The Lynx-8 is an eight channel amplifier whose gain and both high and low pass filter values are controlled by either the Cheetah Data Acquisition software or the stand alone amplifier control program. A differential input port allows the amplifier to also subtract a reference value from the input signal prior to filtering or amplification. Lynx-8 amplifiers are intended for use with Neuralynx Analog acquisition systems and require power from the Lynx-8 Power Supply, sold separately.
