Lehle Stereo Volume Pedal
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.
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.
