SUPERNOVA MKIV USER’S MANUAL
SAFETY FIRST
This documentation contains general safety, installation,
and operating instructions for the Supernova MKIV
subwoofer. It is important to read this user’s manual
before attempting to use this. Please pay particular
attention to the safety instructions.
Appears on the component to indicate the
presence of uninsulated, dangerous
voltage inside the enclosure - voltage that
may be sufficient to constitute a risk of
shock.
Calls attention to a procedure, practice,
condition of the like that, if not correctly
performed or adhered to, could result in
injury or death.
Calls attention to a procedure, practice,
condition of the like that, if not correctly
performed or adhered to, could result in
damage to or destruction of part or all of
the product.
NOTE:
Calls attention to information that is
essential to highlight.
IMPORTANT SAFETY INSTRUCTIONS
Read these instructions in their entirety.
Store this manual and packaging in a safe place.
Heed all warnings.
Follow instructions (do not take short cuts).
Do not use this product near water.
Clean only with a dry cloth.
Do not block any ventilation openings. Install in
accordance to the manufacturer’s instructions.
Do not install near any heat sources such as
radiators, heat registers, stoves or other
equipments that produce heat.
Do not defeat the safety purpose of the polarized
or grounding-type plug. A polarized pug has two
blades with one wider than the other. A
grounding-type plug has two blades and a third
grounding blade. The wide blade or the third
blade is provided for your safety. If the provided
plug does not fit into your outlet, consult an
electrician for replacement of the obsolete
outlet.
The Supernova MKIV is capable of generating high
sound pressure levels. You should exercise caution
when operating this subwoofer system. Long term
exposures to high levels of sound pressure will
cause permanent damage to your hearing. Sound
pressure levels exceeding 85dB can be dangerous
with constant exposure. Set your audio system to a
comfortable loudness level. The Supernova MKIV
subwoofer system is designed to generate high
levels of low frequencies (110 dB to 128 dB at 20 Hz
to 25 Hz) and this will transmit a tremendous amount
of vibration into walls, shelves and the structure;
thus causing sheet rock flexing, glass and other
objects to fall off shelves. Earthquake Sound
Corporation does not assume liability for damages
resulting from the direct use of the Supernova MKIV,
and urges users to play the Supernova MKIV in
moderate levels.
Protect the power cord from being walked on or
pinched, particularly at plugs, convenience
receptacles and the point where they exit from
the equipment.
Only use attachments and accessories specified
by the manufacturer.
Use only compatible rack or cart for final resting
position.
Unplug this product during lighting storm or
when unused for a long period of time.
Refer all servicing to qualified service personal.
Servicing is required when the product does not
operate normally, has been dropped or
damaged in any way (i.e. power supply cord or
plug is damaged, liquid has been spilled or
objects have fallen into the product, exposure to
rain or moisture, etc.).
To reduced the risk of fire or electric show, do not
expose this product to rain or moisture.

SUPERNOVA MKIV USER’S MANUAL
WHAT MAKES A SUPERNOVA? AMPLIFIER FEATURES EXPLAINED
The Supernova MKIV is a high performance power
subwoofer with a high excursion driver, the patented
SLAPS technology and a powerful 450-Watts class
“A/B” amplifier.
The active driver used in the Supernova MKIV
subwoofer is designed for accurate reproduction of bass
and sub-bass frequencies. Its motor and voice coil
structures were carefully selected to operate with
extremely low distortion and impressive transient
response, while its thermally pressed poly-ether foam
surround was chosen to allow high excursion without
any deformation.
Opposite to the active driver
is the patented SLAPS that
dr a m a t i c a l l y i n c r e a s e s
subwoofer efficiency and
capabili t y for ul tra l o w
frequency reproduction at
high decibel levels. As the
na m e in d i cates, S L APS
(Symmetrically Loaded Audio Passive System) is built
symmetrically which distinguishes it from traditional
passive radiators. It integrates identical components in
its suspension and design, ensuring the unit to move
symmetrically in both directions. It also overcomes the
limitations known from conventional closed and ported
designs that prevent radical excursion and deep
response. The unique SLAPS design allows the active
driver compression-free movement resulting in deep,
dynamic and hard-hitting bass response. Furthermore,
the pneumatic coupling of the active driver and the
SLAPS delivers revolu tiona ry resul ts both in
performance and efficiency as the SLAPS lets one
amplifier produce the output of two woofers, reducing
your power consumption and electricity bill.
The amplifier powering the Supernova MKIV is a 450Watts class “A/B” amplifier with a multitude of user
friendly features such as the auto signal detection
switch, 0 - 180º phase switch, 12dB/octave variable filter,
low level inputs and outputs, as well as high level inputs
and outputs.

Clamp style input terminal accepts high level
audio input from main or front system speakers
(up to 10 Volts). High pass filtered output
terminals designed to power up stereo satellite
speakers.

Low Level (RCA) Connection
This is the best way to drive audio signal to the
Supernova MKIV. The low level output is crossed
in high pass mode at 70Hz and designed to
connect to another amplifier to drive satellite
speakers (front or rear).
NOTE: DO NOT USE HIGH LEVEL AND LOW
LEVEL INPUT AT THE SAME TIME

Auto Sensing Power Switch
When ON, the amplifier will stay on regardless of
signal existence. If set on AUTO, the amplifier will
automatically turn on when audio signal is
detected. In this setting, the amplifier will also
automatically turn off after 30 minutes if no signal
is detected. When OFF, the amplifier will remain
off even when the main power switch is in the ON
position.

0 - 180° phase switch to correct the sub’s phase
with respect to the satellite speakers. Note that
maximum bass is only achieved when the sub is in
phase with the rest of the speakers in your
system.
