The Emotiva BasX A3+ is a high-performance three-channel power amplifier designed to deliver clean, powerful and transparent sound for home cinema and high-fidelity systems. With a robust linear power supply, high-current output stages and advanced thermal protection, the A3+ provides exceptional control and dynamic capability across demanding loudspeakers.
High-current, low-noise design
The BasX A3+ features a heavy-duty toroidal transformer, optimised Class A/B amplifier modules and short signal paths for low distortion and excellent channel separation. The result is wide-bandwidth, highly transparent performance with impressive headroom.
Engineered for reliability
The A3+ includes output protection, thermal monitoring and carefully controlled startup sequencing. Rugged steel chassis construction ensures long-term durability while reducing mechanical resonance.
