HOW TO CALiBRATe SCRATCH LiveWith music playing in the background, put yourneedle on the record with the turntable stopped.If you are using CD players, the same rulesapply. Have the CD deck paused or stoppedwhile calibrating.Click and hold the estimate button until the sliderstops moving. Moving the threshold slider to theleft will make Scratch Live more sensitive to slowrecord movement, but also more sensitive tobackground noise.Repeat the process for each deckThings to remember:• Your needle must be on the record.• Your turntable (or CD player) must bestationary.• The background music playing must be at asimilar level to which you will play your set at.• You should calibrate Scratch Live every timeyou play.TiP: if the slider jumps to the far right,then you have a problem with noise in yourturntables/CD players/mixer. Check all yourconnections and make sure your equipmentis well earthed. in some situations you willnot be able to improve the signal quality, andyou will have to play on regardless. in thissituation, stick to rel mode.the ScOpeSThe scopes on the setup screen in Scratch Livedisplay the input signal as a phase diagram. Thekey factors to look at on the scope display arecrisp clean lines, round shape, and the trackingpercentage in the lower right corner.Start both turntables or CD players. You willsee green rings appear in the scope view, asshown above.CALiBRATinGScRatch LIveSince Scratch Live is controlled by an analoguesignal, there is no guarantee of what state thatsignal will be in by the time the software gets tointerpret it. Therefore, Scratch Live needs to beable to handle a wide range of signals, and beconfigurable to use them optimally. Calibratingis just configuring the software to your situation.Calibration is equally important for both vinyland CD users of Scratch Live.There are two parts to the Scratch Live controlsignal: The directional tone, and the noise map.Listening to the control vinyl, the directional toneis the 1 kHz tone. The noise map sounds likerandom noise over the top of the tone.The directional tone provides the currentspeed and direction of the record, while thenoise map tells the software precisely where onthe record the needle is currently.the nOISe thReShOLdA threshold is a lower limit, below which aprocess will not occur. In the case of ScratchLive, the noise threshold is the limit below whichthe input signal will not be interpreted as controlsignal; in other words if it’s below the threshold,it is considered noise and ignored.This setting is necessary because a stylus isvery sensitive, and will inevitably pick up noisefrom the environment as well as the signal on therecord, especially in the noisy environment of alive show.pLayIng ReguLaR vInyL and cdSnOTe: the SL 3 must be powered by USB orthe supplied external power supply for theDeCk THRUs to work.While Scratch Live is not running, and theSL 3 is powered by the external supply, the deckthrus on the SL 3 will always be on, allowingyou to play regular CDs and vinyl with your CDplayers or turntables.When the SL 3 is powered by the universalpower supply, and then Scratch Live is launched,the deck thrus are still on. This allows a laptop tobe connected during a set (when using the deckthrus) with no audio interruption.If the SL 3 is not powered by the universalpower supply when Scratch Live is launched(USB connected), the deck thrus will be off, butcan be turned on in Scratch Live.To turn the thrus off and on in Scratch Live,click on the thru button for the respectivechannel in Scratch Live. This will change thestate of the channels to thru mode, sendingaudio direct from the SL 3 inputs to your mixer.See “THRU BUTTOnS” On PAGe 13.pOWeR SuppLyConnect the barrel connector of the powersupply to the 7.5 VDC jack on the SL 3. Plugthe power supply into an AC outlet. The yellowPOWER indicator will light on the SL 3.The universal power supply includes differentinput plugs for the USA, Europe, UK andAustralia. The USA plug is attached at the factory— you may need to replace it in your country.To remove a plug,PUSH the buttonwhile turning the outerrim counterclockwise.To attach a plug,rotate it to fit intothe supply and turnclockwise until it locksin place.The power supply is regulated 7.5 volts DC, 1amp, using a P6 type barrel plug. Any substitutemust meet these specifications.-(5.5mm) +(2.5mm)LOCKLOCKPUSHOPENOPENRANE SL 3 FOR SERATO SCRATCH LIVE • OPERATOR’S MANUAL 1.98
