Equipped with a trimming resistor, which can adjust the sensitivity and easily change the monitoring distance and range.  \u003cbr\u003e   \u003cbr\u003e   \u003cstrong\u003eScope of application:\u003c\/strong\u003e  \u003cbr\u003e   \u003cbr\u003e It can be used in factories, banks, schools, trains and other production facilities that need to be monitored. It can be used as auxiliary equipment such as monitoring and synchronous recording. It can also be used as a megaphone with the power amplifier. Connecting two modules can be used as an intercom system.  \u003cbr\u003e   \u003cbr\u003e   \u003cstrong\u003eTips:\u003c\/strong\u003e  \u003cbr\u003e   \u003cbr\u003e When the signal is too strong, or the pickup and the speaker are close together, self-excitation may occur. At this time, you can set the amplifier volume.  \u003cbr\u003e Turn down or reduce the sensitivity on the module.  \u003cbr\u003e The positive and negative sides of the interface are marked, pay attention to it when wiring.  \u003cbr\u003e The output needs to be connected to the amplifier to hear the sound, and cannot be directly connected to the speaker. Do not need to connect the amplifier when recording.  \u003cbr\u003e   \u003cbr\u003e   \u003cstrong\u003ePackage included:\u003c\/strong\u003e  \u003cbr\u003e   \u003cbr\u003e 5 x Microphone Pickup Audio Microphone Amplifier Module DIY  \u003cbr\u003e     \u003cbr\u003e    \u003cbr\u003e    \u003cimg src=\"https:\/\/imgaz.staticbg.com\/images\/oaupload\/ser1\/banggood\/images\/5C\/E7\/c47099fc-89d4-4236-95f9-86b25741e218.jpg\"\u003e   \u003cbr\u003e    \u003cbr\u003e    \u003cimg src=\"https:\/\/imgaz.staticbg.com\/images\/oaupload\/ser1\/banggood\/images\/72\/5D\/6b79f594-5c85-46e9-86a8-79eecf354b30.jpg\"\u003e   \u003cbr\u003e    \u003cbr\u003e    \u003cimg src=\"https:\/\/imgaz.staticbg.com\/images\/oaupload\/ser1\/banggood\/images\/FE\/55\/291be305-e0e7-44a5-a22a-a51576a6e41d.jpg\"\u003e   \u003cbr\u003e    \u003cbr\u003e    \u003cimg src=\"https:\/\/imgaz.staticbg.com\/images\/oaupload\/ser1\/banggood\/images\/5C\/AE\/28a74199-a222-4e7c-b409-a910fd12a342.jpg\"\u003e   \u003cbr\u003e    \u003cbr\u003e    \u003cimg src=\"https:\/\/imgaz.staticbg.com\/images\/oaupload\/ser1\/banggood\/images\/EE\/C8\/601785cb-5c2c-48fc-8771-7a53f4198307.jpg\"\u003e   \u003cbr\u003e    \u003cbr\u003e    \u003cimg src=\"https:\/\/imgaz.staticbg.com\/images\/oaupload\/ser1\/banggood\/images\/F7\/16\/0f9cd570-283f-4f41-a1e7-28a9c364879e.jpg\"\u003e   \u003cbr\u003e","brand":"ZHIQIAN","offers":[{"title":"Default Title","offer_id":43928371462339,"sku":"ZHIQIAN-015827","price":406.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0661\/4355\/1683\/files\/6b79f594-5c85-46e9-86a8-79eecf354b30.jpg?v=1725735655","url":"https:\/\/wrsss.com\/products\/5pcs-microphone-pickup-audio-microphone-amplifier-module-diy-kit-dual-track-output-gain-adjustable-d","provider":"Wrsss","version":"1.0","type":"link"}
