The MPA Gold is defined by warmth, presence, clarity, and a performance that adheres to incredibly high standards with first-class features and components.Variable Input Impedance optimizes it for performance with a wide range of microphones. This infinitely adjustable variation dramatically alters the performance of the microphone and creates more sonic possibilities.The selectable Tube Plate Voltage function delivers a wide variety of tones. The tube circuit is differential, and provides the equivalent of a 300V power supply on the high voltage setting. With very low self-noise, the normal setting maintains classic tube preamp sounds.The MPA Gold's unique tube circuitry utilizes 2 - 12AX7A vacuum tubes and renders unsurpassed detail and clarity with a broad range of mics. It provides gain with controlled overload while maintaining the dynamic range of the previous stage.In addition to the large VU meters, the MPA Gold has Tube Warmth LED metering which measures the left and right audio channel levels. Average level attack and release are measured in milliseconds and the peak function has a 20-microsecond attack time. The analog meter range is switchable between -10dB and +4dBU. The High Pass filter is continuously variable from 15Hz to 150Hz.
