At the heart of the NT2A is the Australian designed and manufactured HF1 dual diaphragm capsule. The frequency and transient response of this transducer has been voiced to complement today's modern recording techniques, and yet still evoke the silky smooth character of the legendary microphones of the 50's and 60's. These features provide the flexibility and superlative audio characteristics that make the NT2-A one of the most versatile condenser mics available.
