The XPA-1 Gen3 is a fully modular audio power amplifier with a high-efficiency switch mode power supply (SMPS), independent, fully discrete, dual differential, high current, short signal path Class A/B amplifier modules, Optimized Class H™ power supply topology, and microprocessor-controlled fault protection.

2009年1月5日 · The XPA-1 is Class AB like the XPA-2, and looks similar inside. Rather than the two sides of the amp driving two independent channels, the XPA-1 uses the two “channels” of the amp to drive the hot and cold legs of the balanced input signal.

2014年10月20日 · Design and Setup of the Emotiva XPA-1 Gen 2 Monoblock Power Amplifier. The XPA-1 is a balanced, discrete Class A/B monoblock amplifier. It features XLR and RCA inputs on the rear, with a switch to toggle between the two inputs. 12V triggers have a 3.5mm input and output, so you can chain two XPA-1s together if you wish.

2014年7月17日 · The XPA-1 is the most powerful Class A/B amplifier that Emotiva makes. We know it has raw power, but does it also have grace and finesse to go along with brute force? The full Review of the Emotiva XPA-1 Gen2 Monoblock Amplifier with Bench test analytics to be published shortly!
