The Sony ECM-W3S consists of a microphone-transmitter with high signal-to-noise (S/N) ratio microphone units and a single-channel receiver. Audio is processed digitally by the transmitter and receiver and transfers them wirelessly, letting the speaker’s voice be captures with excellent clarity and low noise.
Top-Notch Digital Sound Recording
Thanks to the integrated signal-to-noise ratio microphone units into the microphone-transmitter, voice recording becomes crystal-clear with low noise.
Top-Notch Digital Transmission
If the user connects the 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, they can use the camera to directly record the digital audio signal output from the receiver. This enables high-quality sound recording with very little voice contamination.
Unique Noise-Suppressing Filters
A noise cut filter that uses digital signal processing in order to effectively remove noise, and a low cut filter that reduces low-frequency range noises are added to the side of the ECM-W3S. Workflow becomes smoother as less time is spent removing background noise during post-production.
Compatible with Multi Interface Shoe
The user can connect the receiver to a Sony camera that supports the Multi Interface (MI) Shoe such as one of the α series digital interchangeable-lens cameras or vlog cameras without the need of cables, resulting in immediate sound acquisition and avoiding interference with the vari-angle LCD monitor even if it is horizontally opened while shooting. This results in better mobility and freedom to choose different shooting angles.
The Wireless Benefit
The microphone-transmitter and single-channel receiver helps in the wireless capture of speakers’ voices. With Bluetooth 5.3 (Bluetooth Low Energy) and LC3plus codecs providing low power consumption, low latency, and better sound quality, you can record from a distance of up to 492 feet (150 m) in clear line-of-sight locations. Battery size has also been reduced thanks to the superior power saving features.
Safety and Attenuator Features
With its safety function, the ECM-W3S can simultaneously record two audio signals, one at a normal volume while the other 20 dB lower. This reduces the risk of clipping, common during loud recordings. Additionally, an attenuator function is provided to let the recording level to be set on three values depending on the audio volume.
Microphone Input and Output Support
On the microphone’s side is a 3.5 mm mini jack (monaural) to function as an external microphone input terminal, and on the receiver’s side is a 3.5 mm mini jack (stereo) that functions as an audio output terminal. Sound acquisition can also be done through a stereo-compatible lavalier microphone. Sound output can also be done to devices that are not equipped with a Multi Interface (MI) Shoe.
USB Digital Output from Receiver
The receiver can also transmit digital audio output of 48 kHz per 24 bit using a USB cable to PCs, smartphones, and also to USB audio input compatible devices for recording.
Compact and Lightweight Build
Due to the microphone transmitter’s compact and lightweight design, it provides excellent mobility and portability, making it easy to carry while you’re on the move or while shooting. They are also resistant to dust and moisture, making them ideal for the outdoors.
Get Status Notifications
With the LINK lamp, you can know the status between of communication between the microphone and receiver and avoid recording errors. You can also know the battery status with the POWER lamps on the microphone and receiver.
Get Battery Assistance
The receiver gets direct power supply from the α series digital interchangeable-lens cameras or vlog cameras to the receiver.
Backup Charging Case
The microphone-transmitter is accompanied by a small charging case, letting you continue shooting without getting concerned about diminishing battery power. It can last continuously for approximately six hours on a full charge.
Wind Screen Included
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.
