[. . . ] Although the amplifier's connections and controls are simple, their use varies somewhat according to the subwoofer system's application. Typical setup procedures are described in the following sections ­ one for digital systems and one for analog systems. dIGITAL SURROUND RECEIVER OR PROCESSOR CONNECTIONS Today's Dolby Digital® and DTS® digital surround receivers and processors , as well as all THX-certified models , have line-level subwoofer outputs and built-in subwoofer crossovers. If your system is built around one of these, it will almost always be best to use the RSA-500's LFE input. Use a shielded, high quality subwoofer interconnect cable of appropriate length with RCA plugs on each end. Be sure to go into your receiver or processor's speaker setup menu and set Subwoofer to "On" or "Yes" in the subwoofer menu. Your receiver or processor may have additional bass management abilities beyond simply activating the subwoofer output. Consult your receiver or processor's owner's manual or your dealer for more information on the proper bass management settings for your system. Crossover Adjustment ­ When the RSA-500's LFE input is used, the crossover control will not function. Level Control ­ Play a variety of music recordings containing strong but not overpowering bass. Adjust the RSA-500 level control until the music sounds consistently warm and natural. If you have trouble getting enough low bass without the sound becoming boomy, it probably means the Crossover control is set too high. If the sound is thin until you turn the subwoofer Level up so much that lower bass is too prominent, start by changing the setting of the Phase control. If that does not entirely solve the problem, you probably need to raise the Crossover frequency. ⷠPhase Control ­ In some installations the setting of the Phase control may not make much difference, whereas in others it may be necessary to go back and forth between the Phase and Level controls for a while in order to get the very best blend with the main speakers. Since each control setting (including the one for crossover frequency in the receiver or processor) affects the optimum settings for the others, it often takes a while to get everything dialed in just right. Start with the Phase control at 0° and play a recording with a prominent, repeating bass line in your listening position. General Comments About Adjustments: Since any change in the setting of one control tends to change the optimum settings for the others to some degree, the adjustment process is very interactive and involves a great deal of trial and error. If after a period of listening and calibration you are still not happy, it may mean that you need to experiment a little with the location of the subwoofer. Others have left- and right-channel line-level outputs, as do some stereo receivers and integrated amplifiers. all separate stereo preamps and surround processors have line-level outputs. If your system is built around one of these, it will almost always be best to use the RSA-500's stereo line level inputs.
