THX SETUP
There are a number of options that you can set that will be default options when THX mode is selected. Press the OK button on the remote or the front- panel Stage Manager knob to enter the THX Setup menu.
Boundary-Gain Compensation
If the Subwoofer is set to Ultra2 in the Speaker Configuration menu, indicating that your subwoofer is THX Ultra2-certified or capable of reproducing frequen- cies down to 20Hz, the Boundary-Gain Compensation menu will be available. When such a subwoofer is placed close to one or more room boundaries, such as the floor and a wall, very deep bass can be exaggerated by boundary reinforcement. Setting the Boundary Gain Compensation to On applies a filter that will compensate for excessive bass resulting from boundary gain. Press OK on the remote control or the front-panel Stage Manager knob to enter the Boundary Gain Compensation Menu.
Press the Left or Right button on the remote or turn the front-panel Stage Manager knob to adjust to the appropriate setting. Press the OK button on the remote control or the front-panel Enter button or Stage Manager knob to exit the menu.
Advanced Speaker Array
This menu will be available only if you have indicated the presence of sur- round back speakers in the Speaker Configuration menu. You use the Advanced Speaker Array menu to set the distance between the surround back speakers. Options are LESS THAN 12", 12" TO 48", and GREATER THAN 48". You must set this distance correctly to ensure proper operation of the Ultra2 Cinema and MusicMode post-processing modes. The default setting is LESS THAN 12". Press OK on the remote control or the front-panel Stage Manager knob to enter the Advanced Speaker Array menu.
Press the Left or Right button on the remote or turn the front-panel Stage Manager knob to select the appropriate setting. Press the OK button on the remote control or the front-panel Enter button or Stage Manager knob to exit the menu. See also the ASA description in the THX portion of the Mode sec- tion of this manual.
Surround EX Mode
This menu will be available only if you have indicated the presence of sur- round back speakers in the Speaker Configuration menu. The Surround EX
Mode menu enables you to select the operating mode for THX Surround EX processing. Available options are Auto, On, and Off. In the Auto mode, THX Surround EX processing will engage when your system contains both sur- round and surround back speakers, the surround channels in the soundtrack are stereo, and the Dolby Digital bitstream contains a flag indicating that the soundtrack is Surround EX-encoded. The On mode differs only in that it forces THX Surround EX processing even when the bitstream does not con- tain the Surround EX flag. The Off mode turns THX Surround EX processing off. The default setting for the THX Surround EX mode is Auto. Press OK on the remote control or the front-panel Stage Manager knob to enter the Surround EX Mode menu.
Press the Left or Right button on the remote or turn the front-panel Stage Manager knob to adjust to the appropriate setting. Press the OK button on the remote control or the front-panel Enter button or Stage Manager knob to exit the menu.
ASA Mode
This menu will be available only if the system is set up in the Speaker Configuration menu to utilize Surround Back speakers. It enables you to select the operating mode for the Advanced Speaker Array post-processing. Available options for the Advanced Speaker Array mode are Ultra2 Cinema, THX MusicMode, and Off. Ultra2 Cinema mode is most appropriate for movie soundtracks that are not Surround EX-encoded, while MusicMode is better for multi-channel music sources. The default setting is Ultra2 Cinema. Press OK on the remote control or the front-panel Stage Manager knob to enter the ASA Mode menu.
Press the Left or Right button on the remote or turn the front-panel Stage Manager knob to adjust to the appropriate setting. Press the OK button on the remote control or the front-panel Enter button or Stage Manager knob to exit the menu. See also the ASA description in the THX portion of the Mode sec- tion of this manual.
Re-Equalization
The Re-Equalization circuit adjusts frequency response to make movie soundtracks mixed for a theater environment sound correctly balanced in the smaller space of a typical home theater. The default setting for the Re- Equalization circuit is ON. Re-Equalization can be turned off for source material that would not benefit from such processing. If Re-Equalization is turned to OFF, the next time the unit is powered on, it will return to the default ON setting. Press OK on the remote control or the front-panel Stage Manager knob to enter the Re-Equalization Menu.
Press the Left or Right button on the remote or turn the front-panel Stage Manager knob to adjust to the appropriate setting. Press the OK button on the remote control or the front-panel Enter button or Stage Manager knob to exit the menu.
