The LEHLE DUAL EXPRESSION is an active, wear-free expression pedal equipped with a precise magnetic sensor. Known from the LEHLE VOLUME pedals, this sensor uses the Hall effect, named after Edwin Hall, to measure the strength of magnetic fields.  <\/p>\n\n<p>In the LEHLE DUAL EXPRESSION the Hall sensor is accurately calibrated to the built-in magnet and the control range of the pedal \u2013 where the pedal moves only the magnet, whose distance is measured by the Hall sensor. Two digital potentiometers, working with analogue voltages, are used for the precise and reliable generation of the expression data. <\/p>\n\n<p>This technology allows distinctly more accurate operation than is offered by conventional expression pedals with mechanical potentiometers. There is no mechanical wear, avoiding the need for maintenance or complicated adjustments. <\/p>\n\n<p>Both outputs can control nearly all common devices with expression inputs from 5k\u03a9 to 100k\u03a9, regardless if TS, TRS or RTS \u2013 the polarity can be switched and stored using the soft-push buttons.<\/p>\n\n<p>Alternatively, the 10K output can be set to work as a latching or momentary switch, if the pedal is pushed in fully toe position. Then, e.g. the channel of an amp can be changed or, connected to a switch-input of a digital device, any desired function can be controlled. Via the USB socket you can calibrate, edit and update the LEHLE DUAL EXPRESSION via the free online editor LEHLE VERWALTER \u2013 and by the way it sends MIDI data to a computer, in order to control midi compatible software or any hardware device offering a USB host.<\/p>\n\n<p> In use, the LEHLE DUAL EXPRESSION is extremely smooth and steady under foot, as it is equipped with low-friction bearings of a high-performance polymer. By means of an adjusting screw the mobility of the pedal can be modified with great precision. <\/p>\n\n<p>Compared to the LEHLE MONO VOLUME we were able to reduce the weight by 50% and the size by 35% \u2013 with the same rugged stability. It\u2019s even 2 cm flatter, however the pedal range stays the same &#8211; just as comfortable and responsive as the larger models. <\/p>\n\n<p>Light, small, and twice the precise expression: LEHLE DUAL EXPRESSION.<\/p>\n<\/div><\/div><div id=\"3054\" class=\"ininebodyinner\"><h3 class=\"inline-pagetitle\">Technical Data<span class=\"inlinedoc-postlink inner\" onclick=\"prompt('Press Ctrl + C, then Enter to copy to clipboard','https:\/\/support.lehle.com\/en\/manual\/lehle-dual-expression#3054')\">#<\/span><\/h3><div class=\"entry-content clearfix\"><div id=\"toctoc\"><\/div>\n<figure class=\"wp-block-table\"><table><tbody><tr><td>Weight<\/td><td>766 g<\/td><\/tr><tr><td>Length<\/td><td>200 mm<\/td><\/tr><tr><td>Width<\/td><td>90 mm<\/td><\/tr><tr><td>Overall height<\/td><td>47 mm<\/td><\/tr><tr><td>Supply voltage<\/td><td>9 \u2013 15 V DC<\/td><\/tr><tr><td>Current consumption<\/td><td>max. 100 mA <\/td><\/tr><tr><td>Max.

In most cases your effects pedal offers a control \/ potentiometer that cares about the mix amount of your delay pedal. This potentiometer will now be replaced by an external expression pedal, that also usually works with a potentiometer.   <\/p>\n\n<p>The procedures, how this is being done, are as complicated as they are varied. Typically, your effects pedals send a voltage of 3.3 V or 5 V to the potentiometer of the expression pedal. The potentiometer as a variable resistor routes a part of the voltage back. The sent back voltage \u2013 also called control voltage \u2013 is being changed by the position of the potentiometer. The effects pedal measures the control voltage and thus can modify a parameter. In the above-mentioned example the mix amount would be changed.     <\/p>\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n<div class=\"wp-block-getwid-section check alignfull\"><div class=\"wp-block-getwid-section__wrapper\"><div class=\"wp-block-getwid-section__inner-wrapper\"><div class=\"wp-block-getwid-section__background-holder\"><div class=\"wp-block-getwid-section__background\"><\/div><div class=\"wp-block-getwid-section__foreground\"><\/div><\/div><div class=\"wp-block-getwid-section__content\"><div class=\"wp-block-getwid-section__inner-content\">\n<p>Instead of stereo jacks or mono jacks we are talking rightly about TRS and TS jacks.<\/p>\n<\/div><\/div><\/div><\/div><\/div>\n\n<div style=\"height:50px;width:0px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n<p><strong>The individual cables and polarities in summary:<\/strong><\/p>\n\n<p><strong>RTS: <\/strong>the control voltage is being applied to the ring of the TRS jack. <\/p>\n\n<p><strong>TRS: <\/strong>the control voltage is being applied to the tip of the TRS jack.<\/p>\n\n<p><strong>TS: <\/strong>here the effects pedal measure the voltage between sleeve and tip of the TS jack. <\/p>\n<\/div><\/div><div id=\"5242\" class=\"ininebody padding-bottom-45\" ><div class=\"page-title-header\"><h2 class=\"inline-pagetitle\">General Description<span class=\"inlinedoc-postlink\" onclick=\"prompt('Press Ctrl + C, then Enter to copy to clipboard','https:\/\/support.lehle.com\/en\/manual\/download-manual-13#5242')\">#<\/span><\/h2><\/div><div class=\"post-cat margin-btm-35\"><\/div><div class=\"entry-content clearfix\"><div id=\"toctoc\"><\/div>\n<div class=\"wp-block-getwid-image-hotspot\" data-appearance-animation=\"none\" data-image-points=\"[{&quot;link&quot;:&quot;#external-power-supply&quot;,&quot;icon&quot;:&quot;fas fa-circle&quot;,&quot;title&quot;:&quot;4.

BASE AND FIXING<\/h4>\n\n\n\n<p>If needed, you can mount the LEHLE DUAL EXPRESSION to a plate such as a pedalboard.&nbsp;<\/p>\n\n\n\n<p>The LEHLE DUAL EXPRESSION can easily be mounted to a plate using the prepared fixing system of the pedal.&nbsp;<\/p>\n\n\n\n<p>You need 4 screws (4.2&#215;13) and 4 M4 washers.&nbsp;<\/p>\n\n\n\n<p>First, we recommend that you pull out the rubber feet on the bottom.&nbsp;<\/p>\n\n\n\n<p>Place the pedal without the rubber feet in the position where you want to attach it to the board. Use a fine-point pen or a sharp pencil to sketch the subsequent screw holes through the 4 mounting holes onto the base plate. Now drill at the site of the later screw holes a hole with a diameter of approximately 2.5 mm (1\/10 inch).&nbsp;<\/p>\n\n\n\n<p>Then turn in two of the four screws together with the washers just halfway.&nbsp;<\/p>\n\n\n\n<p>Slowly slide the LEHLE DUAL EXPRESSION with the holes under the screw heads of the screws already screwed in. Make sure that the washers are placed between the bottom plate of the LEHLE DUAL EXPRESSION and the screw head to protect the paint.&nbsp;<\/p>\n\n\n\n<p>Now you can turn in the remaining two screws and spacers through the other two mounting holes. Tighten those screws only slightly, then fix the screws you first turned in. This type of mounting is extremely stable and can also be easily removed.&nbsp;<\/p>\n\n\n\n<p>For flexible solutions we recommend using 3M Dual Lock\u2122 instead of velcro for stability.<\/p>\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<div class=\"wp-block-getwid-section check alert\"><div class=\"wp-block-getwid-section__wrapper\"><div class=\"wp-block-getwid-section__inner-wrapper\"><div class=\"wp-block-getwid-section__background-holder\"><div class=\"wp-block-getwid-section__background\"><\/div><div class=\"wp-block-getwid-section__foreground\"><\/div><\/div><div class=\"wp-block-getwid-section__content\"><div class=\"wp-block-getwid-section__inner-content\">\n<p>If you are using the velcro \/ Dual Lock\u2122 method, please make a note of the serial number from the bottom of the pedal before you cover it, in case you have a support question for us later and don\u2018t fancy dismantling your board!<\/p>\n<\/div><\/div><\/div><\/div><\/div>\n<\/div>\n<\/div>\n\n\n\n<p><\/p>\n<\/div><\/div><div id=\"3062\" class=\"ininebody padding-bottom-45\" ><div class=\"page-title-header\"><h2 class=\"inline-pagetitle\">Calibrating the pedal travel and the switching output<span class=\"inlinedoc-postlink\" onclick=\"prompt('Press Ctrl + C, then Enter to copy to clipboard','https:\/\/support.lehle.com\/en\/manual\/download-manual-13#3062')\">#<\/span><\/h2><\/div><div class=\"post-cat margin-btm-35\"><\/div><div class=\"entry-content clearfix\"><div id=\"toctoc\"><\/div>\n<p>In factory setting the pedal range of the LEHLE DUAL EXPRESSION is perfectly calibrated and the switch output of the 10K socket is being triggered in the last few millimetres.<\/p>\n\n\n\n<p>However, you can easily adjust the pedal to your needs using the <a href=\"https:\/\/verwalter.lehle.com\" data-type=\"link\" data-id=\"https:\/\/verwalter.lehle.com\" target=\"_blank\" rel=\"noreferrer noopener\">LEHLE VERWALTER<\/a>, our free online editor.<\/p>\n\n\n\n<div class=\"wp-block-getwid-section check\"><div class=\"wp-block-getwid-section__wrapper\"><div class=\"wp-block-getwid-section__inner-wrapper\"><div class=\"wp-block-getwid-section__background-holder\"><div class=\"wp-block-getwid-section__background\"><\/div><div class=\"wp-block-getwid-section__foreground\"><\/div><\/div><div class=\"wp-block-getwid-section__content\"><div class=\"wp-block-getwid-section__inner-content\">\n<p>Normally, it doesn\u2019t need a calibration again.<\/p>\n<\/div><\/div><\/div><\/div><\/div>\n\n\n\n<h4 class=\"wp-block-heading\">1.

The LEHLE DUAL EXPRESSION offers the possibility to send MIDI data via the USB socket to control software on your computer. E.g. you can control effects or volume in your digital amplifier simulation or manipulate the filter of your synthesizer in your DAW.
