PREPARATION
■ Di-pole speaker layout
Either di-pole or direct radiating speaker types can be used
for THX surround. If you choose di-pole speakers, please
place the surround and surround back speakers according
to the speaker layout below.
Be sure to connect the left channel (L), right channel (R),
“+” (red) and “–” (black) properly. If the connections are
faulty, no sound will be heard from the speakers, and if the
polarity of the speaker connections is incorrect, the sound
will be unnatural and lack bass.
• If you will use 6 ohm speakers, be sure to set this unit’s speaker
impedance setting to 6 ohms before using (see page 31). If you
will use 8 ohm speakers, use this unit’s initial setting for
speaker impedance.
• Before connecting the speakers, make sure that this unit is
disconnected from the power source.
• Do not let the bare speaker wires touch each other or do not let
them touch any metal part of this unit. This could damage this
unit and/or speakers.
• Use magnetically shielded speakers. If this type of speaker still
creates interference with the monitor, place the speakers away
from the monitor.
A speaker cord is actually a pair of insulated cables running side
by side. One cable is colored or shaped differently, perhaps with a
stripe, groove or ridges. Connect the striped (grooved, etc.) cable
to the “+” (red) terminals on this unit and your speaker. Connect
the plain cable to the “–” (black) terminals.
■ Connecting to the speaker terminals
FRONT terminals
Connect one or two speaker systems to these terminals.
If you use only one speaker system, connect it to either of
the FRONT A or B terminals.
The Canada model cannot output to two pairs of speaker systems
simultaneously.
CENTER terminals
Connect a center speaker to these terminals.
SURROUND ZONE 2(3) terminals
Connect surround speakers to these terminals.
SUBWOOFER jack
Connect a subwoofer with a built-in amplifier, such as the
YAMAHA Active Servo Processing Subwoofer System,
to this jack.
SURROUND BACK terminals
Connect surround back speakers to these terminals.
If you only connect one surround back speaker, connect it
to the left (L) terminals.
