood veneer finish that should only require dry dusting or cleaning with a dry cloth. Avoid the use of abrasive or solvent-based cleaners and harsh detergents. The brush attachment of your vacuum should remove any dust from your subwoofer enclosure and grille.
