Indicates the frequency range that a microphone can capture and is expressed in Hertz (Hz). The more balanced the range, the more natural and clear the sound.

Usage examples:

• 100 – 10,000 Hz to 200 – 12,000 Hz: Emphasis on speech intelligibility, with limited low and very high frequencies.
• 50 – 14,000 Hz to 80 – 16,000 Hz: Balance of volume and clarity. Ideal for live performances and dynamic microphones.
• 40 – 15,000 Hz to 50 – 18,000 Hz: Rich, natural vocal sound. Suitable for podcasts, radio, and streaming.
• 20 – 18,000 Hz to 20 – 20,000 Hz: Full spectrum with high detail and "air". Ideal for studio recording.
• Below 20 Hz & above 20,000 Hz: Extended technical range for specialized studio applications.

The sensitivity of a microphone indicates how strong the signal it produces is when recording a sound. It is measured in mV/Pa or dBV/Pa.

• High sensitivity: The microphone can capture very low sounds, but it may be more sensitive to ambient noise.
• Low sensitivity: It records louder sound sources without distortion, but requires more amplification from the preamp.

In general, condenser microphones have higher sensitivity than dynamic ones.
