RA16BA

Medusa Base Station

Recommended for single or dual channel extracellular recordings and low channel count EEG’s, EMG’s and evoked potential recordings (such as ABRs), the Medusa Base Station is a versatile signal processor designed to acquire, filter, and process data digitized on one of our preamplifiers. PCM analog outputs can be used for a wide variety of signal production tasks, including control of motors, electrical stimulation, and monitoring analog signals during acquisition. See our monitor speaker and our patch panel for easier access to output channels. For multi-channel neurophysiology and higher channel count EEG, consider the RZ5 or RZ2 base stations.
