Overview
The MBA-148 houses a mono-block amplifier that provides extremely clean state-of-the-art power with unexpected sound depth and musical clarity. It accepts any volume-controlled line-level input and runs on super-quiet 15 VDC power.
Advanced protection circuitry guards against overload, overheating and short circuits. Options include a rotary volume control, XLR and headphone-jack variants, and multiple amplifiers on a rack-mount tray. Pragmatic's Class-D digital amplifiers offer high efficiency and clock frequency, very linear gain and phase characteristics, a flat frequency response from 10 Hz to 50 kHz with no ripple in the passband, very low change in distortion versus output power (typically 0.01-0.05%), and very high signal-to-noise ratio and dynamic range.
