Sony ECM-W3S
Single-channel wireless microphone for high-quality digital recording
The ECM-W3S comprises a microphone-transmitter featuring high signal-to-noise (S/N) ratio microphone units, and a single-channel receiver. The transmitter and receiver process audio digitally and transmit it wirelessly, allowing the capture and recording of one speaker's voice with superb clarity and low noise.
Features
High-quality digital sound recording
High signal-to-noise ratio (S/N) microphone units are integrated into the microphone-transmitter, enabling clear voice recording with low noise.
High-quality digital transmission
Connecting the receiver to a camera from Sony that supports the Multi Interface (MI) Shoe, such as one of the ?? series digital interchangeable-lens cameras or vlog cameras, allows the digital audio signal output from the receiver to be recorded directly by the camera body, enabling high-quality sound recording with minimal noise contamination.
Noise-suppressing filter functions
A noise cut filter using digital signal processing effectively removes annoying persistent background noise, for clear recording. A low cut filter on the microphone side also reduces unwanted low-frequency sound from wind, air conditioning, and vibration. Less noise removal is needed post-production, making workflow more efficient.
Multi Interface (MI) Shoe compatible
The receiver can be easily attached to a camera1 from Sony that supports the Multi Interface (MI) Shoe, such as one of the ? series digital interchangeable-lens cameras or vlog cameras, without the need for cables, and be immediately ready for digital sound acquisition without fuss.
The convenience of wireless
The ECM-W3S comprises a microphone-transmitter and a receiver, allowing wireless sound capture of one speaker?s voice. 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.
Safety and attenuator functions
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.
Microphone audio input/output
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. In addition to sound acquisition using a stereo-compatible lavalier microphone, output to devices not equipped with a Multi Interface (MI) Shoe is also possible.
Receiver stand and adaptor with screw hole
A connector protector/stand is included. This can be used both as a stand for the receiver and as an adaptor to attach the receiver to a smartphone clamp, for example.
USB digital audio output
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 device for recording. When using a USB audio input compatible device, set the receiver's slide switch to ANALOG or DIGITAL.
Compact, lightweight body design
The combined microphone-transmitter is of dimensions 25.0 x 52.5 x 20.5 mm and weighs just 17 g. The receiver measures 32.0 x 29.0 x 50.0 mm and weighs just 25 g. Both the microphone-transmitter 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-resistant6, they can be used outdoors without worry.
Battery Assist function
Power is supplied directly from the ?? series digital interchangeable-lens cameras or vlog cameras to the receiver.
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.
Status notification functions
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.
Compact charging case
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 hours on a full charge.
A wider choice of microphones
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.
