Preamplifier Type 2671 is very compact and operates over a wide range of temperature, humidity and other environmental conditions. It has a very high input impedance, presenting virtually no load to the microphone. The low output impedance means that you can connect long cables between the preamplifier and measurement equipment.
The main application for the preamplifier is in vibration setups with DeltaTron or ICP input modules where it is also desired to make acoustical measurements. It presents a very price-competitive solution compared to a system with both vibration and acoustical inputs.
