4.10 Six-Way Splitter (93-100004)
4.10.1 Description
The wide range, low power, hybrid splitter/combiner provides the means to divide the signal
into six before the channel modules & re-combine the six signals into one after processing.
Being passive devices, the receivers should be maintenance free over their entire lifetime and
have an extremely high MTBF figure. It is not recommended that the top cover be removed
should the unit be suspected of failure, replacement with a new unit is usually the most cost
effective solution.

4.11 STPS12045TV 60A Dual Diode Assembly (94-100004)
4.11.1 Description
The purpose of these dual diode assemblies is to allow two (or more) DC voltage sources to
be combined, so that the main 24 volt DC rail within the equipment is sourced from either
the mains driven SMPU, or externally through an XLR connector on the rear panel. When
the DC is sourced externally, the heavy-duty diodes prevent any reverse current from flowing
back to their source or the alternative supply rail. Combining diodes such as these would also
be used if the equipment is to be powered from external back-up batteries.
