``Ability to go beyond the limits of a 4ch amplifier'' A high-performance DSP amplifier with performance comparable to that of a higher-end model.

A model with DSP added to the HELIX M4 amplifier. The DSP has a total of 10 channels, the amplifier is 100w x 4, and it is an excellent product that can even do britches! Last but not least, the most attractive feature is the price. The performance is better than the price, and this is our highly recommended amplifier!
