Emotiva BasX A11 Power Amplifier

The BasX A11 is an eleven-channel power amplifier that delivers 105 watts/channel into 8 Ohms and 140 watts/channel into 4 Ohms, all channels driven with a rated THD+N of < 0.1% and an A-weighted S/N ratio of <115 dB. The BasX A11 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 A11 to be used with almost any preamp or processor. Audiophile-grade five-way speaker terminals accept banana plugs, spade lugs, or bare wires. These features combined allow the BasX A11 to deliver true audiophile performance and sound quality at an amazingly affordable price.

The BasX A11 is a great choice if you’re looking for a high-quality power amp to pair with a pre/pro, like our MC1, to power all the speakers in a 7.1.4 channel system. Because the A11 provides so many channels of amplification in a single chassis, it also allows some other interesting connectivity options, such as powering the channels in a formidable 7.1 system with bi-amped main LCR speakers!
