Single-channel wireless microphone for high-quality digital recording

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 unit, 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.

Digital sound recording with superb quality

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 sound recording

Connecting the single-channel receiver to a camera 1 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, enabling high-quality sound recording with minimal noise contamination.

High-quality digital transmission

Noise-suppressing filter functions 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.

Noise-suppressing filter functions

Multi Interface (MI) Shoe compatible The receiver can be easily attached to a camera 1 from Sony that supports the Multi Interface (MI) Shoe, such as one of the ™ series digital interchangeable-lens cameras or vlog cameras, without cables, allowing immediate sound acquisition and avoiding interference with the vari-angle LCD monitor even when it is opened horizontally for shooting. This allows a greater degree of freedom and mobility when shooting.

A wide variety of sound recording methods

The ECM-W3S comprises a microphone-transmitter and a single-channel receiver, allowing wireless sound capture of one speaker's voice. Communication is possible at up to 492 ft (150 m) 5 in clear line-of-sight locations, with Bluetooth 5.3 (Bluetooth Low Energy) and LC3plus 3 codecs providing low power consumption, low latency, and high sound quality. Power saving has also enabled a reduction in battery size.

Multi Interface (MI) Shoe compatible

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.

The convenience of wireless

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.

Safety and attenuator functions

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 4 for recording.

Microphone audio input/output

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-resistant 5 , they can be used outdoors without worry.

USB digital audio output

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.

Compactness, light weight and high reliability

Power is supplied directly from the ™ series digital interchangeable-lens cameras or vlog cameras to the receiver 6 .

Compact and lightweight design

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.

Status notification functions

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.

Battery Assist function

Expansion of Sony's microphone lineup 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 in which you wish to use the microphone.

Extended warranties are usually very inexpensive and can save you thousands in the future. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Electronics can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new electronics should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.
