Emotiva BasX A‐3

The BasX A3 is a three-channel power amplifier that delivers 140W per channel into 8Ω and 200W per channel into 4Ω, all channels driven, with a rated THD+N (Total Harmonic Distortion plus Noise) of <0.02%, and an A-weighted signal-to-noise ratio of 112dB. The BasX A3 features a robust linear power supply, high-quality Class A/B amplification, transparent fault protection, and trigger input and output. The standard high-quality unbalanced RCA inputs allow the BasX A3 to be used with virtually any preamp or processor, and the audiophile-grade five-way speaker binding posts accept banana plugs, spade lugs, or bare wire. These features combine to allow the BasX A3 to deliver true audiophile performance and sound quality at an incredibly affordable price.
