Easy Setup and Operation
• Basic system layout
The following is an example ef the basic layout fer a system censisting of eight speaker systems
and a televisien meniter:
Center speaker system
Surround back speaker systems
r
Front speaker systems
Set these at the sides ef the TV
er screen with their front surfaces
as flush with the front of the
screen as possible.
Surround speaker systems
Easy Setup and Operation
o Cennect the speaker terminals with the
speakers making sure that like pelarities are
matched (@ with @, _ with _). Mismatching
ef polarities will result in weak central sound,
unclear orientation of the various instruments,
and the stereo image being impaired.
"When making connections, take care that
none of the individual conductors ef the speaker
cable come in contact with adjacent terminals,
with other speaker cable conductors, er with
the rear panel.
NOTE:
NEVER touch the speaker terminals
when the power is on. Doing so could
result in electric shocks,
• Speakerimpedance
,'When speaker systems A and B are used
separately, speakers with an impedance of 6
to 16 _/ohms can be cennected for use as
front speakers.
• Be careful when using twe pairs of frent
speakers (A + B) at the same time, since
speakers with an impedance of 12 te 16
_/ohms in this case must be used.
• Speakers with an impedance of 6 to 16
_/ohms can be connected for use as center
and surround and surround back speakers.
• The pretector circuit may be activated if the
unit is operated for leng perieds of time at
high w)lumes when speakers with an
impedance lewer than the specified
impedance are connected.
The pretecter circuit may be activated if the
unit is operated for long periods ef time at
high w)lumes when speakers with an
impedance lower than the specified
impedance (for example speakers with an
impedance ef less than 4 _/ehms) are
connected. If the pretecter circuit is
activated, the speaker output is cut off. Turn
eff the unit's power, wait fer the unit te ceel
down, improve the ventilation areund the
unit, then turn the power back en.

the banana plug.
This uni_ is equipped wi_h a high-speed
pretection circuit. The purpose of this circuit
is to pretect the speakers under circumstances
such as when the output of the power
amplifier is inadvertently shert-circuited and
a large current flews, when the temperature
surrounding the unit becomes unusually
high, er when the unit is used at high output
ever a leng peried which results in an
extreme temperature rise.
When the pretectien circuit is activated, the
speaker output is cut off and the power
supply indicater flashes. Should this eccur,
please fellew these steps: be sure to switch
off the power of this unit, check whether
there are any faults with the wiring of the
speaker cables or input cables, and wait fer
the unit to cool down if it is very het.
Improve the ventilation condition around the
unit and switch the power back en.
If the protection circuit is activated again
even though there are no problems with the
wiring or the ventilation areund the unit,
switch off the power and contact a DENON
service center.
