! Place the surround speakers at 120º from
the center. If you, (1) use the surround
back speaker, and, (2) don’t use the front
height speakers / front wide speakers, we
recommend placing the surround speaker
right beside you.
! If you intend to connect only one surround
back speaker, place it directly behind you.
! Place the left and right front height speakers
at least one meter directly above the left and
right front speakers.
Connecting the speakers
Each speaker connection on the receiver com-
prises a positive (+) and negative (–) terminal.
Make sure to match these up with the terminals
on the speakers themselves.
CAUTION
! 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 core wires touch each
other or come in contact with the rear panel or
the metal parts of other speaker terminals, the
protective circuit may be activated, setting the
power to the standby mode.
Bare wire connections
CAUTION
Make sure that all speakers are securely
installed. This not only improves sound quality,
but also reduces the risk of damage or injury
resulting from speakers being knocked over or
falling in the event of external shocks such as
earthquakes.
1 Twist exposed wire strands together.
2 Loosen terminal and insert exposed
wire.
3 Tighten terminal.

Other speaker connections
! Your favorite speaker connections can be
selected even if you have fewer than 5.2
speakers (except front left/right speakers).
! When not connecting a subwoofer, connect
speakers with low frequency reproduction
capabilities to the front channel. (The
subwoofer’s low frequency component
is played from the front speakers, so the
speakers could be damaged.)
! After connecting, be sure to conduct the
Full Auto MCACC (speaker environment
setting) procedure. See Automatically
conducting optimum sound tuning (Full Auto
MCACC) on page 25.
