Emotiva A500 5-Channel Power Amplifier

Overview

The Emotiva A500 offers all the essential features that make a great audio component. The circuitry in the BasX A-500 features a heavy duty linear power supply, great sounding high-current short signal path Class A/B amplifier modules, a trigger input and output, and industry standard unbalanced audio inputs. It also includes audiophile-quality fault protection that’s completely transparent in normal operation, yet protects the A-500 and your other equipment from common fault conditions.

 

Specifications

Circuit Topology

The BasX A-500 is a five channel power amplifier. The BasX A-500 combines classical audiophile amplifier architecture – based on a heavy-duty linear 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 at a truly reasonable price.
