BALANCED INPUT CONNECTORS
3 pin female XLR type connectors receive the input signal -
typically from the effects rack or mixing console. Internal circuitry will AutoSum to mono if both A
and B inputs are used. Wired Pin 1 Ground, Pin 2 + (Hot) Pin 3 – (Cold)
LOOP OUTPUTS
3 pin male XLR type connector sends the signal on to another cabinet if
required. Wired the same as the input
LEVEL CONTROL
Adjusts the volume of the SPL SUB15; variable from –10 to +6 dB SPL
CABINET SETTINGS SWITCH
Switched to Normal if being used with other ARX SPL cabinets
(eg SPL 12), 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
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
poke around inside the cabinet, even when it is switched off. The SPL SUB15 is
designed for floor stacking only; no flying points are fitted. If flying is required, contact ARX directly
or your ARX distributor
SERIAL NUMBER
Unique to your SPL SUB15. 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 SUB15
The SPL SUB15 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 SUB15(s) before switching it on.
2. Connect and switch on all preceding equipment (mixer, EQs, etc) before switching
on the SPL SUB15(s), but make sure their level controls are pulled down. The SPL
SUB15 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.
Positioning the SPL SUB15
Being a Bass/Sub-Bass loudspeaker, the SPL SUB15 is non-directional in terms of Low
Frequency dispersion. To increase overall Low Frequency Sound Pressure Level,
multiple SPL SUB15 cabinets can be arrayed side by side or stacked as required
Other cabinets (eg SPL 8H cabinets) can be stand mounted on top of the SPL SUB15
Sub using the optional pole mounting kit Part # SPL-PMK-1 (see pic below left).
Note: Avoid having all the weight of the cables hanging on the connectors by tying off to
one of the handles as a strain relief.

IMPORTANT SAFETY NOTE
Flying
any
speaker cabinet is
dangerous
if done by
inexperienced operators and/or when using the wrong
equipment. Ensure all rigging is safety rated to a minimum
of 5 x the weight of the cabinet to be flown, and is done by
licensed riggers.
Do NOT fly the SPL SUB15
The SPL SUB15 is
not
fitted with any flying/rigging points, and is designed to be ground
stacked rather than flown.
Should flying the cabinet be essential,
DO NOT FIT FLYING POINTS YOURSELF
, but
contact ARX directly or your ARX distributor for details of the procedure to be followed.
See contact details on page 8.
