PA 200 is an installation amplifier that can work both in low impedance and with 70 / 100V line loudspeakers. It incorporates a switched power supply. The operating mode is selected by means of a switch on the rear panel and a switch block, which has some terminals reserved for future improvements. It incorporates an unbalanced LINE input and its own volume control, as well as 2 LEDs that mark the presence of a signal and if it exceeds the limit value. At the rear, the amplifier incorporates an RJ45 socket, which supports RS485 commands from an external device to control various functions of the amplifier.
