Inheriting the acclaimed industrial design of the DA Series, the CA Series delivers an elegant appearance, robust construction, and exceptional space efficiency. The compact 1U chassis allows maximum utilization of valuable rack space, while an optimized ventilation system provides superior heat dissipation for enhanced reliability and long-term performance.
1. Comply with CE, CCC and other regulatory requirements, and have good electro magnetic compatibility.
2. High conversion efficiency, green and environmental protection, energy saving and emission reduction.
3. PFC power factor correction circuit design, suitable for global working voltage.
4. High power, low distortion, excellent sound quality.
5. Stable work with 2 ohm load.
6. The output noise floor is low, the fan noise is low, and it will not cause interference when used in a quiet environment such as a conference room.
7. Small size, light weight, 1U height, easy to install.
8. Comprehensive protection circuit design, safe and reliable.
9. Stereo, parallel, bridge three working modes.
10. The gain can be selected (0.775V and 32dB).
11. XLR balanced input terminal, SPEAKON fourcore output terminal.
12. Clipping limiter: prevent the output clipping signal of the power amplifier.
13. Power amplifier output DC protection: prevent the output of infrasound signals.
14. The unique short-circuit protection mechanism provides uninterrupted sound output.
15. Temperature power control, over temperature protection.
16. Power supply undervoltage protection.
The whole new CA-450.4 digital power amplifier built in innovate power supply, modulation and control technology. It is breaking through the traditional technology and the overall performance has been substantially improved. Continuing the excellent industrial design of DA series digital power amplifiers, CA not only brings perfect appearance and structure but also has a compact 1U appearance which can make full use of the cabinet space and optimize the ventilation design to obtain better heat dissipation performance.
