than four (RM-2S4) or ten (RM-2S10) Sources, it will not be possible to select
unimplemented Sources.
When mains power is removed, the currently selected Source is stored in non-volatile
memory and recalled instantly once power is restored.
Auto-Selection of Inputs
As standard, the RM-2S4 has auto-selection of the inputs, i.e. whichever analogue or digital
signal is connected to the input will be used. There is also an option (in the serial settings)
for the RM-2S10 to have auto-selection of it’s separate ten analogue inputs in Bank ANA
and ten digital inputs in Bank DIG. For users with a smaller number of mixed analogue and
digital sources, the auto-selection allows the unit to switch automatically between the
analogue and digital banks according to what is connected.
For the RM-2S10, with auto-selection enabled, both the Bank ANA and Bank DIG LEDs are
illuminated (expansion banks can still be selected as normal, if fitted). If the current source
selection points to a valid digital input then the digital input will be selected. If it does not,
the similarly numbered analogue source will be used. If both are present then the digital
input takes precedence (hence auto-selection is only useful for a maximum of ten sources).
The analogue and digital presence indications are combined (ORed) and displayed
simultaneously.
Bank Selector
Pressing the Source selector knob inwards steps sequentially through all available input
Banks (groups of stereo inputs). Each press flashes the selected Bank LED and moves the
selected Bank onwards by one step. Once the last available Bank is selected, a further press
returns the selection to the first 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 reflected by the
Bank LEDs.
On the RM-2S4, BANK A corresponds to the four autoselecting (analogue or digital) stereo
inputs found on the rear panel, and further Banks become available with the addition of
optional expansion cards.
On the RM-2S10, separate Banks are provided for analogue (BANK ANA) and digital (BANK
DIG) sources – a total of twenty stereo sources may be attached if both Banks are fully
utilised. Further Banks become available with the addition of optional expansion cards. It is
not possible to select Banks which are not fitted.
When mains power is removed, the currently selected Bank is stored in non-volatile
memory and recalled instantly once power is restored.
To monitor SDI audio data, an RM-HD1 card has to be fitted. Each SDI signal carries 16
channels of embedded audio divided into four groups. To monitor this audio using an
RM-2S10 or RM-2S4 fitted with an RM-HD1 card, select each channel pair using the Source
and Bank controls as per the table below:
