I need help
there is an amplifier kit schematic diagram but i dont know how to connect the audio directly to the board(the switches were not included apparently)

The audio signal input looks like it's the "1" under "VOLUME".
Audio ground doesn't seem to be shown, it's probably the "3" under "VOLUME".
.  That took much longer than I thought it would.

I'd say it's missing from the diagram. At first I had the same thought, the audio goes to the leftmost MON switch but from there it only goes to the LINE OUT.
And don't forget it is pretending to be stereo...

And me. The 4 rightmost switches seem to have small hard to see connections to the MON's "looped around" connection.

It sure would be nice if they'd provide a proper schematic, I hate these drawings that show wires connecting to pins on drawings of actual components, it's very difficult to follow where anything goes, especially if you don't have exactly the same components.

Looks like only one channel is shown connected to the board via what are obviously two-gang pots. You're presumably supposed to intuit the other channel.

An actual picture of the board would be revealing on that subject, if there're connections for both channels. Or perhaps there are two copies of the board, one for each channel?
