digital home theatre technology advanced features ypao sound optimisation yamaha s ypao sound optimisation system analyses the room acoustics and various system factors then makes adjustments to provide optimum sound quality in addition to the previous adjustments for speaker size distance and wiring plus equalisation and level advanced ypao gives this useful function even higher performance with four new capabilities the first is measurement at multiple locations for a larger sweet spot at the listening position the second is the use of parametric equalisation to cancel the effects of standing waves the third is speaker angle measurements to optimise cinema dsp effects and the fourth is an easy starter feature technology to create harmonics from the remaining music data utilised by the dsp circuit it focuses on the fact that the music elements that are lost when the original music is digitally compressed are mainly the harmonics it combines high frequency expansion processing which improves the unconstrained treble sound with low frequency emphasis processing which supplements the deep bass sound these processes vividly revive the range presence force and dynamism of compressed music 10 0 heard with maximum clarity the dialogue lift function causes part of the front and centre channel sound to be output from the presence speakers so you hear the dialogue more clearly assignable amplifiers for bi-amp connection bi-amping assigns the amps used for the surround back channels to work in conjunction with the front speaker amps to provide separate high and low frequency outputs to the front speakers this provides more power to the front speakers for multi-channel or hifi sound both high frequency and low frequency sound quality is improved adaptive drc adaptive drc dynamic range control is a new volume control technology that is effective for lowvolume listening such as at night or with headphones it applies drc processing to eliminate the volume differences between loud commercials and ordinary programming and to take into account our ears loss of sensitivity as the volume decreases the compensation is performed automatically so all dialogue is heard clearly even at low levels and there are no sudden loud bursts of sound effect of adaptive drc drc off adaptive drc small sounds like whispers sounds cannot be heard low low input level high output level compressed music compressed music enhancer on compressed music off compressed music enhancer off db -50 -100 0 5 10 15 20 frequencykhz frequency khz we recommend using the compressed music enhancer function when listening to songs with a groove feeling and lively music such as rock soul disco and r&b microphone base dsp-z11 compressed music enhancer mp3 aac and other music formats that use digital compression cut out music data in the high and low frequency ranges and eliminate small sounds during high volume segments in order to decrease the size of the data the fact that data is missing is difficult to hear with portable players but when listening through speakers it is clearly apparent that part of the musical nuance is lost when you listen to this music you will be dissatisfied with the inadequate brilliance of the high range and with the thin response in the mid-low range the compressed music enhancer is an exclusive yamaha function that uses our proprietary dsp on-screen display an on-screen gui graphical user interface display makes operating the component easy and intuitive it is compatible with ipod dsp-z11 gui setup menu internet radio pc and usb displays the display on some components allows six languages to be selected english german french spanish russian and japanese dialogue lift clear dialogue is important for movie enjoyment however when using front and centre speakers positioned below the screen dialogue may not be volume at normal level large sounds can be output so large sounds are output as large sounds high volume at lower level the volume is slightly lowered so the maximum output is smaller high output level volume at considerably lower level when the volume has to be lowered more the maximum output becomes much smaller high low low input level high low low input level high before using dialogue lift ideal dialogue position when drc is off whispered sounds are submerged in the area where sounds cannot be heard when drc is off the area where sounds cannot be heard is fairly large custom installation compatibility yamaha has made it extremely convenient to set up a multiroom custom installation and gives you the ability to do it in a variety of ways now you can have sound in various rooms of the house without the need to purchase a lot of extra components two ways to enjoy sound in your home for multi-room custom installations power amp channels can be assigned in two ways five for the main zone and two for zone 2 for 5.1-channel sound in the main room and three for the main zone and two each for zones 2 and 3 for music in all three rooms without the need for extra amplifiers main zone zone 2 3.1-ch on off second room stereo outüut level zone 3 on off off main room 3.1-channels third room
