FAQs

Q: Why use a matched pair instead of two regular C451Bs?
A: Stereo recording needs balance. A matched pair ensures tonal consistency between left and right channels—no guesswork.

Q: Is this mic only for instruments?
A: It’s built for instruments and incredibly percussive and acoustic sources. While not a typical vocal microphone, it is suitable for specific ambient vocal applications.

Q: Can it handle loud instruments?
A: Definitely. Its -20 dB pad can take high SPL from drum kits or brass without a sweat.

Q: How do the filters help?
A: The two low-cut filters help control unwanted low-end, which helps clean up rumble or stage noise.

Q: Is it easy to set up for stereo recording?
A: Yes. The included stereo bar and measurement documentation facilitate easy alignment and phase accuracy.
