MCS Filter Amplifier

Filter amplifiers FA with 8, 16, 32, 48, and 64 input channels and fixed gain, from Multi Channel Systems.

Amplifiers can be ordered with any gain and bandwidth configurations by the user's choice. For example, typical pass bands would be 1-300 Hz for recording field potentials and 300-3000 Hz for recording action potentials. It is also possible to use a broadband amplifier and filter the data with the digital filter of the MC_Rack software (see our Electrode Array Systems page).

MCS Programmable Gain Amplifier

Programmable Gain Amplifiers PGA with 16, 32, and 64 input channels, from Multi Channel Systems.

• The PGA is a filter amplifier like the FA above, but in addition, the gain can be flexibly adjusted from 10 to 5000 with the user-friendly FiltAmp software.
• Versions that feature two different pass bands are also available. Signals are split and the two pass bands are send to two separate output channels.
• Amplifiers can be ordered with any bandwidth configurations by the user's choice. For example, typical pass bands would be 1-300 Hz for recording field potentials and 300-3000 Hz for recording action potentials.
• It is also possible to use a broadband amplifier and filter the data with the digital filter of the MC_Rack software (see our Electrode Array Systems page).
