VEA-684 works in FR-680 series video distribution amplifier frames. Due to
the cable type and optional removable gain and EQ setting, the following
modules are available.:
Installation
VEA-684 video equalizing amplifier modules can be installed in these frames:
• FR-683 – 4 video DA modules mounting frame
• FR-684 – 10 video DA modules mounting frame
• FR-684AV – 5 video and 5 audio DA modules mounting frame
There is no need to terminate unused outputs, but a perfect response can be
obtained if unused outputs are terminated.
