They are ideal partners for the NL820 Isolated Amplifier system. The filter settings have been selected for most electrophysiological protocols but other frequencies can be factory set to order. A rotary switch selects the 14 frequency settings giving repeatability over a wide range with 12dB/octave attenuation above the selected frequency value.

The ‘WB’ (wide-band) switch position by-passes the filter sections completely (both LP and Notch). The NL134-5-6 Four Channel Low Pass Filters active Notch filter provides rejection of line frequency interference when switched in. (No switch is fitted on the NL134).
