The HPA-nxV200 R2 Signature amplifier module is the very latest design from Holton Precision Audio. Building on the very successful nxV200 module, of which hundreds of these modules have been sold worldwide. The new nxV200 R2 Signature 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. The nxV200 R2 also has been upgraded with four Nichicon audio grade 100uf supply rail decoupling capacitors and isolating supply rail resistor to form a RC filter for the Input/Driver stage, in addition to this the output stage has it's own 100uf audio grade capacitor for each output stage power transistor. The last update is the addition of a Common Mode Rejection Ratio nulling trimmer. This trimmer allows the adjustment of CMRR when the balanced input option is used. The CMRR is trimmed for best performance at the last stage of assembly and testing and should not need to be touched after this time.
