   • Offers a wide frequency response from 20 Hz to 20 kHz, ensuring natural and detailed sound reproduction across the entire audio spectrum.
4. High SPL Handling:
   • Capable of handling high sound pressure levels (SPL) up to 145 dB, making it suitable for loud sound sources without distortion.
5. Low Self-Noise:
   • Designed with low self-noise (16 dB SPL), providing quiet and clear audio capture, essential for professional recordings.
6. Superior Transient Response:
   • Captures fast transients accurately, making it ideal for percussion and plucked string instruments.
7. Switchable 80 Hz High-Pass Filter:
   • Reduces low-frequency noise and rumble, allowing for cleaner audio capture in various environments.
8. Switchable 10 dB Pad:
   • Provides an additional level of headroom when dealing with extremely loud sound sources, preventing distortion.
9. Modular Design:
   • Part of Audio-Technica’s modular microphone system, allowing users to interchange capsules with the AT4900b-48 microphone body to suit different recording needs.
10. Rugged Construction:
    • Built with a durable metal housing to withstand the rigors of professional use.
