SM58 frequency response
Check out how the SM58’s carefully crafted frequency response delivers the warmth and clarity you want in a vocal mic and rejects the audio clutter you don’t.
Every SM58 Shure manufactures must pass a frequency response test to ensure the consistency that vocalists and engineers rely on night after night.
- Low-cut roll off reduces handling noise, wind noise and plosives.
- Smooth mid-range adds warmth and depth to the vocal range.
- Presence peak increases intelligibility for speech and enables vocals to cut through the mix of amplified instruments.
