The sound quality some-
times

Connecting the speakers
Use high current capacity con-
necting cords and do not make
them longer than necessary.
INSTALLATION
PRECAUTIONS
Listening position is slight-
ly to the apex of an equi-
lateral triangle formed with
left and right speakers.
Thick curtains
e Use curtains to shade the stereo
system
from the direct rays of
the sun.
eCurtains
also
help
to
reduce
resonance
and
reverberation
in
the listening room.
Speaker system
e@ install the speakers to the left and right so
that they are subject to the same conditions
both to the side and at the back. (The bass
is more
pronounced
if you
set them
up
against a wall.)
e Install
the
speakers
so that they are not
affected
by vibration
transmitted
through
the floor.
locations described below:
Locations liable to downgrade performance
and result in breakdowns
. Locations exposed to direct sunlight, or near heaters.
. Locations with poor ventilation, with high humidity or mois-
ture contents, or dusty locations.
. Locations susceptible to vibration.
Resulting trouble
. External heat causes the performance of the electronic parts to
deteriorate, and operation becomes unstable.
. Cause of faulty contact
in input-output terminals, and rust.
High humidity and a high moisture content cause deterioration
in insulation. There is also the danger of current leakage and
heat generation in the circuit parts. Dust or grease in the rotat-
ing parts causes them to deteriorate.
. These locations affect the precision parts adversely.
