I have become aware of the company Acus and good price by positive tests. From an amplifier of this size one would expect as high a volume. The sound is very clear and punchy. The Hall of the sound also gets a nice depth. Operation is simple, handling well. The build quality is outstanding, the design appealing. A jazz guitar with clear sound can be connected with no risk. Ditto can be instruments also slimming through a microphone. As the song comes across, I have not tested, but again I'm expecting a good result. For this purpose a lineout / Aux comes for PA Anyone looking for a inexpensive, handy amplifier, is very well served by the Acus 5 Wood. For a little over 100 euros you get even a third channel, an advanced equalizer and 50 watts more in Acus 6 Wood.
