Installation
and
Connections
AC
Power
Considerations
The
majority
of
household
electrical
sockets
(in
places
other
than
the
kitchen
and
garage)
are
15
amperes
maximum,
which
is
sufficient
to
power
your
Ultra
series
amplifier.
However,
remember
to
account
for
the
electrical
power
that
other
components
will
require
if
they
share
a
common
wall
socket
or
electrical
circuit.
Most
DVD
players,
preamplifiers
and
A/V
source
units
are
fairly
low
current
items,
and
can
successfully
share
a
wall
socket
with
your
power
amplifier,
but
big
screen
TVs
and
video
projectors
usually
have
minimum
current
requirements
that
can
consume
nearly
an
entire
circuit.
Refer
to
the
owner’s
manuals
of
your
audio/video
devices
to
assess
your
electrical
power
requirements
for
your
home
entertainment
system.
If
you
have
any
questions
relating
to
issues
with
the
power
requirements
for
your
X
amplifier,

Along
with
built
‐
in
noise
filtering,
your
Ultra
Series
amplifier
is
equipped
with
overcurrent,
undercurrent,
and
spike
protection.
Upon
powering
up
your
X
amplifier
with
the
front
panel
switch
or
via
3.5mm
trigger
input
(switch
on
the
rear
panel
must
be
set
to
“ON”),
you
will
notice
the
front
panel
LED
lighting
starts
off
red
for
5
seconds
and
then
turns
to
blue.
This
indicates
the
amplifier
is
“on,”
functioning
normally
and
ready
for
operation.
If
you
do
not
see
an
LED
light
or
a
blinking
red
LED
light
while
the
amplifier
is
on
during
(otherwise)
normal
operation,
please
refer
to
the
troubleshooting
section
of
this
manual.
Physical
Placement
/Heat
Considerations
Ultra
amplifiers
employ
convection
cooling,
which
is
very
effective
and
completely
noiseless.
Under
normal
operating
conditions,
your
Ultra
amplifier
will
remain
cool
to
mildly
warm,
but
considerations
for
heat
should
be
taken
into
account
during
placement.
Place
your
amplifier
on
a
flat,
level
surface,
with
the
weight
distributed
equally
on
all
four
feet.
If
using
a
cabinet
or
shelf,
please
make
sure
that
there
is
sufficient
ventilation
and
there
is
at
least
6
inches
of
free
air
space
above
the
amplifier
and
3
inches
on
each
side.
If
adequate
ventilation
is
not
available,
your
may
consider
installing
two
small
brushless
DC
fans
(such
as
those
used
in
computer
cases)
to
provide
continuous
airflow
around
the
unit.
If
the
amplifier
is
located
on
a
carpeted
surface,
place
a
board
under
the
amplifier’s
feet.
NOTE:
Expansion
and
contraction
of
the
amplifier’s
heat
sinks
may
cause
a
faint
‘clicking’
sound
at
times.
This
is
relative
to
how
warm
the
heat
sinks
become
and
how
quickly
they
cool.
This
is
completely
normal,
and
no
cause
for
concern.
Do
NOT
block
the
ventilation
holes
on
the
amplifier.
Your
Ultra
amplifier
is
equipped
with
a
massive
toroidal
power
transformer.
This
transformer
generates
a
magnetic
field
that
could
induce
a
hum
in
a
turntable
(particularly
a
turntable
equipped
with
a
moving
coil
cartridge).
Do
NOT
place
a
turntable
directly
above
or
directly
adjacent
to
the
amplifier.
Before
placing
the
amplifier
on
a
shelf,
verify
that
the
weight
bearing
capacity
of
the
shelf
is
80
lbs
or
greater.
The
amplifier
is
heavy
and
should
be
placed
toward
the
bottom
of
an
audio
rack
to
minimize
the
rack
being
unnecessarily
top
heavy.
