PZ3 Z-Series Preamplifier

The PZ3 is an integrated preamplifier and headstage designed for high channel count recordings from low impedance electrodes. It is well suited for ECOG, Evoked Potentials, EEG, LFP, EMG, and other similar recording applications.

Used exclusively with Z-Series base stations, preamps are available in 32, 64, and 128 channel models. The PZ3 amplifier offers shared or true differential operation, low input inferred noise, impedance checking, and an optional high input range mode.
