A manual, a little anorexic especially on the compressor ...
If IN and OUT and basta!
What you ask for? a cheap preamp that preamplifier. TB on this one the 202 was completely successful operation. He gives her a stunning, breathless. I did not test any AVALON, but here I have for my sub.
There is a possibility to refine the equalizer and a compressor which I have not yet grasped all the subtleties. These two stories are detachable so no problem if you do not want a tube amp that gives fishing to your voice. I have not tried with an instrument, because it is rarely necessary preamplifier for my instrumentals.
There is a button ON OFF accessible ... It is these devices that do not remain switched on unnecessarily!
A € 160 with our friends the Germans .. KOLOSSAL! Put me 3 boxes!
