Connections
Using
a
Multi
‐
Channel
Preamp/Processor
with
Speakers
The
diagram
on
the
preceding
page
depicts
an
XPA
‐
5
connected
to
an
Emotiva
UMC
‐
1
Multi
‐
Channel
Processor/Preamplifier.
Your
personal
setup
may
differ,
depending
on
which
amplifier
you
own,
and
how
many
channels
you
are
using.
The
XPA
‐
5
is
simply
shown
as
a
basic
example.
The
image
shows
a
basic
5
‐
channel
surround
configuration
connecting
the
RCA/Unbalanced
outputs
on
the
processor
to
the
RCA/Unbalanced
inputs
on
the
amplifier.
Note
that
each
channel
on
the
XPA
‐
5
has
been
switched
to
‘Un
‐
Bal’
(for
an
RCA/Unbalanced
connection)
using
the
Balanced/Unbalanced
Selectors.
If
the
selector
does
not
match
the
connection
type,
the
amplifier
channel
in
question
does
not
pass
the
signal
to
the
speakers,
and
that
channel
will
remain
silent.
The
preamplifier
outputs
on
the
processor
are
labeled
as
follows:
L
(Left),
LS
(Left
Surround),
C
(Center),
LBS
(Left
Back
Surround),
R
(Right),
RS
(Right
Surround),
SW
(Subwoofer),
and
RBS
(Right
Back
Surround).
Connect
the
outputs
from
the
processor
to
the
amplifier
channels
you
wish
to
use
to
power
each
speaker.
Example:
You
plan
to
use
Channel
1
on
the
amplifier
to
power
your
front
left
speaker.
With
an
RCA/Unbalanced
cable,
connect
the
output
labeled
‘L’
to
the
unbalanced
input
on
amplifier
Channel
1.
Then,
connect
the
speaker
terminals
from
amplifier
Channel
1
to
your
front
left
speaker.
Continue
this
process
for
all
connections,
making
sure
to
keep
the
outputs,
inputs
and
speaker
terminal
connections
in
order.
If
your
processor/preamplifier
has
XLR/Balanced
outputs,
the
Balanced
inputs
on
your
X
‐
Series
amplifier
may
be
used.
Simply
switch
your
channel
selectors
to
‘Bal’,
and
use
the
XLR/Balanced
outputs
on
the
processor,
and
the
XLR/Balanced
inputs
on
each
channel
of
the
amplifier.
Surround
Speakers
Note:
In
a
standard
five
channel
configuration,
LS
(Left
Surround)
and
RS
(Right
Surround)
are
used,
and
LBS
(Left
Back
Surround)
and
RBS
9
(Right
Back
Surround)
are
left
unused.
In
a
standard
seven
channel
configuration,
LBS
and
RBS
are
included.
Subwoofer
Note:
As
seen
in
the
diagram,
the
subwoofer
output
on
the
processor
(shown
as
a
XLR/Balanced
connection)
goes
directly
to
the
subwoofer
itself.
This
assumes
that
the
subwoofer
has
its
own
amplifier.
If
the
subwoofer
has
a
separate
amplifier,
the
processor
output
would
first
go
to
the
input
of
the
amplifier,
then
to
the
subwoofer.
