TOPPING PA7 Amplifier Class D Balanced 2x200W 4 Ohm Silver
The Topping PA7 is a powerful amplifier, based on a Class D architecture and benefiting from an intelligent and particularly careful design. It is thus capable of developing a significant power while maintaining a very low level of distortion. The technologies used ensure a clear, precise and deep sound reproduction. In addition, the balanced structure of the PA7 provides effective transmission noise reduction.
