3. 10K SOCKET
Connect your effects pedal or keyboard
with a jack cable to this socket.
The 10K socket controls your effects ped-
al or keyboard that works with expression
pedals within a range of 5kΩ to 20kΩ.
This socket can also be set to a latching
or momentary switch and, e.g. switch the
channel of your amplifier.
The 10K socket has 5 different socket-
modes:
Polarity Autodetection, TRS, RTS,
momentary switch and latching switch.
By pressing the soft button (6) the socket-
mode will be changed:
- Polarity Autodetection:
Both LEDs are white, as long as no
jack is plugged in. Once you connect
a jack to the socket, the LEHLE DUAL
EXPRESSION measures the polarity (RTS,
TRS or TS) and adopts to the polarity au-
tomatically. During the measuring pro-
cess both white LEDs are flashing alter-
nately. After the measuring process only
one LED is on, according to the matching
polarity. The pedal stores the selected
mode, as long as a jack is connected to
the socket.
- TRS
Only the TRS LED is on.
The control voltage is tapped at the tip of
the TRS jack.
- RTS
Only the RTS LED is on.
The control voltage is tapped at the ring
of the TRS jack.
This mode works for TS with a TS jack,
too.
- Momentary switch
The rear LED of the 10K socket flashes
blue. A contact is made between tip and
sleeve, once the rocker reaches a specific
position. If the contact is made, the front
LED is white.
- Latching switch
The rear LED of the 10K socket is con-
sistently blue. A contact is made between
tip and sleeve, once the rocker reaches a
specific position. The contact stays closed
until the rocker reaches the position
again. If the contact is closed, the front
LED is white.
If you use the 10K socket as an expres-
sion controller and not as a switch, it’s
best to try the autodetection first.
Ensure that both LEDs of the 10K socket
are on whilst there is no jack connected.
Now connect the TRS, resp. TS jack to the
10K socket. After the LEDs stop flashing
and only one is on, your effects pedal or
keyboard can receive expression data.
Move the rocker of the LEHLE DUAL
EXPRESSION. If your effects pedal doesn’t
react properly, press the 10K button (6)
to switch from Polarity Autodetection to
10K
