5 Connecting FlexMEAs
FlexMEA36, plastic spacer and adapter (ADPT-FM-32) connected to a 32-channel miniature
amplifier MPA32I.
The side with no screws is considered the top side of the MPA32I. If the adapter is oriented
as shown in the figure, the FlexMEA36 is inserted with the contact pads facing downward.
For connecting the FlexMEA72 you need the adapter ADPT-FM-72. Please see the datasheet
FlexMEA72 in the Appendix.
Connecting the FlexMEA36
 The FlexMEA adapter has a drawer for inserting the FlexMEA36. Open the slot of the white
drawer. Grip the sides of the white slot cover with your fingers and carefully pull open the slot
cover only a little bit (about 1 or 2 mm). Do not demount the cover as the plastic supports might
break easily.
 Insert the FlexMEA36 into the slot of the drawer, with the contact pads upside down .Insert the
plastic spacer into the slot of the drawer.
Important: Please use a thin plastic spacer between the FlexMEA36 and the connector so that the
contact pads make a tight contact to the connector pins. Otherwise, the FlexMEA36 will sit too
loose and will have a bad contact resulting in a higher noise level. The spacer should be placed
on the opposite side of the contact pads of the FlexMEA36 in the drawer.
 Carefully push back the slot cover of the white drawer until it locks.
