- Pristine Input Stage
The input stage of the MPA1 is designed with high-voltage headroom (+29 dBu) and a single-stage gain control to maximize signal-to-noise ratio. The MPA1 maintains superb noise performance across the entire gain range (74 dB) by utilizing precision-matched, low-noise, transistor quad-arrays. A servo-controlled circuit minimizes DC-offset and maximizes headroom. - Complete Low Frequency Response
The MPA1 exhibits exceptional low-frequency performance with a clever dual-capacitor AC-coupled design. This dual-capacitor design defeats the limitations of single-capacitor AC-coupled designs, achieving an exceptionally low corner-frequency with excellent subsonic phase accuracy. - Innovative Stepped-Resistor Gain Control
The gain control of the MPA1 is completely unique. The gain is controlled via a 38-position, switched-resistor ladder, set up in a continuously rotating orientation via relay control. This gain control circuit offers 2 dB per step, 0-74 dB of gain without attenuation, and inter-channel gain precision of +/- 0.03 dB. A make-before-break scheme creates a silent switching circuit. - Elegant Phantom-Power Protection
The transistor stage is protected from phantom-power surges with an ultra-fast, multi-stage protection circuit. This circuit utilizes the high-speed capabilities of low-capacitance Schotky diodes and the high-current capabilities of Transient Voltage Suppression (TVS) diodes to absorb the phantom-power surges caused by shorts and plugging/unplugging microphones with 48V powering. This circuit is pre-biased so that it is isolated from the circuit in normal operation and activated when a surge occurs.
