Remote Controller

Connections

Connecting Your Speakers

  • Screw-type speaker terminalsStrip 1/2″ to 5/8″ (12 to 15 mm) of insulation from the ends of the speaker cables, and twist the bare wires tightly, as shown.
  • Banana Plugs (North American models)
    • If you are using banana plugs, tighten the speaker terminal before inserting the banana plug.
    • Do not insert the speaker code directly into the center hole of the speaker terminal.

Note

  • Make sure that the wires do not touch metal parts on the back panel or elsewhere.
  • Y plugs cannot be connected.
  • Two sets of speakers (Speakers A and Speakers B) can be connected to the integrated amplifier. You can select which speakers to output audio to when listening to music. You can also output audio from both sets of speakers.
  • If you use Speakers A or Speakers B, make sure to use speakers with an impedance of 4 to 16 ohms. If you use Speakers A and Speakers B, make sure to use speakers with an impedance of 8 to 16 ohms. Connecting speakers with an impedance less than 8 ohms may cause the protection circuit to activate.
  • When using only one speaker, or when playing back monaural audio, don’t connect a single speaker to both the left and right speaker terminals.
  • 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 feel unnatural.
  • Be careful not to short the positive and negative wires. Doing so may damage the integrated amplifier.
  • Make sure the metal core of the wire does not have contact with the integrated amplifier’s rear panel. Doing so may damage the integrated amplifier.
  • Don’t connect more than one speaker wire to a single speaker terminal. Doing so could damage the integrated amplifier or cause it to malfunction.
Bi-wiring Connection

Bi-wiring provides improved bass and treble performance. Using terminals of both SPEAKERS A andSPEAKERS B, it separates high frequency from low frequency signals.

Important:

  • Bi-wiring can be used only with speakers that support bi-wiring and that have an impedance of 4-16 ohms.
  • When making the bi-wiring connections, be sure to remove the jumper bars that link the speakers’ tweeter (high) and woofer (low) terminals.
  • When making the bi-wiring connections, set SPEAKERS to A+B (➔ page 22).

Integrated Amplifier

Tip

  • As shown on the illustration, the wiring terminals of SPEAKERS A are connected to the tweeter and SPEAKERS B are connected to the woofer. However, wiring them the other way around is also possible.
Cable and Jacks

Note

  • Push plugs in all the way to make good connections (loose connections can cause noise or malfunctions).
  • To prevent interference, keep audio cables away from power cords and speaker cables.
  • The integrated amplifier’s optical digital jack have shutter-type covers that open when an optical plug is inserted and close when it’s removed. Push plugs in all the way.
  • To prevent shutter damage, hold the optical plug straight when inserting and removing.
  • Do not use digital audio signals other than PCM.* An analog audio cable can be used instead of a coaxial cable. However, we recommend that you use a coaxial or a composite video cable.
Connecting the Power Cord

  1. Connect all of your speakers and components.
  2. Connect the supplied power cord to the integrated amplifier’s AC INLET. (A-9050 only)
  3. Plug the power cord into an AC wall outlet.

Tip

  • To reduce noise, do not tie signal cables together with the power cable. Wire them so that they are away from each other.
  • Depending on the country, the integrated amplifier may be polarity-sensitive. In this case, plug the power cord in a way that provides the best sound quality.

Note

  • Never disconnect the power cord from the integrated amplifier while the other end is still plugged into a wall outlet. Doing so may cause an electric shock. Always disconnect the power cord from the wall outlet first, and then the integrated amplifier.
  • Turning on the integrated amplifier may cause a momentary power surge that might interfere with other electrical equipment on the same circuit. If this is a problem, plug the integrated amplifier into a different branch circuit.
  • Do not use a power cord other than the one supplied with the integrated amplifier. The supplied power cord is designed exclusively for use with the integrated amplifier and should not be used with any other equipment.

Adjusting the Volume
  • Operating with the remote controller

  1. Press VOLUME ^/v repeatedly.
  • Operating on the integrated amplifier

Tip

  • The default level is 0.
Selecting the Input Source

You can switch inputs to select the desired source component. Choose an input from the following: LINE1, LINE2, LINE3, LINE4, LINE5, PHONO (D1, D2, D3 (A-9050 only))The LED corresponding to the selected input will light up.

Tip

  • The LED will blink when D1, D2 or D3 is selected and a signal is not input. (A-9050 only)

Using the Direct Function

By bypassing the tone control circuit, the Direct function uses the shortest path for enhanced sound quality. Also, since the left/right balance setting uses a system that doesn’t affect the sound quality, the balance can be adjusted even if the Direct function is enabled.

Using the PHASE MATCHING BASS Function

From the warm low notes produced by a cello to the deep frequencies of electronic music, a good compact audio system should be able to deliver plenty of bass resonance. While traditional enhancement systems effectively boost low-frequency sound, they are often prone to the effects of phase shifting, which can overwhelm mid-range frequencies and muddy the sound.Our Phase-Matching Bass Boost technology effectively preserves mid-range clarity-allowing vocals and strings to shine-while maintaining a smooth, powerful bass response at all volume levels.

  1. Press the PHASE MATCHING BASS button. The PHASE MATCHING BASS LED lights up.
    • When the DIRECT function is on, turn the function off to use the PHASE MATCHING BASS effect.
Adjusting the Bass, Treble and Balance

Can’t turn on the Integrated Amplifier.• Make sure that the power cord is properly plugged into the wall outlet (➔ page 14).• Unplug the power cord from the wall outlet, wait 5 seconds or more, then plug it in again.

The Integrated Amplifier turns off unexpectedly.• When the protection circuit is activated (because of speaker short-circuit, overload, or over-current), the integrated amplifier enters Standby mode. Remove the source of the problem and turn the integrated amplifier back on.• Check that the switch on the back of the integrated amplifier is set to the correct setting ( ➔ page 25 ).• The settings are not enabled when the switch is changed during the Standby mode.To change a setting, be sure to turn on the unit prior to making any changes.

Audio

There’s no sound.• Make sure the integrated amplifier’s volume control is not set to minimum (➔ page 22).• Make sure the correct input source is selected (➔ page 23).• Make sure the integrated amplifier is not muted (➔ page 24).• Make sure the speakers are connected correctly ( ➔ page 12 ).• Check all connections and correct as necessary ( ➔ page 12 ).• While headphones are connected, the speakers output no sound (➔ page 24).• The integrated amplifier does not support digital formats other than PCM. Inputting a digital format other than PCM will cause loud noise.

The sound quality is not good.• Make sure the speaker cables are connected with the correct polarity (➔ page 12).• Make sure all audio connecting plugs are pushed in all the way (➔ page 14).• The sound quality can be affected by strong magnetic fields, such as those from a TV. Try moving any such devices away from the integrated amplifier.• If you have any devices that emit high-intensity radio waves near the integrated amplifier, such as a cellular phone that’s being used to make a call, the integrated amplifier may output noise.

Headphone output is intermittent or there’s no sound.• This may be due to dirty contacts. Clean the headphones plug. See your headphones’ instruction manual for cleaning information. Also, make sure that the headphones cable is not broken or damaged.

Audio performance• Audio performance will be at its best about 10 to 30 minutes after the integrated amplifier has been turned on and had time to warm up.• Using cable ties to bundle audio cables with speaker or power cables may degrade the sound quality, so refrain from doing it.• Depending on the country, the integrated amplifier may be polarity-sensitive. In this case, plug the power cord in a way that provides the best sound quality.• Install the integrated amplifier on a sturdy rack or shelf. Position it so that its weight is evenly dispersed on its four legs. Do not install the integrated amplifier in a place with vibration or an unstable location.• Plug the power cord into an AC wall outlet.

Onkyo Dock

There’s no sound.• Make sure that the Onkyo Dock is connected to the integrated amplifier properly.• Make sure that no video content is being played.• Reset the iPod.

Other• When the Auto Standby (ASb) function is activated, the power of the Onkyo Dock connected via u is automatically turned off (➔ page 25)

Can’t control properly by using the remote controller.• Make sure that the u cable is connected to the integrated amplifier correctly. Check that each device is connected correctly and that the RI MODE switch is set correctly (➔ page 17).

External Components

No sound is heard from a connected component.• Make sure the correct input source is selected (➔ page 23).• Make sure the analog audio cable is connected correctly (➔ page 14).

When the u interlock does not function properly• Check that each device is connected correctly and that the RI MODE switch is set correctly (➔ pages 15 to 17).• Check that the switch on the back of the integrated amplifier is set to the correct setting.• The settings are not enabled when the switch is changed during the Standby mode. To change a setting, be sure to turn on the unit prior to making any changes.• The connecting method may vary depending on the device that will be connected. Please refer to the RI connection section in the owner’s manual of the connected device.

The sound from turntable is distorted.• If your turntable has a built-in phono preamp, connect to other analog inputs such as LINE IN.• If your turntable does not have a built-in phono preamp, connect a turntable to PHONO (➔ page 19).• Make sure that the ground wire is connected. Otherwise, it may produce an audible hum and noise.

Remote Controller

The remote controller doesn’t work properly.• Make sure the batteries have been installed with the correct polarity (+/–) (➔ page 7).• Replace both batteries with new ones. (Do not mix different types of batteries or new and old batteries.)• The remote controller is too far away from the integrated amplifier, or there’s an obstacle between them (➔ page 7).• The integrated amplifier’s remote control sensor is being subjected to bright light (inverter-type fluorescent light or sunlight).• The integrated amplifier is located behind the glass doors of an audio rack or cabinet.

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.

The integrated amplifier 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 lockup. In the unlikely event that this should happen, unplug the power cord, wait at least 5 seconds, and then plug it again.

Before disconnecting the power cord from the wall outlet, set the integrated amplifier to Standby.

If during idling the cover is too hot to touch, then ventilation needs to be improved.
