Overview of the Sony ECM-W3 2-Person Wireless Microphone System with Multi Interface Shoe

Use the Sony ECM-W3 2-Person Wireless Microphone System to record interviews and vlogs with two subjects using your Sony Camera that is compatible with Multi Interface. It has two transmitters that clip on and have built-in microphones, and a dual-channel receiver that connects to your camera’s Multi Interface Shoe. The system can record both analog and digital audio signals in either mixed or separate channels, giving you more options for postproduction.

The receiver is very small and has 3.5mm TRS and USB-C output ports. You can use two switches on the side to choose between mixed or separate channel recording and switch between analog and digital output modes. You can also turn on safety track recording to avoid any unexpected interruptions. An attenuator switch on the transmitter units stops clipping.

Bluetooth Wireless Communication

The units communicate with one another via Bluetooth 5.3 low-energy LC3plus codec from up to 492′ away. The Bluetooth LC3plus codec ensures low power consumption and low latency while maintaining high sound quality.

Multi Interface Shoe

Use the receiver’s integrated Multi Interface Shoe for cable-free connection to your compatible Sony camera. The camera body can supply power to the receiver when attached. Audio is transmitted via direct digital signal for high-quality sound free of transmission deterioration.

Digital Sound Recording

Digital MEMS microphones with a high signal to noise ratio are integrated into each transmitter to capture clear audio with low noise. You can eliminate distortion even further using the built-in noise cut and low-cut filters. The noise cut filter uses digital signal processing to remove interference, while the low-cut filter reduces unwanted low-frequency noise such as wind, air conditioning units, and vibrations.

Clip-On Transmitter

• Noise cut filter, low-cut filter
• Three attenuation settings: 0, 10, or 20 dB
• 3.5mm TRS jack for external microphone input

Battery Life

• Each component features an integrated lithium-ion battery.
• The transmitters can operate for six hours at a time on a full charge.
• Use the included charging case to recharge the components when on the go.

Component Design

LED indicators on the receiver and transmitters indicate the communication status and allow you to monitor battery levels. All components are designed to be moisture and dust resistant for outdoor shooting. Included furry windscreens reduce wind noise.
