The Topping PA7 Plus is a powerful amplifier based on Class D architecture and benefits from intelligent design. Thanks to this, it is able to develop significant power while maintaining low distortion. The technologies used provide clear, accurate and deep sound reproduction. In addition, the PA7 Plus’ balanced design provides effective transmission noise suppression.
The PA7 Plus’ distortion performance is close to that of a very good DAC. It always remains extremely low before clipping, ensuring consistent playback quality regardless of volume level.
Topping PA7 Plus is equipped with dual input jack. There is a 6.35mm TRS XLR/Jack combo for balanced transmission and a stereo RCA input for single-ended transmission.
Equipped with a 12V trigger input, the PA7 Plus can be connected to other devices to benefit from the auto-on/off function of the configured system.
The Topping amplifier is equipped with a volume control. However, it can be bypassed to use the PA7 Plus as a power amplifier by connecting an external preamplifier (not included) to it.
