Welcome to the MPA2I 2 Welcome to the MPA2I Miniature Preamplifier The 2-Channel Miniature Preamplifier MPA2I is connected to the microelectrodes for providing the initial tenfold amplification stage. It has additional common ground and reference electrode inputs. The reference electrode is ideally identical to the recording electrodes and placed into a comparable but inactive area or tissue.
2-Channel Miniature Preamplifier Manual 3 Setting Up and Connecting the MPA 3.1 General Setup Recommendations In the following, you find general recommendations for the installation. Important: It is important that the complete setup refers to a single common ground. The reference input has always to be connected. It is recommended to use a reference electrode. However, if you are not using a reference electrode, connect the reference input to ground (GND).
If you are not using a Faraday cage, it might be necessary to shield the complete setup with aluminum foil or similar to prevent electrical interference from the outside. Connect the aluminum foil to the ground of the setup (for example, the metal table). Troubleshooting: If you observe problems with noise, check that the ground of the setup is connected to exactly the same ground as the data acquisition computer.
2-Channel Miniature Preamplifier Manual 5 Pin Layout 5.1 Power Supply Supply voltage is applied to the output connector pins 8 and 15. The voltage source should supply a stable noise-free voltage. Do not exceed the maximum voltage. Pin 8: –3 V to –8 V Pin 15: +3 V to +8 V Warning: Do not mismatch the polarity of the power supply. A false connection may damage the unit. 5.2 5.
