Troubleshooting
Guide
Ultra
Series
amplifiers
are
expertly
designed
and
built
to
provide
years
of
trouble
‐
free
performance.
Most
problems
that
occur
can
usually
be
solved
by
checking
your
setup
or
making
sure
that
the
audio
and
video
components
connected
to
the
amplifier
are
on
and
fully
operational.
NOTE:
Before
turning
on
your
amplifier
for
the
first
time,
be
sure
to
check:
1.
The
Balanced/Unbalanced
selectors
for
each
amplifier
channel
(located
on
the
back
panel).
If
the
selection
does
not
match
the
connection,
the
channel
will
not
work.
Make
sure
that
you
are
selecting
the
proper
type
of
connection
for
the
cables
you
are
using.
2.
The
status
and
meter
LED
selectors
on
the
back
panel.
If
these
are
in
the
‘off’
position,
the
status
and
meter
LEDs
will
not
light.
The
following
information
will
help
you
deal
with
other
common
setup
problems
you
may
experience
during
normal
use
of
your
unit.
If
problems
persist,
contact
Emotiva
support
for
help.
No
Sound
(from
one
or
more
speakers
connected
to
the
amplifier)
•
Speaker
cables
may
have
come
undone.
Turn
off
your
system
and
check
the
cables,
tighten
the
amplifier
and
speaker
binding
posts.
•
Damaged
audio
cable.
•
The
preamplifier
volume
level
is
low
for
the
channels
concerned.
Recheck
the
preamplifier
calibration
procedure.
•
A
preamplifier
Mute
switch
may
be
on,
an
external
processor
loop
or
a
tape
monitor
loop
is
engaged.
•
Check
that
your
preamplifier
or
source
is
running
the
correct
surround
mode.
Maybe
it
is
set
for
2
‐
channel
stereo
when
you
were
expecting
5.1
surround
sound.
•
Check
if
any
missing
channels
have
been
turned
off
in
a
preamplifier
setup
menu.
For
example,
the
center
amplifier
channel
will
not
receive
a
signal
if
the
preamplifier
has
been
set
to
“Phantom”.
•
Check
main
power
switch
to
make
sure
that
it
is
in
on
position
(1).
•
An
internal
fuse
on
the
unit
may
have
blown.
Contact
Emotiva
Support
for
assistance.
The
amplifier
shuts
down
often
or
the
line
circuit
breaker
trips
often
•
Check
that
the
positive
and
negative
speaker
wires
are
not
shorted
together.
•
Make
sure
that
no
speakers
are
shorted
internally.
If
you
have
an
ohm
‐
meter,
disconnect
the
speaker
wires
and
measure
the
resistance
between
the
speaker’s
positive
and
negative
terminals.
•
Measure
all
speakers
and
check
their
impedance
specifications.
If
necessary,
review
the
“Series
and
Parallel
Connections”
section
in
this
manual.
•
If
you
have
connected
speakers
in
parallel,
the
overall
impedance
may
be
too
low.
It
is
recommended
that
you
rearrange
the
speakers
in
series
to
increase
the
overall
impedance,
thus
taking
some
load
off
the
amplifier.
•
Make
sure
the
amplifier
has
good
ventilation
and
is
not
overheating.
Allow
good
airflow
underneath
wherever
possible.
If
the
amplifier
is
in
a
closed
rack,
open
up
the
rear
panel
or
use
a
quiet
fan
for
improved
ventilation.
