WARNING
Your amplifier must be eanhed
at all times!
When
you
first
receive
youramplilier
il
may not have
a mains
plug
attached.
You must ensure
that
an
appropriate
plug
is used and coresponds
with the
amplifier's current
(ampere)
requirements and meets
the approval
of
your
local energy authority.
Please
refer termination of this lead
to
qualified
personnel.
Australian Monitor
takes no
responsibility for any damage
or ha]m resulting
from improper termination
of this leadl
Thewires inthe
mains lead are coloured in accordance
with the following
code:
GREEN AND YELLOW
=
EARTH
Connect to the
terminal marked with the letter
E, with
lhe EARTH SYMBOL orcoloured
cREEN.
BLUE
=
NEUTRAL
Connect to the
terminal marked with
the letler N
(or
coloured WHITE
in USA and Canada,
or coloured
BLACK in the United
Kingdom).
BROWN
=
ACTIVE
(LIVE)
Connect to the terminal
marked wilh the letterA
or L
(or
coloured BLACK
in USA and Canada or coloured
RED in the United Kingdom).
We recommend that
you provide
additionalsupportfor
the amplifier,
especially if road use is
planned,
asthe
weight
can bend some racks
otheMise. This support
can be
provided
by secure
shelving, support rails or a
rear rack mounting strip
to match upwiththe rear rack
mount
points provided
on
youramplifier.
Cooling
Each channel of
your
Al.l30OZ amplifier
is cooled by
two axialfanswhich drawcoolairfrom
the front ofthe
unit and expelthe heated airfrom the rear of the unit.
These units offer two speed fans
which run at half
speed, s/vitching tofull
speedwhenthe intemal heatsink
temperalure exceeds 600C
(1280
F).
An unrestricted airflowinto
and outfromthe unit must
be
provided.
Any restriction ofthe air flow will cause
heat to build up within the
unit and
possibly
force the
unit into its
thermal shutdown mode.
lf the unils
are lo be operated in an environment
wherethe airflow is restricted such as sealed
racks
or
even when
running 2 ohm loads, the cooling should
be supplemented by extra cooling fans to evacuate
the heated air
and aid the flow of cool airthrough the
unit.
Input Wiring
IMPORTANTI
Do not directly connec{
pin
1 on the
amplifiefs
input or strapping XLR, to the amplifier's
chassis, speaker
ground
or
power ground!
NOTE: lnput signal
ground
is not to be used as
a safety
ground
(earth).
The inputto
your
amplifi er is a balanced
3-pin
system
and requires allthree
pinsto
be connected. Only high
quality
twin-core shielded
cable should
be used.
When wiring for a balanced source the connector
going
to the input ofyour amplifiershould bewired as
follows:
Pin 2
=
HOT
(ln
Phase- non inverting).
Pin 3
=
GOLD(Reverse Phase- inverting).
Pin 1
=
GROUND/SHIELD.
When wiring from an unbalanced source
you
must
ensure that
pin
3 is connected to
pin
1
(input
ground),
either by linking the
pins
in the input connector or by
the source equipment's output wiring.
When wiring
for an unbalanced source:
Pin 2
=
HOT
(in
phasewith
the amplifier's output),
Pin3
=
GROUNDiSHIELD
(ioinsto
pin
1).
Pin 1
=

Mounting
Your amplifier is designed for standard 19" reck
mounting and
occupies
3 EIA rack units
(5.25").
The
mounting centres are:
Vertical: 2.25"
(57.15mm)
Horizontal:
1 8.1 5"
(461.
1 mm) to
1 8.62"
(473.0mm).
The slots in the mounting flange will accept bolt
diameters
upto
1/4"
(6.35mm).
