The ECM-B6027AML38-728 is an omnidirectional electret condenser microphone designed for integration into portable voice recorders. It captures clear and natural speech with low background noise, making it suitable for voice-focused applications in compact recorder assemblies. Learn more about this microphone on our voice recorder electret microphone page. Why This Microphone Excels for Voice Recorder Assemblies Portable voice recorder assemblies need microphones that deliver intelligible speech even in dynamic or moderately noisy environments. The ECM-B6027AML38-728 achieves this with an omnidirectional pickup pattern, moderate sensitivity, and low self-noise, and is specifically designed for integration into compact recorder circuits and similar audio capture devices. Moderate sensitivity ensures clear output without distortion, while the compact construction […]<\/p>\n","protected":false},"author":1,"featured_media":3359,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[400],"tags":[537,520,518,547],"class_list":["post-3357","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-product-guides","tag-far-field","tag-high-snr","tag-high-spl","tag-o6-0mm"],"_links":{"self":[{"href":"https:\/\/ecmicrophones.com\/ja\/wp-json\/wp\/v2\/posts\/3357","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ecmicrophones.com\/ja\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/ecmicrophones.com\/ja\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/ecmicrophones.com\/ja\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/ecmicrophones.com\/ja\/wp-json\/wp\/v2\/comments?post=3357"}],"version-history":[{"count":0,"href":"https:\/\/ecmicrophones.com\/ja\/wp-json\/wp\/v2\/posts\/3357\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/ecmicrophones.com\/ja\/wp-json\/wp\/v2\/media\/3359"}],"wp:attachment":[{"href":"https:\/\/ecmicrophones.com\/ja\/wp-json\/wp\/v2\/media?parent=3357"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ecmicrophones.com\/ja\/wp-json\/wp\/v2\/categories?post=3357"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ecmicrophones.com\/ja\/wp-json\/wp\/v2\/tags?post=3357"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
