ART Digital MPA - Professional 2-Channel Mic Preamp with A-D Conversion
The Digital MPA is one of the finest microphone pre-amps with digital capability available today. The enhanced discrete front end maintains every nuance, revealing incredible dynamic range. Our unique tube circuitry, using two 12AX7A tubes, renders unsurpassed detail and clarity with the broadest range of microphones. Take advantage of this world class processing via the analog and digital outputs. AES/EBU, S/PDIF. TOSLINK, and ADAT interfaces allow connection to the broadest range equipment. The Digital MPA provides 24 bit or it can adapt to 16 bit applications with the push of a button. The A/D is front panel adjustable from 44.1 to 96K or syncs to ADAT or external word clock (32KHZ to 100KHz).
The Digital MPA circuitry is a hybrid design utilizing the strengths of all available technologies. The active balanced triple-differential transistor design with local feedback provides excellent CMRR and lower noise than the typical transformer/tube front end. The 12AX7A tube section running on a regulated supply provides gain while maintaining the incredible dynamic range of the previous stage and controlled overload characteristics. Insert jacks between the analog and digital section allow patching in additional signal processing before entering the digital realm. Separate balanced analog outputs and multiple digital outputs possess individual level controls allowing simultaneous use. While the new Digital MPA accepts full line levels, an additional high-Z ¼” input makes the Digital MPA the perfect DI in studio and live applications.
