ONYX MIC PREAMPS: Studio Preamp Performance in a Compact Mixer.
Solving this paradox, the Onyx mic preamp builds upon our already very impressive XDR mic preamp design (found in our VLZ3 mixers) and adds custom high-performance IC chips developed specifically for low-noise, high-headroom audio. The end result is a level of accuracy and transparency unsurpassed even in expensive esoteric standalone models—as well as gobs of dynamic range (yes, that's the technical term).
Specifically, the Onyx mic preamp delivers outstanding, verifiable specs like 123dB total dynamic range, –129.5 dBm Equivalent Input Noise, and 0.0007% Total Harmonic Distortion. Onyx mic preamps also address things like input impedance and linearity, maximum input level handling at low gain settings, shielding and grounding effectiveness, overload recovery, and radio frequency interference better than any preamp in Mackie history. And because Onyx mic preamps are designed for use at "real world" gain settings, they'll easily handle anything from +22 dB line level down to microvolt-level signals from a ribbon mic, without adding noise.
