CHAPTER 5
Using the TGIV
Bass Management
Unlike higher frequencies, it is diffi cult to discern exactly from which direction lower bass is coming from.
The TGIV has a bass management system which takes advantage of this effect. It allows you to choose whether your speakers will play the full fre- quency 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 informa- tion 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 manage- ment system (so set all the speakers to Large). Without a subwoofer, you will be missing the 5.1 LFE (low fre- quency 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
Video Conversion
The TGIV has advanced digital video DSP circuitry and coding which allows the following:
•Up conversion from composite video inputs to
•Up conversion from
•Down conversion from
The video conversion makes the TGIV able to switch all of your video sources, making it the central con- troller for all of your audio and video entertainment.
For example, suppose you have
your TV connected to the component video outputs of the TGIV. Any of your other video sources can be connected to the TGIV, even those which do not have component video. The TGIV will convert any composite and
Notes:
•Do not connect both compos- ite and
•The quality of the converted output is limited by the quality of the original source.
•The Tuner, Tape and Phono in- puts do not have video inputs. When these are selected, the video stays on the last selected video source.
