TROUBLESHOOTING
PROBLEM
I am experiencing a hum or
high-pitched tone when
recording and listening to my
vinyl on my laptop computer.
The audio from the record
player is too loud and distorted.
CAUSE
Certain models of laptop
computers generate
large amounts of ground
noise. This noise can
leak into your USB audio
device and cause noise
in the audio outputs.
The Phono | Line switch
is set incorrectly.
The Recording Level is
set too high.

SOLUTION
Try an amplifier with an ungrounded plug.
Try an amplifier with a "Ground Lift" switch, and
engage that switch.
Try a "Direct Box" (or "Direct Injection" box) with
ground lift switches between your computer's
audio output and the amp.
Try plugging your laptop into a different power
outlet.
Run the laptop on batteries (not viable for long
periods of time).
Use a 3-to-2 prong adapter for your laptop's power
supply so that the laptop ground is not connected
to the mains outlet. Contact your computer
manufacturer for any safety concerns before doing
this.
Plug your laptop into a power outlet which has a
separate ground (like an Earth ground) from the
other audio devices.
If using a Line-level record player, please ensure
that the Phono | Line switch is set to 'Line' to
prevent the audio from distorting.
Turn down the Recording Level knob.
