[. . . ] The function of Bass Management is to redirect these low frequencies, when necessary, to speakers that are better designed to handle them, such as the subwoofer. Within this document, LFE refers to the . 1 channel provided by a Dolby Digital soundtrack. Subwoofer will refer to the subwoofer output as a whole, whether it contains just the LFE channel or a downmix of information from other speakers as well. We understand that not all speakers are capable of reproducing a full range signal, however we also understand that most speakers that will be present in a high end system will be capable of handling a full range signal without any detrimental effects. [. . . ] While in the desired mode, press the Test button, and then press the B. Modes button to access the adjustments. Select the desired speaker by pressing the corresponding button in the speaker selection grid in the middle of the remote. (See Above) For each of the five main speakers you will have the choice of No Crossover, or With Crossover. Selecting No Crossover sends a full range signal to that set of speakers. Selecting With Crossover sends the signal for that channel through a high pass filter, of which the crossover frequency is selectable. For example, if you change the Left Front speaker to With Crossover, when you access the Right Front speaker it will already be set to With Crossover. Different subwoofer settings will have different effects on the overall Bass Management settings, especially in Dolby Digital. A subwoofer setting of NO, in Dolby Digital, requires that the LFE channel be distributed to the Large speakers in the system. When the LFE channel is rerouted to another channel in the system, the channel it is rerouted to requires attenuation according to Dolby standards. This is done to accommodate for the worst case scenario in which you have a 0dB Full Scale signal in both the LFE channel, as well as the channel the signal is rerouted to. If the system were to avoid attenuating the channel, an overload would occur in the DSP chip which could result in the damage of your amplifiers and/or loudspeakers. It is important that you understand how the KSP-S6 must accommodate for the LFE channel in Dolby Digital to get the most from your system. The Dolby Digital Bass Management system has an extra option regarding the LFE channel. You can designate the subwoofer output in Dolby Digital to reproduce just the LFE channel, or to reproduce the LFE channel, as well as operate as a true subwoofer, reproducing the low frequencies of every channel. The choice will depend on the type of speakers that you have, and their ability to properly generate low frequency signals. Insert a Dolby Digital DVD into the DVD player, and select that input to allow the KSP-S6 to autoselect Dolby Digital. Press the test button to access the "test setup" and then press the B. Modes button to access the Bass Management setup. In the Speaker Selection Grid, choose the subwoofer, and set it accordingly, YES, or NO. Pressing the Subwoofer button again will allow you to choose whether you want the subwoofer to be LFE only, or LFE + Downmix which gives you a true subwoofer. This setting only applies to Dolby Digital, and does not effect the Bass Management in any other mode. *Note: Due to LFE constraints, when making changes to the LFE mode for Dolby Digital, these changes may not take effect right away, but will take effect the next time Dolby Digital is loaded. Power up the KSP-S6, and be sure the display indicates that you are in Stereo mode. [. . . ] We suggest you use the crossover built into your subwoofer whenever possible. Quick Setup Guide: Dolby Digital (Pro-Logic) 11. 1. Power up your DVD player, and insert a Dolby Digital disc.
