Multi-channel Filter/Amplifiers

Ideal for conditioning signals for bandwidth and level before data capture. The range extends from flagship, high versatility VBF 40 systems suited to multi-role test environments, to semi-custom solutions which can be factory-configured with the appropriate range of gain, frequency response, transducer support and other features. Tens of thousands of channels of our multi-channel filters have been installed over the last three decades, many of them still in daily use.
