High-Power 800W OEM ODM Amplifier Economical Broadcast Power Amplifier
PA-800A Pure Rear-Stage Broadcast Power Amplifier
The PA-800A is a high-power, professional pure rear-stage broadcast amplifier engineered to deliver robust, reliable audio performance for large-scale public address systems. Designed for demanding environments such as shopping malls, industrial facilities, university campuses, and transportation hubs, this 800W amplifier combines exceptional power output with precise sound reproduction to support both daily background music and critical emergency paging.
Powered by a stable AC220V/50Hz input, the PA-800A delivers a consistent 800W of rated power, capable of driving 70V/100V constant-voltage speaker lines or 4-16Ω constant-resistance loads. This flexibility makes it ideal for powering extensive speaker networks across large, multi-zone spaces. Its frequency response of 80Hz–20kHz±1dB ensures rich, balanced audio across the entire audible spectrum, while a total harmonic distortion (THD) of ≤0.1% guarantees minimal signal degradation, even at maximum volume. With a signal-to-noise ratio (SNR) ≥80dB, background interference is effectively eliminated, ensuring your audio remains clear and intelligible.
Built for continuous, trouble-free operation, the PA-800A features a comprehensive protection circuit that guards against DC offset, overload, short circuits, and AC fuse failure, protecting both the amplifier and connected speaker infrastructure. It performs reliably across a wide operating temperature range of -5°C to 80°C and 20%–80% relative humidity, making it suitable for installation in challenging indoor and semi-outdoor environments.
The 0dB AUX sensitivity ensures seamless integration with mixing amplifiers, pre-amplifiers, and other signal sources, simplifying system design. Its rugged, heat-dissipating metal chassis supports 24/7 operation, while its rack-mountable design optimizes equipment room space. Whether you need to power background music across a commercial complex or deliver critical safety announcements, the PA-800A provides the power, clarity, and durability to keep your PA system performing flawlessly.
