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.

Incredibly low distortion level
The PA7's performance in terms of distortion is close to that of a very good DAC. It always remains extremely low before clipping, ensuring a constant reproduction quality whatever the volume level.
Impressive power
The PA7, despite its compactness, is capable of delivering a significant power. It will indeed be able to deliver no less than 2x200W under 4Ω (1% THD+N) or 2x125W under 8Ω (1% THD+N). It is thus capable of powering greedy audio systems without difficulty while offering a beautiful dynamic.
Single-ended & balanced outputs
The Topping PA7 provides a double input connector. There is an XLR / Jack 6.35mm TRS combo for balanced transmission and a stereo RCA input for single-ended transmission.
Volume bypass
The Topping amplifier has a volume control. It is however possible to bypass this control to use the PA7 as a power amplifier, by associating an external preamplifier (not supplied).
12V Trigger
Equipped with a 12V trigger input, the PA7 can be connected to other devices to take advantage of an automatic on/off function of the system set up.
