Connecting Your Speakers

Speaker Connection Precautions

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 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. 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.

Connecting the Speaker Cables

1 Strip about 15mm (5/8 inch) of insulation from the ends of the speaker cables, and twist the bare wires tightly, as shown.

2 Unscrew the terminal.

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.

Before Making any Connections

• Always refer to the instructions that came with the component that you are connecting.
• Do not plug in the power cord until all connections have been properly made.
• Do not bind audio cables with power cords and speaker cables. 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.

• Push each plug in all the way to make a good connection (loose connections can cause noise or malfunctions).

Audio Components

Connecting a Turntable

The A-9355/A-9155's PHONO input jacks are for use with moving-magnet (MM) type cartridges.

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.

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.
• If the turntable has a moving-coil (MC) type cartridge, you'll need a commercially available MC phono preamp. In this case, connect the turntable to the phono preamp's input, and connect the phono preamp's output to the A-9355/A-9155's PHONO L/R jacks.

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.

Connecting a Tuner

Use an analog audio cable to connect the A-9355/A-9155's TUNER L/R jacks to the analog audio output jacks on the tuner, as shown.

Connecting a Cassette Deck

Use an analog audio cable to connect the A-9355/A-9155's TAPE IN L/R jacks to the cassette deck's analog audio output jacks, and use another analog audio cable to connect the A-9355/A-9155's TAPE OUT L/R jacks to the cassette deck's analog audio input jacks, as shown.

Connecting an MD Recorder

Use an analog audio cable to connect the A-9355/A-9155's MD IN L/R jacks to the MD recorder's analog audio output jacks, and use another analog audio cable to connect the A-9355/A-9155's MD OUT L/R jacks to the MD recorder's analog audio input jacks, as shown.

Connecting a Remote Interactive Dock (RI Dock)

Use an analog audio cable to connect the A-9355's DOCK Jack or A-9155's LINE/DOCK IN jack to the RI Dock's analog audio output jacks, and use an Rl cable to connect the A-9355/A-9155's Rl jack to the RI Dock's Rl jack, as shown.

* See page 13 to connect multiple audio components using Rl jacks.

Note:

If you use the Onkyo Remote Interactive Dock (DS-A1), flip the RI MODE switch to "HDD" which is located on the underside.

Connecting a TV or Other Component with an Audio Output

Use an analog audio cable to connect the A-9355's LINE/MD IN jack or A-9155's LINE/DOCK IN jack to the analog audio output jacks on the TV or other component, as shown.

Note:

If your TV has no audio output, you can connect the A-9355/A-9155 to an audio output on your VCR and use its tuner.

Connecting R1 Components

With RI (Remote Interactive), you can control your RI-compatible Onkyo CD player, Tuner, and so on with the A-9355/A-9155's remote controller. If you connect other Onkyo components to the A-9355/A-9155 with the appropriate RI and audio cables, you can use the following system functions. RI cables are special cables solely for use with Onkyo products (no RI cables are supplied with the A-9355/A-9155).

When you set the A-9355/A-9155 to Standby, all connected components will go on Standby as well (the A-9355/A-9155's POWER switch must be set to ON for this to work).

Direct Change

When playback is started on an audio component connected via R1, the A-9355/A-9155 will automatically select that component as the input source.

Remote Control Operation

You can control all components in your system by using the A-9355/A-9155's remote controller. See page 8 and 9 for more information.

• To use R1, you must make an analog audio connection between the A-9355/A-9155 and each audio component.

Notes:

• Push each plug in all the way to make a good connection.

• A-9355: The A-9355 has two RI jacks. If you want to connect two or more audio components to the A-9355, it is advisable to connect any of two components directly to the A-9355 for better audio quality, in stead of linking all the components using the daisy chain method.

• Use only dedicated RI cables for RI connections (no RI cables are supplied with the A-9355/A-9155).
• The A-9355 has two RI jacks. They're all the same, so you can use either of them.
• R1 jacks should be connected only to Onkyo components. Connecting them to another manufacturer's component may cause the A-9355/A-9155 to malfunction.
• Some components may not support all R 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 STANDBY/ON function, like Onkyo DX-7355 CD player. For Onkyo products equipped with RI terminals that have a STANDBY/ON function, allocate a normal outlet that is energized on a steady basis.

Note:

Do not connect any other devices than audio components.

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).

Connecting the Power Cord

• Before connecting the power cord, connect all your speakers and audio components.
• Turning on the A-9355/A-9155 may cause a momentary power surge, which might interfere with other electrical equipment on the same circuit. If this is a problem, plug the A-9355/A-9155 into a different branch circuit.

For home electric appliances which require a measureable amount of power, do not use the same wall outlet in which the A-9355/A-9155 is plugged so that the A-9355/A-9155 may operate under optimum conditions. Allocate them another wall outlet.
