Mic / Line and high impedance instrument input.
Input gain and output alim48V, phase inverter
<span style="font-family: Arial,Helvetica,sans-serif; color: #ffffff;">Preamp / EQ "Class A".</span>
Ultra simple, no need for manual.
With regard to the sound it's very upscale, it colors the same way as the original.
On vocals it's killing
Guitars, bass, kick, snare idem
The sound of this machine is really unusual I've never had this sound with any other preamp fortunately.
Even if the price is a little girl I do it again without hesitation that choice with your eyes closed.
