Trans•nova: patented output stage configured for "power gain" allows simpler front end circuitry, dramatically lower cross talk and noise.
NOMAD: Smart protection circuitry that prevents sonic degradation and accurately computes allowable device current for device voltage.
DIAMOND: combines the linearity of Class A with the headroom of Class B; provides up to 14dB additional dynamic range in amplifier front end.
Class-G Output Stage: Greatly improved efficiency, lower heat.
MOSFET Outputs: Deliver higher output current, rugged reliability, superb sound quality.
Balanced Inputs: Combo XLR & 1/4".
"No Touch" 5 Way Binding Posts: prevent shorting.
Dual Fan Cooling (variable speed).
Regulated Switching Power Supply: Lighter weight and efficiency
5 Year Warranty
