• CEA-2006 Compliant Amplifier
• Pulse Width Modulated MOSFET power supply
• LED power (blue) and protect (red) indicators
• Stealth top mounted control panel
• Soft start turn-on
• 4, 3 or 2 channel operation
• Nickel-plated RCA level inputs
• Nickel-plated captive C-clamp terminals
• 3-way protection circuitry (thermal, overload, and speaker short protection)
• On-board differential inputs eliminates noise picked up by the signal cable
• Integrated Trans•ana technology simplifies the signal path of the amplifier allowing the signal to travel through the amplifier at a lower voltage. The result is greater reliability and exceptional sound quality
• MESHA3 reduces MOSFET temperatures, lowers distortion, increases durability, and prolongs the output device life span
• DSM (Discrete Surface Mounted Components) utilize 1% tight-tolerances improving efficiency of the circuit and lowers operating temperature and potential for noise - similar to circuit boards designed by aerospace manufacturers
• Built in NOMAD is a "real time" analog computer that protects your amplifier from shorting speaker wires and dangerously low speaker impedances
• Cast aluminum convection heatsink with DTM (Dynamic Thermal Management) evenly distributes excess heat across entire amplifier heatsink to efficiently keep the amplifier temperatures low
