sources
output
and
their
facilities
with
regard
to
phase,
you
may
want
to
switch
to
inverted
phase
sometimes.
Phase
issues
generally
will
result
in
lack
of
bass
and/or
focus
of
the
stereo
image.
REMOTE
CONTROL
The
remote
control
provides
the
ability
to
remotely:
Power
the
L
‐
1500
on
and
off
(it
is
a
“toggle”
type
switch)
using
the
button
labeled
“POWER”.
Select
the
line
source
input
using
either
the
numbered
buttons
or
the
up
and
down
arrow
buttons
above
and
below
the
CHANNEL
label.
•
Control
the
volume
level
using
the
up
(louder)
and
down
(quieter)
arrow
buttons
above
and
below
the
VOLUME
label.
•
Mute
the
volume
using
the
button
labeled
MUTE,
located
between
the
CHANNEL
and
VOLUME
arrow
buttons.
Depressing
this
MUTE
button
will
run
the
volume
control
down
to
zero.
To
raise
the
volume
again
after
muting,
press
the
MUTE
button
to
take
the
volume
level
to
where
it
was
prior
to
muting.
INITIAL
POWER
‐
ON
Once
you
have
your
L
‐
1500
in
place,
all
connections
have
been
made
to
your
sources
and
your
stereo
amplifier
or
mono
‐
blocks
and/or
subwoofer(s),
press
the
power
switch
on
the
rear
panel
of
the
chassis
to
the
“on”
position
–
that
means
the
switch
is
“down”
at
the
top.
PLEASE
NOTE
–
CAUTION!
1)
You
may
need
to
depress
the
power
switch
on
the
rear
of
the
chassis
several
times
(wait
30
seconds
or
so
between
each
try),
for
the
L
‐
1500
to
power
up
internally
(before
you
turn
on
the
unit
from
the
front
panel
or
the
remote
control).
The
boot
system
inside
the
unit
needs
to
recognize
the
remote
control
and
synchronize
with
it;
this
is
what
accounts
for
the
possible
necessity
of
several
tries
with
the
rear
switch.
When
that
operation
is
successful,
the
events
described
just
above
will
occur.
Unsuccessful
boot
‐
ups
may
result
in
some
of
the
front
LED’s
glowing
faintly
if
the
power
switch
on
the
front
panel
of
the
chassis
is
in
the
“on”
position,
but
this
may
be
ignored.
2)
Be
sure
you
have
manually
turned
the
volume
control
on
the
front
panel
to
the
extreme
counter
‐
clockwise
position
(minimum
volume).
OPERATION
When
the
Allnic
L
‐
1500
has
powered
up
internally
and
you
have
either
depressed
the
far
left
hand
button
marked
“power”
on
the
front
panel,
or
pressed
the
power
button
on
the
remote
control,
the
following
will
happen
on
the
front
panel:
The
light
above
the
“power”
button
will
illuminate.
The
meter
on
the
far
left
hand
of
the
front
panel,
labeled
“current”
will
illuminate.
Any
of
the
five
numbered
line
source
lights
that
are
depressed
will
illuminate.
After
about
forty
(40)
seconds,
the
light
above
the
“operate”/”mute”
button
will
illuminate.
The
L
‐
1500
has
a
“soft
start”
delay
for
the
tubes
in
order
to
extend
tube
life.
The
Allnic
Audio
L
‐
1500
is
now
ready
for
operation.
At
this
point,
you
can
power
on
your
stereo
power
amplifier
or
mono
‐
blocks.
To
avoid
surges
to
the
speakers,
it
is
best
to
change
from
input
to
input
only
with
the
“operate”
button
set
to
mute
(the
light
above
the
button
will
not
be
illuminated
when
the
button
is
in
the
“mute”
position).
From
this
point
on,
operation
is
straight
‐
forward.
All
functions
are
controlled
from
the
front
panel
or
the
remote
control.
Of
course,
BE
CAREFUL
about
differences
in
gain
between
your
sources.
Generally,
disc
players
and
tuners
will
have
greater
gain
than
phono
‐
stages.
That
means
the
volume
setting
for
listening
to
your
turntable
might
be
too
high
for
listening
to
CD’s.
When
you
are
finished
listening,
turn
off
your
stereo
power
amplifier
or
mono
‐
block
amplifiers.
Then
turn
off
the
L
‐
1500,
using
the
remote
control
or
depressing
the
power
switch
on
the
front
panel.
The
power
switch
on
the
rear
panel
should
stay
in
the
“on”
position
–
this
will
keep
key
circuitry
warm,
and
your
L
‐
1500
will
be
ready
to
play
when
the
soft
‐
start
turns
on
the
L
‐
1500
next
time
you
want
to
listen.
Turn
off
your
sources
last.
