HPA-NXV200L R4.1 - Basic Version Amplifier
The HPA-nxV200L R4 Signature amplifier module is one of the latest designs from Holton Precision Audio. Building on the very successful nxV200 module, of which hundreds of these modules have been sold worldwide. It has been updated with a brand new PCB design, featuring dual rail supplies for the Input/Driver stage and separate isolated supply for the output stage. Single common supplies can be used by default if so desired. This version of the NXV200L R4 uses Single Die Lateral MOSFET pair for a more conservative power output of 55 Watts RMS into 8 ohms and 90 watts RMS into 4 Ohms. This version of the NXV200L R4 also now has XLR balanced input just like its bigger higher powered module using the Dual Die Lateral MOSFET's.
