The LEHLE TRANSFORMER HZ was specially designed for use with high-impedance signals but also processes lowimpedance signals with uncompromising sound quality. <\/p>\n\n<p>The classic application for the LEHLE P-ISO TRS XLR is as a hum suppressor and for balancing signals. Frequently background noise caused by ground loops occurs when two grounded electronic devices are connected to each other. The LEHLE P-ISO TRS XLR provides a simple, but extremely effective remedy when installed between the two units. By using the isolator, the devices are galvanically isolated and background noise becomes a thing of the past. <\/p>\n\n<p>Thanks to its ability to use it in both directions and the choice of balanced or unbalanced processing, the LEHLE P-ISO TRS XLR is eminently suitable for many signal types and in numerous situations. <\/p>\n\n<p>And just in case you are looking for a power connection: the LEHLE P-ISO TRS XLR performs all its functions without any need for a power supply. <\/p>\n\n<p>And due to its optimised size and low weight, it fits easily below your pedalboard or in any pocket.<\/p>\n<\/div><\/div><div id=\"3694\" 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-p-iso-trs-xlr#3694')\">#<\/span><\/h3><div class=\"entry-content clearfix\"><div id=\"toctoc\"><\/div>\n<figure class=\"wp-block-table\"><table><tbody><tr><td>Weight<\/td><td>206 g<\/td><\/tr><tr><td>Length<\/td><td>71,5 mm<\/td><\/tr><tr><td>Width<\/td><td>47 mm<\/td><\/tr><tr><td>Overall height<\/td><td>34 mm<\/td><\/tr><tr><td>Max.
