The ATM250DE dual-element instrument microphone features cardioid condenser and hypercardioid dynamic capsules combined in a single housing. Audio-Technica’s innovative use of two polar patterns is ideal for kick drum: the hypercardioid dynamic element focuses tightly on the aggressive attack of the beater, while the condenser captures the round tonalities of the shell. The elements are positioned in a perfect phase relationship, something practically impossible to achieve with two separate microphones. Includes a professional isolation clamp to provide secure mounting, versatile positioning and effective dampening of unwanted mechanical noise.
Dual element design, a proven specialty of Audio-Technica brings together two elements in a microphone (condenser and dynamic). The dynamic element with rare-earth magnet provides power and attack, while the condenser saves the entire audible range.
The elements of the ATM250DE are positioned in a perfect phase relationship, something practically impossible to achieve with two separate microphones.
The switch is on the condenser element. The high pass filter cuts bass frequencies that attenuate, to limit ringing, handling noise and other noise in frequencies below 80Hz.
