TOPPING PA5 High-Performance Power Amplifier (Apos Certified Refurbished)

Fully balanced, super efficient  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. Fully-balanced Class D amplification 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. High output power The PA5 can output 140W x2 @ 4Ω load. This highly powerful output is sufficient to drive most speakers and applications. Balanced TRS inputs Connect multiple sources via TRS balanced inputs. The balanced input option eliminates potential groun
