Headstage Pre-amplifiers
Small, low weight pre-amplifiers with high resolution. Low noise, low power and low input bias from 8 to 72 channels.
QuickClip® Headstages
QuickClip Headstage Pre-amplifiers magnetically self-align and connect to EIB for less stress on animal and researcher. Higher cycle count, lower profile.| Photo | Name | Channels | References | Differential Stim Lines | Grounds | Mass | Video Tracking LEDs | Input Connector | Output Connector | Tether |
