Bi-amping your front speakers

VSX-915 model only

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.

2Select the SB BIAMP setting from the ‘SB. SYSTEM’ menu.

See Surround back speaker setting on page 46 to specify how you’re using the surround back speaker terminals.

Caution

•Most speakers with both Hi and Low terminals have two metal plates that connect the Hi 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

VSX-915 model only

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 SB NORM. or SB 2ND Z in Surround back speaker setting on page 46.

•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.
