This stereo PA amplifier is specially designed for sound applications, e. g. in function rooms or clubs. It is able to operate in stereo mode, mono parallel mode or mono bridge mode.

Each of the two amplifier channels is equipped with a filter to be used as a high-pass filter or low-pass filter for a crossover network. With an additional STA-900A or STA-1500A, it is quite easy to set up a PA system with satellite speakers and a subwoofer. 

Extensive protective circuits are provided to protect the amplifier and the speakers connected. Two temperature-controlled fans will ensure sufficient cooling of the amplifier.
