CHAPTER 5

Using the TGIII

Bass Management

Unlike higher frequencies, it is diffi cult to discern exactly from which direction lower bass is coming from.

The TGIII has a bass management system which takes advantage of this effect. It 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 Sunfi 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 it’s 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 set to Small.

•Your amplifi ers do not waste power reproducing the low frequency range.

See the previous page for information regarding the adjustment of the bass management crossover point.

The SPEAKER SIZE menu is used to set the bass management correctly for your speaker system. See page 38.

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, 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 Small, even if they are capable of good low-frequency performance.
