Installing
a
new
Amplifier
PCM30a
Step
1
‐
Unbox
the
new
amplifier
(fig
1)
–
Set
the
new
amplifier
near
the
old
amplifier.
Step
2
‐
Take
a
picture
of
the
back
of
the
existing
amplifier
to
log
the
output
connections.
Step
3
‐
Remove
the
RCA
Input
connection
from
the
old
amplifier
–
Move
it
to
the
RCA
Input
of
the
new
amplifier.
This
RCA
male
‐
to
‐
male
cord
connects
to
the
Red
RCA
female
from
the
music
unit.
Step
4
‐
If
connecting
the
70v
output
to
the
new
PCM30A
amplifier,
the
far
back
right
screw
terminal
for
the
70v
will
be
the
“positive
wire,“
and
the
screw
terminal
next
to
it
will
be
the
COM
“Negative“
you
will
use.
Keep
in
mind
there
are
multiple
COMs.
You
will
need
to
use
the
COM
nearest
to
the
70v
on
the
far
back
right
side
of
the
amplifier.
Step
5
‐
Once
these
two
connections
are
complete,
and
the
input
and
output
on
the
new
amplifier
are
verified
connected,
look
for
a
Switch
on
the
back
of
the
Amp
near
the
Red/White
input.
It
must
be
switched
to
AUX
Position.
The
Front
of
the
amplifier
will
have
a
Volume
knob
labeled
MIC2/AUX.
This
volume
controls
the
input
music
to
the
speakers.
Normally
you
will
want
to
set
it
to
a
3
or
4
as
to
not
have
the
music
too
loud.
After
this
is
complete,
you
can
plug
the
power
in
on
the
amp
and
turn
the
power
button
into
the
ON
position.
–
If
you
do
not
hear
music,
you
may
need
to
adjust
the
volume
or
the
music
source
may
not
be
on
at
this
time.
