Please use the following guide to connect your passive speakers to the A-9030/A-9050 Integrated Amplifier. 

Screw-Type Speaker Terminals

Strip 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

Bi-Wiring

Bi-wiring provides improved bass and treble performance.  Using terminals of both SPEAKERS A and SPEAKERS 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 8-16 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

Tip:

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

Please 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. as it may damage the integrated amplifier
• Make sure the metal core of the wire does not have contact with the integrated amplifier’s rear panel as doing so may damage the integrated amplifier
  
• Don’t connect more than one speaker wire to a single speaker terminal as doing so could damage the integrated amplifier or cause it to malfunction

If there is no sound:

• Make sure the integrated amplifier’s volume control is not set to minimum
• Make sure the correct input source is selected
• Make sure the integrated amplifier is not muted
• Make sure the speakers are connected correctly
• While headphones are connected, the speakers output no sound

If the sound is distorted or sound quality is not good:

• Make sure the speaker cables are connected with the correct polarity
• The integrated amplifier does not support digital formats other than PCM. Inputting a digital format other than PCM will cause loud noise.
• Check that the switch on the back of the integrated amplifier is set to the correct setting.
• Make sure all audio connecting plugs are pushed in all the way
• 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
• Using cable ties to bundle audio cables with speaker or power cables may degrade the sound quality, so refrain from doing it
• Plug the power cord into an AC wall outlet
• 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.
