Rolls MS20C Splitter/Combiner/Isolator

The Rolls MS20c Splitter/Combiner/Isolator can be used to split a single balanced XLR input (or 3.5mm TRS input) into two balanced XLR outputs. It can also be used to combine two balanced XLR inputs into a single XLR output, or to simply isolate a balanced line for buzz or hum elimination. There is also a ground-lift switch for additional noise elimination. Note that when combining two condenser microphones, phantom power voltage is passed to only one of the microphones due to the internal isolation transformer.
