5. RETURN SOCKET
Connect the output of your effects unit
or the output of your second device (e.g.
mixer, computer, second pickup on a gui-
tar, etc.) to this socket.
If you’re using the LEHLE PARALLEL SW
II for parallel effects loops, connect the
output of your effects unit to the Return
socket.
The Return socket can also be used as an
input for other signal sources - the output
from a computer sound card, for exam-
ple, or from a signal processor.
If the LEHLE PARALLEL SW II is being used
to mix two pickups from one instrument,
the Return socket can also be used as the
input for the second pickup.
The Return socket has a 2 MOhm input
impedance. This means that even very
weak signals, such as those generated by
piezo and magnetic pickups can be trans-
mitted without loss of sound.
The Return input’s sensitivity can be ad-
justed using the controller (11).
Like every other socket, the return input
can be used in stereo as well.
Please refer to paragraph “2. Mono-to-
stereo switch“ on page 8.
6. OUTPUT SOCKET
Connect your amplifier or the Return in-
put from the serial effects loop of your
amplifier to this socket.
The device connected here will mostly be
an amplifier, but can also be a mixer, a
stage box or a sound card.
The signal mixed from the input and the
return signal is available here.
The mixing ratio can be controlled using
the MIX controller (10).
Connect the output socket to the Return
input of your amplifier if you want to use
the LEHLE PARALLEL SW II to inject an
external effect into your amplifier’s serial
effects loop.
7. EXTERNAL POWER SUPPLY
Connect a power supply with a voltage
of 9 – 15 V.
In order for the LEHLE PARALLEL SW II
to work flawlessly, it needs a current sup-
ply. This should supply a minimum of 9 V
and a maximum of 15 V. Polarity is of no
importance.
The supply voltage is internally rectified
and stabilized in order to guarantee trou-
ble-free operation.
In order to avoid noise it‘s recommend-
able to use a single power supply or an
output of a multi power supply offering
galvanically isolated outputs for the LEH-
LE PARALLEL SW II.
