Ok, this is how you connect all your speakers on the rear of your nice Marantz SR5003:
.Rear of the SR5003................Rear of the speakers................
Front Left A + = Speaker wire + to the left front speaker.
Front Left A - = Speaker wire - to the left front speaker.
Front Right A + = Speaker wire + to the right frontspeaker.
Front Right A - = Speaker wire - to the right front speaker
Center speaker + = Speaker wire + to the center speaker.
Center speaker - = Speaker wire - to the center speaker.
Surround Left + = Speaker wire + to the left side surround speaker.
Surround Left - = Speaker wire - to the left side surround speaker.
Surround Right + = Speaker wire + to the right side surround speaker.
Surround Right - = Speaker wire - to the right side surround speaker.
Surround Back Left + = Speaker wire + to the left rear surround speaker.
Surround Back Left - = Speaker wire - to the left rear surround speaker.
Surround Back Right + = Speaker wire + to the right rear surround speaker.
Surround Back Right - = Speaker wire - to the right rear surround speaker.
Front Left B + = Speaker wire + to the left speaker of the 2nd room.
Front Left B - = Speaker wire - to the left speaker of the 2nd room.
Front Right B + = Speaker wire + to the right speaker of the 2nd room.
Front Right B - = Speaker wire - to the right speaker of the 2nd room.
* Now you got an extra receiver from Harman Kardon.
You can use it to power the speakers in the 2nd room instead of the Marantz Front B speakers Left and Right.
Here's how:
...Rear of the SR5003............Rear of the Harman Kardon............
Zone 2 Out Left (white) = Interconnect white cable to "CD In" left (white).
Zone 2 Out Right (red) = Interconnect red cable to "CD In" right (red).
Set your receiver (Sr5003) from the speaker setup menu to enable Zone 2.
Set the Input (source) on your Harmasn Kardon to CD.
Would you like me to come over and plug the power cord for you?
What I just type for you, is only because I'm in a pretty good mood today, and it's your lucky day. [Must be because today they just found my 47 million years old grandmother or aunt ancestor]
But if you read your instruction manual of your SR5003, it is clearly indicated.
If you don't have a manual, you can download it from Marantz web site.
Cheers,
Bob
