The Powersoft M28Q is a 4-Channel power amplifier with 700 watts at 4 ohms from each of four channels with bridgeable pairs: a single M28Q is good for powering a complete little bi-amped stereo system, a 3-way mono stack of decent size, a variety of floor monitors, or even a comprehensive PA system with multiple 70V lines. All at a quality level as can be expected from Powersoft. Optimized for 4 ohm loads, the M28Q is a fantastic value practically as well as commercially.
