noise when connecting the unit to components

such as an analog turntable.

• Do not connect the PHONO (MM) terminals to any

component other than a turntable; also, do not

connect to a turntable equipped with built-in

equalizer. An excessively high sound output may be

produced, resulting in damage to your speakers or

other devices.

• The unit’s PHONO (MM) terminals are designed to

be used with turntables equipped with MM

(moving-magnet) type cartridges. Turntables

equipped with MC (moving-coil) cartridges cannot

be used.

• Make sure not to bend the cables over the top of

this unit (as shown in the illustration). If this

happens, the magnetic field produced by the

transformers in this unit may cause a humming

noise from the speakers.

• The unit’s POWER AMP DIRECT terminals should

never be connected to any other component’s

connectors except PRE-AMP OUT.

• If your turntable has a grounding wire, secure it to

the ground terminal on this amplifier.

This unit can be used with speakers that support bi-

wiring. Be sure to connect the high-frequency and

low-frequency connections correctly.

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.

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.

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.
