The SM4 incorporates advanced RF interference shielding technology, protecting your recordings from unwanted noise generated by wireless devices such as smartphones or Wi-Fi routers. This feature is crucial for maintaining the quality of your recordings, even in noisy or congested environments.
Uniform cardioid polar pattern
The SM4's cardioid polar pattern ensures excellent rejection of off-axis noise, minimizing unwanted sound picked up by the microphone. This feature is particularly useful when recording in environments where acoustic control is limited, as it allows you to concentrate on the main sound source.
