• YG 18A
YG 18A is the active version of YG 18.Thanks to the highly powerful multi-channels D class switching power amplifier module (1 X 1000W@4Ω + 2 X 2500W@4Ω), one active YG 18A can drive maximum 4 pieces passive YG 65 line array speakers. The amplifier module is developed by exceptional analog circuit technology which is without unwanted DSP treatment. It delivers widely open and crystal clear sound. The built-in analog crossover and limiter make the system well-protected and truly plug and play.
