50/60Hz mains interference (line noise) is a perennial problem for electrophysiologists and can often be reduced using a range of grounding and equipment placement strategies. However, there are some situations where it cannot be removed or intermittently reappears during a critical recording.
Our powerful active noise elimination solutions can make mains interference a problem other people have! Reliable, easy to implement and now available for multi-channel recordings, our noise eliminators almost instantly remove 50/60Hz contamination, along with associated harmonics and complex noise.
Active noise elimination solutions, like our Hum Bug and D400 Noise Eliminators also have significant advantages over conventional notch filters, which degrade and distort the signal of interest. Find out more by reading our latest blog.
