For both speakers A and B, make sure to connect them with Left and Right in pairs. If you connect either Left or Right channel alone, no sound output will be available. If the electrical contact is poor for the connection, the Volume indicator will flash quickly when the power is supplied. Connecting the Speaker Cables 1 Strip about 15 mm (5/8 inch) of insulation from the ends of the speaker cables, and twist the bare wires tightly, as shown. Unscrew the terminal. 15 mm (5/8") 2 3 · Connecting one set of speakers (A or B): Only connect speakers with an impedance of 4 ohms or more but less than 16 ohms. If you use speakers with a lower impedance, and use the A-9755/A-9555 at high volume levels for a long period of time, the built-in protection circuit may be activated. · Connecting two sets of speakers (A and B): Only connect speakers with an impedance of 8 ohms or more but less than 16 ohms. If you use speakers with a lower impedance, and use the A-9755/A-9555 at high volume levels for a long period of time, the built-in protection circuit may be activated. · Disconnect the power cord from the wall outlet before making any connections. · Read the instructions supplied with your speakers. · Pay close attention to speaker wiring polarity. In other words, connect positive (+) terminals only to positive (+) terminals, and negative (­) terminals only to negative (­) terminals. If you get them the wrong way around, the sound will be out of phase and will sound unnatural. · Unnecessarily long or very thin speaker cables may affect the sound quality and should be avoided. · Be careful not to short the positive and negative wires. · Don't connect more than one cable to each speaker terminal. · Don't connect a speaker to more than one pair of speaker terminals. Fully insert the bare wires. 4 Screw the terminal tight. The following illustration shows which speaker should be connected to each pair of terminals.
