Three Sets Source Selector (Active)




UC1913A


Three Sets Source Selector (Active)

UC1913A module is designed to select and play one of three audio sources from other CSP Transceivers or Receivers. There are three pushbuttons on the front panel, each corresponding to the three signal pairs A, B, C. When one of the three buttons is selected, the corresponding audio signal displayed on the output, and only one audio source could be selected. If the selected button is pushed again, the output is turned off. The corresponding LED to each button shows which source is selected. If the supplied power is loss, UC1913A stores the last source selected.
 
There is an additional RJ-45 jack on the back panel, to connect with other CSP receiver modules, so all three audio pairs A,B,C and power pair D could pass through both RJ-45 jacks. And the system allows the chain connection up to 10 receiver modules.

UC1913A module could be powered from a 24VDC power supply by using the rear panel terminal block, and the power also could be provided to all the connected modules by Pair D of UTP CAT5 cable.
