PA50 Measurement Power Amplifier
PA50 is 2th generation of class AB audio power amplifier designed by BSWA TECH. It is a high performance, 50W audio power amplifier for sound, vibration and general purpose applications that replaced the previous generation product.
PA50 redesign the case and power amplifier circuit to reduce the output noise and enhanced the operational stability. When adjust the gain to the maximum, the A-weighting output noise is only 58uVRMS.Thanks to the class-AB amplifier technology, it has excellent THD+N performance and is ideal for high-precision measurement that requires low distortion.
