Connection 1 - 4 are recommended by Marantz for the SC-7S1 with Marantz MA-9S1s.

All Connections are based on speaker systems that are capable of Bi-Wiring.

Please read the instruction manual for the SC-7S1 for use. Name and Function ➔ P12

■ Bi-Wiring

The method is to improve sound quality, by connecting speaker

cable respectively to each terminal for Bass and Mid/High speak-

ers. This method will reduce interference caused by the bass

speaker and the Mid/High speaker unit being powered by the

same amplifier.

●

Be careful not to short circuit or touch the speaker

cables to each other.

●

Peel off the coating or insulation of the speaker cable

as shown below.

■ Wiring the speaker system

●

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.

●

Speaker system complies with the Bi-Wiring

Please connect both of the speaker terminals 1 and 2.

And please use a speaker system whose impedance is

for 4 - 16Ω. If impedance is lower than 4Ω, protection

circuit will be engaged during play. This will result in no

output of the Amplifier.

●

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 po-

larity (+ and +, – and –).

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.
