HPA-NXL300 R3 Amplifier Module - Coming Soon!
A new Lateral MOSFET version of the NXV300 module is coming soon!
The nxV300 R2 audio amplifier module is based on the high performance nxV500 R2 module. Unlike the nxV500 which has eight Toshiba output devices this version has four high performance Toshiba MOSFET's in it's output stage. Making it a much more compact but no less powerful. Boasting a power output of around 200 watts RMS into 8 Ohms and 350 watts RMS into 4 Ohms.
It also has XLR Balanced input which can be easily configured for RCA or unbalanced input.
The sound quality is in the same league as the very popular nxV200 and the nxV500 modules, making it an ideal companion to the nxVxxx range of amplifiers.
The HPA-nxV300 R2 modules comes fitted with Nichicon audio grade capacitors and are also supplied with the output stage silicon insulation washers.
The Printed Circuit Board is a double sided plated through hole and SMD extra heavy duty 2 ounce copper foil with Gold immersion plating and the layout includes a low noise ground plane on the underside of the PCB.
Like all of the R2 modules in the nxV range it has the capability of using separate power supplies for the input and drivers stages.
