Amplifier Topping PA3 Silver
Усилитель Topping PA3 предназначен для использования с пассивными акустическими стерео системами в диапазоне 4 — 8 Ом. Основным его преимуществом перед конкурентами являются высокая выходная мощность (до 80 Вт) и пара аналоговых входов, что позволяет его подключить сразу к двум источникам звука.

The Topping PA3 amplifier is designed for use with passive stereo speakers in the 4-8 ohm range. Its main advantage over competitors is its high output power (up to 80 W) and a pair of analog inputs, which allows it to be connected to two sound sources at once.
Now there is no need to switch cables between two audio sources. Two RCA inputs allow you to freely use two sources, while switching between them with just one push of a button on the front panel of the device. So switching sound from a TV or set-top box is now incredibly easy.
The PA3 is a Class D digital amplifier which means it is small, powerful and consumes little power. The power supply in it is remote, the amplifier itself takes 24-32 Volts.
It is built around TDA7498E, which provide high output power and good dynamics. According to the manufacturer, it is just enough for speakers up to 10 inches.
