Bi-wire connection
The 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. This split connects the mid and high
frequency drivers to one set of terminals and the low
frequency driver to the other pair.
Caution
To use the bi-wire connections, the impedance of each speaker
must be 8 Ω or higher.
Notes
• Remove the shorting bars or bridges to separate the LPF (low
pass filter) and HPF (high pass filter) crossovers.
• To use the bi-wire connections, switch the SPEAKERS selector
to the A+B BI-WIRING position.

Connect your CD player with the XLR balanced output
jacks. The pin assignments for these jacks are shown
