LEHLE PARALLEL SW II AS PARALLEL EFFECTS LOOPER IN THE
LOOP OF AN AMPLIFIER
Send
Return
Many amplifiers feature only one serial
effects loop, which means that the signal
is routed entirely via this loop between
the preamp and the power amplifier.
In many cases, the level on the serial ef-
fects loop will be too high for any effects
pedals which you might try to connect
at this point. The LEHLE PARALLEL SW II
enables you to adjust the level for these
effects optimally by turning the Send con-
troller (3) down slightly. Turn the Return
controller (5) up again, to increase the
level back to that of the amplifier's effects
loop.
The signal will often lose warmth, intensity
and depth - everything that makes up the
unique sound of a good tube amplifier! -
when digital effects processors are used

in a serial effects loop. With the LEHLE
PARALLEL SW II, however, you can add
the effect signal to the original sound -
with the pleasing result that you lose none
of your amplifier's excellent sound char-
acteristics and don't have to sacrifice the
effects you love.
HOW TO DO THIS
1. Connect the Send output from the se-
rial effects loop of your amplifier to the
Input socket (1) of the LEHLE PARALLEL
SW II.
2. Connect the Output socket (6) of the
LEHLE PARALLEL SW II to the Return input
of your amplifier's serial effects loop.
3. Connect the Send socket (3) of the
LEHLE PARALLEL SW II to the input of
your effects unit.
