Product Description
120W Advanced and Efficient Power Amplification Circuit Power Amplifier
The PA-120A is a high-performance, professional-grade pure rear-stage broadcast power amplifier engineered to deliver reliable, high-fidelity audio for public address (PA) systems. Designed for seamless integration into commercial, educational, and hospitality environments, this 120W amplifier combines robust construction with precise audio performance to meet the demands of daily public broadcasting, background music, and emergency paging applications.
Powered by a stable AC220V/50Hz input, the PA-120A delivers consistent 120W rated power to drive 70V/100V constant-voltage speaker lines or 4-16Ω constant-resistance loads, making it ideal for medium-sized spaces such as school campuses, retail stores, and office buildings. Its frequency response of 80Hz-20kHz±1dB ensures clear, balanced audio reproduction, with THD ≤0.1% guaranteeing minimal distortion even at full volume. A signal-to-noise ratio (SNR) ≥80dB further eliminates background interference, ensuring your message or music is heard with exceptional clarity.
Built for long-term reliability, the PA-120A features a comprehensive protection circuit that guards against DC offset, overload, short circuits, and AC fuse failure, preventing damage to both the amplifier and connected speakers. It operates reliably across a wide temperature range of -5°C to 80°C and 20%-80% relative humidity, making it suitable for installation in varied environmental conditions.
The PA-120A’s 0dB AUX sensitivity ensures seamless compatibility with mixing amplifiers, pre-amplifiers, and other signal sources, simplifying system integration. Its rugged, heat-dissipating chassis ensures continuous operation, while its compact, rack-mountable design saves valuable space in equipment rooms. Whether for daily background music or critical emergency announcements, the PA-120A delivers the power, clarity, and durability needed to keep your PA system running flawlessly.
