Cabling.
For
optimal
sonic
performance,
you
should
use
the
highest
quality
speaker
cables
you
can
afford.
However,
common
“zip
cord”
from
a
hardware
store
can
be
employed
if
care
is
taken
to
use
the
proper
gauge.
This
will
depend
on
the
distance
from
your
receiver
to
your
speakers.
Use
the
following
chart
as
a
guide:
WIRE
LENGTH
GAUGE
OF
COPPER
WIRE
Up
to
8
ft
18
gauge
Up
to
12
ft
16
gauge
Up
to
20
ft
14
gauge
Almost
any
distance
Special
speaker
cable
Make
sure
that
both
right
and
left
speaker
wires
are
the
same
length,
even
if
the
distance
from
amp
to
each
speaker
is
different.
Also,
avoid
coiling
any
excess
wire
near
or
with
line
level
hook-up
cords,
especially
the
sensitive
cable
from
your
turntable
to
the
receiver.
Connection.
First,
determine
the
polarity
of
your
speaker
wires.
If
you
are
using
zip
cord,
they
may
1)
be
different
colors,
such
as
silver
and
copper-colored,
2)
have
a
series
of
ridges
on
one
conductor,
or
3)
include
a
strand
of
yarn
with
one
conductor.
Note
that
the
terminals
for
both
SPEAKER
SYSTEM
1
and
SPEAKER
SYSTEM
2
are
marked
LEFT
and
RIGHT
with
GND
(ground)
terminals
in
between.
A
good
practice
is
to
use
the
red/copper/ridged/yarn
conductor
for
the
RIGHT
(positive)
conductors
on
both
receiver
and
speaker
terminals.
Use
the
black/silver/non-ridged/no-yarn
conductor
for
the
GND/LEFT
(negative)
connection.
1.
Strip
1/2
inch
of
conductor
off
each
speaker
conductor.
2.
Twist
the
individual
strands
together
so
that
no
loose
strands
stick
out.
3.
Taking
care
to
maintain
proper
polarity
(positive
to
positive/
negative
to
negative),
insert
1/2"
of
conductor
into
the
hole
in
each
speaker
terminal
connector.
Remember,
even
one
loose
strand
touching
another
connector
can
cause
a
short
circuit.

If
you’re
using
two
sets
of
speakers,
repeat
these
connec-
tions
for
the
second
pair
of
loudspeakers,
using
SPEAKER
SYSTEM
2
terminals.
5.
Recheck
the
polarity
of
both
sets
of
speaker
wires,
making
sure
that
you
have
connected
“red
to
red”
and
“black
to
black”.
While
the
hk880Vxi/hk990Vxi
are
equipped
to
let
you
operate
two
sets
of
loudspeakers
at
once,
the
impedance
of
each
set
of
speakers
is
very
important.
If
you
are
intending
to
use
two
sets
of
speakers,
please
consult
APPENDIX

—
Multiple
Speakers
in
Parallel
before
proceeding
with
the
Speaker
Operating
Mode
setting.
EXTREMELY
IMPORTANT:
Setting
the
Speaker
Operating
Mode
Switch.
Both
the
hk880Vxi
and
hk990Vxi
have
a
special
selector
switch
that
optimizes
the
receiver’s
amplifier
section
for
best
operation
with
your
individual
speakers.
It
is
very
important
that
you
set
this
switch
before
playing
your
speakers.
Determining
the
impedance
of
your
speakers.
For
proper
performance,
you
must
set
the
SPEAKER
OPERATING
MODE
switch
to
correspond
with
the
impedance
load
of
your
loudspeakers.
If
you
know
the
impedance
of
your
speakers
(generally
4
or
8
ohms),
then
proceed
to
Setting
the
switch.
Tf
you
don’t
know
the
impedance
rating
of
your
speakers,
it
may
be,
A)
printed
on
the
back
of
the
speaker,
B)
noted
in
the
speaker’s
owner’s
manual,
€)
available
by
calling
your
dealer
or
the
manufacturer.
If
you
often
or
always
play
two
sets
of
speakers
at
once,
be
sure
to
use
the
combined
impedance
of
both
(see
APPENDIX
|).
Setting
the
switch.
If
your
speakers
are
rated
at
4
or
6
ohms,
set
the
SPEAKER
OPERATING
MODE
switches
to
the
left
hand
(4-ohm)
position.
If
you
have
one
pair
of
8-ohm
speakers,
set
the
switch
to
the
right
(8-ohm)
position.
Should
you
change
speakers,
or
add
extension
speakers
(which
changes
the
overall
impedance)
you
should
reset
the
Speaker
Operating
Mode
switch
at
that
time.
IMPORTANT
NOTE:
If
you
are
in
doubt,
use
the
4-ohm
position,
since
the
power
amplifier
section
of
your
receiver
runs
cooler
in
this
mode.
Overheating,
or
the
failure
of
an
internal
fuse
may
occur
if
the
8-ohm
mode
is
used
with
4-ohm
speakers.
SPECIAL
OPERATING
NOTE:
The
hk880Vxi
is
equipped
with
a
thermal
protection
circuit
that
senses
abnormally
high
internal
temperature
and
temporarily
shuts
of
the
power
output
before
it
becomes
damaged.
The
unit
will
automatically
become
fully
operational
again
as
soon
as it
cools
down,
which
may
take
60
to
90
minutes.
The
high
temperature
is
most
likely
caused
by
the
speaker
operating
mode
switch
set
in
the
“8
Q”
mode
when
it
should
be
in
the
“4
”
mode.
To
prevent
the
unit
from
overheating
again,
be
sure
to
place
this
switch
in
the
“4
Q”
mode.
Finally,
plug
in
the
hk880Vxi/hk990Vxi’s
own
power
cord
after
reading
the
warnings
at
the
beginning
of
this
manual.
We
recommend
that
your
receiver
be
plugged
directly
into
a
polarized
wall
socket.
If
you
must
use
an
extension
cord
or
power
strip,
check
that
it
is
terminated
in
a
polarized
plug
and
rated
in
excess
of
the
power
to
be
drawn
as
printed
on
the
back
panel
of
your
hk880Vxi/hk990Vxi.
