NOTES:

•In the Subwoofer Mode screen, you have the flexibility to choose how bass information is distributed to your speakers if you have large front left and right speakers and a subwoofer as part of your home theater speaker system.

•By selecting the “LFE + Main” option, you will be sending the same bass frequencies to both the front left, front right, AND the subwoofer speakers simultaneously. Depending upon your room size and shape, this can create a more evenly distributed bass around the room or sometimes actually decrease the amount of bass in the room due to low frequency cancellations.

•If the “LFE -THX-” option is selected, bass from the large front left and front right speakers goes ONLY to the front left and front right speakers. Bass going to the subwoofer comes from the LFE signal and any speakers which you have designated as “Small.” This selection is preferred by THX as it reduces the chances of bass cancellations in the room.

•Once you have positioned all of your speakers in the room, choose the option which gives you the most solid sounding bass.

ON .............The surround back speakers are always used during playback.

Set the “ON” mode to perform 6.1-channel playback with conventional 5.1-channel sources or sources on which the identification signal described below is not recorded.

AUTO.........This function only works with software on which a special identification signal is recorded. This software is scheduled to go on

sale in the future.

This is a function for automatically playing in the 6.1-channel mode using the surround back speakers if the software is recorded in THX Surround EX or DTS (ES) or in the normal 5.1-channel mode without using the surround back speakers when the software is not recorded in THX Surround EX or DTS (ES).

NOTES:

•The “THX Surround EX” setting screen is displayed when the surround back speaker is set to “Small” at “Speaker Configuration”.

•The surround back speakers can also be turned on and off using the “THX Surround EX” or “6.1/7.1 Surround” surround parameter. (See pages 49, 51 and 56)

Select the setting according to the program source to be played.
