PLAYBACK
AND
RECORDING
WITH
AV
EQUIPMENT
The
RC-870BX
permits
connection
and
switching
of
audio-
visual
components,
so
that
the
receiver
can
be
used
as an
AV
control
center.
There
are
one
set
of
inputs
for
a
stereo
AV
component
such
as
a
video
disc
player
and
one
set
of
inputs/outputs
for
a
stereo
video
recorder.
There
is
also
a
separate
TV
monitor
output
for
connection
of
a
color
monitor
for
high
quality
viewing.
This
system
then
not
only
provides
for
easy
selection
of
video
sources,
but
also
allows
high
performance
operation
for
op-
timal
sound
quality
such
as
digital
sound
from
a
Hi-Fi
video
recorder.
In
addition,
sound
track
of
video
components
can
be
dubbed
onto
a
tape
recorder
connected
to
the
receiver,
or
vice
ver-
sa.
Video
dubbing
is
also
possible
from
AV/AUX
1
to
AV/AUX
2.
Playback
To
carry
out
playback
with
the
equipment
connected
to
the
AV/AUX
inputs,
set
the
function selector
to
AV/AUX
1
or
AV/AUX
2
as
required
and
set
the
tape
monitor
selector
to
SOURCE
position.
Set
the
TV
or
video
monitor
to
the
video
input
mode
to
view
the
picture.
Adjust
the
volume
and
other
controls
on
the
receiver
to
suit
your
needs.
A
Recording
(Dubbing)
Set
the
tape
monitor
selector
to
SOURCE
position
and
func-
tion
selector
to
AV/AUX
1,
where
the
source
to
be
recorded
is
connected
Then
record
with
the
video
recorder
connected
to
the
AV/AUX
2
terminals
on
the
rear
panel.
The
video
signal
being
recorded
can
be
monitored
by
the
connected
TV
or
video
monitor.
For
advanced
applications,
such
as
combining
sound
from
an
audio
source
with
a
video
signal
and
recording
both
on
the
video
cassette
recorder
connected
to
the
AV/AUX
2
ter-
minals,
please
refer
to
the
signal
flow
table
shown
on
page
17.
(Note:
the
audio
and
video
signal
supplied
to
the
video
recorder
is
completely
unaffected
by
the
volume
and
balance
settings
of
the
receiver)
HUM
AND
NOISE
In
any
high
fidelity
installation,
hum
may
be
caused
by
the
interconnection
of
a
turntable,
tuner
and
amplifier,
and
speak-
ers
as
the
result
of
wiring,
different
grounding
or
locations
of
components.
If
hum
is
experienced
with
your
unit,
disconnect
everything
but
the
speakers
from
the
unit.
Plug
in
the
turntable
and
if
hum
or
howling
appears,
move
the
turntable
away
from
the
speakers
as
much
as
possible.
Note
hum
may
also
be
induced
by
defective
cable
connec-
tions
or
by
running
the
cables
too
close
to
strong
AC
field.
When
your
unit
picks
up
noise
during
the
reception
of
broad-
Casts,
Causes
are
mostly
due
to
external
objects
such
as
fluorescent
lamps
and
house
appliances
using
motor
or
thermostat,
or
others
that
may
induce
the
noise.
Either
relocating
the
unit
away
from
the
noise
sources
or
using
an
improved
outdoor
antenna
may
readily
solve
the
problem.
In
the
event
you
cannot
find
the
cause,
consult
your
dealer
or
a
qualified
electrician.
VOLTAGE
SELECTION
