PHA series PA power amplifier
The PHA series amplifier are high-wattage PA power amplifiers that utilize Class-D switching power supply technology. This design offers minimal power consumption and high efficiency—up to 85%. As a result, these amplifiers help save rack installation space, produce less heat, and extend their operational lifespan. The PHA-1000S-2 and PHA-1500S-2 deliver rated output powers of 1000W, 1500W, and 2000W, making them ideal for digital public address systems at a low cost. They feature flexible speaker outputs, supporting both highimpedance (100V/70V) and low-impedance (4–8 Ohms) connections. This allows them to be used in both fixed PA installations and high-fidelity stereo sound systems. Each amplifier includes one balanced XLR input with a front-panel volume control. Visual status indicators—such as power, signal, and protection—are provided for easy monitoring. Comprehensive protection features are built in, including short circuit, overload, and over-temperature protection.
