About the NuPrime-X Fusion-3X
The NuPrime-X Fusion-3X is a three-channel Class D power amplifier from the Fusion Series, built for both stereo music and home theater, with 160W into 8Ω and 310W into 4Ω per channel. It drives speakers down to 3 ohms and can briefly sustain loads down to 2 ohms. At HiFi Boutique it ships free anywhere in the USA, with sales tax already included.
Why Choose the Fusion-3X
Fusion Series amplifiers integrate the power supply with the Class D amplifier circuit. Each channel has its own supply with six 2,200µF capacitors and a 15A-grade high-frequency filter, reducing power noise and crosstalk, and capacitors placed directly in the amplification circuit supply energy on demand.
Switching at 700kHz cuts MOSFET temperature by 30%, according to NuPrime. The input circuitry is fully balanced, and the power and Class D modules sit in custom metal enclosures that shield them from electromagnetic interference and prevent mechanical hum. Each channel has its own protection circuit that disconnects the speaker output if a fault occurs.
