button
switch
on
the
front
panel
of
the
phono
stage
,
while
the
right
hand
vertically
aligned
pair
is
input
2.
To
the
left
of
the
four
MC
RCA
input
connections
is
a
screw
type
connector.
This
connector
is
the
ground
connection
for
a
ground
wire
from
a
cartridge
and/or
turntable
if
you
are
using
a
moving
coil
cartridge.
To
the
right
of
the
four
MM
RCA
input
connections
is
another
screw
type
connector.
This
connector
is
the
ground
connection
for
a
ground
wire
from
a
cartridge
and/or
turntable
if
you
are
using
a
moving
magnet
cartridge.
When
you
are
facing
the
front
of
the
H
‐
1500
II
PLUS,
the
two
pairs
of
MC
connections
are
on
the
far
right
of
the
unit,
with
the
two
MM
connections
immediately
to
their
left.
The
H
‐
1500
II
PLUS
has
been
designed
and
manufactured
to
work
most
synergistically
with
Allnic
Audio
preamplifiers,
pre
‐
phono
stages
and
equalization
products.
D.
OUTPUTS
The
H
‐
1500
II
PLUS
is
equipped
with
one
pair
of
single
‐
ended
(RCA)
outputs.
The
right
and
left
channel
output
connections
are
also
aligned
vertically
under
the
label
“Output”
just
to
the
left
of
the
DC
Source
Input
(See
Figure
1),
with
the
left
channel
output
at
the
top
and
the
right
channel
output
connection
at
the
bottom.
Facing
the
front
of
the
phono
stage,
the
output
connections
are
to
the
immediate
right
of
the
power
umbilical
cord
connection.
E.
Moving
Coil
(MC)
Transformer
Controls
On
the
top
of
the
chassis,
on
the
right
if
you
are
looking
down
facing
the
front
of
the
phono
stage,
two
transformer
controls
are
accessible
through
cutouts
in
the
top
of
the
chassis.
There
is
a
control
for
each
channel.
The
“X#”
scale
corresponds
to
the
factor
that
you
will
select
for
the
millivolt
output
of
your
selected
MC
cartridge.
Each
position
on
the
X#
scale
corresponds
to
an
increase
in
gain,
indicated
on
the
+#dB
scale.
You
should
use
identical
settings
for
both
transformers
to
avoid
channel
imbalance.
Use
a
coin
or
other
appropriately
shaped
object
to
select
the
gain
factor.
We
encourage
experimentation
for
each
of
your
favourite
moving
coil
cartridges.
F.
A
NOTE
ON
PHASE
Phase
issues
generally
will
result
in
lack
of
bass
and/or
focus
of
the
stereo
image.
You
may
need
to
reverse
connections
on
your
cartridge
if
you
are
having
phase
issues.
As
is
usual
in
these
circumstances,
some
trial
and
error
experimentation
may
be
required
to
find
the
correct
position.
.
Of
course,
the
entire
process
is
simplified
if
your
preamplifier
has
a
phase
control,
as
do
the
Allnic
Audio
L
‐
1500
and
L
‐
4000
preamplifiers.
G.
IMPEDANCE
In
the
Specifications
at
the
end
of
this
manual,
you
will
read
that
the
moving
coil
(MC)
input
impedance
for
the
H
‐
1500
II
PLUS
is
up
to
117
ohms.
This
value
represents
the
internal
impedance
of
the
cartridge
itself,
and
is
at
the
extreme
upper
end
of
what
would
be
expected
for
the
internal
impedance
of
an
MC
cartridge.
It
would
be
exceptionally
unusual
to
find
a
cartridge
with
internal
impedance
greater
than
that
value.
In
fact,
however,
the
MC
step
‐
up
transformer
in
the
H
‐
1500
II
PLUS
can
accept
cartridges
with
up
to
470
ohms
internal
impedance.
INITIAL
POWER
‐
ON
Once
you
have
your
H
‐
1500
II
PLUS
in
place
and
all
connections
have
been
made
to
your
turntable
and
preamplifier,
you
are
ready
to
turn
on
the
power
for
your
H
‐
1500
II
PLUS.
Before
you
power
up
the
H
‐
1500
II
PLUS,
though,
be
sure
you
have:
•
turned
the
volume
down
or
otherwise
muted
your
preamplifier
•
pressed
the
button
switch
on
the
left
hand
side
of
the
front
panel
of
the
phono
stage,
labeled
“muting”
below
and
