Having one or too problems in understanding the wiring for putting the amp in BTL mode [mono mode].
can anyone help?
heres the schematic 4 the chip
http://datasheets.maxim-ic.com/en/ds/MAX9709.pdf

just not sure about the dc input +-.
the datasheet says connect 'logic high to mono'?
and the board has two v+ inputs...and no v-
its confusing me

the amp:
