The ECM-W3 includes 2 microphone-transmitters equipped with a high signal-to-noise ratio (S/N) microphone unit and a 2-channel receiver.
The audio is digitally processed and transmitted wirelessly, so the voices of 2 speakers are captured and recorded with exceptional clarity and reduced noise.

° High quality digital audio recording
High signal-to-noise ratio (S/N) microphone units are integrated into the 2 combined microphone-transmitters, allowing for clear voice recording with low noise.

° High-quality two-channel digital transmission
By connecting the 2-channel receiver to 1 Sony camera that supports Multi Interface (MI) Shoe, such as a™ series interchangeable lens digital cameras or vlog cameras, the digital audio signal output from the receiver can be recorded directly from the body of the camera, for high-quality audio with minimal noise.

The microphone includes a noise-cancelling filter with digital signal processing and a low-pass filter that reduces low-frequency noise.
Less noise removal is required in post-production for greater efficiency.

° Compatible with Multi Interface Shoe
You can easily attach the receiver to a Sony camera that supports Multi Interface (MI) Shoe, such as a™ series interchangeable lens digital cameras or vlog cameras, without cables, allowing immediate sound capture and avoiding interference with the Vari-angle LCD monitor even when opened horizontally, for greater freedom and mobility when shooting.

A 3.5mm mini-jack (monaural) is provided as the input terminal for the external microphone on the microphone side, while a 3.5mm mini-jack (stereo) on the receiver side serves as the terminal for the audio output.
In addition to audio capture via a compatible stereo lavalier microphone, you can also use the output to devices not equipped with the Multi Interface (MI) Shoe.
