Connecting the Speakers
Speakers
There are 6 speakers equipped with the unit (2 front, 1 cen-
ter, 2 rear, 1 subwoofer). In order to enjoy good surround
effects all six speakers need to be connected to the receiver
For better sound quality, center speaker, rear speakers and
Subwoofer should also be connected. Adding center and
rear speakers will enhance surround effects. Adding a
Subwoofer will increase bass response.
If you want to enjoy the full sound rangeuse the subwoofer
with the speakers to maintain adequate bass signal.
Speaker cords
1 for each speaker, is
needed for connection. Twist
the stripped ends of speaker
cord about 2/3 inch (15 mm).
Press down on the tab to
open the terminal and insert
the wire. Release tab to lock
wire in the terminal.
To ease speaker connections, the speaker cords and the ter-
minals are color-coded.
• White/Black (Front Left Speaker),
• Red/Black (Front Right Speaker),
• Green/Black (Center Speaker)
• Blue/Black (Rear Left Speaker).
• Grey/Black (Rear Right Speaker).
• Purple/Black (Subwoofer)
Connect the speaker wire to the back of L, R front speakers
and to the corresponding color terminals on the rear of the
receiver. Do the same for center speaker, rear speakers and
the subwoofer.
Speaker Polarity
When connecting the speakers, make sure the polarities
(“+” speaker wire to “+” on the receiver) of speaker wires
and terminals are matched. If the cords are reversed, the
sound will be distorted and will lack bass (“out of phase”
effect).
Do not ground the output line, it will cause damage to the
speaker.
Connecting the Subwoofer
Connect the subwoofer with the speaker wire (purple/
black) provided.
