Sony ECM-W3S Single-Channel Wireless Microphone for High-Quality Digital Sound Recording

The Sony ECM-W3 Wireless Microphone comprises a microphone-transmitter featuring high signal-to-noise (S/N) ratio microphone units, and a single-channel receiver. The transmitter and receiver process audio digitally and transmit it wirelessly, allowing the capture and recording of one 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 microphone-transmitter, enabling clear voice recording with low noise.

Digital Transmission

Connecting the 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, 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.
