This series of amplifiers are specially designed for commercial audio applications with high quality sound reinforcement and optimized design, featuring high quality sound, high stability, large dynamics, low noise and high energy efficiency. The whole series features fanless and silent design without any mechanical noise, which is suitable for all kinds of application requiring Iow noise. With the newly developed DSP audio signal processing system, it can ensures providing high quality sound at any volume. The amplifier's EQ is optimized for use with the FIT Series of high-quality commercial loudspeakers. Using them together will improve the audio experience. Amplifier output can be selected to support stereo or mono mode, support for low impedance (4Ω,8Ω) and high impedance (100V, 70V) output, flexible matching a variety of types of high-quality commercial speakers. The advantages of this amplifier allow it to be widely used in various types of stores, restaurants, bars, conference centers, schools, supermarkets, showrooms, shopping malls, hotels and other occasions where excellent sound quality is required.
