Mixer Features

The type of circuitry the mixer is comprised of as either Analog or Digital.

THD (Total Harmonic Distortion)
The amount of change in harmonic content of the signal as it is amplified. A lower figure indicates less change and a more accurate amp. THD below 0.10% is inaudible.
The number of individual channels that can simultaneously pass audio.
The ability to mount the mixer to a 19" rack.
Phantom Power
