The E321 gooseneck microphones are designed with high quality sound
pick-up performance for professional recording, broadcasting, and
conferences. Suitable for human voices, or music instruments.
Uniform directivities across working frequency band, cardioid and super
cardioid directional capsules provides high gain before feedback in live
sound applications. With omni capsule, this microphone provides excellent
sound pick-up with uniform frequency response regardless of the distance
variation, and it provides very clean speech at up-close pick-up.
Works with standard phantom power supply ranging from 9 to 52VDC, E321
works with almost all kinds of professional audio mixing consoles or
microphone pre-amplifiers.
