The BasX A-5175 is a five channel power amplifier that offers true audiophile sound quality at an affordable price. The BasX A-5175 includes a carefully chosen set of important features, including high-quality Class A/B amplification, a heavy-duty power supply, industry standard unbalanced audio inputs, transparent audiophile-quality fault protection and a trigger input and output. Modern manufacturing techniques, and careful design and parts selection, have enabled us to deliver all of this performance and great sound quality in the BasX A-5175 at a far lower price than you might imagine.

The BasX A-5175 delivers 175 watts RMS per channel at less than 0.1% THD into 8 ohms (two channels driven); THD+N of less than 0.07%; and a signal to noise ratio of 115 dB referenced to full power. The BasX A-5175 has plenty of power to drive even inefficient speakers, and to fill large rooms with awesome sounding music. This makes the BasX A-5175 the ideal amplifier to power a great sounding 5.1 channel surround sound system, a great way to upgrade the power amplifier section of your AVR, and a perfect companion to the MC-700 surround sound processor.
