AM-4000 Extracellular Amplifier

The AM-4000 is the perfect amplifier for high density recording. Amplifiers can be stacked (in 32 channel increments) for up to 256 channels of software controlled amplification using the Virtual Instrument Manager plugin in the DataWave SciWorks application.

The software control within SciWorks greatly improves your productivity by eliminating the need to fiddle with front panel knobs every time you need to make a change. Amplifier settings can be stored and recalled at any time for various experiments and easily adjusted at any time using the easy-to-use Virtual Instrument Manager interface.

See also the Multiplexed or Wireless High Density Recording System where the AM-4000 is integrated with high-density headstages for a high channel count recording solution.
