IF
AT
FIRST
YOU
DON'T
SUCCEED
Some
suspected
defects
of
the
equipment
are
in
fact very often found
to
have arisen from faulty
operation.
Sometimes malfunctioning ancillary
equipment
which
is
connected
to
the
A2 unit
is
to
blame. Before you
consult
your
dealer
or
contact
us,
we
would
like
you
to
check
the
items
on
the
foilowing list
to
see
whet-
her
you can
correct
the
malfunction yourself.
I.
NO
MUSICAL
REPRODUCTION
IS POSSIBLE:
a)
Headphones
are
connected,
In
which case
the
other
outputs
are
switched off. Remove
the
headphones
plug.
b)
You
have
selected
MONITOR
(4).
The
display (6)
shows
"MON". Switch off
the
monitor
function.
c)
You
have selected PROCESSOR (5).
The
display (6) shows "PROC". Switch off
the
processor.
d) "Standby"
mode
unintentionaily switched
on
via
the
remote
control. Press
the
button
"On".
e)
Check
whether
one
of
the
causes given below
under
Paragraph 3.is responsible.
f)
If
the
green
LED
on
the
front
panel and
the
display
is
not
iiluminated
the
fault could be with
the
mains
fuse. This results mainly from a defect
in
the
power
transformer
or
the
amplifier electronics (eg as a
result
of
a lightning strike). Please
consult
your
dealer.

THE
AMPLIFIER
SWITCHES
OFF
DURING
OPERATION.
In
this case
one
of
the
safety circuits (overheating,
short
circuit, ultrasonic
or
DC) has functioned. This fault
will
be diagnosed
by
the
processor
and
shown
in
the
display.At
the
same
time you
will
be
requested
to
switch
off
the
amplifier with
the
onloff switch (I).
a)
If
the
word
"temp" blinks
in
the
display
proceed
as follows: switch
the
EVOLUTION A2 off (on/off switch
(I))
and wait 5 minutes. Providing
the
amplifier
works
correctly after this overheating had
occurred.
Please check
whether
the
conditions explained
in
this manual regarding
placement
and cooling have been
complied with.
b)
If
the
A2 unit switches itself off within a few
seconds
of
being switched
on
and
the
word
"overload" appe-
ars
in
the
display, a
short
circuit has
occurred
in
the
loudspeaker
cabling
or
in
the
loudspeaker itself.This
fault
must
be rectified
before
the
unit can be retaken into use. Before taking
the
unit into
reuse
it
is
to
be switched off with
the
onloff switch (I)
for
about
I minute.
c)
When
"dc"
is
shown
in
the
display it
is
the
result
of
a
direct
voltage arising.from a source, possibly defec-
tive, such as a
CD
player
etc
which disturbs
the
functioning
of
the
EVOLUTION A2.
d) Generally
these
faults can be eliminated
by
checking
that
cables
of
ancillary
equipment
are
properly
connected
and
that
the
unit
is
correctly
placed.

HUMMING
DURING
MUSICAL
REPRODUCTION.
Ground
loop through
the
aerial amplifier
or
postal cabling:
Check
if
the
humming
stops
following removal
of
the
aerial cable from
the
tuner
(and,
if
connected
to
the
A2,
the
television and video
recorder).
If
this
is
succ-
cessful fit a sheath
current
filter
to
the
aerial cables
of
these
receivers. (Your dealer
will
supply).

REMOTE
CONTROL
DOES
NOT
FUNCTION.
a)
The
remote
control
battery
is
empty.
b)
There
is
no line
of
sight
between
the
remote
control
transmitter
and
the
A2 (the transmission
of
the
signal
is
by
infra-red light).
