Product Description

650W Advanced and Efficient Power Amplification Wholesale Price Power Amplifier

The PA-650A is a high-performance mid-to-high power pure rear-stage broadcast amplifier, engineered to deliver robust audio performance for large-scale public address systems. Ideal for venues like shopping centers, industrial parks, and university campuses, this 650W amplifier balances substantial power output with precise sound reproduction, making it a reliable choice for both daily background music distribution and critical emergency paging.

Powered by a stable AC220V/50Hz input, the PA-650A delivers consistent 650W rated power, capable of driving 70V/100V constant-voltage speaker lines or 4-16Ω constant-resistance loads. This flexibility enables it to efficiently power extensive speaker networks across multi-zone spaces, ensuring uniform audio coverage even in complex layouts. Its frequency response of 80Hz–20kHz±1dB delivers rich, balanced sound across the entire audible spectrum, while a total harmonic distortion (THD) ≤0.1% guarantees minimal signal degradation, even at high volume levels. With a signal-to-noise ratio (SNR) ≥80dB, background interference is effectively eliminated, ensuring your audio remains clear and intelligible in busy environments.

Built for continuous, trouble-free operation, the PA-650A features a comprehensive protection circuit that guards against DC offset, overload, short circuits, and AC fuse failure, protecting both the amplifier and your 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 paging microphones, 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-650A provides the power, clarity, and durability to keep your PA system performing flawlessly.
