Frequently Asked Questions
While decent, it won’t match a high-end preamp; it's clean enough for most live scenarios but may exhibit a bit more hiss with very sensitive mics.
Absolutely, the XLR input handles standard microphone levels just fine; the preamp has enough gain to work well with most common vocal mics.
It’s mainly for preset editing via a computer; it doesn’t function as a full audio interface for recording vocals directly.
