A pre-amp very good. Everything has been thought, two types of input jack or XLR with gain, Thomann two types of phantom power (48 v for micro "condense" or 10 v for micros "electret") a complete equalization of 4 potentiometers (low, medium-low, mid, high), pad attenuation of -15 dB, low-pass, master volume, volume of the channel input and output end, a Thomann mute button filter and finally an output jack, XLR output, headphone output (mini-jack) and an additional DI output quality of the components is to visit this acoustic pre-amp is a Class A pre-amp, all in an anodized metal casing blue color with very practical dimensions 150 X 110 X 38 mm.
Operation is simple.
The sound is perfect, all the settings are there
The price may seem a bit high, but when the pre-amp is tested we understand that the price is justified, frankly I do not regret this purchase.
