Adding a separate amplifier is essential to experiencing
spine-chilling surround sound, and our NERO-XA5180 delivers on power. This Class
H amp supplies 150W to five separate channels, so each speaker in your surround
set up receives a generous amount of power rather than having to share power
with the sound array. When paired with great speakers, you'll hear music and
movie soundtracks with exceptional clarity and warmth, and the advanced
circuitry, wide bandwidth, and low distortion capabilities do their share in
providing sonic nuances that turn a decent home theater into a high-end
movie-theater level experience. This formidable home theater amp can be matched
with power-hungry in-wall or freestanding loudspeakers and is designed with a high-output
toroidal power supply. Custom heat sinks to keep things cool without the need for
noisy fans. The XA5180 also looks great in an equipment rack with its clean,
brushed metal finish and front panel status indicators that add a high-tech ambiance.
Flexible Connection Options
The NERO-XA5180 high current home theater amplifier includes
both balanced and unbalanced inputs for more flexible installation options and
cable runs. XLR inputs (balanced) include a ground wire, which makes it a good
choice for long cable runs, while unbalanced (RCA) provides a more reliable
signal on shorter runs.
Advanced Class H Hybrid Amplifier Technology
Our NERO-XA5180 is a Class H amplifier that combines the
benefits of Class A/B in a more efficient package. Class H amplifiers are a
variation of Class A/B amps but include high voltage and low voltage rails to
modulate power consumption. When power is running high, the amp switches to the
high voltage rails. When the amp is running low, it switches to the low voltage
rails. The result is more efficient, cooler temperatures, and a reduction in
power consumption while maintaining the warmth and accuracy of a true A/B amp without
the "digital" drawbacks (like interference) of Class D amps.
NOTE: The NERO-XA5180 features a brushed aluminum faceplate with a wax coating to repel fingerprints. Be careful when initially removing the amplifier from its packaging and during its placement, as the wax can scratch. We suggest wiping down the brushed aluminum faceplate using a lint-free soft cloth. This will help remove any dust or wax residue on the surface. Isopropyl alcohol or a multi-purpose kitchen or window cleaner applied to a clean cloth will remove fingerprints from the chassis.
