Sony ECM-W3 Dual-Channel Wireless Microphone for High-Quality Digital Sound Recording

The Sony ECM-W3 Microphone features two microphone transmitters with high signal-to-noise (S/N) ratio microphone units and a dual-channel receiver. The wireless transmission between the transmitters and receiver allows you to capture two speakers’ voices with clarity and minimal noise.
Dual Channel Digital Transmission
When you connect the dual-channel receiver to a Sony camera that supports the Multi-Interface (MI) Shoe, like one of the α series digital interchangeable-lens cameras or vlog cameras, it allows the digital audio signal output from the receiver to be recorded directly by the camera. This enables high-quality sound recording with minimum noise.
MI Compatibility
The fact that the receiver can be easily attached to a camera from Sony helps with immediate sound acquisition. This gives the user the freedom to shoot anywhere and everywhere.
Wireless Convenience
The ECM-W3 has two microphone transmitters and a dual-channel receiver allowing communication at up to 492 ft (150 m) with Bluetooth 5.3 (Bluetooth Low Energy). The LC3plus codecs provide low consumption of power accompanied by high sound quality and low latency. This power-saving feature has immensely helped in reducing the size of the battery.
Safety Functions
The safety function of this model allows simultaneous recording of two audio signals, one of them at a normal volume, the other one at 20Db lower. An attenuator function allows the recording level to be set at one out of three values decided based on audio volume.
Input and Output
The microphone side features a 3.5 mm mini jack (monaural) as an external microphone input terminal. Additionally, a stereo-compatible Lavalier microphone can be used, as well as output to devices that are not equipped with an MI shoe is also possible.
Lightweight and Handy Design for Easy Outdoor Use
Carry them to shoots conveniently as this microphone transmitter and receiver has a perfectly handy and lightweight design. Dust and moisture-resistant, it can be used outdoors.
Status Notifications
It features a LINK lamp that displays the status of the communication channel between the microphone and receiver. This allows for erasing errors. The POWER lamps on both the mic and receiver show the battery levels to help prevent errors occurring from dead batteries.
Battery Assistance
The power supply is transferred directly from the α series digital interchangeable-lens cameras or vlog cameras to the receiver.
Charging Case
The ECM-W3 Microphone comes with a small charging case that lets you shoot continuously without any hassles of power. The microphone-transmitter unit continuously operates for an average of 6 hours when fully charged.
Wind Screen
The windscreen on the microphone reduces wind noise that happens due to breathing or strong wind flow. This included accessory is an essential piece as it allows clear recording of the speaker’s voice, even if the shoot is held outdoors.
