INSTALLATION
When
installing
the
deck,
avoid
locations
with
high
temperature
or
humidity,
and
be
sure
that
the
location
is
well
ventilated.
Do
not
install
the
deck
in
locations
subject
to
direct
sunlight,
or
next
toa
space
heater
or
other
heating
device,
since
the
finish
or
internal
parts
may
be
affected
adversely.
Malfunctions
may
also
result
if
the
unit
is
installed
in
a
humid
or
dusty
location.
Also
avoid
installations
next
to
kitchen
counters
or
other
places
subject
to
oily
smoke
or
heat.
ll
if
youplace
the
unit
directly
on
top
of
an
amplifier,
it
may
pick
up
humming
or
other
noise.
Also,
if
the
amplifier
generates
a
large
amount
of
heat,
the
unit
may
break
down.
™@
If
youplace
the
unit
near
a
television
set,
it
may
pick
up
noise
which
may
be
recorded
as
a
whistling
tone
on
the
tape.
In
such
a
case,
either
install
the
unit
away
from
the
television
set
or
switch
OFF
the
television
set.
DEW CONDENSATION
When
the
unit
is
moved
from
a
cold
to
a
warm
room,
or
the
temperature
changes
quickly,
condensation
will
form
on
the
mechanical
parts
and
this
will
affect
the
performance
of
the
tape.
In
such
cases,
leave
the
unit
in
a
warmer
atmosphere
for
about
one
hour
or
change
the
room
temperature
gradually.
NOTE:
When
installing
the
tape
deck,
do
not
place.a
cloth
over
the
top
or
block
the
ventilation
openings
in
any
other
way.

FEATURES
Noise Reduction Systems
Both versions (B and C) of the Dolby NR system and dbx
noise
reduction
systems
are
included
to
reduce
annoying
tape noise.
Auto Tape Selector
Detects the kind of cassette tape, and automatically sets
the recording bias and equalization.
Music Search Function
To
find
any
desired
selection
by
skipping
over
a
maximum
15 selections, forward or backward.
Timer Standby
Unattended
recording
and
wake-up
playback
can
be
performed
by
connecting
commercially-available
audio
timer.
Dolby HX Pro System
Each
deck
has
been
independently
equipped
with
the
Dolby
HX
Pro
Headroom
Extension
System,
providing
dynamic
control
of
the
recording
bias
for
a
wider
frequency
response
and
less
distortion.
NOISE
REDUCTION
SYSTEMS
This deck is equipped with three Noise Reduction systems;
the dbx, the Dolby NR B and C types.
Tape Copying Function
Tapes
can
be
easily
copied
from
deck
|
to
deck
Il,
either
at
normal or double speed.
PIONEER System Remote Control
Connect
the
CONTROL
IN
jack
to
a
component
equipped
with
the
PIONEER

(bearing
the
mark),
and
you
will
be
able
to
operate
this
component
from
the
hand-held
remote
controller
that
comes
with
the
component
connected.
(Only

can
be
operated
when
the
remote

unit
is
not
equipped
with
independent
keys
for
deck
|
and

or
when
there
is
no

@ The Dolby NR System
The
Dolby
NR
system
is
designed
to
reduce
high-
frequency
tape
hiss
noise
generated
during
playback.
The
level
of
low-volume,
high-frequency
sounds
is
increased
during
recording,
and
decreased
by
the
same
amount
during
playback
to
restore
the
original
level.
At
the
same
time,
high-frequency
noise
(the
most
easily
perceived
by
the
human
ear)
is attenuated
as
well.
Version
B
of the
Dolby
NR
system
reduces
high-frequency
tape
noise,
widening
the
dynamic
range.
Version
C
is
even
more
powerful,
applying
the
noise
reduction
effect
to
a
wider
spectrum
of
frequencies
from
the
middle
range.
™ The Dolby HX Pro Headroom Extension System
When recording audio signals on a magnetic tape, high-
frequency signals are recorded on top of each other
(recording
bias)
in
order
to
compensate
for
the
tape

depends
on
the
frequency
of
the
recorded
sound,
but
generally
it
is
fixed
to
a
value
which
gives
acceptable
results
over
the
whole
frequency
range.
The
HX
PRO
system
reads
in
the
signal
at
the
recording
head,
adjusting
recording
bias
amplitude
according
to
the
signal
condition
to
achieve
optimum
recording
characteristics.
@ dbx NR system
The
dbx
system
is
provided
to
expand
the
dynamic
range
by
encoding
and
decoding
sound
signals
across
the
entire
signal
spectrum.
During
recording,
the
input
signal
is
encoded
and
recorded
at
one-half
normal
level.
At
time
of
playback,
the
signal
recorded
at
one-half
level
is
decoded
at
twice
normal
level,
thus
returning
the
signal
to
normal.
Since
large
and
small
signals
are
decoded
in
proportion
to
their
size,
the
dynamic
range
is
greatly

The
optimum
amount
of
recording

and
tape

is
reduced.
