RECORD OUT hk@90V¥xi CNLY —
The left RECORD OUT positions give you the capability of
copying
between
two
VCR’s,
either
from
1
TO
2
or
2
TO
1.
The right positions are for copying between two audio tape
decks.

To
the
right
of
the
RECORD
OUT
knob
is
the
FUNCTION
(8)
selector.
It
lets
you
choose
which
sound
source
you
wish
to
listen
to.
All
settings
but
the
TUNER
are
used
to
select
inputs
from
other
separate
components
such
as
a
Compact
Disc
player
or
turntable.
Of
particular
interest
is
the
A/V
input.
This
input
allows
you
to
connect
the
stereo
or
mono
audio
output(s)
of
a
TV
tuner,
Laser
Disc
player,
MTS
adaptor
or
stereo
TV
output
into
your
hi-fi
system.
If
your
source
is
high
quality
(such
as
a Hi-Fi
VCR
or
MTS
stereo
broadcast),
and
it
is
possible
to
position
your
television
set
between
your
stereo
speakers,
the
enhanced
sound
field
will
contribute
greatly
to
your
video
enjoyment.
Note
that
all
hk880Vxi/hk990Vxi
inputs
EXCEPT
PHONO
can
be
used
for
virtually
any
line
level
playback-only
compo-
nent.
You
may
use
any
of
these
to
connect
program
sources
(such
as
an
additional
VCR
or
third
tape
deck
to
be
used
only
in
the
playback
mode).

Volumefonrol
The
extent
to
which
the
VOLUME
(9)
control
can
be
increased
is
determined
by
several
factors.
One
is
how
loud
you
listen
to
music.
Another
is
the
fact that
each
speaker
model
has
different
power
consumption
and
power
handling
characteris-
tics.
If
you
hear
audible
distortion
while
operating
the
hk880Vxi
or
hk990Vxi
at
high
sound
pressure
levels
or
when
bass
boost
has
been
added
by
the
LOUDNESS
or
BASS
controls,
reduce
the
volume
to
prevent
possible
speaker
damage.

At
the
far
lower
left
of
your
receiver
is
a
LOUDNESS
(10)
button.
It
provides
a
special
equalization
curve
which
compensaies
for
the
ear’s
decreased
bass
sensitivity
at
low
listening
levels.
When
using
your
system
for
low

engage
this

The
SUBSONIC
filter
(12)
circuit
helps
control
the
acoustic
con-
sequences
of
warped
records
and
tumtable
resonance.
If
you
can
see
your
speaker’s
woofer
cones
visibly
flutter
in
and
out
when
you
play
a
record,
subsonic
frequencies
are
present.
While
directly
inaudible,
subsonics
can
rob
amplifier
power,
cause
intermodulation
distortion
at
audible
frequencies
and
actually
damage
woofer
cones
if
the
movement
is
violent
enough.
The
hk880Vxi/hk990Vxi’s
SUBSONIC
filter
circuit
reduces
sub-bass
frequencies
at
6dB
per
octave
below
15Hz.
Audible
bass
response
will
probably
not
be
significantly
affected
by
this
action,
so
you
may
leave
this
button
pressed

whenever
you

The
MONC
button
(13)
combines
left
and
right
channel
signals
and
routes
their
sum
to
both
power
amplifier
channels.
It
has
several
purposes.
The
most
obvious
application
for
this
switch
is
with
mono
records,
such
as
old
45’s,
78’s
and
many
excellent
classical
LP’s
you
may
have
collected.
NOTE:
It
is
not
necessary
to
engage
the
Mono
button
when
listening
to
Compact
Discs
of
older
albums
which
have
retained
the
original
mono
format,
however.
Another
use
is
with
the
input
from
a
mono
VCR.
Engaging
the
MONDO
button
will
route
the
sound
to
both
left
and
right
speakers.
You
can
also
use
the
MONO
button
as
a
means
of
testing
speaker
phase
during
system
hook-up.
After
connecting
your
speakers
to
their
power
amplifier,
play
a
stereo
record
with
a
vocal
or
instrumental
that
images
in
the
center
between
the
two
speakers.
While
sitting
in
a
normal
listening
position
in
front
of
and
between
the
speakers,
have
someone
switch
the
MONO
button
on
the
hk880Vxi/hk990Vxi
in
and
out.
There
should
be
no
change
in
the
low
frequency
intensity
or
imaging
of
the
vocal
or
instrumental.
If
there
IS
a
change,
one
of
the
speakers
has
been
connected
out
of
phase,
which
results
in
poor
stereo
imaging
and
a
diminution
of
bass.
Re-check
the
polarity
of
your
speaker-to-amplifier
connections.

This
switch
activates
a
special
“loop”
which
routes
sound
out
of
the
hk880Vxi/hk990V
xi,
into
a
signal
processor
and
back
into
the
receiver.
It
can
be
used
for
equalizers,
Surround
Sound
processors,
dynamic
noise
reducers,
or
for
special
outboard
processors
required
for
certain
speaker
designs.
