Headstages for Model 3600 16-Channel Amplifier


16-Channel Stimulating & Recording Headstage

For simultaneous stimulation and recording on any combination (or all) of the 16 channels when paired with our Model 3600 Amplifier. Capped in the Omnetics Corporation nanominiature connectors, we can provide adapters for use with other electrode configurations, including the Michigan Probe. This headstage uses fast switching relays (microsecond switching times, not milliseconds!) to control signal paths between stimulating and recording modes.

Includes built-in recording output cable. Optional Stimulation control cable (#962050) is required to operate stimulation functions. Max current is 20 mA, with a ±10V voltage range.




16-Channel Record-Only Headstage

Microminiature x20 headstage with 16 amplified channels and an amplified reference electrode channel. The entire headstage is roughly the size of a penny, and features 0.025" connector spacing using Omnetics Corporation nanominiature connectors.

Does not include a recording output cable. Order #961150 Output Cable.

Input options include direct connections to electrodes or to a connector with small input leads (Product 96



Model 3600 Control Software

The Model 3600 is supplied with optional Windows control software. This software controls all features of the amplifier via a USB port (cable included).

The program also enables the storage of an unlimited number of 16-Channel parameter files, as well as provides a real-time notepad that logs changes in parameter settings or experimenter-added notations.


根据需求,还可以选择MODEL 4000来记录更多通道:


Stuck at 2 channels, when you want to record more then 30? Or perhaps you want to record up to 217 Channels from an awake behaving animal, but can't afford the design, engineering, and production of a custom commutator to allow it?

Now you can record what you want as much as you want! With the new MultiRecord System!


Utilize a simple commutator to record high channel counts:

31 Channels over a 3-line commutator

62 channels over a 4 line commutator

124 channels over a 6-line commutator
