Product Description
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 speakers' voices with superb clarity and low noise.
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 camera¹ from Sony that supports the Multi Interface (MI) Shoe, such as one of the α™ 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.
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.
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 α™ 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.
The convenience of wireless
The ECM-W3S comprises one microphone-transmitter and a single-channel receiver, allowing wireless sound capture of one speakers' voices. Communication is possible at up to 492 ft (150 m)² in clear line-of-sight locations, with Bluetooth 5.3 (Bluetooth Low Energy)9 and LC3plus³ 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.
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 device⁴ for recording.
Compact, and lightweight design
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, they can be used outdoors without worry.⁵
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.
Battery Assist function
Power is supplied directly from the α™ series digital interchangeable-lens cameras or vlog cameras to the receiver⁶.
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 6 hours on a full charge.8
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.
Expansion of Sony's microphone lineup
With a wider selection of Sony microphones available, you can now choose from a broader range of options depending on the situation and application in which you wish to use the microphone.
1 Some models that support the Multi Interface (MI) Shoe, such as the RX1R II and ZV-1, do not provide power via the MI Shoe.
2 Approximate distance when the microphone is visible from the receiver. This varies depending on the surroundings and radio wave conditions, such as the presence of metal, people, or other obstacles or reflective surfaces.
3 LC3plus is the supported audio format in ECM-W3S.
4 Available only when connected to a USB Audio Class 1.0 compatible device. Even if the device is USB Audio Class 1.0 compliant, a separate conversion adaptor may be required for connection depending on the device.
5 Not guaranteed to be 100% dust and moisture proof. Performance may vary depending on the body to which the unit is attached.
6 Power may not be supplied depending on the camera used. Please check the following website for compatible models. https://www.sony.net/dics/ecmw3/
