{"product_id":"crescendo-duo","title":"SPL Crescendo Duo","description":"\u003cp\u003eCrescendo duo combines the precise sound that German Rundfunk-Technik is famous for with the innovative SPL 120V technology. The internal operating voltage of 120 volts allows Crescendo microphone preamplifiers to break completely new ground. This results in microphone preamps that sound detail-rich, vivid and equally honest.\u003c\/p\u003e\n\u003cp\u003eCrescendo duo lets microphones shine in a whole new light – because they have never been amplified like this before.\u003c\/p\u003e\n\u003cdiv class=\"elementor-element elementor-element-f7f95f0 elementor-widget elementor-widget-heading\" data-id=\"f7f95f0\" data-element_type=\"widget\" data-widget_type=\"heading.default\"\u003e\n\u003cdiv class=\"elementor-widget-container\"\u003e\n\u003ch4 class=\"elementor-heading-title elementor-size-default\"\u003eThe Undistortable\u003c\/h4\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"elementor-element elementor-element-9c2ff40 elementor-widget elementor-widget-text-editor\" data-id=\"9c2ff40\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\"\u003e\n\u003cdiv class=\"elementor-widget-container\"\u003e\n\u003cp\u003eThanks to the SPL 120V technology, it is almost impossible to overdrive this microphone preamplifier.\u003c\/p\u003e\n\u003cp\u003eCrescendo duo is a dual-channel microphone preamplifier with 120V technology.\u003cbr\u003eBoth channels feature the same range of functions. Besides phantom power (48 V) for condenser microphones, polarity reversal, a high-pass filter and a PAD switch, they provide the possibility to adjust the VU meter to display very high levels – so they leave nothing to be desired. The gain can be adjusted comfortably and precisely via a 12-step switch. With the switchable output control, the output level of the Crescendo duo can be perfectly adapted to following AD converters. Two outputs per channel allow the signal to be sent to two different devices in parallel. In addition to the extensive feature set and the outstanding technical characteristics, Crescendo duo convinces with a sonic authenticity that is second to none.\u003c\/p\u003e\n\u003cp\u003e \u003ciframe width=\"560\" height=\"315\" src=\"https:\/\/www.youtube.com\/embed\/EkiN7r7HNqY?si=Z95Wg5OQnAnM5y_M\" title=\"YouTube video player\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"text-decoration: underline;\"\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch4\u003eAnalog input \u0026amp;
