LEHLE DUAL EXPRESSION
Gold-plated Relays
The signal from the pickups of an electric guitar or bass is so weak that poor-quality cables, cold joints and cheap contact materials ruin your sound. Switch contacts need to be made of special materials to permit loss-free switching of these low-level signals. All Lehle switchers feature special relays and slide switches with gold-plated contacts for totally reliable, absolutely zero-loss switching.

Voltage Internally Doubled to 18V
To exploit the dynamics of tube amplifiers to the full, the input voltage of Lehle products bearing this symbol is rectified from the power supply socket, then filtered, stabilized and doubled to 18V.Magnetic Sensor
Potentiometers, which are usually installed in volume pedals, are always exposed to extreme wear and tear, so they deteriorate quickly.
In
order to keep the mechanical stress and thus the wear of the pedal as
low as possible, a magnetic sensor, which uses the "Hall
effect“, is installed in the LEHLE VOLUME and EXPRESSION pedals
instead of a potentiometer.
In accelerators of modern cars this has long been standard: a magnet is moved, and a stationary Hall sensor measures very precisely the distance. The magnetic sensor is therefore not exposed to mechanical wear, making these solutions work very reliably.MIDI interface via USB
By means of the MIDI interface, control information can be exchanged. All LEHLE products with the MIDI symbol are able to be networked with external equipment, in order to control it and/or be controlled.USB port
LEHLE products with an USB socket can be connected to a computer by means of this port. Updates, current supply and data transfer make a flexible integration in digital systems possible.
