Shure SM89
Shotgun Condenser Microphone
The Model SM89 is a highly directional “shotgun” condenser microphone designed for broadcast and video work.
On axis, the SM89 produces a presence peak for speech intelligibility. The mic’s frequency response below 3000Hz is nearly identical up to 30° off axis; Shure explains the benefit of this feature:

The SM89 can be used for pickup at greater angles off-axis than is possible with other shotgun microphones. This feature permits deliberately locating the desired source up to ±30° off-axis in order to ensure that an undesired source is entirely off-axis and will not be picked up. Changes in frequency response above 1,000 Hz can then be compensated by simple equalization if necessary.
The mic’s amplifier circuit contains a hardwired high-pass filter (-15dB @ 60Hz) to reduce rumble; the filter’s effective frequency can be changed to 160Hz via a recessed switch on the mic body.
It ships with a carrying case and foam windscreen. A shockmount (Shure p/n A89SM) is available separately, as is a a mic clip (p/n A57F) for mounting on a conventional mic stand.
