Double-clicking the macro in RPvdsEx displays the macro properties and allows users
to easily configure the macro. Additional information on using the macro is available
in the macro properties dialog box.
This macro is not required for preamplifier operation but is recommended if the user
requires more control over the amplifier power/up or power/down status or front
panel LEDs. See the relevant sections below for more information about these
features.
PZ2 Features
Clip Warnings and Activity Display
256 front panel LEDs can be used to indicate spike activity and/or clip warning
depending on display mode and configuration. See “Display Button” and “Status
LED” below for more information.
Recording Channel LEDs
When enabled, LEDs for each channel may be lit green to indicate activity or red to
indicate a clip warning.
Green: Activity | Red: Clip Warning
Clip Warning When the input to a channel is greater than -3dB from the
preamplifier's maximum voltage input the LED for the
corresponding channel is lit red indicating clipping may occur.
Activity Whenever a unit (spike) occurs (the sensitivity threshold can
be configured with the PZ2_Control macro) the LED for the
corresponding channel is lit green.
Note: The LED Indicators are also mirrored on the RZ2 LCD display.
