Bass Management

The TGR-401 has a bass man- agement system that allows you to choose whether your speakers will play the full frequency range, or if the bass will be redirected to the subwoofer.

The advantages of redirecting the bass to a subwoofer are :

•The overall bass of the system is improved as subwoofers, such as Sun re's powered True Subwoofers, are specially designed for this frequency range.

•The subwoofer can simulta- neously play the bass from all of the speakers, in addition to its own low frequency effects channel (LFE).

•There is no loss in percep- tion of the position of movie or music sound effects, as the ear cannot easily locate the posi- tion of bass sound sources.

•Smaller speakers can be used for front, center and sur- rounds, as they do not have to reproduce the low frequency range. This leads to a saving in speaker expense and room space. Note that a subwoofer is required if the front speakers are not set to LARGE.

•The TGR-401 ampli ers do not waste power reproducing the low frequency range.

The SPEAKER SIZE menu is used to set the bass management correctly for your speaker system.

SPEAKER SIZE		CHOICES
FRONT	90HZ	LARGE,40,45,50,55,60,65,...150
CENTER	90HZ	OFF, LARGE,40,45,50,55,60,65,...150
SURROUND	90HZ	OFF, LARGE,40,45,50,55,60,65,...150
BACK SURR	90HZ	OFF, LARGE,40,45,50,55,60,65,...150
NUM BACK	2	N/A,1,2
SPKRS
SUBWOOFER	90HZ	OFF, 40,45,50,55,60,65,...150
SUBWOOFER	NORM	NORMAL, ENHANCED
MODE

The speaker choices are:

OFF: The speakers are not present.

LARGE: the speakers receive the full frequency range, and their bass is not redirected to the subwoofer.

40, 45, 50...150 Hz: The bass below this frequency is redirected to the subwoofer. Check your speaker manuals to nd their frequency re- sponse, and choose a frequency that is above the lowest, or choose 90 Hz as a good starting point.

NOTE: Dolby Digital and DTS modes are designed especially for complete systems with front, cen- ter, and surround speakers and subwoofers. You need all of the speakers to get the best performance from your Home Theater. If you do not have a subwoofer connected and you are using large speakers, then you should not use the bass management system (so set all the speakers to Large). Without a subwoofer, you will be missing the 5.1 LFE (low frequency effects) information.

Considering the advantages of the bass management system, you might try setting all of your speakers to 90 Hz (for example), even if they are capable of good low-frequency performance.

Video Conversion

The TGR-401 has advanced digital video DSP circuitry and coding which allows the following:

•Up conversion from composite video inputs to S-video and component video outputs.

•Up conversion from S-video inputs to component video outputs.

•Down conversion from S-video inputs to the MON composite video output jack.

The video conversion makes the TGR-401 able to switch all of your video sources, making it the central controller for all of your audio and video entertainment.

For example, suppose you have

your TV connected to the component video outputs of the TGR-401. Any of your other video sources can be con- nected to the TGR-401, even those which do not have component video. The TGR-401 will convert any com- posite and S-video sources to compo- nent video.

Notes:

•Do not connect both compos- ite and S-video inputs on the same TGR-401 input. Always connect the highest quality video source type.

•The quality of the converted output is limited by the quality of the original source.

•The TGR-401 has sophisticat- ed video circuitry that requires it to be pre-con gured for only one type of television broad- cast standard. For US models, this is NTSC and for export models, this is PAL-BGIH.

•There is no video conversion for Zone 2, so you must be playing a composite video source to see it in Zone 2.
