Product Details


>Product Introduction

NS20 preamplifier is a voltage powered preamplifier with the characteristics of high input impedance, low background noise and wide frequency response range. It can be used with the 1/2-inch pre polarization measurement microphone of MP21. At the same time, it can also be compatible with other brands of measurement microphones, such as B&K, G.R.A.S. The output adopts a three wire plug, which can easily carry out power supply configuration and signal output. It is suitable for electroacoustic tester, multi-channel analyzer and other instruments.
