Model 3300 Audio Monitor
A-M Systems


The Model 3300 Audio Monitor is a high-quality audio amplifier designed to transform electrophysiological signals into sounds.

This amplifier features a built-in 6-band audio equalizer that enables the user to tailor the audio performance to their personal satisfaction, a high-fidelity quality speaker, a dedicated notch filter designed to minimize noise interference generated by power lines, a headphone jack, and an BNC line out jack that enables the the Model 3300 to be used as another signal amplifier prior to subsequent processing by other instruments.

The instrument can be placed on a lab bench with its built-in metal stand, or it can be mounted in any industry standard equipment rack (with included rack-mounting hardware). In addition, the instrument is shipped with it's own desktop power supply.
