Lehle Mono Volume 90 Pedal

The description of this item has been automatically translated. If you have any questions, please feel free to contact us.




The Lehle Mono Volume 90 is a wear-free volume pedal that is equipped with a very precise magnetic sensor. This sensor uses the Hall effect, named after Edwin Hall, to measure the strength of magnetic fields. With the Lehle Mono Volume 90, the German-made Hall sensor is precisely calibrated to the built-in magnets and the control path of the pedal. The pedal only moves the magnet; its distance is measured by the Hall sensor, which then controls a VCA.

The high-quality Blackmer® VCA (= Voltage Controlled Amplifier) ​​from the USA replaces the mechanical potentiometer here. The principle of voltage-controlled amplifiers is based on the fact that the gain is varied by the control voltage coming from the Hall sensor. This process enables significantly more precise work than the usual mechanical potentiometers or optical sensors of common volume pedals, and the noise typical of potentiometers or the complicated adjustment are eliminated. The Lehle Mono Volume 90 transmits the full sound spectrum of the connected instrument over the entire control path. The input and output impedance always remains the same, so there is no treble attenuation like with a potentiometer. Internally, the input voltage of the pedal behind the power supply socket is rectified, filtered, stabilized and then doubled to 18 volts. This makes it very level-stable and achieves a total dynamic range of 110 dB.

The volume control of the Lehle Mono Volume 90 goes from -92 dB to 0 dB - i.e. from practically silent to equally loud. The minimum volume of the Mono Volume 90 can be adjusted using the MIN control; It regulates a range from mute (0%) to -10dB (approx. 90%) of the original level. In addition, the gain control can be used to achieve a gain of approx. +12 dB can be set.

Mechanically, the Lehle Mono Volume 90 runs extremely smoothly and evenly because it is equipped with low-friction bearings made of a high-performance polymer and there is no mechanical transmission of the pedal to other components. The movement of the pedal can be adjusted very precisely using an adjusting screw.

In addition, the Lehle Mono Volume 90 has a buffered direct out. Everything from the tuner, DAW to the second amp can be supplied here without affecting the sound.
