Auto-Selection of Inputs
As standard, the RM-4C8 has auto-selection of the inputs, i.e. whichever analogue or digital
signal is connected to the input will be used.
Bank Selector
Pressing the left-hand Source selector knob inwards steps sequentially through all
available input Banks (groups of four inputs). Each press moves the selected Bank onwards
by one step; once the last available Bank is selected, a further press returns the selection
to the rst available Bank. The currently selected Bank is indicated by illumination of the
corresponding Bank LED. The currently selected Bank may also be changed via the remote
control ports (see the appropriate sections of this manual), and such changes will also be
reected by the Bank LEDs.
As standard, the RM-4C8 possesses two Banks, A and B. Both comprise four monophonic
Sources, each of which may be a mono analogue signal, part of a stereo analogue signal,
part of a stereo AES/EBU digital signal or any combination thereof. Attaching a valid AES/
EBU digital signal automatically assigns its two channels to a pair of Sources. Further Banks
become available with the addition of optional expansion cards. It is not possible to select
Banks which are not tted.
When mains power is removed, the currently selected Bank is stored in non-volatile
memory and recalled instantly once power is restored.
Main Meters
Fig 2-5: RM-4C8 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 aected by front panel signal
Modiers such as Middle+Side or Cut.
Several dierent characteristics are available for the meters to suit dierent 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.
