See below, but more interesting is two amplification systems (transistor / light) mixed, and 2 / 2 out

for each input: low-cut filter 80 Hz, inverstion phase reamplify padding-20db for a strong signal, phantom power supply.

input combo jack / XLR, each selectable output jack / XLR

UTILIZATION

Super simple, you activate the switch options, you turn the knob to the setting, and voila.

English manual.

SOUND QUALITY

Super good, low-cut filter filter sounds too rich grave of my guitar.

Add a can of light amplification adds something or more.

OVERALL OPINION

I've had one myself, I took it for double amplification system, the two see, and options and especially the phantom power supply for my condenser microphone (not tested since lent my dad for now)

I do not regret, to be redone.
