■ IMPEDANCE SELECTOR switch
CAUTION
Do not change the IMPEDANCE SELECTOR switch
while the power of this unit is turned on, as doing so may
damage the unit.
If the unit fails to turn on, the IMPEDANCE SELECTOR
switch may not be fully slid to either position. If this is the
case, remove the power cable and slide the switch all the
way to either position.
Select the switch position (LOW or HIGH) according to
the impedance of the speakers in your system.

• If you use one set (A or B), the impedance of
each speaker must be 8
• If you use two sets (A and B) simultaneously,
the impedance of each speaker must be 16

• If you make bi-wire connections, the
impedance of each speaker must be 8

• If you use one set (A or B), the impedance of

• If you make bi-wire connections, the
impedance of each speaker must be 4

■ Connecting speaker cables
Note
When inserting speaker cables into the speaker terminals, insert
only the bare speaker wire. If insulated cable is inserted, the
connection may be poor and sound may not be heard.

■ 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
or
SELECTOR switch to HIGH or LOW depending on the
impedance of your speakers:
8 Ω or higher: HIGH
4 Ω or higher: LOW
See page 11 for more information about the
IMPEDANCE SELECTOR switch.
Note
When making bi-wire connections, remove the shorting bridges
or cables on the speaker.

To use the bi-wire connections, press SPEAKERS A and
SPEAKERS B on the front panel or on the remote control so that
both SP A and B light up on the front panel display.
