Description

The BasX A4 is a four channel power amplifier that delivers 100 watts / channel into 8 Ohms and 130 watts / channel into 4 Ohms, all channels driven, with a rated THD+N of < 0.02%, and an A-weighted S/N ratio of 115 dB. The BasX A4 features a heavy-duty linear power supply, high-quality Class A/B amplification, transparent fault protection, and a trigger input and output. High quality industry standard unbalanced RCA inputs enable the BasX A4 to be used with almost any preamp or processor and audiophile grade five way speaker terminals accept banana plugs, spade lugs, or bare wire. These features combine to enable the BasX A4 to deliver true audiophile performance and sound quality at an amazingly affordable price.

The BasX A4 is the perfect solution if you need a high quality amp to power your Dolby Atmos and DTS:X height channels. It is also an excellent choice to power your surrounds if you're building a new system and you've already committed to a more powerful amp, like our XPA-3, to power your front channels or to power two pairs of zone speakers.
