Congratulations on your purchase of a Clarus state-of-the-art power amplifier.
Your selection
of a Clarus car audio product indicates a true appreciation of fine musical reproduction?
Whether adding to an existing system or including your Clarus amplifier in a new system, you
are certain to notice immediate performance benef its.
KEEP
YOUR SALES RECEIPT
Take this time to attach your sales receipt to the manual and put in a safe place.
In case of any
unforeseen reason this product may need warranty service, your receipt will be necessary to
establish purchase date.
RECOMMENDATION
A power amplifier’s performance is only as good as its installation. Proper installation will
j
maximize the system’s overall performance. It is recommended that you have our product
installed by an authorized Profile retailer.
However, if you decide to install it yourself, please
carefully read through this manual and take your time to do aquality installation.
IMPORTANT!
Before making any connections, disconnect the car’s battery
until the installation is completed to avoid possible damage to the electrical
svstem.

WARNING!
Exposure to high power sound system con cause hearing loss or damage.
Listening to your system at loud levels while driving, will impair your ability to
hear traffic sounds and emergency vehicles. Use common sense when listening
to your system.

SAFETY PRECAUTIONS
Fuse amplifier’s power wire at the battery.
Be sure to fuse the power wire within 12” of the car’s battery. This will protect the car’s
battery in case of a short circuit between the power amplif ier and battery. THIS IS A MUST,
theamplifier’s built-infusewillonlyprotect thepoweramplifier not thecar’s battery!
Use high grade wire connectors.
To ensure maximum power transfer and secure safe connections, it is recommended to use
high grade barrier spades (for connection at amplifier) and terminal rings (for connection at
battery).
Do not run any wires underneath vehicle.
Exposed wires have a chance of being cut or damaged. It is best to run all wires through the
vehicle under the carpet and/or side panels. This lends to a cleaner installation and less risk of
damage.

Use caution when mounting amplifier .
Remember there are many electrical wires, gas lines, vacuum lines, brake lines as well as a gas
tank in the automobile. Make sure you know where they are when mounting the amplifier to
avoid puncturing lines, shorting wires or drilling holes in thegas tank.
Run signal wires away from electrical wires.
%
_)
To avoid possibility of induced noise from the car’s electrical system (i.e. popping noises or
engine noise), run wires away f rom the car’s electrical wiring.
Make all ground wires as short as possible and at the same point.
In order to reduce the chance of ground loops (i.e. engine noise), make the grounding wire as
short as possible to reduce the wire’s resistance. Also, when using multiple components, make
sureall units aregrounded at thesame point.
Avoid sharp edges when running the wires.
To avoid the possibility of power, signal or speaker shorts, be careful not to allow the
amplifiers wires to come in contact with sharp edges. Use agrommet to protect the wire when
running through thef ire wall

FEATURES
ANO BENEFITS
OC Off set Protection
This circuit protects the output of the amplifier against DC voltage.
If for some reason DC
voltage is detected at the output stage, the amplifier will shut down protecting the speakers
from direct current.
Bass Boost
For added low frequency performance the
an
bass boost 0 45Hz.

amplifiers in the system.
Short Circuit Protection
Subsonic Filter (CL1200 & CL600M On
The circuit protects the amplifier from damage due to a short found in the speakers or wiring.
If one of the speakers or its wiring comes in contact with ground, the amplifier will shut down.
To resume normal operation, correct the problem and turn the head unit off, then back on.
The
amplifier will reset and play again.
A subsonic filter has been provided to filter
audible range. Once engaged this feature help

Thermal Protection
Power Fusing
To protect the amplifier circuitry against damage caused by prolonged exposure to high
temperatures, a thermal protection circuit is activated if the amplifier reaches excessively
high operating temperature. Once the thermal circuit is activated, the amplifier will shut
down to cool off. The Amplifier will automatically turn back on once it cools down to a safe
operating temperature.
Protection Indicator
This red diagnostic L.E.D. indicates that the amplifier has gone into protection.
Once on, the
amplifier will have no output. To resume normal operation, turn head unit off and back on again.
If the amplifier immediately goes back into protection, check for high temperature, short
circuitsor low impedance.
Tri Mode Capable
If so desired the amplifier may be run in stereo and mono at the same time.
For example, this
feature would allow you to run a pair of mid and tweeters in stereo and a sub-woofer mono.
This protects the amplif ier against short circu

Bass Boost
For added low frequency performance the amplifiers are equipped with a variable O-18 dB
bass boost @ 45Hz.

One set of full range line outputs have been provided for convenient connection to additional
amplifiers in thesystem.
Subsonic Filter (CL1200 & CL6OOM Only)
A subsonic filter has been provided to filter out unwanted low bass frequencies below the
audible range.
Once engaged this feature helps to improve the amplifiers overall performance
since power is not wasted reproducing frequencies beyond the audible range.
This feature
works in conjunction with the Low-pass crossover to provide band-pass filtering.
Power Fusing
This protects the amplif ier against short circuits and excessive current.
Remote Turn-on
Automatically turns amplifier on when connected to the head unit’s remote output.
The
amplifier will turn on and off with the head unit to save current consumption.
This control also
: operates the reset circuit for the amplifier’s protection. It must be connected with the head
unit in order to reset protection circuits.

OUNTING LOCATION
Before you start the installation, it will be necessary to find a mounting location for the *
amplifier. Find a location in which the amplifier will receive adequate ventilation in order to
dissipate the heat it develops during operation.
Two popular mounting locations ore in the
trunk or under the seat.
Select the location in which you wish to mount the amplifier. Use caution when mounting
amplifier, there are many wires, gas lines, vacuum lines, brake lines as well as a gas tank in
the automobile. Make sure you know where they are when mounting the amplifier to avoid
puncturing lines, shorting wires or drilling holes in the gas tank. Once you are ready, use a
pencil to mark the mounting holes in the bottom panel. After you hove marked the locations of
the holes move amplifier out of the way and drill small starter holes to make the tapping
screws easier to install. Use provided screws to tighten down the omplif ier.
