En
• When using speakers with removable network
circuits, note that if the network is removed, no
effect will be produced and damage may be caused
to the speaker.
• Another method of connection is to connect the
SPEAKERS A
terminals to HIGH and the
SPEAKERS
B
terminals to LOW (reverse that shown in the
illustration).
Connecting speaker cables
1
Twist the cable cores.
2
Loosen the nut on the SPEAKERS
terminal, and insert the speaker cable into
the exposed hole in the terminal shaft.
3
Retighten the terminal nut.
Caution
• When using only one set of speaker terminals
(SPEAKERS A or SPEAKERS B), or when utilizing
bi-wiring connections, the speaker used should
have a nominal impedance between 4
and
16
. When using both sets of terminals, the
connected speakers should have nominal
impedance between 8
and 32
. Consult the
instructions accompanying your speakers for
details regarding the impedance value.
• Make sure the positive and negative (+/–) terminals
on the amplifier match those on the speakers.
• These speaker terminals carry
HAZARDOUS live
voltage
. To prevent the risk of electric shock when
connecting or disconnecting the speaker cables,
disconnect the power cord before touching any
uninsulated parts.
• Make sure that all the bare speaker wire is twisted
together and inserted fully into the speaker
terminal. If any of the bare speaker wire touches the
back panel it may cause the power to cut off as a
safety measure.
Connecting audio cables
Connect the white plug to the left (L) jack, and the red
plug to the right (R) jack. Be sure to insert the plugs fully
into the jacks.

terminals of the unit to a
SACD player, USB DAC, network player, or other device
with balanced output terminals.
Caution
• The
BASS
,
TREBLE
,
BALANCE
, and
LOUDNESS
functions do not work for a device connected to the
BALANCED
IN
terminals.
The phase may differ depending on the device to be
connected. Use the phase selector switch on the rear
panel of the unit to match the phase.
•
Initial setting (No. 2 HOT)
•
Settings when polarity changed
(No. 3 HOT)
Note
• For details on the phase of the balanced output
terminals of the device to be connected, refer to the
instruction manual of the device.
• When connecting the unit to a Pioneer player,
match the phase to the initial setting (No. 2 HOT).
