This is a Class D digital amplifier tailored for commercial and industrial public address applications. It features a 1U rack-mount design and delivers a rated output power of 4×60W.
Each of the four channels supports both balanced and unbalanced line inputs, allowing for versatile system integration. Balanced line outputs enable daisy-chaining to additional amplifiers while ensuring reduced noise and reliable long-distance signal transmission. The amplifier provides 70V and 100V speaker output options, simplifying installation across various speaker configurations.
Built-in protection mechanisms guard against clipping, short circuits, overheating, and overload conditions. The front panel includes clear LED indicators for power, signal presence, clipping, protection status, and temperature monitoring.
