Scope Reading and Fixes Most of the problems that occur with Scratch Live can be attributed to it not getting a good reading of the control signal from your records or CDs. These examples show what the scopes on the setup screen can look like to help solve possible problems. Some problems cause similar looking scopes, e.g., if your scopes look like the Dusty Needle one, the cause could be a damaged needle. GOOD SIGNAL - Clean signal with 100% tracking. NO SIGNAL - Scratch Live is not receiving any control signal - check your connections. BAD TURNTABLE VIBRATION - Bass is reaching the stylus. Try to isolate the turntable from the speakers. CD PLAYER INTO PHONO INPUT - The SL3 is set to receive a phono level input. Switch to the correct setting on the SL3. PHONO INTO LINE INPUT - The SL3 is set to receive line level input. Switch to the correct setting on the SL3. DUSTY NEEDLE - Dust is preventing the stylus from tracking the groove correctly. Clean your needle and the control vinyl. UNEARTHED - Very susceptible to interference. Attach the turntable's ground wire to the SL3 or mixer. USING PIGGYBACK CABLES - Picking up lots of noise, barely tracking. Connect your turntables directly to the SL3. DAMAGED NEEDLE - Try re-seating, cleaning or replacing your stylus. 38 RANE SL3 FOR SERATO SCRATCH LIVE • OPERATOR'S MANUAL 2.5.0
