RANE SL4 FOR SERATO SCRATCH LIVE • OPERATOR’S MANUAL 2.5.0

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 SL4 is

set to receive a phono level input. Switch

to the correct setting on the SL4.

PHONO INTO LINE INPUT - The SL4 is set

to receive line level input. Switch to the

correct setting on the SL4.

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 SL4 or mixer.

USING PIGGYBACK CABLES - Picking up lots

of noise, barely tracking. Connect your

turntables directly to the SL4.

DAMAGED NEEDLE - Try re-seating, cleaning

or replacing your stylus.
