The receiver can be easily attached to a camera 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 ECM-W3 comprises two microphone-transmitters and a dual-channel receiver, allowing wireless sound capture of two speakers' voices. 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.
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.
With a wider selection of microphones available from Sony, you can now choose from a broader range of options depending on the situation and application you wish to use the microphone for.
