Fully balanced, super efficient\u00a0<\/b><\/h4>\n

The TOPPING PA5 is a fully balanced Class D power amplifier–an affordable and efficient option for powering your bookshelf or floor stand speakers. As a balanced amplifier, it powers each incoming channel with a separate amplifier chip. As a Class D amp, it uses far less power than Class A amps, making it super efficient.<\/span><\/p>\n

Fully-balanced Class D amplification<\/b><\/h3>\n

The newly developed Class-D amplification circuit uses multiple novel optimization techniques to fully push the performance and output power to the maximum. The new circuit provides crisp, clean, and deep sound with a completely inaudible noise floor. The fully balanced structure results in zero hum, zero noise, and zero ground loop noise.<\/span><\/p>\n

High output power<\/b><\/h3>\n

The PA5 can output 140W x2 @ 4\u03a9 load. This highly powerful output is sufficient to drive most speakers and applications.
\n<\/span><\/p>\n

Balanced TRS inputs<\/b><\/h3>\n

Connect multiple sources via TRS balanced inputs. The balanced input option eliminates potential ground loop problems, providing pristine audio without hum.<\/span><\/p>\n
