Lehle P-Split II Operating Instructions Manual page 10

1. Input socket
 Connect your instrument or the output from an
effect unit or DAW here.
The input signal is fed into this socket. The Lehle
P-Split II operates entirely passively. The input
signal remains connected to the ISO and DIR
outputs at all times, with no semiconductors or any
other active components in the signal path.
Both balanced and unbalanced signals can be
split, since the Lehle LTHZ transformer is capable
of handling both types.
2. Output socket for direct signal
 Connect the input of an amplifier or effect unit
to be connected directly to the Lehle P-Split II
input here.
The input signal and its ground are present
directly on the DIR socket. The signal from the DIR
output is always the same which is fed into the
input (1). If the input signal is unbalanced you will
have an unbalanced direct signal at this socket.
The same will occur with balanced signals.
3. Phase inverter switch
 The phase of the input signal from the ISO
8
output can be inverted if necessary.
This switch can be used to invert the phase of the
input signal from the ISO socket by 180°. Splitting
signals to two amps may sometimes cause phase
cancellations, resulting, for most musicians, in a
"thin" sound. Inverting the phase eliminates this
problem. Experiment to find out which position
you prefer - as always, your individual taste is
what counts!
4. Ground lift switch
 Connect the grounds of the DIR and ISO output
if necessary.
Pressing this switch connects the ground conduc-
tors of the ISO and DIR outputs.
Connecting the ground conductors of the DIR
and ISO outputs can help in some situations,
depending on the units connected and on their
power supplies. Actuate the ground lift switch to
find out for yourself the position in which noise is
minimised.
5. ISO output
 Connect your amp or the audio input of a DAW
or a mixer here.
