Metering
Each individual input channel has its own 7-segment LED sum VU
ladder built in to that channel’s fader panel. This LED VU may be
internally programmed to monitor pre or post fader. It is always,
however, pre channel ON/OFF, allowing it to function as a signal
present indicator. The VU ladder is calibrated via a PCB-mounted
trimpot on the fader panel’s main printed circuit board (“CR1” – see
“FPI-80” load sheet on page 41 of the Technical Drawings, center left).
Note a single PEAK LED indicator at the bottom of the main module
faceplate also warns of overload transients (it monitors both pre and
post fader).
Input channels may also be metered at the console’s stereo SOLO
VU meter pair in the console overbridge, just above the VU/Oscillator
module. The SOLO meters may be driven pre or post fader, depending
on whether the module’s CUE (PFL) or SOLO (AFL) switches are
pressed.
