The Wangine WPA-120 is a stereo power amplifier designed for high-fidelity audio applications. Manufactured in Taiwan, the WPA-120 features a silver exterior and is built with a robust design that includes a dual-mono configuration for enhanced sound quality. It has a maximum power consumption of 800 watts and measures 422mm in width, 140mm in height, and 318mm in depth, weighing approximately 16.3 kg. The amplifier delivers a continuous output power of 2x120W at 8 Ohm, with a dynamic output power of 2x240W at the same impedance. Its performance specifications include a total harmonic distortion (THD) of less than 0.015% and intermodulation distortion (IMD) of less than 0.009% at rated output. The damping factor is rated at 200 at 1 kHz, and the signal-to-noise ratio is an impressive 110 dB (IHF, A-weighted). The frequency response spans from 5Hz to 200,000Hz (+0, -3 dB), allowing for a wide range of audio reproduction. The amplifier supports speaker outputs from 4 to 16 Ohms, with an input sensitivity of 1 Volt and an input impedance of 50 kOhm. It features a spectrum analyzer with various frequency bands for detailed audio analysis and incorporates multiple protection circuits, including a switch-on delay to prevent speaker damage. This unit is suitable for audiophiles seeking quality sound reinforcement for various audio environments.
