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.
