System 3
PZ2 PreAmp
*Note: When sampling at a rate of 48.828 kHz the PZ2 preamplifier is limited to a
maximum of 128 channels.
**Note: If longer cable lengths are required, contact TDT.
Input
Connectors
PZ2 Preamplifiers have up to 16, 26-pin headstage connectors on the back of the
unit. A1 – A16 represent the 16 channels coming from each connected headstage.
The PZ2 channels are marked next to the respective connector on the preamplifier.
So, for the connector for channel 1 – 16, A1 is channel 1 while on the connector
for channels 17 – 32, A1 is channel 17.
Important!
Each input connector uses its own unique ground and reference. When using multiple
headstages, ground pins on all headstages should be connected together to form a
single common ground. See “Headstage Connection Guide” on page 6-99.
