Emotiva A2


Channels: 2; Power Output (All channels driven):
170 watts RMS per channel @ 8 Ohms & 320 watts RMS per channel @ 4 Ohms

The BasX A2 is a two channel power amplifier that delivers 160 watts / channel into 8 Ohms and 250 watts / channel into 4 Ohms, with a rated THD+N of < 0.02%, and an A-weighted S/N ratio of 112 dB. The BasX A2 features a heavy-duty linear power supply, high-quality Class A/B amplification, transparent fault protection, and a trigger input and output. The BasX A2 also offers a convenient feature that allows the amp to switch on when an audio signal is detected at its input – which is especially useful if your preamp or receiver doesn’t offer a trigger output. High quality industry standard unbalanced RCA inputs enable the BasX A2 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 A2 to deliver true audiophile performance and sound quality at an amazingly affordable price.

The BasX A2 the ideal amplifier to serve as the foundation of a great sounding stereo system, to power the front main speakers on a surround sound system, or to upgrade the front left and right channels of your favorite surround sound receiver.

Circuit Topology

  • The BasX A2 is a stereo power amplifier. The BasX A2 combines classical audiophile amplifier architecture, based on a heavy-duty linear power supply, and a carefully designed high current short signal path Class A/B output stage, with advanced microprocessor-controlled monitoring and protection circuitry, to deliver superb sound quality at a truly reasonable price.

“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.
