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.

Using centralized control with other
Pioneer components (Except A-10)
Multiple Pioneer components equipped with CONTROL
IN/OUT jacks can be connected to the A-30/A-20 unit,
allowing centralized control of the components via the
remote sensor on the A-30/A-20. 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 A-30/A-
20's CONTROL IN jack, the unit cannot be
controlled by pointing the remote control at the A-
30/A-20 (the remote sensor is automatically
disabled).
Plugging in
Important
• When going on a trip or otherwise not using the
unit for an extended period, always disconnect the
power cord from its outlet. Note that various
internal settings will not be lost even if the power
cord is disconnected from its outlet for an extended
time.
• If it is necessary to detach the power cord, first be
sure to press the /I STANDBY/ON button on the
front panel of the unit so the A-30/A-20 is turned
OFF or the A-10 is in standby mode before
detaching the cord.
Caution
• The use of a power cord other than the one provided
will invalidate the warranty, since Pioneer will not
be responsible for any damage incurred. (The
power cord provided with the model A-30 has a
rated current capacity of 10 A, while the cord
provided with the A-20/A-10 has a rated current
capacity of 2.5 A.)
• Do not use any power cord other than the one
supplied with this unit.
• Do not use the supplied power cord for any purpose
other than that described below.
After you've finished making all connections, plug the
unit into an AC outlet.
