Marantz MA-9S1 manual Connections, Bi-Wiring, Wiring the speaker system

4. Connections

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.

■Wiring the speaker system

●Speaker system doesn’t comply with the Bi-Wiring

●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 “Y” style terminal

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 –).

■Wiring the speaker

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.
