The Matrix Audio MP-1 meticulously extracts the Acoustic Truth from musical signals. Through precision engineering and an advanced architectural design, it renders audio with striking authenticity and depth.
The MP-1 preamplifier operates on a fully differential transistor input stage that provides superior linearity and low noise characteristics, allowing for clear signal processing across a wide dynamic range. Its output stage employs a high-bias current pure Class A configuration, which minimizes crossover distortion, while a robust low-noise power supply can operate up to 60V to facilitate exceptional dynamic responsiveness. The output DC servo circuit regulates offset to within 1mV, ensuring a consistent equilibrium without coupling capacitors that could compromise frequency response accuracy. Furthermore, the architecture of four independent fully balanced amplification units enhances the signal integrity, converting RCA inputs to a bipolar signal for effective common-mode noise rejection. This meticulous design allows the system to maintain consistent amplitude levels across multiple inputs, while a voltage-divider volume control using precision resistors and sealed reed relays ensures minimal impact on sound quality and superior channel consistency.
