Sony ECM-W3 Wireless Microphone

Product Highlights

• Dual-channel wireless microphone for high-quality digital recording The ECM-W3 comprises two microphone-transmitters featuring high signal-to-noise (S/N) ratio microphone units, and a dual-channel receiver. The transmitters and receiver process audio digitally and transmit it wirelessly, allowing the capture and recording of two speakers' voices with superb clarity and low noise.
• High-quality digital sound recording High signal-to-noise ratio (S/N) microphone units are integrated into the two combined microphone-transmitters, enabling clear voice recording with low noise.
• High-quality dual-channel digital transmission Connecting the dual-channel receiver to a camera1 from Sony that supports the Multi Interface (MI) Shoe, such as one of the α™ series digital interchangeable-lens cameras or vlog cameras, allows the digital audio signal output from the receiver to be recorded directly by the camera body, enabling high-quality sound recording with minimal noise contamination.
• Noise-suppressing filter functions A noise-cut filter using digital signal processing to effectively remove noise, and a low-cut filter that reduces noise in the low-frequency range, are provided on the microphone side. Less noise removal is needed post-production, making workflow more efficient.
• USB digital audio output Digital audio (48 kHz/24 bit) can be output from the receiver via USB cable to a smartphone or PC, or to a USB audio input compatible device5 for recording.
