Our engineers have managed to increase the efficiency of the Class D board of the 140 Pro in order to get 10W extra power in stereo, and have been working hard in porting and adapting the dual-mono bridged mode from the 220 Pro and 250 Pro onto the 140 Pro, in order to deliver 210W in dual-mono with the same harmonic distorsion and signal-to-noise ratio than the 220 Pro and 250 Pro.
