Über die MIDI-Schnittstelle können Steuerinformationmen ausgetauscht werden. Alle LEHLE-Produkte mit dem MIDI-Symbol sind vernetzbar mit externem Equipment, um dieses zu steuern und/oder gesteuert zu werden.
VCA とは、電圧制御増幅器です。 これらはオーディオ信号用の小型電子アンプで、電圧を使用してアンプのゲインを制御します。弊社のボリュームペダルは、従来のポテンショメータに代わりこれらのユニットを使用してボリュームを制御しています。これにはいくつかの利点があり、制御範囲全体にわたってはるかに長い寿命と安定した入出力インピーダンスが保たれます。弊社は、THAT コーポレーション製のプレミアム Blackmer® VCA のみを使用しています。
• Analogue signal path – digital control
• High-end preamp with discrete Class-A input stage
• 120 dB dynamic range thanks to 30 V technology
• Magnetic sensor technology, without mechanical wear
• Precise volume control from analogue VCA
• MIDI via USB
• Optimised size and weight
With the LEHLE MONO VOLUME S you get an active and wear-free volume pedal, which is lighter and smaller but not less efficient: Equipped with the proven and evolving magnet sensor VCA technology of the other LEHLE VOLUME pedals, you control the volume of your instrument precisely.
As it has no mechanical potentiometer, the typical noise, endlessly expensive repairs and complicated adjustment can be avoided.
Your foot is just moving the magnet, while the Hall-sensor measures the distance, with great precision and very fast. An ARM Cortex CPU processes the data of the sensor in a matching, musical taper and controls the VCA. Here, the signal path is always kept completely analogue – and in your hands.
Stability – both electronic and mechanical.
Over the entire control range the LEHLE MONO VOLUME S transmits the full sound spectrum of the connected sound source. The input and output impedance always stays the same, ensuring that unlike with potentiometers, there will be no damping of higher frequencies.
The input voltage coming from your power supply (9 – 15 V) is internally rectified, then filtered, stabilized and transformed to 30 V, thus achieving a total dynamic range of 120 dB. The high-end preamp with discrete Class-A input stage brings every little sound nuance to life – your tone becomes touchable.
There are no initial difficulties with the LEHLE MONO VOLUME S: Low-friction bearings of a high-performance polymer bed the shaft gently into the aluminium enclosure and reduce any mechanical stress towards zero – thus, it runs mechanically extremely smooth and steady. By means of an adjusting screw the tension of the pedal can be modified with great precision from feathery to Vintage Car.
In addition to the mains output, a second also buffered direct output is available: Without affecting the sound negatively, you can provide a signal to a tuner, to a DAW or even a second amp.
Zero to hundred or boost à la carte? The LEHLE MONO VOLUME S has a boost available, which can deliver up to +12 dB more gain with a little extra emphasis (push) in the toe position. When and how? By means of using a little button you can recall presets: 0 dB, +5 dB or +10 dB. The preset P4 is the chef’s speciality and remains an audiophile surprise.
The USB-C socket provides the functionality to calibrate, program and update the LEHLE MONO VOLUME S – by the way it sends MIDI data to your DAW or amp simulation of your choice.
Compared to the LEHLE MONO VOLUME we were able to reduce the weight by 50 % and the size by 35 % – with the same rugged stability and yet more dynamic. It’s even 2 cm flatter, however the pedal range stays the same – just as comfortable and responsive as the larger models.
This is the LEHLE MONO VOLUME S: more volume – but half the size.
