CAUTION:
When connecting two pairs of speaker systems simulta-
neously, the impedance of each speaker system should be
no less than 8 ohm .
Connecting a speaker system with a lower impedance than
8 ohm may activate the protection circuitry and make nor-
mal stereo reproduction impossible.
Connection 1 - 4 are recommended by Marantz for the SC-7S2 with Marantz MA-9S2s.
All Connections are based on speaker systems that are capable of Bi-Wiring.
Please read the instruction manual for the SC-7S2 for use. Name and Function ➔ P12
WIRING SPEAKER CABLE
• Be careful not to short circuit in wiring speaker cables.
• Peel off the corting of speaker cable as shown below.
• Wiring with speaker cable.
• Wiring with “Y” style terminal
BI-WIRING
The method is to improve sound quality, by connecting speaker
cable respectively to each terminal for Bass and Mid/High
speakers. This method will reduce interference caused by the
bass speaker and the Mid/High speaker unit being powered
by the same amplifier.
WIRING THE SPEAKER SYSTEM
7 Speaker system doesn’t comply
with the Bi-Wiring
Please connect either of the speaker terminals 1 or 2. And
please use a speaker system whose impedance is for 4 - 16Ω.
If impedance is lower than 4Ω, the protection circuit will be
engaged during play. This will result in no output of the Amplifier.

7 Polarity of Speaker output
terminal
Speaker terminals have positive (+ : Red) and negative (– :
White) polarity and speaker wires also have (+ & –) polarity. In
wiring, be sure to connect the terminals with the same polarity
(+ and +, – and –).
