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.

Features

• Broad acquisition bandwidth of 0.1 Hz -10 kHz.
• Low-cut filter (High-pass filter) with 0.1, 1, 10, and 100 Hz cutoff.
• High-cut filter (Low-pass filter) with 1, 2.0, 2.5, 7.5, and 10 kHz cutoff.
• Built-in 2 channel amplifier.
• Built-in digitizer.
• 64ch × 1 and 16ch × 4 input terminals allowing connection to all types of connectors.
• USB connection to computer.
