Connecting the A-9355/A-9155 Connecting Your Speakers Speaker Connection Precautions Connecting the Speaker Cables You can connect one or two sets of speakers (A/B) to the A-9355/A-9155, and select which set outputs sound, or use both sets at the same time. For both speakers A and B, make sure to connect them with Left and Right in pairs. 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 oth- erwise 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 nega- tive (—) 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. Doing so may damage the A-9355/A-9155. Don't connect more than one cable to each speaker terminal. Doing so may damage the A-9355/A-9155. Don't connect a speaker to more than one pair of speaker terminals.

A-9355: The A-9355 has two F1 jacks. If you want 10 connect two or more audio components to the A- 9355, it is advisable to connect any of two compo- nents directly to the A-9355 for better audio quality, in stead of linking all the components using the daisy chain method. Use only dedicated fR1 cables for FRI connections (no fRI cables are supplied with the A-9355/A-9155). The A-9355 has two 1 jacks. They're all the same, so you can use either of them. +R jacks should be connected only to Onkyo compo- nents. Connecting them to another manufacturer's component may cause the A-9355/A-9155 to mal- function. Some components may not support all RI functions. See the manuals supplied with your other Onkyo components for more information. Connecting Another Component's Power Cord The A-9355/A-9155 has a switched AC OUTLETS on its rear panel. These can be used to connect the power cord of another audio component that you intend to use with the A-9355/A-9155. After you power on the A-9355/A-9155, you can feed or shut off power to the connected component by turning on or off the remote controller switch. Use the AC outlet of the A-9355/A-9155 to feed only components that have no STANDB Y/ON function, like Onkyo DX-7355 CD player. For Onkyo products equipped with RH ter- minals that have a STANDB Y/ON function, allocate a normal outlet that is energized on a steady basis. Note: Do not connect any other devices than audio compo- nents. A-9355 Caution: Make sure that the maximum power requirement of the component connected to the AC OUTLETS do not exceed the capacity printed on the A-9355/A-9155°s rear panel (100W).
