Channels: 3; Power Output (All channels driven):
150 watts RMS per channel @ 8 Ohms & 250 watts RMS per channel @ 4 Ohms

The BasX A3 is a three channel power amplifier that delivers 140 watts / channel into 8 Ohms and 200 watts / channel into 4 Ohms, all channels driven, with a rated THD+N of < 0.02%, and an A-weighted S/N ratio of 112 dB. The BasX A3 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 A3 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 A3 to deliver true audiophile performance and sound quality at an amazingly affordable price.

The BasX A3 is the ideal choice to power a 3.1 channel system, to upgrade the front three channels of a surround sound receiver, or for anywhere where three channels of great sounding clean power are needed

Circuit Topology

“Why can’t we have amazing audio and video sound at prices that don’t threaten our mortgage?”As high-end audio chased an ever-shrinking market with ever-more-costly gear, the price of sonic nirvana shot out of reach. New enthusiasts shook their heads and thought, “You know, a soundbar and a receiver may not be that bad.” At the same time high-end audio prices were climbing, Dan Laufman and his team were helping some of the best names in audio manufacture their gear. Dan saw the inefficiencies in the system and the ever-climbing prices, and decided to do something about it. The result is Emotiva.
