Professional Tube Condenser Microphone The Audio2000’S® ATM1104 tube condenser microphone is a versatile professional tube condenser microphone with a 12AT7 vacuum tube pre-amp. A power supply & control box is supplied to provide the phantom power and nine polar patterns. The polar patterns, selected from the front panel of the power supply & control box, include three common patterns (omni-directional, cardioids, and figure-8) and six intermediate stages between each of the above three common patterns (three intermediate stages between the omni-directional pattern and the cardioids pattern; three intermediate stages between the cardioids pattern and the figure-8 pattern). A dual 1” gold sputtered 5-micron diaphragms in a shock-mount capsule eliminates unnecessary low frequencies while provides a full-body sound and a warm tone and a high maximum input sound pressure level (S.P.L.), making the ATM1104 tube condenser microphone a perfect choice for any professional studio, concert halls, and stage live sound applications. With the supplied external shock-mount suspension, the vibration and handling noise is virtually eliminated. This external shock-mount also facilitates the ATM1104 to be mounted in any position and orientation for recording and live sound applications.
