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

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 with speaker cable.
● Wiring with “Y” style terminal
Connection 2 Stereo Bi-Amp connection.
■
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 -
16
Ω. 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 - 16
Ω. 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 –).

Peel off the edge
of the cable. Twist conductors.

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.
