CONNECTIONS

For
standard
amplifier
hookup
be
sure
the
speaker

is
set
to
"Thru

Input
Connections-
Simply
connect
the
amplifier's
"+"and"-"

directly
to

Amplifier
Impedance
load-
When
you
connect
more
than
one
loudspeaker
system
to
an
amplifier
channel,
either
by
twist
i
ng
two
wires
together
at
the
speaker
location
or
via
individual
"home

"
fr
om
the
loudspeakers
to
the

the
load
impedance
to
the
amplifier
drops.
To
find
the
maximum
number
of
8Q
speakers
that
can
be
'-:Jired
in
parallel
to
each
channel
of
your
power
amp
l
ifier,
divide
8
by
the
amplif
i

Series/Parallel-
It
is
possible
to
util
i
ze
various
series/parallel
'hook-up'
topologies
to
increase
the
number
of
loudspeakers
driven
on
an
amplifier.
See

example
of

Note:
Mismatching
the
speaker
impedance
such
that
it
is
below
the
minimum
impedance
rating
of
an
amplifier
channel
can
damage
the
amplifier
and
degrade
performance.
If
the
application
requires
more
than
2
speakers
per amplifier
channel
wired
in
parallel,
a distributed
line
system
should
be
considered.
Also
check
your
amplifier's
manual
for
cautions
and
recommendations
.
Importance
of
Correct
Polarity
("'n-Phase/Out-of-Phase")-
When
two
loudspeakers
are
wired
with
oppos
i
te
polarity
("out-of-phase")
relative
to
each
other
,
the
low
frequencies
of
the
loudspeakers
cancel
each
other,
even
though
the
speakers
are
"wo
rking
h
ard."
Trying
to
correct
the
lack
of
bass
with
an
equalizer
can
damage
your
loudspea
k
ers
-
equalization
cannot
correct
polarity
errors.
Alw
a
ys
make
sure
multiple
speakers
are
connected
in
proper
polarity.
Distributed
line
Systems
-
The
Revel
M55XC
&
MBOXC
models
come
equipped
with
built-in
7DV
/1
DOV
6DW
variable
tap
transformers
.
Utilizing
these
connections
requires
the
use
of
a
compatible
7DV/1
DOV-
capable
li
ne
voltage
amplifier.
As
with
conventionai8Q
speakers,
simply
connect
the
amplifier's
"+
"
and"_"
outputs
directly
to
the(+)
and
(-)input
terminals
on
th
e b
ack
of
t
he
enclosure.
Set
the
transformer
tap
to
your
desired
wattage
.
Unlike
conventional
8Q
speakers,
you
may
connect
as
many
XC
speakers
as
you'd
like
to
one
amplifie
r
channel
providing
that
all
the
speaker
tap
s
do
not
add
up
to
more
than
the
amplifier's
power
rating
(see
