Sony ECM-W3S – wireless microphone system

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 ¿ series digital interchangeable-lens cameras or vlog cameras.

A safety function is provided that allows simultaneous recording of two audio signals one at normal volume and the other 20 dB lower reducing the risk of clipping during loud recording.

Microphone audio input/output

A 3.5 mm mini jack (monaural) is provided as an external microphone input terminal on the microphone side and a 3.5 mm mini jack (stereo) on the receiver side serves as an audio output terminal.

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 device for recording.
