Chapter 7: VEA-6840 Video Equalizing Amplifier Module Installation
60 6800/7000 Series - Distribution and Routing Products Installation and Operation Manual
Installation
The VEA-6840 module can be installed in any of the Leitch FR-6800
series video equalizing amplifier frames.
Termination of unused outputs are not required; however, a perfect
response can be obtained if unused outputs are terminated.
Removing and Installing the RMV Submodule
The VEA-6840-RMV has a Removable Gain/EQ submodule installed
that contains the R5 Gain Adjustment potentiometer and the R6 EQ
Adjustment potentiometer. This submodule provides a quick
card-to-card transfer of preset Gain and EQ in the event of DA card
failure or swap-out.
The RMV submodule is removed by gently pulling straight up on the
submodule card, and then “unplugging” it from the DA card. The RMV
can be installed onto the new card by plugging it into the same position
on the card as before. There is no need to readjust the EQ or Gain because
the RMV submodule retains the adjustment from card to card.
