Lehle P-Split Ii As A Line Isolator - The Universal Cure For Hum Loops - Lehle P-Split II Operating Instructions Manual

your sound, since balanced inputs are usually low
impedance.
The Lehle P-Split II functions excellently as a
neutral splitter and as a high-quality DI box with
instruments which have active pickups, and/or
when another buffer, such as the Lehle Sunday
Driver is positioned between the instrument and
the input of the Lehle P-Split II.
The Lehle P-Split II as a line isolator – the
universal cure for hum loops
The Lehle P-Split II can be used in any scenario
to eliminate noise resulting from ground loops or
hum. Ground loops occur when units grounded
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
LTHZ transformer included in the Lehle P-Split
II electrically isolates the ground connection. The
hum loop is thus broken at this point. Both high-
and low-impedance signals can be fed, the
12
Lehle P-Split II has no problems with balanced
or unbalanced signals.
