The A-M Systems 3600 Model 16-Channel Extracellular Amplifier is a dedicated instrument for extracellular electrophysiological recording, delivering 16 independent channels optimized for microvolt-level signal amplification in neural research. The system combines front-panel touchscreen control with USB-based Windows software command, supporting external TTL triggering for flexible experimental protocols. Built-in calibration and dual-channel oscilloscope monitoring enable real-time signal verification, while multi-unit networked control from a single PC accommodates large-scale recording arrays.
