CA-30 Amplifier board / CA30 Board (PK-1500-A) ( 28 Transistor ) Code: 93524876

The CA30 professional power amplifier driver board features a CA30 Class H High Power Public Address Power Amplifier architecture, utilizing high-current multi-tier Class-H topologies and Surface Mounting Technology (SMD) for high-wattage pro-audio amplification.

Circuit Design & Architecture

• Topology:Multi-step Ca30 3000 Watts 3 Steps Class H Audio Professional Power Amplifier layout designed to switch rail voltages dynamically based on signal amplitude.
• Construction:Double-sided or multi-layer PCB utilizing automated SMD and through-hole mechanical insertion for structural consistency.
• Signal Handling:Low harmonic distortion design (THD < 0.01%) with flat frequency response spanning 20Hz to 20kHz.

Power Output & Load Specifications

• Stereo 8Ω:~1,500W to 1,700W per channel
• Stereo 4Ω / 2Ω:Stable down to 2Ω continuous long-term engineering operation
• Bridge Mode:Capable of high-output mono bridging into 4Ω/8Ω loads

Protection & Control Features

• Safeguards:Integrated circuitry paths for short-circuit, DC offset, thermal overload, VHF, and clip-limiter protection.
• On-Board Adjustments:Sensitivity selector pins/switches (commonly 0.775V / 1.0V / 1.4V), ground lift, and low-pass filter options.
