■ Bi-wire connection
Bi-wire connection separates the woofer from the
combined midrange and tweeter section. A bi-wire
compatible speaker has four binding post terminals. These
two sets of terminals allow the speaker to be split into two
independent sections. With these connections, the mid and
high frequency drivers are connected to one set of
terminals and the low frequency driver to another set of
terminals.
This unit
Connect the other speaker to the other set of terminals in
the same way.
CAUTION
When making bi-wire connections, set the IMPEDANCE
SELECTOR switch to HIGH or LOW depending on the
impedance of your speakers:
6 Ω or higher: HIGH (Taiwan and Central/South
America models)
8 Ω or higher: HIGH (Asia model)
4 Ω or higher: LOW
See page 4 for more information about the IMPEDANCE
SELECTOR switch.
Note
When making bi-wire connections, remove the shorting bridges
or cables on the speaker.
