N212 biased network - JBL L212 Loudspeaker System.

[4313B]

One battery per network.

You attach the negative lead of the battery to the negative input rail of the loudspeaker system. The positive lead of the battery goes to one side of all the 3.0 Mohm resistors. The other ends of the 3.0 Mohm resistors go to each of the capacitor pairs.
