To connect the sources, the novelty offers two analog inputs on RCA connectors. There is even a pre-amp output implemented on the 3.5mm mini jack connector. The amplifier develops 21 Watts in each channel when operating on a load with a nominal resistance of 8 ohms and 40 Watts at a load of 4 ohms. High-quality screw terminals are provided for connecting acoustic systems.
