6. Ground lift switch
 Connect the grounds of output sockets A and B if
necessary.
This switch connects the chassis of outputs A and
B when it is pressed, connecting the ground con-
ductors of the A and B 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.
7. External power supply
 Connect a power pack for a voltage of 8 to 20
V to this socket when needed.
The Lehle Little Dual switches all audio signals
completely without electricity. To detect the switch-
ing status it requires an 8 to 20 V power supply for
operation of the LEDs. Polarity is of no importance.
The supply voltage is internally rectified and stabi-
lized in order to guarantee trouble-free operation.
A thermal cut-out automatically trips and switches
the unit off if a short circuit occurs.
A correctly fitting plug connector for the power
supply socket is supplied with the Lehle Little
Dual and can be soldered to the required power
unit if necessary. It is advisable to use a separate
power adapter or an outlet on a multiple outlet
power adapter with electrically isolated outlets for
the Lehle Little Dual, but with no other loads
connected to it, to avoid interference noise during
operation or when switching.
8. LEDs for switching status
 If the left (A) LED shows green, the output A
(5) is active, if the right (B) LED is red, a signal is
routed thru output B (3).
The high-intensity LEDs under the lenses clearly
indicate switching State A or B, even under stage
lighting.
Output A (left) is GREEN and output B (right) is RED.
9. True-Bypass switch
 Here you can switch.
Two parallel slide switches with gold-plated con-
tacts, which switch the stereo signal together with
the ground connections, are actuated inside the
switcher by means of a practically indestructible
switching mechanism. The slide switches switch
virtually silently, since they function completely
bounce-free.
