Sony ECM-W3S wireless transmitter microphone

The Sony ECM-W3S wireless transmitter microphone includes a microphone-transmitter unit with high signal-to-noise ratio and a single-channel receiver. The transmitter and receiver process audio digitally and transmit it wirelessly, for crisp voice capture and recording with reduced noise. High signal-to-noise (S/N) ratio microphone units are integrated into the microphone-transmitter for crisp voice recording with reduced noise. Connecting the one-channel receiver to a Sony camera that supports Multi Interface Shoe, such as α-series interchangeable lens digital cameras or vlog cameras, allows the digital audio signal output from the receiver to be recorded directly from the camera body, for quality sound recording with minimal noise. The microphone includes a noise elimination filter with digital signal processing and a low-pass filter that reduces noise at low frequencies. Less noise removal is required in post-production for greater efficiency. A safety function allows simultaneous recording of two audio signals, one at normal volume and the other 20 dB lower, reducing the risk of interruptions during loud recording. An attenuator function allows the recording level to be set to one of three available values based on the volume of the audio.
