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
Ω and
16 Ω. When using both sets of terminals, the
connected speakers should have nominal
impedance between 8
Ω and 32 Ω. 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.

Using centralized control with other
Pioneer components
Multiple Pioneer components equipped with CONTROL
IN/OUT
jacks can be connected to the unit, allowing
centralized control of the components via the remote
sensor on the unit. This also allows remote control of
components not equipped with a remote sensor, or
installed in places where the component’s remote
sensor cannot be accessed.
Note
• For connections use a commercially available
monaural miniplug cord (without resistor).
• When connecting the CONTROL IN/OUT jacks,
commercially available audio cords must also be
used to make analog connections. Merely
connecting the CONTROL IN/OUT jacks alone will
not allow proper system control.
• When a control cord is connected to the unit’s
CONTROL IN jack, the unit cannot be controlled by
pointing the remote control at the unit (the remote
sensor is automatically disabled).
Digital audio input connections (A-70
only)
If a coaxial digital cable (sold separately) is used to
connect this unit’s DIGITAL IN COAXIAL terminal to the
digital audio output connector of a digital audio playback
component, the playback component can be used to
play music through this unit.
For more information regarding the output of audio
signals input to the DIGITAL IN COAXIAL terminal,
consult page 12.
Note
• Digital signal formats that can be input to this unit
include linear PCM signals with sampling rate and
quantitative bits up to 192 kHz/32 bits. (Depending
on the connected device and environment,
operation may not be successful).
