Alternating surround speaker setups using speaker system B (ITU-R)

After you connect an alternate set of surround speakers, you can use speaker system B to provide surround sound when listening to sources like DVD-Audio discs. This will give you a setup of 9 speakers where the front and center speakers can be used with normal 7.1 surround (speaker system A), or 5.1 surround with DVD-Audio sources (speaker system B in ITU-R setting).

1Connect an alternate (ITU-R) set of surround speakers as shown below.

Connect the ITU-R surround left speaker to the left speaker terminal of speaker system B. Connect the ITU-R surround right speaker in the same way.

•Make sure that the + / – connections are properly inserted (A and B speaker systems are opposite).

2Select the ‘ITU-R’ setting from the Speaker Systems menu.

See Speaker Systems on page 52 to specify how you’re using speaker system B. Normal Surround should be selected to make this setting.

3Use the SPEAKER A/B button on the remote control amplifier menu screen to select a speaker system setting.

You can also use the SP SYSTEM A/B button on the front panel.

Choose between the following settings (the shaded boxes indicate the active speakers in each setup):

• SP A: Normal – Normal surround (for movies, etc.)

76

• SP B: ITU-R– ITU-R surround setup for DVD-Audio and other multichannel music sources. See Speaker system setup for DVD-Audio/multichannel music sources on page 91 for more on this.

• SP OFF– No sound is output from the speakers.

Note

•Depending on the Stream Direct mode, the surround channel signal(s) will be output from either the surround, or surround back channel pre-outs when

SP B: ITU-R is selected.

Bi-amping your front speakers

Bi-amping is when you connect the high frequency driver and low frequency driver of your speakers to different amplifiers (in this case, to both front and surround back terminals) for better crossover performance. Your speakers must be bi-ampable to do this (having separate terminals for high and low) and the sound improvement will depend on the kind of speakers you’re using.

1Connect your speakers as shown below. This illustration below shows the connections for bi- amping your front left speaker. Hook up your front right speaker in the same way.

Since both front and surround back speaker terminals output the same audio, it doesn’t matter which set (front or surround back) is powering which part (Hi or Low) of the speaker.

•Make sure that the + / – connections are properly inserted. (A and B speaker systems are opposite).
