• The remote controller will not work if there's an obstacle between it and the A-9377's remote control sensor.

Connecting Your Speakers

You can connect one or two sets of speakers (A/B) to the A-9377 and select which set outputs sound, or use both sets simultaneously.

Speaker Connection Precautions

• Always connect speakers in pairs.
• If you want to output sound from speaker sets A and B simultaneously, you must use speakers with an impedance of 8 to 16 ohms. If you connect speakers with a lower impedance, and use the A-9377 at high volume levels for a long period, the built-in protection circuit may be activated.
• If your speakers have an impedance of 4 to 8 ohms, connect them to either the SPEAKERS A or SPEAKERS B terminals, or do not output sound from both speaker sets simultaneously.
• 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-9377.
• Do not connect more than one cable to each speaker terminal. Doing so may damage the A-9377.
• Do not connect a speaker to more than one pair of speaker terminals.

Connecting the Speaker Cables

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

Connecting Your Components

Audio Connection Precautions

• Always refer to the instruction manual that came with the component you are connecting.
• Do not plug in the power cord until all connections have been made.

RCA 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).

• 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.

Connecting a Turntable

The A-9377's PHONO input is designed for use with a turntable fitted with a moving-magnet (MM) cartridge. Use an analog audio cable to connect the A-9377's PHONO L/R jacks to the audio output jacks on the turntable, as shown. If there are RCA shorting plugs in the jacks, remove them before connecting.

Notes:

• If the turntable has a ground wire, connect it to A-9377'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 head amp or transformer. In this case, connect the turntable to the head amp or transformer, and connect that to the A-9377's PHONO L/R jacks.

Connecting a CD Player

Use an analog audio cable to connect the A-9377'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-9377'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-9377'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-9377's TAPE OUT L/R jacks to the cassette deck's analog audio input jacks, as shown.

Connecting an Onkyo RI Dock

Use an analog audio cable to connect the A-9377's DOCK L/R jacks to the RI Dock's analog audio output jacks, and use an RI cable to connect the A-9377's RI jack to the RI Dock's RI jack, as shown.

• See page 14 if you need to connect several Rl-capable Onkyo components to the A-9377.

Note:

• If you have an RI Dock such as the DS-A1 or DS-A2, set its RI MODE switch to "HDD" or "HDD/DOCK." Refer to the RI Dock's instruction manual for details.

Connecting a Component with a Line Output (TV, game console, etc.)

Use an analog audio cable to connect the A-9377's LINE L/R jacks to the line output jacks on the TV or other component, as shown.

Note:

• If your TV doesn't have an audio output, connect your VCR's audio output to the A-9377, and use your VCR's tuner to listen to the TV.

Connecting a Power Amplifier

You can use the A-9377 as just a preamplifier and connect it to a more powerful power amplifier.

Use an analog audio cable to connect the A-9377's PREOUT L/R jacks to the analog audio input jacks on the power amplifier, as shown.

Note:

• Signals output by the PREOUT jacks are not affected by the A-9377's Volume, BALANCE, BASS, and TREBLE controls.
• When the A-9377 is connected to a power amplifier, if the power amplifier is off and the A-9377 is used on its own, the sound may be distorted. To prevent this, always turn on the power amplifier, or disconnect it from the A-9377.

Connecting R1 Components

Connecting the A-9377 to your other Onkyo R1-capable components with R1 cables allows you to control them all with the A-9377's remote controller, like an integrated system, with the following functionality.

Direct Change

When playback is started on a component connected with RI, the A-9377 will automatically select that component as the input source.

Remote Control

You can control components connected with from the A-9377's remote controller. See page 9 for details.

To use all Rl functionality, in addition to an Rl connection, each component must be connected to an analog audio input on the A-9377.

Notes:

• Push plugs in all the way to make good connections.
• RI cables are special cables solely for use with Onkyo products (no RI cables are supplied with the A-9377). Use only RI cables for RI connections.
• Connect RI jacks to only RI-capable Onkyo components. Connecting them to other manufacturers' component may cause a malfunction.
• Some RI-capable Onkyo components may not support all RI functionality. Refer to each component's instruction manual for full details.

Power Connections

Connecting the Power Cords of Other Components

The A-9377 has switched AC outlets on its rear panel that can be used to connect the power cords of other components that you intend to use with the A-9377.

These components can then be left turned on so that they turn on and off as and when the A-9377 is turned on and off.

Use the AC outlets for components that have no Standby function, such as the Onkyo CD Player. RI-capable Onkyo components with a Standby function must be connected directly to a wall outlet.

Cautions:

• Connect only audio components to the AC OUT-LETS.

LINE: Component connected to the LINE jacks.

PHONO: Turntable connected to the PHONO jacks.

CD: Component connected to the CD jacks.

OFF: Nothing is output by the TAPE OUT L/R jacks.

TUNER: Component connected to the TUNER jacks.

DOCK: Component connected to the DOCK jacks.

SOURCE: Component selected by the Input Selector.

2 Prepare the recorder:

• Set the recorder so that it's ready for recording.
• If necessary, adjust the recording level on the recorder.
• See the recorder's instruction manual for more information.

3 Start playback on the source component.

Notes:

• Signals output by the TAPE OUT L/R jacks are not affected by the A-9377's Volume, BALANCE, BASS, and TREBLE controls.
• If you're using an Onkyo cassette deck that's connected via R1, for dubbing or synchro recording, set the REC SELECTOR to SOURCE.

If you have any trouble using the A-9377, look for a solution here. If you cannot resolve the issue yourself, contact your Onkyo dealer.

Power

Cannot turn on the A-9377.

• Make sure that the power cord is properly plugged into the wall outlet.
• Unplug the power cord from the wall outlet, wait ten seconds or more, then plug it in again.

The SPEAKERS A and B indicators are both flashing.

• The amp protection circuit has been activated. Set the POWER switch to OFF immediately, remove the power cord from the wall outlet, and contact your Onkyo dealer.

Audio

There's no sound or it's very quiet.

• Make sure that all audio plugs are pushed in all the way (page 12).
• Make sure that the inputs and outputs of all components are connected properly.
• Make sure that the polarity of the speaker cables is correct and that the bare wires are in contact with the metal part of each speaker terminal (page 11).
• Make sure that the correct input source is selected (page 16).
• If the MUTING indicator is flashing, press the remote controller's [MUTING] button to unmute the A-9377 (page 16).
• Make sure that none of the cables are bent, twisted, or damaged.
• If your turntable uses an MC type cartridge, you must use an MC head amp or MC transformer (page 12).
• Make sure the SPEAKERS selector is set correctly. If it's set to OFF, no speakers will output sound (page 15).

Noise can be heard.

• Using cable ties to bundle audio cables with power cords, speaker cables, and so on may degrade the audio performance, so do not bundle them together.
• An audio cable may be picking up interference. Try repositioning your cables.

The tone controls have no effect.

• If the TONE/DIRECT indicator is on, the Direct function is on and the tone controls have no effect. Press the [TONE/DIRECT] button to turn the function off. The TONE/DIRECT indicator will go off (page 16).

Remote Controller

The remote controller doesn't work.

• Make sure that the batteries are installed with the correct polarity (page 10).
• Try installing new batteries. Do not mix different types of batteries or old and new batteries (page 10).
• Make sure that the remote controller is not too far away from the A-9377 and that there's no obstruction between the remote controller and the A-9377's remote control sensor (page 10).
• Make sure that the A-9377 is not subjected to direct sunshine or inverter-type fluorescent lights. Relocate if necessary (page 10).
• If the A-9377 is installed in a rack or cabinet with colored glass doors, the remote controller may not work reliably when the doors are closed (page 10).

Cannot control other components?

• If it's an Onkyo component, make sure that the RI cable and analog audio cable are connected properly. Connecting only an RI cable will not work. (page 14)

The A-9377 contains a microcomputer for signal processing and control functions. In very rare situations, severe interference, noise from an external source, or static electricity may cause it to lock up. In the unlikely event that this happens, unplug the power cord from the wall outlet, wait at least ten seconds, and then plug it back in again.

Onkyo is not responsible for damages (such as CD rental fees) due to unsuccessful recordings caused by the unit's malfunction. Before you record important data, make sure that the material will be recorded correctly.
