PA Series
The PA Series amplifiers are professionally developed for high-end entertainment applications, including party rooms, bars, and KTV venues. Available in both two-channel and four-channel configurations, these amplifiers incorporate thoughtful design considerations for their operational environments and user interaction. The front panel is equipped with per-channel level indicators for more accurate and intuitive monitoring of the amplifier's operational status, facilitating the assessment of signal strength to the load and enabling more effective integration within the entire audio system. A humanized aesthetic design enhances the user experience.
Key Features & Design
-
Dual Bridge Design & Independent Power Supply: The PA Series utilizes a dual-bridge design with independent channel power supplies to achieve the ideal performance expected by most users. This design offers an optimal balance in terms of weight and dimensions.
-
Cooling & Protection: The amplifiers are configured with channel cooling heat sinks, variable-speed DC fans, and comprehensive protection circuits. These features ensure high efficiency and reliability even under demanding load and power supply conditions.
-
Advanced Circuit Architecture: The Class-H circuit achieves an operational efficiency of up to 92%, enabling it to effortlessly drive loads from 8Ω to 4Ω. Its unique design ensures power transistors operate within a safe zone, approaching Hi-Fi grade circuit fidelity.
-
Intelligent Power Management (Power Smart Constant Technology): When the connected load impedance falls below the rated range, the output power is intelligently controlled and prevented from increasing further, stabilizing within a safe and reliable operating range. This significantly enhances the amplifier's stability.
-
Resonant Soft-Switching Technology: Specifically designed for high-quality, high-demand professional amplifiers, this technology—also known as Zero-Voltage Switching (ZVS) On/Off—eliminates the current surge (di/dt) typical of conventional power switching.
-
Aesthetic Design: The amplifier features a unique and refreshing appearance. The entire front structure forms a three-dimensional shape, creating a strong visual impact and a sense of dynamism.
Comprehensive Protection Suite
The amplifier incorporates a full suite of protection circuits for enhanced safety and durability:
DC output protection, overload protection, short circuit protection, over-temperature protection, input limiter protection, soft-start protection, current fuse protection, and transformer over-temperature protection. These utilize sensitive and fast IC-based protection circuits.
Product Advantages
-
Premium Output Transistors: Utilizes specially selected and matched high-end output transistor pairs, resulting in excellent dynamic response, refined sonic character, and high-fidelity audio reproduction.
-
Advanced Thermal Management: Incorporates innovative automatic temperature compensation and constant-temperature technology. The circuit intelligently detects and regulates the operating temperature, ensuring the amplifier remains within a safe range under various environmental conditions.
-
High-Efficiency Cooling System: Features high-density heat sinks, comparable to those used in aerospace applications, paired with a proprietary intelligent temperature regulation circuit. This combination effectively minimizes the operating temperature, guaranteeing high stability.
-
High-Quality Components: The internal circuitry uses imported, low-noise components with high sound reproduction accuracy. High-precision resistors and capacitors ensure detailed performance and minimize zero drift.
