Bass Management

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

The Ultimate Receiver 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 SunÞre'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 set to SMALL.

•The Receiver's power am- pliÞers do not waste power reproducing the low frequency range.

See the previous page for informa- tion regarding the adjustment of the bass management crossover points.

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 low-frequency performance.

The Ultimate Receiver has ad- vanced digital video DSP circuitry and coding which allows the following:

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

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

•Down conversion from S-video in- puts to the MON2 composite video output jack.

The video conversion makes the Ultimate Receiver 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 Ultimate Receiv- er. Any of your other video sources can be connected to the Ultimate Receiver, even those which do not have component video. The Ultimate Receiver will convert any composite and S-video sources to component video.

Notes:

•Do not connect both composite and S-video inputs on the same Ultimate Receiver input. Always connect the highest quality video source type.

•The quality of the converted output is limited by the quality of the origi- nal source.

•The Tuner, Tape and Phono inputs do not have video inputs. When these are selected, the video stays on the last selected video source.

•The Ultimate Receiver has sophis- ticated video circuitry that requires it to be pre-conÞgured for only one type of television broadcast standard. For US models, this is NTSC and for export models, this is PAL-BGIH.
