Extracellular recording with 4-channel tetrodes becomes more and more popular. The EXT-T2 amplifier/filter is designed for recording from up to two tetrodes. The signals recorded from every single tetrode attached to the headstages are amplified and filtered, and linked to the BNC connectors at the front panel. Every OUTPUT is available at two BNC connectors. Measurements are done in single-ended configuration against GND, and filters and gain factors can be set internally.
NEW: Tetrode amplifiers are also available with miniature headstages for in vivo experiments in freely moving animals.
