FAQs
Can I test a Shure SM7B in the browser? +
Yes, but the browser sees your audio interface, not the XLR microphone directly. Select the interface input and test level plus local playback.
Why is my SM7B quiet in browser tests? +
The SM7B needs enough clean gain from an interface or inline booster. Low level does not automatically mean the microphone is broken.
Should I buy a new audio interface for an SM7B? +
Only when routing is correct and the current interface cannot provide usable gain without excessive noise. Check cable and booster power first.
