The M900T is excellent in situations where flat frequency response, excellent transient response, and robust and detailed sound are required. The CharterOak M900T is a small diaphragm condenser microphone, which employs a vacuum tube head amplifier and Cinemag 2480 output transformer.
The microphone utilizes modified versions of our S-5 (cardioid), S-6 (hyper-cardioid), and S-7 (omni-directional) capsule types. All three of these capsules are shipped with each M900T head amplifier, and are easily interchangeable. Sequentially numbered matched pairs are available for stereo recording. The M900T is equipped with a 15dB pad facility, and a 6dB per octave bass roll off at 75Hz. It is delivered in a hard locking flight case with a windsock, shock-mount, and custom power supply, and is guaranteed for life.
