Overview

The kind of amp that fits your system today and still makes sense tomorrow.

The BasX A2+ is a two-channel stereo power amplifier that brings real headroom and control to music and home theater systems without adding complexity. It delivers 160 watts per channel into 8 ohms and 250 watts per channel into 4 ohms, powered by a heavy-duty linear supply with an oversized toroidal transformer and a refined Class A/B output stage for clean, dynamic sound. Setup is refreshingly flexible too, with balanced XLR and unbalanced RCA inputs, plus trigger in and out for easy integration.

Common uses

• Build a dedicated two-channel system with a stereo preamp or DAC

• Upgrade the front channels of an AVR or stereo receiver with preamp outputs

• Power a second zone with true hi-fi clarity

Features

Smooth Class A/B Sound
This two-channel Class A/B amplifier is designed to sound smooth, detailed, and natural, with confident speaker control and no added edge. The A2+ uses a refined Class A/B output stage and wide bandwidth design to keep things clean and composed.
Heavy-Duty Linear Power
A heavy-duty linear power supply with an oversized toroidal transformer delivers plenty of current for real-world speakers. The goal is simple: consistent, confident performance when your system starts asking for more, including with 4 ohm loads.
Built for Real-World Reliability
Quality parts, careful internal layout, and solid construction are baked into the design. The heavy steel chassis with a milled aluminum faceplate adds strength and a clean, classic look, and it’s built to deliver years of reliable service.
Easy System Integration
Connect to a stereo preamp, surround processor, or any AVR with preamp outputs using balanced XLR or unbalanced RCA inputs, one per channel. A standard trigger input supports system control, and the A2+ can also be set to turn on automatically when it senses an audio signal, with automatic 115V/230V operation for worldwide setups.
Transparent Protection
Microprocessor-controlled monitoring and protection are designed to stay out of the way during normal listening, while guarding against common fault conditions. It’s backed by Emotiva’s 3-year warranty and supported by the U.S.-based team in Franklin, Tennessee.
