PRODUCT INFORMATION

• The BasX A2L+ is a flexible two channel power amplifier that delivers 50 watts / channel into 8 Ohms and 90 watts / channel into 4 Ohms, all channels driven, with a rated THD+N of < 0.1%, and an A-weighted S/N ratio of 112 dB. The BasX A2L+ features a heavy-duty linear power supply, high-quality Class A/B amplification, transparent fault protection, and a trigger input and output. The BasX A2L+ offers individual unbalanced RCA inputs, so it can be used with almost any preamp or processor, and any AVR that has preamp outputs. Unbalanced passthrough outputs make it simple to chain multiple A2L+ amps together and a variable gain reduction adjustment simplifies matching levels between multiple stereo zones. Audiophile grade five way speaker terminals accept banana plugs, spade lugs, or bare wire. These features combine to enable the BasX A2L+ to deliver true audiophile performance and sound quality at an amazingly affordable price. The BasX A2L+ is the perfect combination of modest power, and true audiophile sound quality, in a compact form factor. The BasX A2L+ also includes several features that make it the ideal solution for powering multiple separate stereo zones.
