About the PREi
The EMM Labs PREi represents the pinnacle of analog preamplifier design, evolving from predecessors like the Meitner PA6i, PRE2, and PRE. Engineered in Canada with fully discrete dual-balanced Class A circuitry, Meitner Audio Architecture (MAA), contactless switching, software-driven MVControl³ all-analog volume control, third-generation MXPower³ resonant-mode power supply, and custom MCeraTek ceramic circuit boards for superior stability, low noise, and preservation of low-level details. Housed in a precision-machined aluminum chassis with OLED display, touchscreen interface, programmable inputs, volume presets, RS-232 control, and machined aluminum IR remote. Offers six stereo analog inputs (3x balanced XLR, 3x single-ended RCA) and three stereo analog outputs (2x balanced XLR, 1x single-ended RCA). Delivers exceptional performance with S/N >118 dB, THD+N <0.01%, and maximum 40W power consumption.
