TDT headstages are designed for use with TDT preamplifiers/digitizers. If you will be using a non-TDT amplifier, you will need to be familiar with your headstage specifications and ensure an appropriate power supply is provided to the headstage.

You can safely power TDT headstages using a voltage source of up to ±2.5V. The maximum range of the ZIF-Clip headstages is ~98% of the supply voltage. If you are using a headstage other than ZIF-Clip, see the section of the System 3 Manual for your headstage.

TDT headstages are typically available with two different styles of connectors: the DB26 for connecting to Z-series preamplifiers or the DB25 for connecting to the Medusa preamplifier. More information on these connectors is provided below.

The DB25 connector is primarily used to connect to TDT's Medusa preamplifiers. The information below includes the information you will need to connect to a non-TDT amplifier.
