The JTS CS-4 is a professional 4-channel automatic microphone mixer designed to simplify and optimise multi-microphone sound reinforcement systems. Engineered for fixed installations and scalable configurations, the CS-4 automatically manages microphone levels to deliver clear, consistent speech without the need for constant manual adjustment. It is ideally suited to corporate boardrooms, conference rooms, government buildings, houses of worship, and educational facilities.
Part of the highly flexible JTS CS Series, the CS-4 can be daisy-chained with an unlimited number of additional units, allowing system designers to build installations of virtually any size while maintaining reliable and intelligible audio performance.
Housed in a compact and robust metal enclosure, the CS-4 is designed for professional rack or desktop installation where reliability and long-term operation are essential. Each channel features individual gain control and switchable phantom power, ensuring compatibility with a wide range of condenser and dynamic microphones. Balanced XLR inputs and outputs provide clean, low-noise signal integrity throughout the system.
The intuitive front-panel layout allows installers and operators to configure the unit quickly, while rear-panel connectivity supports system expansion and external device control, such as speaker switching or camera triggering.
