TOPPING PA7 PLUS Amplifier Class D Balanced 2x245W 4 Ohm Silver

TOPPING PA7 PLUS Amplifier Class D Balanced 2x245W 4 Ohm Silver
The Topping PA7 Plus 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 Plus provides effective transmission noise reduction.

Incredibly low distortion level

The PA7 Plus'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 Plus, 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 Plus 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 Plus as a power amplifier, by associating an external preamplifier (not supplied).

12V Trigger

Equipped with a 12V trigger input, the PA7 Plus can be connected to other devices to take advantage of an automatic on/off function of the system set up.

Topping PA7 Plus review by Audio Science Review (Amir)

Even though the PA7 Plus is based on a commercial amplifier IC, it is clearly that significant engineering optimizations have gone into the design to produce such a low noise and distortion amplifier. The package is excellent and power supply quite hefty to enable very high power output (nearly 400 watts combined at 4 ohm!). I am happy to add Topping PA7 Plus to my recommande list. "
