The E323, E324 compact size, flush mount boundary microphones are
designed for flat surface mounting. Such as tables, walls, or ceiling.
Suitable for professional recording, video conference, television
productions…etc. applications.
The E323 is a half cardioids, uni-directional microphone for live sound
applications, or for reducing un-wanted environment noise.
The E324 is omni directional microphone that picks up all sound.
These microphones incorporating RF shielding, and low
impedance,
balanced output that works with standard 9~52VDC phantom power.
Sturdy metal and double layer mesh grill allows the microphones to be used
in challenging situations.
Pair with vibration reduction rubber that reducing the structure bound
interference.
Finished with none gloss paintings, black or white.
