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
connected 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)
