SPL
CABINET SETTINGS SWITCH
Switched
to Normal if being used with other ARX
SPL cabinets (eg SPL 30), but may need
switching the Phase Reverse if used with
other brands
SYSTEM PROTECT LED
This LED will
illuminate if the amplifier has encountered
a problem. Switch off AC power, wait 15
seconds, and switch back on. If the
problem was temporary, the cabinet will
now operate. If not, arrange for a service
inspection
AC POWER SWITCH and LED
This LED
illuminates when cabinet is connected to
AC Power and switched ON
SPL 32 REAR PANEL
CIRCUIT BREAKER
This will trip to protect the internals if the cabinet encounters AC power
problems. Press the RED button IN to reset. If it continues to trip, remove the cabinet from use
and arrange for checking by an authorised ARX service centre. Please don’t try to take the cabinet
apart yourself - there are
no
user-serviceable parts inside, but there
are
dangerous voltages, even
after the cabinet has been switched off and disconnected
AC POWER INPUT AND OUTPUT
The input connector is designed to receive the Neutrik
PowerCon NAC3FA. This is a fully safety approved latching ‘twist-and-lock’ AC connector. For
looping power to another SPL series cabinet, a complementary output connector, the NAC3FB, is
also provided.
WARNING MESSAGES
These could save your life and other people’s.
Please read them
carefully.
Never
put your hands inside the cabinet, even when it is switched off.
Never
fly speaker
cabinets without consulting a licensed rigger;
only
use suitably rated lifting equipment, and
never
use the handles for anything other than general handling of the SPL 32
SERIAL NUMBER
Unique to your SPL 32. Please use it in any correspondence with ARX
AC VOLTAGE
This will indicate the voltage that the cabinet is expecting to see on the AC power
connectors. Please ensure that it is correct for your area
before
plugging it in!

Setting up and using the SPL 32
The SPL 32 is very straightforward to setup and start using, but a few basic steps should
be followed.
1. Connect the signal and power cables to the SPL(s) before switching it on.
2. Connect and switch on all preceding equipment (mixer, EQs, etc) before switching
on the SPL 32(s), but make sure their level controls are pulled down. The SPL 32
will switch itself on and off silently, but will reproduce (at very high SPL!) whatever
switch-on noise or signal that is sent to it.
Each SPL 32 has a handy cable strain relief on the rear that you can
loop the power and signal cables through. This useful feature avoids
having all the weight of the cables hanging on the connectors (see pic
at left)
Flying the SPL 32
The SPL 32 is factory fitted with reinforced flying/rigging track, and
may be flown using the appropriate flying and rigging equipment. The
recessed flying track on the SPL 32 is designed to receive a double
stud spring-loaded track connector. See drawings at bottom.
IMPORTANT SAFETY NOTE
Flying speaker cabinets is
dangerous
if
done by inexperienced operators and/or
when using the wrong equipment. Ensure
all rigging is safety rated to a
minimum
of
8 x the weight of the SPL 32 (75 Kg x 8 =
600 Kgs) and is done by licensed riggers.
Flying track as fitted to cabinet
Flying hardware is available from ATM Flyware
in the USA: www.atmflyware.com Fax +1-310
