I bought this mixer for versatile use:
_ Sound systems of groups (the main purpose of this type of product)
_ Sound systems for mobile dico
_ Fi amp
we will start with the positives:

for less than € 300 is a good deal
mixing is relatively accurate and amp are good qualities
buses are simple and can be connected to other amplifiers on the front and back just
the multi-effects and sounds good practice
the sound is very clean with instruments
equalizer is very useful although it lacks the presence of the 32Hz band, the filter low blow on channels 1,2,3 and 4 up for this lack
forced ventilation is silent

in negative are:

the amp is sorely lacking the power 2X250W rms are not really usable because giving 1% distortion, it takes more in the 2X125W RMS into 4 H.

the limiter is useless because it is active on the distortion is already clearly audible

Even if this console to all that I need a single device (mixer, effect, equalizer and amplifier) ​​in a reasonable volume, the quality of the power amplifier and ask me that problem.
