The AMT P800 Studio is a professional trumpet microphone system that combines the P800 trumpet microphone with the AP40 amplifier. The P800 microphone features an extension arm and mount that enables the microphone element to mount directly in front of the bell. The cardioid polar pattern minimizes off-axis noise and feedback. The AP40 amplifier converts the microphones to low impedance, it regulates the voltage to each microphone, and with certain models creates a specific frequency curve. The combination results in pristine reproduction of brass and woodwind instruments for recording and sound reinforcement applications.
