High Density Tethered Multiplexed System
Looking to record a large number of channels?   DataWave offers a cost effective solution with the Tethered Multiplexed System.
At the heart of the high density Tethered Multiplexed Systems are the TBSI multiplexed headstages.   These headstages give you the ability to acquire a large number of channels with a minimal number of output wires, resulting in simplified connections, easier mobility of the animal and lower overall hardware costs.

The multiplexed systems reduce the number of wires in the cable between the animal and the amplifier as seen in the table.

The Tethered Multiplexed System combines the TBSI multiplexed headstage, AM-4000 Amplifier, DataWave data acquisition hardware and the DataWave SciWorks Experimenter for a superior high density recording solution.   A Dragonfly Commutator can also be added to improve animal mobility.

* If a reference channel is used with the Multiplexed Headstage then the actual channel count will be one less than what is listed.
High Density Tethered Multiplexed Systems
- 31, 61, 93 and 124 channel options
- Minimal wires between animal and amplifier, 31 (3 wires), 62 (4 wires), 93 (5 wire) and 124 (6 wires)
- Simplifies and lowers the cost of an optional commutator by minimizing the number of connections
- Perfect for freely-moving animals and behavioral experiments
- Incremental system growth in 32 channel increments
- Optional LEDs for video tracking
- See AM-4000 Amplifier for additional amplifier information
