Before you embark on your next video production project, consider the ECM-W3 Dual-Channel Wireless Microphone System from Sony, a trusted name in audio and video equipment. This innovative system is designed to deliver high-quality, digital sound recording with two microphone-transmitters, each featuring a high signal-to-noise (S/N) ratio microphone unit. The ECM-W3 system processes audio digitally and transmits it wirelessly, ensuring the capture and recording of two speakers' voices with remarkable clarity and minimal noise. This dual-channel digital transmission is ideal for use with Sony cameras that support the Multi Interface (MI) Shoe, such as the a series digital interchangeable-lens cameras or vlog cameras. This compatibility allows the digital audio signal output from the receiver to be recorded directly by the camera, ensuring high-quality sound recording with minimal noise contamination.The ECM-W3 system also features noise-suppressing filter functions. A noise cut filter uses digital signal processing to effectively remove noise, while a low cut filter reduces noise in the low-frequency range. These features mean less noise removal is needed in post-production, streamlining your workflow.The receiver can be easily attached to a compatible Sony camera without cables, allowing immediate sound acquisition and avoiding interference with the vari-angle LCD monitor. This wireless design offers a greater degree of freedom and mobility when shooting. Communication is possible at up to 492ft (150 m) in clear line-of-sight locations, with Bluetooth 5.3 (Bluetooth Low Energy) and LC3plus codecs ensuring low power consumption, low latency, and high sound quality.Safety and attenuator functions are included to reduce the risk of clipping during loud recording. A 3.5 mm mini jack is provided as an external microphone input terminal on the microphone side, and a 3.5 mm mini jack on the receiver side serves as an audio output terminal. Digital audio can also be output from the receiver via USB cable to a smartphone or PC, or to a USB audio input compatible device for recording.The ECM-W3 system is compact and lightweight, offering excellent mobility and portability. It's designed to be dust- and moisture-resistant, making it a reliable choice for outdoor use. A small charging case is included, allowing continuous shooting without worrying about running out of battery power. The microphone-transmitter unit can operate continuously for approximately 6 hours on a full charge.The ECM-W3 system also includes a wind screen to reduce wind noise, ensuring stable and clear recording of the speaker's voice, even when shooting outdoors. With a wider selection of microphones available from Sony, you can now choose from a broader range of options depending on the situation and application in which you wish to use the microphone.
