TRM 9m Tube Condenser Microphone

TRM 9 is an extremely high quality vacuum tube microphone featuring a special patented pure gold-coated large diaphragm capsule. Utilizing quality electronic circuitry that uses specially imported components plus output transformer,the TRM 9 condenser microphone has an extremely flat frequency response. Featuring a low cut filter and -10dB low frequency attenuation switches on the microphone body. The nine variations of polar pattern are available by adjusting the control knob on the dedicated phantom power supply for various recording situations. TRM 9 has a wide range of uses in professional situations such as studio recordings, broadcast & TV stations, live sounds, voiceovers and computer recordings.
