Features and Controls - 4 Back Panel Features

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 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 touch keys 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. From this screen, press the Down or Up touch key to access other control settings.

System Info Press 

This screen is used to access the software “Version” number and “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.

This section describes the features and connections found on the amplifier on the back panel of the subwoofer. It also describes the manner for connecting a second subwoofer as a “slave” unit to the primary subwoofer.

Power On/Off

This is the main AC 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) or when mak-

ing any connections to the subwoofer.

USB

This USB computer interface allows access to additional advanced features within the subwoofer’s ARC 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 connection. Please contact your authorized Klip-

sch dealer or Klipsch Technical Support for more information.

Line Out

There are both RCA-type and XLR connections provided for line out signals. Choose the one appropriate for your system. Do not use both at the same time. This connection can be used as an alternate connection point for a second subwoofer as opposed to connecting them both to your electronics. Be aware that the signal output from these jacks is affected by the “Volume”, “EQ”, “Lowpass”, “Lowpass Slope”, “Phase” and “Room Correction” settings of your Palladium subwoofer. The advantage of this is the ability of the Adaptive Room Correction (ARC) function to correct the response of the second subwoofer resulting in a more accurate response. If the second subwoofer is connected directly to your system, the Palladium subwoofer’s ARC will react to, rather than control, the response of the other subwoofer. As a result, we recommend the following procedure when connecting a second sub- woofer to these outputs:

•Play a signal, such as one of the Palladium subwoofer’s two demo tracks and set the volume control of the second subwoofer to approximately match that of the Palladium subwoofer.

•Defeat the secondary subwoofer’s lowpass setting by selecting the “Bypass” or “LFE” mode or set the lowpass 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 Palladium subwoofer.

•As with the initial setup of your Palladium subwoofer, listen to a track with a repeating bass line in your listen- ing 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 Palladium 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

ARC function, you will have to either reset them to the location they were at when the room correction was performed or run the ARC calibration again to compensate.
