LEHLE DUAL EXPRESSION WITH AN EFFECTS PEDAL AND AN
AMPLIFIER
The 10K socket can be used as a mo-
mentary or latching switch. This way you
can control external devices.
Channels of amplifiers are usually
switched by a footswitch. How about
doing this with your LEHLE DUAL
EXPRESSION and simultaneously control-
ling an effects pedal?
How to do this as a momentary switch:
1. At the LEHLE DUAL EXPRESSION the
LEDs of RTS and TRS should be both on.
This way the Polarity Autodetection is
active.
In order to use the switching function
of the 10K socket, its function must be
activated.
Hit the 10K button (6), until the LED flash-
es blue, so the LEHLE DUAL EXPRESSION
provides the momentary switch function
when the rocker is in toe position.
2. Connect the 50K socket to the expres-
sion pedal input socket of your multi ef-
fects pedal.
3. After the LEDs of RTS and TRS now
have started and stopped flashing, the
LEHLE DUAL EXPRESSION has selected
the correct polarity automatically.
4. Connect the 10K socket to the foot-
switch input of your amplifier.
5. Move the rocker of the LEHLE DUAL
EXPRESSION. In the position the LEHLE
DUAL EXPRESSION triggers the relay
(usually in the toe position), the channel
of your amplifier is being switched.
6. There you go!
