The Sony ECM-B1M is an ultra-compact camera-mount digital shotgun microphone designed for mobile video creators working with Sony cameras equipped with the Multi Interface Shoe. Released alongside the a7R IV, which benefits from its built-in Digital Audio Interface, the ECM-B1M is able to produce its best quality by delivering a digital audio stream directly to the camera through the Multi Interface Shoe. Other Sony cameras with the standard Multi Interface Shoe can still make use of the microphone as there is a selectable digital/analog output. The ECM-B1M is equipped with eight high-performance mic capsules and advanced digital signal processing, providing three selectable directivity patterns for a wide range of shooting and recording situations. Plug-and-play operation makes the microphone easy to use right out of the box—you can immediately start recording your YouTube videos, Facebook Live streams, and interviews, at home, in the studio, or on the go. Compatibility Digital Audio Sony Alpha a7R IV Analog Audio Sony cameras equipped with Multi Interface Shoe Three Directivity Modes Advanced digital signal processing makes it possible to offer three switchable directivity patterns: supercardioid, cardioid, and omnidirectional. Super Directivity in a Compact Mic The microphone is equipped with eight high-performance microphone units that, combined with a beam-forming algorithm, deliver exceptional sharp directivity while effectively eliminating off-axis sound. Despite its powerful capabilities, this compact microphone measures just 3.91" in length. Digital Sound with Low Noise When you use the Multi Interface shoe with a compatible camera that has a built-in digital audio interface, the audio signal is transferred directly to the camera in digital form, ensuring no degradation. Additionally, a simple switch allows compatibility with a broad range of cameras using an analog interface. Effective Controls for Clear Sound The microphone offers record level control, analog output to work with a variety of cameras, and an attenuator for easily setting the optimal signal levels, adding to its versatility. Additionally, it utilizes digital signal processing to implement a low-cut filter that reduces subsonic noise, ultimately enhancing audio quality during recording and minimizing the need for complex post processing later on. Mechanical Noise Suppression The innovative design of this microphone effectively reduces low-frequency and handling noise, ensuring high audio quality. Additionally, the absence of connecting cables prevents any mechanical transmission of noise to the microphone through cables and connectors. A fur windscreen is supplied to help reduce wind noise when shooting outdoors. Cable-Free Connection Introducing the simple solution of clipping the microphone into the Multi Interface Shoe on a compatible camera for direct power and audio connections. Say goodbye to the hassle of extra cables or batteries. Sony's Multi Interface Shoe takes it up a notch by providing intelligent connectivity and control for various accessories, giving you maximum flexibility and mobility. function selectTab(tabName) { document.getElementById('Overview').style.display = “none”; document.getElementById('Specs').style.display = “none”; document.getElementById(tabName).style.display = “block”; switch (tabName) { case “Overview”: document.getElementById(“btnOverview”).className = “active” document.getElementById(“btnSpecs”).className = “button” break; case “Specs”: document.getElementById(“btnSpecs”).className = “active” document.getElementById(“btnOverview”).className = “button” break; } } document.getElementById(“btnOverview”).click();
