CROWN / CT4150 4-channel power amplifier

The ComTech DriveCore Series is a power amplifier that allows you to build a compact multi-channel system. With an ultra-lightweight, space-saving design weighing just 3.6 kg and a 1U size, it can be used to build a compact multi-channel system, such as in commercial facilities that use separate sound sources for different areas.

■ The ComTech DriveCore Series is a Class D amplifier incorporating AMCRON's latest DriveCore technology. The circuit design is based on five cutting-edge patents for feedback, modulation, and output stage technologies, seamlessly integrating the drive stage into an output stage the size of a dime (17.91mm). The front-end circuitry also achieves over 90% efficiency while maintaining the excellent acoustic characteristics of Class AB.
■ Without compromising performance, it delivers high-quality sound with a S/N ratio of over 110dB and a THD of less than 0.05% across all frequency bands.
■ The ComTech DriveCore Series also excels in energy efficiency. AMCRON is the first to introduce a universal power supply with three settings: Normal mode, which operates at full power at all times; Green mode, which minimizes power consumption when the input is below -40dBu and instantly outputs full power when the input signal exceeds this level; and DeepSleep mode, which reduces power consumption to less than 1W. Power efficiency is optimized to meet precise peak power requirements. Input signal routing is possible by switching the DIP switches on the rear panel.
