By using the soft-touch switches you can switch between two connected amplifiers hum-free and without sound loss.<\/p>\n\n<p class=\"print-content\">Two different operating modes are ready for you.<\/p>\n\n<p>You decide if you want to activate or deactivate every output individually or if you want to switch between the amps and activate the remaining one. <\/p>\n\n<p class=\"print-content\">Both modes can be operated with or without pop suppression.<\/p>\n\n<p class=\"print-content\">The LEHLE-Switches work with a microcontroller and an intelligent True-Bypass- Relay-Circuit with active pop noise suppression circuit.<\/p>\n\n<p>Thereby they switch the LEHLE LITTLE DUAL II even faster than mechanical switches and in addition to that wear- and noise-free.<\/p>\n\n<p>The easy-action mushroom-shaped buttons characteristic of LEHLE products are mounted in the cover, so that your foot pressure is transmitted indirectly only, via a spring. Thus the circuit board is not exposed to mechanical loads, making the LEHLE LITTLE DUAL II virtually indestructible and guaranteeing years of troublefree switching.<\/p>\n\n<p>High-intensity LEDs make it easy to read off switching state A or B, or both, even under high-power spots.<\/p>\n\n<p>The centrepiece of the LEHLE LITTLE DUAL II is its high-end LEHLE TRANSFORMER HZ, which galvanically isolates output A from output B, making history of hum loops &#8211; permanently! The LEHLE LITTLE DUAL II features a gold-plated contact phase inverter and a gold-plated contact ground switch.<\/p>\n\n<p class=\"print-content\">The two inputs can also be routed in stereo to outputs A and B, if you use the stereo signal of an effects unit as the input, for example. This also makes it possible to route instruments equipped with two pickups, including many acoustic and hybrid guitars, and also double basses, via two amplifier systems &#8211; with no complications.<\/p>\n\n<p class=\"print-content\">Additionally the LEHLE LITTLE DUAL II is equipped with a TRS switch. Therewith it is possible to send in above-mentioned stereo- or dual-mono signals via a TRS jack or \u201cstereo-jack\u201d. <\/p>\n\n<p class=\"print-content\">These signals can be operated either in alternation or in parallel &#8211; without hum, and without sound losses, needless to say.<\/p>\n<\/div><\/div><div id=\"3364\" 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-little-dual-ii#3364')\">#<\/span><\/h3><div class=\"entry-content clearfix\"><div id=\"toctoc\"><\/div>\n<figure class=\"wp-block-table\"><table><tbody><tr><td>Weight<\/td><td>540 g<\/td><\/tr><tr><td>Length<\/td><td>3.9\u201c<\/td><\/tr><tr><td>Width<\/td><td>4.8\u201c<\/td><\/tr><tr><td>Overall height<\/td><td>1.85\u201c<\/td><\/tr><tr><td>Supply voltage<\/td><td>9 \u2013 15 V DC<\/td><\/tr><tr><td>Current consumption<\/td><td>63 mA<\/td><\/tr><tr><td>Max.

Chorus and delays create a very wide soundscape when played through 2 amps simultaneously.<\/p>\n\n<p>In case you don\u2018t have enough space for your second amp or it\u2018s simply too loud you can easily sum down the stereo signal to mono. <\/p>\n\n<p>If both input jacks A\/B (2) and A (3) are plugged-in, but not output jack A (6), a passively summed signal will be sent out of output B (4). Please keep in mind that the stereo signal has to be sent out of one device. If the signals are coming from two different devices, an impedance mismatch can occur and the mix won\u2018t sound balanced. In this case, for active summing of two different signals we recommend using the LEHLE PARALLEL SW II.<br\/><\/p>\n\n<h4 class=\"wp-block-heading\">HOW TO DO THIS:<\/h4>\n\n<ol class=\"wp-block-list\">\n<li>For the left stereo signal connect the output socket A (6) to the input of amp 1.<\/li>\n\n\n\n<li>Connect the output socket B (4) to the amp that should render the right FX signal.<\/li>\n\n\n\n<li>Connect the left stereo output from your effects unit to the input socket A (3).<\/li>\n\n\n\n<li>Connect the right stereo output from your effects unit to the input socket A\/B (2).<\/li>\n\n\n\n<li>Activate both amps using the foot switches (10).<\/li>\n\n\n\n<li>Use the phase inverter switch (5) to find out which setting you prefer.<\/li>\n\n\n\n<li>Use the ground lift switch (7) to determine which position eliminates the most background noise.<\/li>\n\n\n\n<li>Done!<\/li>\n<\/ol>\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\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>If your stereo effects unit has only TRS stereo output, use a TRS-TRS stereo cable to make a connection to the LEHLE LITTLE DUAL II.<\/p>\n\n\n\n<p>Use the input socket A\/B (2) only and press the TRS switch (1).<\/p>\n<\/div><\/div><\/div><\/div><\/div>\n<\/div><\/div><div id=\"3479\" class=\"ininebodyinner\"><h3 class=\"inline-pagetitle\">as an amp switcher in a wet\/dry system<span class=\"inlinedoc-postlink inner\" onclick=\"prompt('Press Ctrl + C, then Enter to copy to clipboard','https:\/\/support.lehle.com\/en\/manual\/typical-uses-lehle-little-dual-ii#3479')\">#<\/span><\/h3><div class=\"entry-content clearfix\"><div id=\"toctoc\"><\/div>\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"684\" src=\"https:\/\/support.lehle.com\/wp-content\/uploads\/2024\/07\/wet-dry-system-1024x684.jpg\" alt=\"\" class=\"wp-image-3172\" srcset=\"https:\/\/support.lehle.com\/wp-content\/uploads\/2024\/07\/wet-dry-system-1024x684.jpg 1024w, https:\/\/support.lehle.com\/wp-content\/uploads\/2024\/07\/wet-dry-system-300x200.jpg 300w, https:\/\/support.lehle.com\/wp-content\/uploads\/2024\/07\/wet-dry-system-768x513.jpg 768w, https:\/\/support.lehle.com\/wp-content\/uploads\/2024\/07\/wet-dry-system.jpg 1512w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<h4 class=\"wp-block-heading\">DEVICE CONNECTION<\/h4>\n\n\n\n<figure class=\"wp-block-table tabelleohne is-style-regular\"><table><tbody><tr><td><img decoding=\"async\" class=\"wp-image-3134\" style=\"width: 0px;\" src=\"https:\/\/support.lehle.com\/wp-content\/uploads\/2024\/07\/ab.svg\" alt=\"\"\/><img decoding=\"async\" class=\"wp-image-3134\" style=\"width: 100px;\" src=\"https:\/\/support.lehle.com\/wp-content\/uploads\/2024\/07\/ab.svg\" alt=\"\"\/> <\/td><td>Input <\/td><td>Instrument \/<br\/>dynamic effects<\/td><\/tr><tr><td><img decoding=\"async\" class=\"wp-image-3140\" style=\"white-space: normal; font-family: inherit; width: 100px;\" src=\"https:\/\/support.lehle.com\/wp-content\/uploads\/2024\/07\/b-up.svg\" alt=\"\"\/><\/td><td>Output<\/td><td>Wet effects<\/td><\/tr><tr><td><img decoding=\"async\" class=\"wp-image-3142\" style=\"font-family: inherit; width: 100px;\" src=\"https:\/\/support.lehle.com\/wp-content\/uploads\/2024\/07\/a-up.svg\" alt=\"\"\/><\/td><td>Output<\/td><td>Amplifier 1 (Dry)<\/td><\/tr><\/tbody><\/table><\/figure>\n<\/div>\n<\/div>\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n<p>When setting up two amps and effects, it\u2018s not necessary to use stereo effects only &#8211; mono effects can be used too, in order to get a wider, but more controllable sound picture. There is talk of a wet\/dry system, where one amp gets the dry signal (without effects) and the other amp the wet signal (with effects). By doing this you keep the original dry signal, but you can control the amount of effects on the second amp. We recommend placing dynamic effects (volume pedal, compressor, overdrive\/ distortion) between your instrument and the LEHLE LITTLE DUAL II so both amps benefit from them, while the modulation and time based effects (chorus, tremolo\/ vibrato, delay, reverb) are sent to one amplifier only. Place them between the LEHLE LITTLE DUAL II and the wet amp.<\/p>\n\n<h4 class=\"wp-block-heading\">HOW TO DO THIS:<\/h4>\n\n<ol class=\"wp-block-list\">\n<li>Connect the output socket A (6) to the input of the dry amp.<\/li>\n\n\n\n<li>Connect the output socket B (4) to wet effects and finally the wet amp.<\/li>\n\n\n\n<li>Connect your instrument or the output of the dynamic effects to the input socket A\/B (2)<\/li>\n\n\n\n<li>Activate both amps using the foot switches (10).<\/li>\n\n\n\n<li>Use the phase inverter switch (5) to find out which setting you prefer.<\/li>\n\n\n\n<li>Use the phase inverter switch (5) to find out which setting you prefer.<\/li>\n\n\n\n<li>Use the ground lift switch (7) to determine which position eliminates the most background noise.<\/li>\n\n\n\n<li>Done!<\/li>\n<\/ol>\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\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>To get absolute control of the effect level you can place a volume pedal like the LEHLE MONO VOLUME between the output B (4) and the wet effects.
