The ATM450 cardioid condenser offers an innovative side-address design for endless placement options and minimal obstructions. The microphone is equipped with an integral 80 Hz hi-pass filter that provides easy switching from a flat frequency response to a low-end roll-off. The ATM450 also features a switchable 10 dB pad that lowers the microphone's sensitivity, providing higher SPL capability for flexible use with a wide range of performers and system configurations. The microphone’s extended flat frequency response makes it ideal for high SPLs as well as for live and amplified acoustic instruments. Includes a professional isolation clamp to provide secure mounting, versatile positioning and effective dampening of unwanted noise.
