Connecting Speaker Cables; Connecting Audio Cables; Connecting To The Balanced Input Terminals (A-70Da Only) - Pioneer A-70DA-K Manual De Instrucciones

02 Connecting up
• 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

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.
