The Model 1700 Differential AC Amplifier is intended for research or teaching applications requiring extracellular neurophysiological recording from excitable tissue, such as nerve or muscle, and is camplable of making EMG, EEG, EKG, and ERG recordings.

The Model 1700 contains 4 independent amplifiers plus a power supply in a single enclosure enabling several channels to be recorded simultaneously. Also, combining four amplifiers in a single instrument reduces the construction cost and these savings are passed on to you.

Each amplifier contains a high-gain, low-noise differential stage followed by low-frequency, high frequency, and notch filters. A connection is also provided for a stimulator input so that recording or stimulating through an electrode is possible.
