The 2 channel power amplifiers are designed for commercial and industrial public address applications. With two separate amplifier in a single chassis and rated power ranges from 60W, 120W, 240W, 350W to 500W per channel which provides a wide selection to meet different size sound system needs. The amplifier is designed of rack mount type and T-2S60/ T-2S120 are in 2U height while T-2S240/T-2S350/T-2S500 are in 3U height. Both balanced and unbalanced line inputs for each channel make it selectable for installer, balanced line outputs for each channel feed to another power amplifier as well as secure the signal transmission is less noise and longer distance. 70V, 100V and 4-16ohm speaker outputs for each channel are convenient for installation when selection different speaker matching. Master volume controls for each control are included. Complete protection includes over heat, over load, clip & short circuit. Indications for power, signal, clip, protection and temp.
