The DM7 is a cardioid dynamic microphone, based on the original SM7b. The DM7 produces a vocal presence peak which can enhance the voice. It also has an internal windscreen and does not require a shock mount. It features a switched bass/rumble filter or HP filter and  switched presence rise. The DM7 also works well on horn recording and on instrument amplifiers.
 
 Capsule:
The dynamic capsule has a 150 ohm impedance.
It is mounted in an internal  isolation mount and and has a hum bucking coil.
This reduces EMI noise from cell phones or other studio gear.

WHEN THE PRESENCE SWITCH DISENGAGED THE SM7 ITS 2DB BETWEEN 5KHZ AND 7KHZ.
