14.2.3
Aux Settings - SCA inputs
The Falcon XT can have two composite MPX outputs connected at the rear of the device (shown as MPX-1 and MPX-2),
as well as two broadband auxiliary inputs mixed with the former. The photo below helps understand how the multiplex
auxiliary signals are "mixed":
As you can see from the numbering shown, by flagging one of the functions from 1 to 4, the signal from the AUX (SCA)
input towards one or both of the two MPX outputs is added on. A typical case of use of adding onto the signal MPX
generated internally is the use of an external RDS encoder:
To be able to use the said external RDS encoder, connect a coaxial cable from it to one of the two AUX inputs on the
front panel.
Simply by convention
the AUX-2 is considered the external RDS input, therefore, after making the various
hardware connections, tick the checkbox for AUX 2 -> MPX 1.
It is also possible to apply (
solely to AUX-1
) a positive or negative gain, ranging from a
minimum of -20.0 dB to a maximum of +12.0 dB, with 0.1 dB steps. This could be useful
when the signal applied to 'AUX-1 is not the same as or of a similar level to that generated
by the Falcon XT processor during Network or Split mode (Split Circuit) operation.
14.2.4
Split Circuit:
The "
Aux 1 Split Mode by GPI 1
" (also known as MPX Splitting or Split Circuit) allows you to alter the Falcon XT
MPX-1
output by assigning it either an external MPX signal applied via the AUX-1
or
the MPX signal generated internally. This
feature is particularly useful when a broadcaster needs to create regional or local sub-networks of the main network at
any given time of the day.
A typical application case is when the type of advertising broadcast is changed over different geographical
areas, or a radio news programme is transmitted over different geographic regions with different
regionally-specific content.
Switching the two MPX lines between External and Internal is activated via an
impulse at Input Port 1 of the GPIN port.

By default, the Falcon XT is
NOT
configured in "Split" mode when supplied to
the customer, therefore the position of the switch is as shown in the figure on the
right, i.e. with the MPX generated internally.
