TYPICAL USES
LEHLE P-SPLIT STEREO AS ISOLATOR IN A STEREO SETUP
The LEHLE P-SPLIT STEREO can be used
in any scenario to eliminate noise result-
ing from ground loops or hum.
Ground loops occur when units ground-
ed by a protective earth conductor (“PE
conductor”) are connected to each other.
The protective earth conductor and the
ground connection of the audio signal
create a loop which will pick up external
interference generated, for example, by
coils. Such interference will impair the
signal. The LEHLE TRANSFORMER HZ
galvanically isolate the ground connec-
tion. The hum loop is thus broken at this
point.
Both high- and low-impedance signals
can be fed, the LEHLE P-SPLIT STEREO
has no problems with balanced or unbal-
anced signals.
HOW TO DO THIS
1. Connect the signal source (e.g. an
eects device or amp simulation) to the
input sockets (1) of the LEHLE P-SPLIT
STEREO.
2. Connect the output sockets R ISO and
L ISO (5) to the inputs of your mixer.
3. Use the ground lift switch (4) to deter-
mine which position eliminates the most
background noise.
4. There you go!

DEVICE CONNECTION
If you are using one section of the LEHLE
P-SPLIT STEREO only, use the left one.
Using the right section and toggling the
phase button, will cause the signal to
be muted if the left phase button isn’t
toggled, too.
