The RØDE's NTK Valve 1" condenser microphone is a large-diaphragm condenser microphone with Class-A valve electronics, which produces a warm sound. The NTK is designed for vocal and general instrument recording, with a cardioid polar pattern that provides the sound qualities found in higher-priced tube microphones. A mylar dual-diaphragm sprayed in gold provides transparent signal reproduction and a wide frequency response in the capsule. A hand-selected twin-triode 6922 valve and audiophile grade components make up the electrical circuitry that complements this extremely sensitive transducer. As a result, the tube warmth is outstanding, with an ultra-wide dynamic range and low noise.
