Ampli CROWN CTs4200A là cục đẩy công suất của thương hiệu JBL được nhập khẩu và phân phối chính hãng bởi jblvietnam.vn tại Việt Nam
The Crown-Audio CTs 4200 is a 4-channel power amplifier housed in a 2RU rack, offering 190 watts per channel at 8 ohms, designed for fixed installation use.
This amplifier features multiple simultaneous channel operation modes, 70 volt and 100 volt support, a switching power supply, and a variable speed fan cooling system. There is a comprehensive set of front panel indicators for each channel, along with advanced, well-designed thermal protection and fault isolation circuitry. The rear panel offers individual channel level trim controls, and 4-position operating mode switches.
The CTs 4200 offers a progressive design and advanced features for a moderate price per channel, and represents a viable solution for budget-conscious commercial, theatrical, educational, and houses of worship installations.
