Amplifier

The MED64 Amplifiers feature broad acquisition bandwidth that allows you to record several different types of signals. Thanks to the MED Probe’s lowest-impedance electrodes, excellent signal-to- noise ratio can be achieved even with the broad acquisition bandwidth.

The main amplifier has built-in analog high/low cut filter, that enables 1 set of MED64 System to be shared for multiple purposes. The same amplifiers are used for all MED64 Systems and upgrades can be made with minimum cost.
