I don't know if my review transmitted, so I am sending it again. The Acus-One 6t Amplifier appears to be very well designed and engineered.
Main features are: 1x instrument channel, 2x microphone channels, and 1x auxiliary channel with RCA connectors for the inclusion and mixing of backing tracks etc.
It is well constructed with a wood finish, metal front grill, a robust top carrying handle, and at 12kgs. it is very easy to transport.
Main benefits are that each channel is very easy to set up and balance, each having its own gain, pre-amp, reverb and volume controls, which in turn feed into a master volume control.
I have used the Acus-One 6T amplifier for individual practice, group practice and live performance. There is virtually no background noise and the sound is warm and clear. This gives me great confidence; I am very pleased and have no hesitation in recommending this amplifier as a class piece of equipment.
