[. . . ] For both speakers A and B, make sure to connect them with Left and Right in pairs. 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") · If you connect both speaker sets to terminal A and B respectively to deliver sound at the same time, 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-9355/A-9155 at high volume levels for a long period of time, the built-in protection circuit may be activated. · If you use speakers with an impedance of 4 to 8 ohms, connect them to either terminal A or B, or otherwise do not use both speaker sets simultaneously to deliver sound. · 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. Make sure also the wires do not touch the rear panel. · Don't connect more than one cable to each speaker terminal. · Don't connect a speaker to more than one pair of speaker terminals. 2 3 Fully insert the bare wires. 4 Screw the terminal tight. The following illustration shows which speaker should be connected to each pair of terminals.

Doing so may adversely affect the sound quality. · To prevent interference, keep power cords and speaker cables away from the tuner's antenna. RCA Audio Connection Color Coding · Red connectors are used for the right channel, and white connectors are used for the left channel. Left (white) L Right (red) R · Push each plug in all the way to make a good connection (loose connections can cause noise or malfunctions). Right! Wrong! Audio Components Connecting a Turntable The A-9355/A-9155's PHONO input jacks are for use with moving-magnet (MM) type cartridges. Use an analog audio cable to connect the A-9355/A-9155's PHONO L/R jacks to the audio output jacks on the turntable, as shown. If your amplifier has shorting pin plugs, remove the shorting pin plugs before connecting your turntable. Connecting a CD Player Use an analog audio cable to connect the A-9355/A-9155's CD L/R jacks to the analog audio output jacks on the CD player, as shown. ANALOG OUT AUDIO OUT Ground wire Notes: · If the turntable has a ground wire, connect it to A-9355/A-9155's GND terminal. With some turntables, connecting the ground wire may cause hum, in which case it should be disconnected. [. . . ] · An audio cable may be picking up interference. Try repositioning your cables. The tone controls have no effect. · (A-9355) If the PURE DIRECT indicator lights up, the PURE DIRECT function is on and the tone controls have no effect. Press the [PURE DIRECT] button to turn the function off. The PURE DIRECT indicator will go off (page 16). [. . . ]
