None of the values shown is especially critical and it does not

matter which channel output you connect to. The in-line connector or

clip is to allow disconnecting the Old Apple Sound wire when you wish to

remove the Stereo Board for cleaning, etc.. It can be just a place where

the wires are twisted together and covered with tubing which fits

snugly.

A handy place to connect the pot leads is on the Speaker connector

at the right front corner of the motherboard. You can tac on wires near

the bottom of the pins to leave room for reconnecting the Speaker plug.

Note: As you face the front, the Left pin is +. It does not matter which

outside leads of the pot go to which pins unless you care about having a

clockwise turn = more volume. Otherwise, just connect the end leads and

set the pot for the output level you like.

If your Stereo Board has outputs which can drive speakers and you

want to connect plain (unamplified) speakers to the board, the above

connection will not do the job. If you do not mind poking around on your

Stereo Board, you can probably find a couple of mini pots which set

output volume for each channel. (I do not know if the SuperSonic board

has these. It's a fairly common feature on sound boards with power amp

outputs.) The middle lead of one of the pots (either one) is a pretty

good bet as the place to connect the lead coming from the in-line

connector.
