High signal-to-noise ratio (S/N) microphone units are integrated into the two combined microphone-transmitters, enabling clear voice recording with low noise.

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

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.

The receiver can be easily attached to a camera 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.

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.
