Nuprime PRA-9X preamp with MM phono preamp
The NuPrime PRA-9X is a fully balanced preamplifier designed for ultra-low distortion (THD+N of 0.0004%) that includes a MM phono input and a 6.3mm headphone output. There are a variety of settings for matching different MM cartridges.
NuPrime PRA-9X is a pre-amplifier with a fully balanced design and includes a MM phono input. The input and output use a special audio Relay Switch, which has the lowest interference and highly accurate transmission, to switch the source.
The phono input has a variety of settings for input resistors and capacitors to match different MM cartridges. PRA-9X phono amplifier is a 2-stage RIAA amplifier that utilises NJR MUSES8820 audio quality op-amp to provide an accurate RIAA curve and low distortion at high amplification and performance.
Line Outputs include four NuPrime’s new ultra-low distortion amplifier modules (THD=0.0004%) composed of MUSES8820 op-amp in a new amplifying circuit. It has excellent ultra-low distortion and high driving force characteristics.
