The nxV800 is designed as a ultra high performace, high end audio amplifier in the Recording Studio's, Audiophile Amplifier's, Home Theatre and Sub-Woofer Amplifier's

The nxV800 has XLR Balanced inputs as standard and it can be configured for RCA single ended input as well.

It has all the latest advancements packed into the main PCB.

• Two Stage Nested Feedback Network
• Complementary Folded Cascode Input stage
• Improved Gate output stage protection
• The option of separate power supply rails for the Input and Driver stages
• Lower overall Global Feedback compared to the HPA-nxV500
• Very slim and compact design

The performance of this amplifier is truely awesome and unlike a lot of amplifiers these days. The power ratings are continuously rated sine wave into a resistive load.

• Featuring Balanced XLR and Single Ended RCA input stage.
• Can be power from separate power supplies for the Input and Driver Stage
• Very low noise and distortion
• Unconditionally Stable
• Extra Heavy Duty three ounce copper printed circuit boards.
• Gold Immersion copper track plating
• Rugged high performance Toshiba MOSFET output stage.
• RoHs Compliant
• Very easy to install and get going
• Sound quality and reliability rivaling the best in the world
