(NL104A) AC Preamplifier

Product Summary

The NL-104A AC Preamplifier is a low noise, high input impedance, differential, preamplifier. It can be used alone for making recordings from low resistance (gross) electrodes, or with the NL-100AK headstage for microelectrode recordings.

 

  • A low noise, high input impedance, differential pre-amplifier
  • Can be used alone for making recordings from low resistance electrodes
  • Or used with the NL100AK headstage for microelectrode recordings

The NL-104A features a wide dynamic balance adjustment for asymmetrical inputs (useful for balancing interference and shock artifacts), a choice of two input time constants, 8 gain ranges and 3 high frequency filter settings. An internal 50 Hz oscillator is provided for precisely balancing the input (input switch in the CM position).
