XPA-1L
Features
The XPA-1L Differential Reference™ Monoblock Power Amplifier features our fully discrete,
high-current, short signal path, class A/B output section, and all the advanced engineering
and high quality construction you’ve come to expect from Emotiva.
The XPA-1L also has an exciting new feature. Flip the front panel switch into the Class A/B
posiiton, and the XPA-1L is a superb sounding Class A/B amp, delivering 250 watts into
8 ohms (or 500 watts into 4 ohms) with amazingly low noise and distortion. Flip the switch
into the Class A position, and the XPA-1L delivers 35 watts of awesome quality pure
Class A sound. And, if you do need more than 35 watts, the XPA-1L automatically
transitions back into Class A/B mode to deliver its full rated power. This way you get
all of the sound quality of Class A with none of the limitations. (The XPA-1L will get
slightly warmer in Class A Mode, but it will never get dangerously hot or exceed CE case
temperature safety ratings.)
The XPA-1L: All of the benefits of pure Class A operation; and none of the drawbacks.
