sources can be selected. The terms: Tuner, Cinch, Ext1 and Ext2 are used for describing purposes only, technically
all four inputs are equal (except for the fact that tuner left (TUNL, pin 6) is also selectable by Normal Select).
With bit NSS set LOW a selection can be made between the four stereo line inputs (like the hi-fi input select). With
bit NSS set HIGH, bits NSH and NSL make a selection between four special select functions.
When a stereo input source is selected, both channels are added to obtain a mono output signal, then the output
signal at LINOUT is equal to:
In the Volume mode the output signal is equal to:
Note that for the Volume mode the hi-fi input select (ISH and ISL) determines the used input source.
