Sony ECM-W3 Dual-channel Wireless Omnidirectional Microphone

High signal-to-noise ratio (S/N) microphone units are integrated into the two combined microphone-transmitters, enabling clear voice recording with low noise.

Connecting the dual-channel receiver to a camera1KEY_TAB from Sony that supports the Multi Interface (MI) Shoe, such as one of the α series digital interchangeable-lens cameras or vlog cameras.

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.

The receiver can be easily attached to a cameraKEY_TAB from Sony that supports the Multi Interface (MI) Shoe, such as one of the α series digital interchangeable-lens cameras or vlog cameras.

The ECM-W3 comprises two microphone-transmitters and a dual-channel receiver, allowing wireless sound capture of two speakers' voices.

A safety functionKEY_TAB 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.

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.

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 deviceKEY_TAB for recording.

Both the microphone-transmitters and receiver have excellent mobility and portability and are compact and lightweight enough not to get in the way when carrying or shooting. Designed to be dust- and moisture-resistant, they can be used outdoors without worry.

The LINK lamp indicates the status of the communication channel between the microphone and receiver to prevent recording errors. The POWER lamps on both the microphone and receiver indicate battery level to prevent recording errors due to dead batteries.

Power is supplied directly from the α series digital interchangeable-lens cameras or vlog cameras to the receiver.

A small charging case is included in the package, allowing you to continue shooting without worrying about running out of battery power. The microphone-transmitter unit can operate continuously for approximately 6 hours on a full charge.

The included wind screen can be used to reduce the wind noise that may occur when the microphone is impacted by strong wind or breath. This allows stable and clear recording of the speaker's voice, even when shooting outdoors.

With a wider selection of Sony microphones available, you can now choose from a broader range of options depending on the situation and application in which you wish to use the microphone.
