Bowers & Wilkins TECHNICAL SUPPORT
Remove the Terminal Links from each speaker (this separates LPF & HPF).
Connect each amplifier channel to its respective speaker section as shown in
Figure: 6.
Set the level controls on the amplifiers such that the signal will arrive at all speaker
terminals at the same power-volume level. If your amplifiers are identical, it is usually
sufficient to set all the amplifier level controls the same. The speaker's built-in
crossover is designed to match the efficiency of all the individual drivers (tweeters,
midranges, and woofers). When using the bi-amplifier connection you must directly
deal with some of these issues by adjusting levels according to your listening
preference.
