CHAPTER 2

Biwiring Connections

If your speakers can be biwired or biamped, they will have completely separate input terminals for the woofer section and the upper range. See the speaker diagram and discussion on page 12.

Make sure that any links be- tween the woofer and upper

range posts are removed from the speakers when

you want to biamp or biwire them. Consult your speaker owner’s manual for details.

The front channels of the Cinema Grand AmpliÞer each have two pairs of outputs which can be used to biwire your speakers. The idea is to use the voltage source to drive the woofer, and the current source to drive the upper range. This will offer improved

The center and rear speakers have been omitted from this drawing for clarity. If your center speaker can be biamped, then connect it to the center channel outputs in the same way as shown above. Otherwise, connect it and the rear speakers as shown on pages 10 and 11.

Input connections

Connect your preampliÞer’s outputs to the ampliÞer’s corresponding input jacks. If your preampliÞer has XLR outputs, use these wherever possible.
