The GM-D7400M, however, supports an improved harmonic distortion of 0.03% (versus 0.5%), a superior signal-to-noise ratio of 100dB (versus 92dB), and an enhanced load impedance capability of 2-8ohm (versus 1-8ohm). The GM-D7400M also includes a Pulse Width Modulator, a Low Pass Filter, a selectable 50Hz bass boost, built-in crossovers, and speaker level inputs. Despite its reduced power output, the Pioneer GM-D7400M is nonetheless cited as an extremely wise choice due to its affordable price and inclusion of extra features not found on the PRS-D1200M.
