ONKYO A-9070 ユーザーズマニュアル

En

• 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.
