Main Meters
The main meters are quad 26-segment,
multicoloured LED bargraphs, displaying the
four Sources in the currently selected Bank.
The meters behave as “input” meters, i.e. they
are not affected by front panel signal Modifiers
such as Side or Cut.
Several different characteristics are available
for the meters to suit different applications
and regional preferences. The active meter
characteristic is selected by
the settings of DIPSwitches 8, 9 and 10 on DIPSwitch Block 1 (found on the underside of the
unit), according to the following table.
Fig 2-6: RM-4C8 DIPSwitch Settings
Note that power should be removed from the unit while making changes to the
configuration switches and reapplied once the changes are complete.
