MEA1060-BC Amplifier

For LTP experiments it is recommended to use a MEA1060-BC amplifier with blanking circuit BC.
A blanking signal (TTL pulse) transiently switches off the input stage of the amplifier during the
stimulus, thus avoiding the stimulus artifacts on non-stimulating electrodes. Amplifier saturation
is effectively prevented and the recovery time is greatly reduced. It is also possible to record from
stimulating electrode shortly after stimulation. To set up and connect the MEA1060 amplifiers,
please refer to the amplifier manuals.

Warning: If you want to use LTP-Director with a MEA1060-BC amplifier and a STG you need to
connect the TTL outputs in a different way than while working with MC_Rack and MC_Stimulus.
Please check your TTL connectors when switching between the two software packages.

Currently, the LTP-Director can control only voltage pulses. Please connect the MEA amplifier to
the +V or -V outputs of the STG (2000 series) for voltage stimuli. Using a STG of the 4000 series
you just have to connect it to the MEA amplifier.

The image schematically depicts the connectors of the MEA1060-BC amplifier. The shown
nomenclature will be used later in the text.
