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 s 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. q Be careful not to short circuit or touch the speaker cables to each other. q Peel off the coating or insulation of the speaker cable as shown below. q Wiring with speaker cable. Approx. 1 cm s Wiring the speaker system q 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. q 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. q 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 -). s Wiring the speaker CAUTION: When connecting two pairs of speaker systems simultaneously, 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 normal stereo reproduction impossible. Cut the coating or insulation of the speaker cable. Peel off the edge of the cable. q Wiring with "Y" style terminal Twist conductors. Turn counter-clockwise to loosen. Insert conductor of cable. Turn clockwise to tighten. Connection 2 Stereo Bi-Amp connection. Turn counter-clockwise to loosen. Insert conductor. Turn clockwise to tighten. 5
