A wide variety of sound recording methods

Multi Interface (MI) Shoe compatible

The receiver can be easily attached to a camera0 from Sony that supports the Multi Interface (MI) Shoe, such as one of the α™ series digital interchangeable-lens cameras or vlog cameras without cables, allowing immediate sound acquisition and avoiding interference with the vari-angle LCD monitor even when it is opened horizontally for shooting. This allows a greater degree of freedom and mobility when shooting.

The convenience of wireless

The ECM-W3S comprises a microphone-transmitter and a single-channel receiver, allowing wireless sound capture of one speaker’s voice. Communication is possible at up to 150 m in clear line-of-sight locations, with Bluetooth 5.3 (Bluetooth Low Energy) and LC3plus codecs providing low power consumption, low latency, and high sound quality. Power saving has also enabled a reduction in battery size.

Safety and attenuator functions

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. An attenuator function is also provided, allowing the recording level to be set to one of three values according to the audio volume.

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. In addition to sound acquisition using a stereo-compatible lavalier microphone, output to devices not equipped with a Multi Interface (MI) Shoe is also possible.
