NA D11GBtrol (section 11 on remote control drawing) to increasethe relative level of mid-frequencies in the sound.Rotate control 18 on the front panel counter clockwiseor the press the MID - button on the remote control(section 11 on remote control drawing) to decrease therelative level of mid-frequencies in the sound.Changing the mid control has a significant effect onvocals, trumpets, violins, etc.5. TREBLE: Rotate control 19 on the front panelclockwise or the press the TREBLE + button on theremote control (section 11 on remote control drawing)to increase the relative level of high-frequencies in thesound. Rotate control 19 on the front panel counterclockwise or the press the TREBLE - button on theremote control (section 11 on remote control drawing)to decrease the relative level of high-frequencies in thesound. Changing the TREBLE setting has a significanteffect on cymbals, hi-hats and other percussion instru-ments.• Infrasonic, Mid & Treble tone controls.This DSP function works and operates in the samemanner to the DSP function described above but BASShas been replaced by a non-adjustable Infrasonic filter.The infrasonic filter removes very low frequencieswhich can sometimes have a disturbing effect on theoverall music quality. These low frequencies, whichoften do not have any relation to the music itself, canemanate from a turntable or recordings made from itand sometimes even CD players. If these extremelylow frequencies aren’t filtered out they can put a signifi-cant strain on power amplifiers and loudloudspeakers.It is relatively easy to check if any of your programmaterial contains unwanted infrasonic sounds:1. Remove the grilles from the loudloudspeakers(check the owner’s manual of the loudloudspeakersfirst for the correct procedure; note that not all loud-loudspeakers have removable grills).2. Select the Infrasonic & Mid & Treble DSP function(16; button Infra & tone on remote control, section 3 onremote control drawing), but do not switch DSP in yet.3. Whilst playing music at a normal, realistic listeninglevel observe the loudspeaker cones.4. Without changing volume, switch DSP in (15; but-ton IN/OUT on front panel, 10 on remote control draw-ing). If there is a significant reduction in loudspeakercone movement then it is likely that that particular pieceof music does contain unwanted low-frequency energy,in which case it is recommended you leave Infrasonicswitched on.• FMOften stereo FM radio reception is hampered by highlevels of background hiss, caused by poor reception orthe radio transmitter being too far away for clear recep-tion. Under such circumstances switch the tuner toMono. The noise will decrease significantly.The FM DSP function allows you to reduce this hisswhilst maintaining a level of stereo or even create asimulated stereo depending on the level chosen.1. Select the FM DSP function (16; button FM onremote control, section 3 on remote control drawing).2. Switch on DSP (15; button IN/OUT on front panel,10 on remote control drawing).3. Rotate the control (17) fully counter clockwise, or ifyou are using the remote control, press BASS Down(section 11 on remote control drawing) until the LEDbar in the display area (26) indicates minimum level, asin the drawing below.4. Turn up control (17) or press the BASS +button onthe remote control until the hiss has been reduced toan acceptable level. What in fact happens is that fromfull stereo (and maximum of hiss) the stereo separationis reduced more(and thus the hiss) as the setting ismoved towards the maximum position. As stereo sepa-ration is reduced the FM DSP function generates spa-ciousness by using stereo simulation. At the maximumposition the source itself is fully mono (no channel sep-aration) but spaciousness and spread has beenregained thanks to the stereo simulation.NOTE: The FM DSP function works on all inputswhich can be useful, e.g. to play back a recording of abroadcast containing a lot of hiss.NOTE: For the Stereo simulation to work properly it isimportant that the perceived volume level from eachspeaker is identical.• WidthMany recordings, although stereo, can still soundrestricted in terms of perceived imaging and sound-stage, or the correct stereo effect cannot be enjoyed tothe full because of physical restrictions in loudspeakerpositioning (too close together).Alternatively, on some recordings -particularly olderones- the Left / Right separation for stereo can be toosevere, making for a very artificial overall sound. Usingthe stereo information available on the recording, theWidth DSP function can make the stereo image wideror narrower.1. Select the Width DSP function (16; button Widthon remote control, section 3 on remote control draw-ing).2. Switch on DSP (15; button IN/OUT on front panel,10 on remote control drawing).3. Start from the neutral setting (original stereosound, no widening or narrowing) at the 12 o’clockposition for the front panel control knob (17). Whenusing the remote control, press the BASS + or - buttons(section 11 on remote control drawing) to adjust to theneutral position, indicated by the LED bar (only thesquare centre LED should light up) in the display panel(26):FMWIDTHBASS INFRASONIC MIDSPREADTREBLECOMPRESSIONFMWIDTHBASS INFRASONIC MIDSPREADTREBLECOMPRESSION
