Connecting 5.1-channel speaker system with bi-amplifier connection

You can enhance the sound quality of the front speakers by separately connecting the built-in amplifiers to tweeters and woofers in a bi-amplifier configuration.

If you are not using surround back speakers or height/overhead speakers, you can connect the front speakers to the SPEAKERS SURROUND BACK/HEIGHT terminals using a bi-amplifier connection. Connect each speaker as illustrated below.

Before connecting cables, be sure to disconnect the AC power cord (mains lead).

For details on how to connect speaker cables to the receiver, see “How to connect speaker cables.”

Connecting front speakers with bi-amplifier connection

Connect the jacks on the Lo (or Hi) side of the front speakers to the SPEAKERS FRONT A terminals, and connect the jacks on the Hi (or Lo) side of the front speakers to the SPEAKERS SURROUND BACK/HEIGHT terminals.

Make sure that metal fittings of Hi/Lo attached to the speakers have been removed from the speakers to avoid receiver malfunction.

After you have made the bi-amplifier connection, set [Surround Back Speaker Assign] to [BI-AMP] in the [Speaker Settings] menu.


  • Connect speakers with a nominal impedance of 6 ohms to 16 ohms.
  • After you have installed and connected your speakers, be sure to select the speaker pattern you want using [Speaker Pattern] in the [Speaker Settings] menu.
  • You can only set [Surround Back Speaker Assign] if the speaker pattern is set to a setting that does not have surround back and height/overhead speakers.
