The Palmer Pro PMS 02 is a 2-channel microphone splitter. These are used when a signal source has to be split into several inputs. For example, if the microphone signal has to be fed simultaneously to the hall mixer of the hall system, the monitor mixer on the stage, and - since the radio broadcasts the event - also to the OB truck. For this you need a microphone split box "1 in 3".
By using generously dimensioned low-frequency transformers, the sound remains unaffected, but ground loop humming is safely excluded. The PMS02 can also be used to convert from unbalanced to balanced and vice versa.
