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!
Circuit Topology
- The BasX A11 is an eleven-channel power amplifier. The BasX A11 combines classical audiophile amplifier architecture, based on a heavy-duty Class H 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 and high efficiency at a truly reasonable price
