A simple selector with no change in sound quality. 4-channel mechanical selector selects the RCA and XLR signals and outputs them to the RCA and XLR terminals.
The hot and cold signals entered to an input XLR terminal(line 4,5) pass through the mechanical contacts of the selector and are led directly to the hot and cold output XLR terminals.The hot signal is also led to the output RCA terminal.
The signal entered to an input RCA terminals(line1,2,3) is led to the output RCA terminal and also hot terminal of output XLR terminals.
XLR outputs (HOT) and RCA outputs are directly connected bywires.
