The RODE K2 is one amazingly quiet and versatile tube microphone! The ultimate in pure rich tube sound and performance, the K2 delivers super low self noise (10 dBA), high max SPL (162 dBA), and mega wide dynamic range (150 dB). Featuring totally variable polar pattern control for an unbeatable combination of flexibility and power, the K2 s legendary sound quality inspires those magic takes in even the most demanding recording applications. The sound. The new Australian designed and manufactured TYPE HF1 dual diaphragm capsule represents R DE s finest transducer technology. Coupled with their most advanced high output electronic tube circuitry, the K2 brings out every little detail, every nuance, every whisper, while handling even the loudest source material. From cranked up amp stacks, to belting voices. From opera to punk rock, concert drums to orchestral double bass, the K2 is literally in a class by itself.
