Sony ECM-S1 Wireless Streaming Microphone

Sony ECM-S1 Wireless Streaming Microphone

Compact, lightweight wireless streaming microphone
With both wireless and wired connections available, the ECM-S1 portable streaming microphone is a compact and lightweight high-performance unit that provides clear, low-noise, minimum audio delay, high-quality audio for easy recording or live-streaming either indoors or outdoors.

High-quality microphone capsules for clear voice recording
Despite its compactness and light weight, the ECM-S1 is equipped with three large-diameter (14 mm) microphone capsules that provide clear, high-quality sound recording with a flat frequency response, particularly in the low-mid-range voice band, while suppressing noise. Great sound quality makes a huge contribution to the overall impression made on viewers by well-produced video.

Low intrinsic noise levels deliver clear sound
The low intrinsic noise and wide dynamic range of the microphone allow clear capture of even low-level sound. Designed for streaming, the microphone is tuned particularly to capture the rich textures of the human voice near the mouth clearly and naturally.

Directivity selectable to suit the scene
Three directional sound capture modes are provided: Uni-directional, Omni-directional, and Stereo. A switch on the side of the microphone allows the user to select the appropriate directivity for the current scene or usage situation.

Noise-suppressing filter functions
A digital noise cut filter removes persistent background noise, and a low cut filter on the microphone side reduces unwanted low-frequency sound from wind, air conditioning, and vibration. Less noise reduction is needed post-production, improving workflow efficiency.

Pop guard to suppress popping noise
A pop guard is included to prevent the annoying popping sounds that can occur due to vocal plosives when the microphone is placed close to the speaker's mouth, allowing vocals, narration, and other audio to be recorded under optimal conditions.

Compact, lightweight body design
The ECM-S1 comprises compact and lightweight1 microphone / transmitter and receiver units that provide excellent functionality with high digital sound quality. It can be used in a wide variety of environments, both indoors and outdoors with a camera.

Operability for real-time confirmation and adjustment
An independent AUDIO LEVEL dial allows real-time adjustment of the audio input level with the upper dial. In addition, the connection status between the microphone and receiver can be checked with the LINK lamp.

Suitable for long hours of outdoor shooting
The receiver and microphone each have built-in batteries. The receiver can be used continuously with direct power supply when connected to the camera's Multi Interface (MI) Shoe2 or to a PC or other device3. The microphone can be used continuously for about 13 hours when fully charged. The microphone can be used for long periods of time without worrying about the battery.

Improved flexibility in audio recording through wireless transmission
Bluetooth 5.3 (Bluetooth Low Energy) and a LC3plus4 codec provide low power consumption, low latency, and high sound quality. Communication is possible at up to 492 ft (150 m) when there is a good line of sight, for flexibility in outdoor microphone placement.

Supports a variety of mounting and attachment methods
The microphone can be attached to a stand6 during recording, and the angle of the microphone can be adjusted back and forth. Alternatively, the 1/4″ thread on the bottom of the microphone can be used to mount the microphone on a tripod, or a conversion adaptor can be used to attach the microphone to a boom arm.

Multi Interface (MI) Shoe for minimal audio delay and cable-less power supply
Connecting the receiver to a camera8 from Sony that supports the Multi Interface (MI) Shoe, such as one of the α™ series digital interchangeable-lens cameras or vlog cameras, eliminates the need for a separate cable to supply power or to provide the audio interface.

Wireless sound recording in conjunction with a camera
By connecting the receiver to a camera from Sony that supports the Multi Interface (MI) Shoe with a digital audio interface, high-quality audio can be captured and transmitted digitally without degradation, with the wireless connection allowing maximum shooting freedom.
