SPEAKER OUTPUTS

Binding posts are provided for speaker connections. There is one pair provided for
each amplifier channel output. They are designed to accept a banana-type plug,
spade-lug connector (shown right), terminal posts, or bare wire. They are color
coded for easy identification. The positive (+) RED post should always be connect-
ed to the speakers (+) RED jack. The negative (-) BLACK post should always be
connected to the speakers (-) BLACK jack.

Shown right is the ampli-
fier to speaker connec-
tions (4 gauge (AWG)
wire maximum).
