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 Mono Volume 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.
Stereo
Many effects units feature stereo outputs. Or: instruments frequently have two pickup systems, e.g. a combination of conventional magnetic and Piezo types, to emulate an acoustic sound. Lehle accessories are ideal for trouble-free routing of such dual-channel stereo signals. All stereo-capable Lehle products are, of course, also suitable for mono operation.
Balanced Output
Equipped with a standard TRS-socket for balanced output signals if needed.

The Lehle Stereo Volume is a volume pedal equipped with a precise magnetic sensor enabling it to operate almost wear-free. This sensor uses the Hall effect, named after Edwin Hall, to measure the strength of magnetic fields. In the Lehle Stereo Volume, the Hall sensor, which is made in Germany, is accurately calibrated to the built-in magnet and the control range of the pedal. The pedal moves only the magnet, the distance is measured by the Hall sensor which controls a VCA.
A premium Blackmer® Stereo-VCA (= Voltage Controlled Amplifier) from the United States replaces here in this case the mechanical potentiometer. The principle of the voltage-controlled amplifier is based on the fact that gain can be varied by the control voltage coming from the Hall sensor. This technique allows to operate more precisely than conventional mechanical potentiometers or optical sensors used by the standard volume pedals. In addition the potentiometer-typical noise and the complicated adjustment are eliminated.
Over the entire control range the Lehle Stereo Volume transmits the full sound spectrum of the connected instrument. The input and output impedance always stay the same, ensuring that there will be no damping of higher frequencies as with potentiometers.
Internally, the input voltage coming from the power supply socket of the pedal is rectified, then filtered, stabilized and doubled to 18V, thus achieving a total dynamic range of 110 dB.
The volume control of the Lehle Stereo Volume ranges from -92 dB to 0 dB - so from a virtually muted level to the same volume.
The Lehle Stereo Volume runs mechanically extremely smooth and steady, as it is equipped with low-friction bearings of a high-performance polymer, and there is no mechanical transmission of the pedal to other components. By means of an adjusting screw the mobility of the pedal can be modified very precisely.
The Lehle Stereo Volume can both distribute one signal to two outputs and add up two input signals to one output: If only a mono signal is supplied, the signal can be split and sent to two different output channels using the split-function. An input stereo or a dual-mono-signal can be merged to mono via the summing function. The balanced (TRS) as well as unbalanced (TS) outputs make the Lehle Stereo Volume fit for use in studios or FOH-environment, e.g. to control the amount of real-time effects or signal busses.

Q: Can the Lehle Mono Volume also be placed in the amp’s effect loop as a master volume control?
A: Due to the high impedance input and low impedance output it is possible to place the Lehle Mono Volume before the amp or in the amp’s effect loop. The effect loop should be serial or if parallel set to 100% wet.

Q: What is the effect of an impedance converter?
A: The sound will be freshened up and signal loss through long cable runs will be compensated.

Q: How can I compensate the signal loss on my effects board?
A: By using an impedance converter, which provides a high impedance input socket for the instrument signal and a low impedance output signal that is more resistent against loss.

Q: What is the maximum level the Stereo Volume operates with?
A: The Lehle Stereo Volume operates with a maximum level of approx. 3V RMS (approx. +12dBu at 12 V supply voltage). If a keyboard or synthesizer supplies a considerably higher output level, this can create distortions. In this case, reduce the output level of your keyboard or synthesizer.

Expressive
The best thing about Lehle's Volume Pedal was not only the high signal fidelity of the active circuit, but also the extreme accurate and absolute wear-free operation thanks to magnetic-sensor technology.

Quiet pedals!
Burkhard Lehle's high-tech pedals are mechanically, electrically and ergonomically by far the best I've ever got in front of my feet.

The ultimate answer on the subject of volume control.
The handling is self explaining, functionality absolutely convincing. Haptic and feel are brilliant. Simple changes in volume have never before given me so much mischievous pleasure!

Professional volume pedals
Concerning features and functionality both pedals [MONO VOLUME 90 & STEREO VOLUME] are beyond any doubt. Whoever doesn’t want to miss the quality of a professional volume pedal, does not get around the LEHLEs.

Neutral sound in every setting
Sometimes it’s possible to improve already perfect pedals. So happened to the LEHLE STEREO VOLUME and the MONO VOLUME 90.
