PREPARATION Note • Do not bundle audio cables and speaker cables together with the power cable. Doing so may generate noise. • The PHONO jacks are designed for connecting a turntable with an MM cartridge. • Connect your turntable to the GND terminal to reduce noise in the signal. However, for some turntables, you may hear less noise without the GND connection. • If you have a Yamaha subwoofer that supports a system connection, you can switch the power of the subwoofer in conjunction with tuning on/off this unit by connecting the subwoofer to the TRIGGER OUT jack with a monaural miniplug cable. • In order to prevent the audio signal from looping when an audio recording device is connected, the audio signal is not output from the LINE 2 (OUT) jacks when LINE 2 is selected. Similarly, the audio signal is not output from the LINE 3 (OUT) jacks when LINE 3 is selected. Connecting the speakers Connections CAUTION Connect the speakers with impedance as shown below. If you connect speakers with an excessively low impedance, this unit may overheat. You can change the speaker impedance setting of this unit in "SP. IMP" (p. 52) in the ADVANCED SETUP menu. Speaker connection Speaker impedance (SP IMP.) 4 MIN 8 MIN (Default) SPEAKERS A or SPEAKERS B 4 Ω or higher 8 Ω or higher SPEAKERS A and SPEAKERS B 8 Ω or higher 16 Ω or higher Bi-wire connection 4 Ω or higher 8 Ω or higher ■ Connecting speaker cables Speaker cables have two wires. One is for connecting the negative (-) terminal of the unit and the speaker, and the other is for the positive (+) terminal. If the wires are colored to prevent confusion, connect the black wire to the negative and the other wire to the positive terminal. a Remove approximately 10 mm (3/8") of insulation from the ends of the speaker cable and twist the bare wires of the cable firmly together. b Loosen the speaker terminal. c Insert the bare wires of the cable into the gap on the side (upper right or bottom left) of the terminal. d Tighten the terminal. a 10 mm (3/8") c b d Note When inserting speaker cables into the speaker terminals, insert only the bare speaker wire. If insulated cable is inserted, the connection may be poor and sound may not be heard. ■ Connecting via banana plug (North America, Australia, General models only) Tighten the knob and then insert the banana plug into the end of the corresponding terminal.
