Rode NTK Class A Large Diaphragm Tube Microphone
The RODE NTK is the multi award-winning Class-A tube microphone that has found a home with tens of thousands of professionals around the world. The heart of the NTK is the Australian designed and manufactured HF-2 capsule. The electronic circuitry complementing this very sensitive transducer includes a hand-selected twin-triode 6922 valve and audiophile grade components and lay-out. The result is an ultra-wide dynamic range, very low noise, and stunning tube warmth. The NTK's rich valve sound is ideal for vocals, acoustic instruments, drum overheads, guitar amps and pianos.
