Professional Audio · Professional Amplifier
Features
- 1U cabinet design, small in size and light in weight.
- Adopt the latest class D digital amplifier design, with low distortion and high efficiency.
- Adopt switched power supply technology, with high efficiency, to effectively suppress the harmonics of the power supply, meeting the EU green power supply standard.
- Adopt smart peak clipper to control the power module and speaker system to work in a safe range.
- Designed with standard XLR input interface and LINK output interface, convenient for different user needs.
- Support soft start to prevent absorbing large current from the power grid during startup and interfering with other electrical equipment.
- Smart control forced heat dissipation design, low fan noise and high heat dissipation efficiency.
- Support three optional modes: mono, stereo, bridge.
- Support overvoltage protection, undervoltage protection, overcurrent protection, DC protection, output short circuit protection, temperature control fan and so on.
