Medusa4Z Bioamp - TDT Medusa4Z User Manual

Medusa4Z BioAmp

Biological signals from the subject are input to the Medusa4Z for amplification and
digitization. The Medusa4Z transfers digitized data to the RZ6 processor via a fiber optic cable.
The fiber optic connection electrically isolates the Medusa4Z from the RZ6 and ensures that
no additional noise is introduced to the biologic signal. This design is intended to be used with
the preamplifier running on battery power alone, placed inside the Faraday cage with only the
fiber optic cable connecting it to the RZ6.
Max Input: ± 10 milliVolts max input.
Gain: The Medusa4Z amplifies the signal by 100x before digitizing and transferring it to the
RZ6. The RZ6 automatically accounts for this 100x gain when receiving the data, yielding a net
unity gain.
Power: The Medusa4Z is powered by a Lithium-ion battery. It can be charged in 4-6 hours and
will power the amplifier for up to 30+ hours when using a single active channel.
Important
The supplied battery charger must NOT be connected or inside the enclosure when running experiments. To
protect the battery, do not leave the Medusa4Z on the charger for an extended period of time (1+ week).
By default the Medusa4Z will boot up as shown above. A few changes must be made to the
default settings to use for ABRs.
