CONNECTIONS

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

ENGLISH

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

7Speaker 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. If impedance is lower than 4, the protection circuit will be engaged during play.This will result in no output of the Amplifier.

7Polarity 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 –).

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.
