Acute Headstages

RA16AC & RA16AC4
Connect this headstage directly to NeuroNexus acute 16-channel electrodes or use it with metal microelectrodes via a 0.5 mm adapter. This small form factor is also available with 4x gain.

This headstage is designed for the 64 and 32-channel acute NeuroNexus probes. Its miniature electronics occupy the same small footprint as our 16-channel acute headstages.

The four channel acute headstages use a low-profile connector for a slim form factor and are available with a unity or 4x gain. This economical 6-pin design provides easy connection to metal microelectrodes for lower channel count systems. The RA4AC1/RA4AC4 is also provided with a 6-pin male connector with flying leads.

Note: The RA16AC, RA16AC4, NN64AC and NN32AC are available in ZIF-Clip compatible versions.
