CLASS D MONOBLOCK SUBWOOFER AMPLIFIER
CONGRATULATIONS!
Thank you for purchasing the Wet Sounds Sinister TM Series amplifier. Wet
Sounds Sinister series of marine amplifiers represents the pinnacle in 12 volt
amplifier design. The Sinister™ amplifiers are the highest power to size
amplifiers anywhere in the world for marine use.
The Sinister TM amplifiers use superior performance circuitry by utilizing Wet
Sounds exclusive Class D technology combined with Wet Sounds MAXED™ Power
supply. The MAXED power supply is a patent pending technology designed to
provide high efficiency levels never thought to be achievable in a mobile
audio amplifier. What this means to you. Less current draw, less strain on the
electrical system, less generated heat. All this results in more play time!
All Sinister amplifiers feature a fully conformal coated 4 layer pcb board,
single side power, speaker and input section, and top mounted controls with
removable cover. Sinister TM amplifiers have a back lit Wet Sounds shield logo
with selectable illumination for red, white or blue that can be mounted
horizontally or vertically for flexible amplifier placement.
The Sinister TM amplifiers are not only extremely powerful but also
intelligent with a built in microprocessor controller for overvoltage
protection, undervoltage protection, DC offset and speaker short protection,
as well as thermal rollback to ensure consistent play in the harsh marine
environment. One of the most amazing aspects of the Sinister TM amplifiers
design is the efficiency rating. The SDX2500 achieves an efficiency rating at
full 4 ohm rated power of over 87%. This translates into less current draw and
less generated heat. Over twice that of a conventional class AB amplifier.
WARNING
We build all Wet Sounds™ products to play at high volumes for extended periods of time. Your ears however are not designed for high volume listening. This product can easily generate high volumes that can permanently damage your hearing. We urge you to limit your exposure to very high volume sound. You may also find your state has laws governing the volume of an audio system. Please be aware of all local and state laws in your area. A Properly tuned and operated audio system will deliver years of enjoyment when used properly.
INSTALLATION INSTRUCTIONS
Wet Sounds™ Marine Amplifiers are designed for easy installation in your boat.
To ensure proper installation of your new purchase please follow all the
suggestions listed below.
If you do not have experience with marine electrical and mechanical systems,
contact a professional installer. Paying a qualified installer is almost
always cheaper than paying a dealership to repair your boat.
LOCATING THE AMPLIFIER
The amplifier must be securely mounted to a solid surface. Please select a dry
location to mount your amplifier. All Wet Sounds products are designed to
operate in humid environments however direct contact with water can damage the
electronics. Do not mount the amplifier to any area that may have excessive
vibration (like a subwoofer enclosure). Position the amplifier in an area that
receives sufficient airflow for proper heat dissipation.
SUPPLYING ENOUGH POWER
The Laws of Nature
Your amplifier does NOT make power; it converts power, or current, from your
boats electrical system and converts it into high power musical energy. If the
amp can’t get all the power it needs it will not produce its full output. Your
Wet Sounds™ amplifier will produce full output longer than other amplifies on
the market today. Should your voltage or current drop too low the amplifier
will drop below the rated output.
Make sure your boats charging system is in good working order. Any high
performance audio amplifier will increase the demand on your alternator and
battery. If you are unsure have you charging system checked system testing by
a professional technician.
RUNNING THE WIRE CABLES
Always keep the signal cable and the power cables separated to prevent the possibility of inducing noise into the system
Carefully run the power and the signal cables through the boat. Always keep all the wire tight and tied down to prevent the power wire from shorting and reduce the risk of fire. A 1/0 AWG or larger wire should be used for power and ground connections. We recommend a fuse to be installed on the power wire within 18 inches of the battery for safety.
FEATURES
Maxed Power Supply
Wet Sounds Sinister amplifiers use a unique patent pending transformer design
we call MAXED that is the first of its kind in the mobile/marine audio market.
Making the Sinister amplifiers one of the most efficient amplifiers ever
built. Wet Sounds took it a step farther by through bolting the transformer to
the heat sink and not just the pcb, resulting in a heat sink that dissipates
heat from the output side as well as the transformer. This advanced
construction method also results in a more robust build method for the rugged
marine market.
Thermal Rollback Technology
Wet Sounds thermal rollback circuit monitors the Sinister™ amplifiers
temperature and adjusts the amplifiers output. The Sinister amplifiers are
extremely efficient. However, marine use is the most demanding application of
a 12 volt amplifier. There are times when extended listening combined with
high ambient temperatures and a tight mounting can make even the most
efficient amplifier work overtime. We designed the thermal rollback circuit to
be automatic and seamless. The amplifier will roll its peak power output so it
can lower its operating temperature. What this means for you is more play time
and not having your amplifier go into thermal protection right when they party
is going great.
Advanced Intelligent Microprocessor Control
Think of it as a tiny supercomputer constantly monitoring everything and
protecting itself from harm. The Microprocessor will put the amplifier into
protection if it senses an over voltage situation or a under voltage situation
or DC offset. If you damage a speaker or have a shorted wire. The amplifier
will also put itself into protection. And if you go past the thermal rollback
circuit, the amplifier has a second level of protection from heat and will
shut itself down.
Top mounted crossover controls
Wet Sounds designed the Sinister amplifier from the ground up as a true marine
amplifier. Marine amplifiers are mounted to amp panels in a boat. Making it
harder to access the controls. The sinister amplifiers have all the controls
on the top for easy access and adjustments once the amplifier is mounted.
Massive Four Layer PC Board.
The Sinister amplifier uses a four layer PCB to make a solid mounting platform
and robust design for the power they can produce and the rugged environment.
Remote Level Control
Remote Level Control gives you the ability to control the output level of the
SDX 2500.
Top mount back lit 3 way LED Badge Light: Red/White/Blue. Horizontal or
Vertical Placement
The Wet Sounds shield logo badge not only looks great but provides the
amplifier status through its acrylic spacer.
Two screws hold the badge onto the cover plate. With the option for horizontal
or vertical placement. This is perfect for those installations where you are
not having to re wire or change the wiring to get the amplifiers logo
straight.
Fully Balanced Inputs
Fully Balanced inputs for better sound quality with less noise.
Marine Compliant
Rubber gasket covering crossover controls designed to keep moisture away.
Conformal coated pcb for protection against moisture. Completely sealed design
for no water intrusion.
Built In Raised Feet
The sinister amplifiers were designed with integrated raised side feet. This
gives easy access to pull wire under the amplifier. This also raises the
amplifier off the boats panel or carpet allowing air to circulate.
POWER CONNECTIONS
To gain access to all connections, first remove the 4 2.5mm Allen head screws
and remove the top cover. The top cover can be replaced after all connections
and adjustments are complete.
The Sinister SDX2500 is designed for 1/0 AWG Power wire (+12 V) and Ground
wire (GND). You will need to prepare the wire by remove 5/8” on the protective
shielding on the power and ground wire. Then take a Phillips head tool and
back out the screws on the terminal block +12 volt wire into the +12V side of
the terminal block and then tighten the screw back into the terminal block.
You will do the same for the Ground wire. Please make sure you are using
“positive” wire for the +12V. Also, please make sure you are running the
ground back to the battery when used in a marine application. (in a car audio
application, make sure to ground to the chassis as close to the amp as
possible). You will also be attaching the Remote turn on. Labeled Turn ON”
This is usually a blue wire from the head unit.
SPEAKER CONNECTIONS
The combined total speaker impedance MUST NOT GO BELOW 1 OHM! Total impedance
below 1 Ohm will force the SDX2500 into protect!
You will notice that the SDX 2500 is equipped with two sets of “+” and two
sets of “-” speaker output terminals on the chassis. This is for the
installer’s convenience to accommodate multiple speaker wiring to the
SDX2500’s mono block output. These two positive and two negative connections
are connected in parallel inside the amplifier. Connecting two speakers, each
to one set of positive and negative terminals will result in a parallel
speaker connection. If only using one set of speaker wires, it is not
necessary to use both sets of speaker output terminals on the SDX2500.
Remote Level Control
The remote level control gives you the ability to control the level remotely.
You may install the level control by the driver for easy adjustments on the
fly. The Wet Sounds remote level control is not a bass boost control. Or a
remote gain. It is a remote level control. Meaning if the amplifiers gain is
set at half. The remote level allows you to turn the amplifier up remotely
from zero to half. If the amp is set at ¼. The remote level will go from zero
to ¼. This allows the system to be set at the best sounding level and just use
the remote to turn it down when needed. This is a safety feature that also
keeps people from turning your system up too high and damaging equipment
Fuses
The Sinister SDX2500 amp had Six 40 amp fuses. The Sinister amplifiers are one
of the most efficient amplifiers in the world. However, the laws of physics
apply and you need power to make power and the Sinister amps make a LOT of
power. If you blow a fuse. Check your wiring for short circuits and why the
fuse is blowing. Also, check the speakers and speaker wiring as well. You
should trouble shoot the system before replacing fuses.
MASTER/SLAVE CONFIGURATION/CONTROL SETTINGS
The SDX 2500 is equipped with a Master/Slave Circuit. This allows control of 2 or more amplifiers from 1 set of controls. All gains, crossover, bass boost, subsonic filter, and remote level will be controlled from a single “Master” SDX 2500 AmplifierThis eliminates gain/crossover matching normally needed when using multiple amplifiers.
Master/Slave
Control Settings
Use only the Crossover, Subsonic, Bass Boost, & Gain controls of the “Master”
amp. These controls will not respond on any other “Slave” amp in the chain.
SINISTER MICRO
PROCESSOR DIAGNOSTIC SYSTEM
The Sinister full range amplifiers are equipped with an advanced
microprocessor controlled diagnostic system. This system is designed to notify
you in the event the amplifier goes into protection for any reason. With a
series of LED codes, the amplifier will indicate the status to help in
troubleshooting.
Short protect and DC output protection: LED flashes for .25 seconds and off
for .25 seconds repeatedly.
Low Battery Voltage: LED flashes for 1 second and then off for .25 seconds.
High Battery Voltage: LED flashes for .25 second and then off for 1 second.
Thermal Rollback Notification:
Amp is limited to low power: LED flashes for .25 seconds and then off for 3
seconds
Amp is limited to medium power: LED ON for 3 seconds and then off for 3
seconds
Amp is limited to medium-high power: LED ON for 3 seconds and then off for .25
seconds
