Hi-Sound Stereo EM
Stereo parabolic microphone equipped with 4 EM172 sensor from Primo
36 in stock (can be backordered)
This parabolic microphone can capture sounds with a stereo separation, the signal is routed in a single stereo mini Jack 3.5 mm connector.
The stereo effect is given by the channels separation obtained by placing a separator disc (baffle) between two pairs of microphones, positioned to the left and right channels with two capsules for each channel. The dish is composed by two circuits with top and bottom shield; the same shield is tightly connected to ground of the four capsules so to minimize the immunity to external interferences.
The EM172s are classic very low noise sensor from Primo. Two of them are mounted for each channel (total of 4 capsules).
Having two capsules instead of one allows to obtain a signal gain of approximately +3dB and a lower self inherent noise.
Compared to traditional PZM the greatest improvement in HiSound stereo is done placing the capsule on the same plane with the baffle and not in opposite direction. This configuration can add additional signal gain of +6 dB without having any influence on the high-frequency response.
Hi-sound AOL includes all the components: handle microphone and disc, you only need a compatible recorder.
