Headstages – Low Impedance
TDT’s low impedance headstages connect directly to our Medusa preamplifiers via a standard 25-pin connector. The RA4LI is a four-channel version, with standard 1.5 mm safety connectors for easy, direct connection to electrodes. Ideal for EEG, the RA16LI includes sixteen channels and can be used with the LI-CONN for connection to electrodes. Both versions include a built-in impedance tester for each channel and the reference.
The RA16LI-D is a 16-channel low impedance headstage, providing differential inputs for each channel, improving common mode rejection on all channels and making it ideal for EMG recordings. The headstage uses a DB44 input connector.
