Descriptions This range of power amplifiers are designed for general commercial and industrial public address applications. Rack mount design in 2U type, rated power ranges from 60W, 120W to 240W which provides a wide selection to meet different size sound system needs. Both balanced and unbalanced line inputs make it selectable for installer, balanced line output feeds to another power amplifier as well as secures the signal transmission is less noise and longer distance. 70V, 100V and 4-16ohm speaker outputs are convenient for installation when selection different speaker matching. A master volume control is included. Complete protection includes clip, short circuit, high temp and overload. Indications for power, signal, clip, protection and temp. Features Rack mount amplifier in 2U type Rated power from 60W, 120W to 240W 70V, 100V and 4-16ohm speaker outputs Isolated transformer for human safety operation Balanced XLR type line input and unbalanced 1/4 inch TRS phone jack line input Balanced XLR type line output feeds to another power amplifier Reliable protection of over heat, over load, clip & short circuit. Indications for power, signal, clip, protection and temp Excellent device of radiator cooling fanner that ensures working effectively. GND/lift switch to have two options: earth line grounded or lifted Optional DC 24V input Panel with/without handhold Faults monitoring module, it can output short circuit signal to achieve main/spare amplifier switch.
