The audio circuitry lives alone in one chassis, suspended on MOON's M-Octave damping system; the power supply, digital controller, software and display occupy the other. Inside, each integrated circuit in the signal path has its own inductor in the power supply regulation, 40 stages in all (MOON calls it i2DCf), and the gain stage is fully balanced from input to output. Three balanced and five single-ended inputs each have ±10 dB gain offset and can be set to bypass the volume control for home theater.
