5. Bi-wiring Connections to Speakers

The Bi-wire connection separates the woofer/midrange from the tweeter section.
These two sets of terminals allow the speakers to be split into two independent
sections. The split connects the mid and high frequency drivers to one set of
terminals and the low frequency driver to the other pair. In the bi-wire connection the
Terminal Links are removed and separate sets of speaker wire are run from the
amplifier to each section as shown in Figure: 5.
Connect speakers in the bi-wire mode:

Ensure that your system is powered OFF.

Remove the Terminal Links from speakers (this separates the LPF & HPF).

Connect each amplifier channel to its respective speaker section as shown.

6. Bi-Amplification Connections to Speakers

Bi-amplification is the use of two amplifiers for both speakers with one amplifier
connected to the woofer section of a loudspeaker while the other is connected to the
tweeter section. With this arrangement each amplifier operates over a restricted
frequency range. This restricted range presents each amplifier with a much simpler
job and each amplifier is less likely to "influence" the sound in some way.
Connect speakers in the bi-amplification mode:

Ensure that your system is powered OFF.
