Overview

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.

Features

Sound Quality First
Designed first and foremost to sound great in all types of audio systems with all types of music. Great sounding Class A/B output stage ensures smooth, detailed sound and incredibly natural imaging, without a trace of harshness or strain. Low noise, wide bandwidth design, and a highly optimized input stage, lets you hear everything your high definition sources have to offer. Totally stable with real world speakers in real systems; not just on a test bench.
Solid Engineering and Quality Construction
A heavy duty linear power supply with an oversized toroidal power transformer delivers plenty of current to drive even difficult speakers. Top quality parts and construction throughout deliver years of reliable trouble-free service. Heavy steel chassis with milled aluminum faceplate offers strength and rugged good looks. Double sided FR4 circuit boards, with plated-through holes, help optimize signal paths and minimize the need for point-to-point wiring.
Flexible Power and Control Options
The BasX A2L+ is designed to operate on either 115 VAC or 230 VAC at 50/60 Hz and will automatically detect and configure itself for the proper line voltage. The remote trigger input and output allow the BasX A2L+ to control and be controlled by other trigger-enabled equipment and the Auto-On feature enables the BasX A2L+ to turn on automatically when it senses an input signal.
Flexible Input Options
Unbalanced stereo inputs work with a wide variety of sources. A pair of stereo unbalanced passthrough outputs enable you to chain multiple amps together; and a variable input gain adjustment facilitates matching levels in multiple stereo zones.
Audiophile Quality Speaker Connections
Heavy duty insulated five-way speaker binding posts allow you to use a wide range of speaker cables with bare wires, spade lugs, or banana plugs.
