2-2 Speaker System Connections
•
This receiver can accommodate connectiorrs of a total of eight
speakers including two set of (front) main amplifier speakers
(A and 8), one set of rear speakers, and one or two center
speakers.
•
Connect the speaker terminals with the speakers making sure
that like polarities are matched (© with © , © with ©}.
Mismatching of polarities will result in weak central sound,
unclear orientation of the various instruments, and the sense
of direction of the stereo being impaired.
•
When making connections, take care that none of the indi
vidual conductors of the speaker cord come in contact with
adjacent terminals, with other speaker cord conductors, or
with the rear panel.
• Speaker Impedance
•
When speaker systems A and B are use separately,
speakers with an impedance of from 6 to 16 Q/ohms can
be connected.
•
Be careful when using two pairs of main speakers (A + 8) at
the same time, since use of speakers with an impedance
out^e the .range of 12 to 16 Q /ohms will lead to damage.
•
S'peakers with an impedance of 6 to 12 0/ohms can be
connected for use as center and rear speakers.
•
The protection circuit may operate or damage may occur
when speakers with an impednce outside of the above
range are used.

ANTENNA INSTALLATION
• Ш ANTENNA
The supplied FM antenna can be used inside wooden
houses for receiving local FM stations and other
strong FM signáis. Stretch out the ends of the
antenna and mount the antenna on the wall or ceiling
where optimum reception is achieved. A indoor FM
antennas may not consistentiy ensure stabie recep
tion, due to environment changes. In such cases, the
indoor FM antenna should only be used temporarily
until an outdoor FM antenna has been instaüed.
When connecting an outdoor FM antenna, the use of
75 ohm coaxial cable (ЗС-2У, 5C-2V) is strongiy
recommended.
. AM ANTENNA
Attach the supplied AM loop antenna even when
using an outdoor AM antenna.
Connect the leads to the AM and GNO termináis.
Also use the AM terminals for connecting an outdoor
AM antenna (when.making such a connection do not
disconnect the AM loop antenna.)
Adjust the loop antenna to obtain optimum recep
tion, Where broadcast stations are distant and only
weak signals are received, or where signals are
blocked, it is best to tnstaii an outdoor AM antenna.
NOTES
• This receiver has a full back-up system. When the
power is turned on, the INPUT SELECTOR buttons
are set to the last mode set before the power was
turned off.
• When using this receiver in close proximity to video
equipment {TV, VCR, VOP, etc.), noise may be
generated in AM broadcasts. To avoid this, keep the
receiver as far away from other video components as
possible, or detach the AM loop antenna from the
antenna holder and place it where noise is reduced. If
the noise is not reduced, turn off the power of the
video components when Üstening to AM broadcasts.
Note to CATV system instalier:
This reminder is provided to call the CATV system
installer's attention to Article 820-40 of the NEC which
provides guidelines for proper grounding and, in
particular, specifies that the cabie ground shali be
connected to the grounding system of the building, as
close,to the point of cabie entry as practical.
