•Use the SPEAKERS button on the front panel to select a speaker system setting.

As mentioned above, if you have selected Normal, the button will simply switch your main speaker system (A) on or off.

Press repeatedly to choose a speaker system option:

•SPA – Sound is output from speaker system A and the same signal is output from the pre-out terminals.

•SPB – Sound is output from the two speakers connected to speaker system B. Multichannel sources will not be heard. The same signal is output from the surround back channel pre-out terminals.

•SPAB – Sound is output from speaker system A (up to 5 channels, depending on the source), the two speakers in speaker system B, and the subwoofer. The sound from speaker system B will be the same as the sound from speaker system A (multichannel sources will be downmixed to 2 channels).

•SP(off) – No sound is output from the speakers. The same sound is output from the pre-out terminals (including from your subwoofer, if connected) as when selecting speaker system A (above).

Bi-amping your front speakers

Bi-amping is when you connect the high frequency driver and low frequency driver of your speakers to different amplifier (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.

1 Connect 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.

High

Low

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 (High or Low) of the speaker.

•Make sure that the + / – connections are properly inserted.

2Select the ‘Front Bi-Amp’ setting from the Surround Back System menu.

See Surround back speaker setting on page 41 to specify how you’re using the surround back speaker terminals.

Caution

•Most speakers with both High and Low terminals have two metal plates that connect the High to the Low terminals. These must be removed when you are bi-amping the speakers or you could severely damage the amplifier. See your speaker manual for more information.

•If your speakers have a removable crossover network, make sure you do not remove it for bi-amping. Doing so may damage your speakers.

Bi-wiring your speakers

The reasons for bi-wiring are basically the same as bi- amping, but additionally, interference effects within the wire could be reduced, producing better sound. Again, to do this your speakers must be bi-wireable (that is they must have separate terminals for the high and low frequencies). When bi-wiring, make sure you’ve selected Normal or Speaker B in Surround back speaker setting on page 41.

•To bi-wire a speaker, connect two speaker cords to the speaker terminal on the receiver.

Caution

•Make sure you use a parallel (not series, which are fairly uncommon) connection when bi-wiring your speakers.

•Don’t connect different speakers from the same terminal in this way.
