Introduction
Welcome to the Arc Audio family of performance signal processors. A blend of
Arc Audio's lengthy experience in performance car audio design combined with
our highly skilled engineering staff. You are now the proud owner of the KEQ7. A
unique combination of the highest quality components and precision
engineering. Whether you are a competitor or simply enjoy faithfully reproduced
music, you will definitely appreciate how these products make your system
sound. Before you begin read this manual cover to cover (does anyone ever
really do that?). Careful design and layout of your system and following the
instructions and suggestion in this manual will greatly simplify installation of
this product. If at any point you begin to feel overwhelmed, return to your local
Arc Audio dealer and let the trained professionals install or tune it for you.
Warning
We build all ARC Audio 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 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 in a car. Please be aware of all local and state laws in you area.
A properly tuned and operated audio system will deliver years of enjoyment
when used properly.
Warning
Please check the suitability of the installation location before you begin. Do not cut
any of the car’s structure. Pay close attention to what is behind the panels or carpet.
Often the manufacture will hide wires, computers or other electronic devices in the
exact areas you wish to install in.
If you do not have experience with automotive electrical and mechanical systems
contact a professional installer. Paying a qualified installer is almost always cheaper
then paying a dealership to repair your car.
Running the Cables
Carefully run the power and signal cables through the passenger compartment
of the vehicle. Always use a rubber grommet to prevent the power wire from
shorting and to reduce the risk of fire.

Installation Information
1. The KEQ 7 needs to be installed in the signal path between your source unit
and your external amplifier(s).
2. Physically mount the KEQ 7 near the drivers listening position. Make sure the
EQ is kept clean, cool, and dry. Don't mount it under a cup holder or in a storage
box were it will be covered with the stuff that always seems to collect in our
cars.
3. Hook up +12 volt power, ground, and remote turn-on. Make sure the ground is
perfectly clean and tight. Remove all the paint and under coat before you screw
it down. Don't trust the stock ground. Make a new one.
4. Connect the front output of you head unit to the front input of the KEQ 7.
5. Don't fix the EQ permanently into place until your gains have been set.
6. Adjust the "Input Level" control on your KEQ 7 to match the source unit's
output. With the head unit volume at about 75% of Max, adjust the gain control
slowly up until you begin to hear clipping or distortion. Now turn the gain down
slightly. This is your final gain setting.
7. Now the fun begins. With the EQ still out, begin adjusting the sub crossover.
Select the switch up and down and try to determine the best setting.
8. Now start tweaking the EQ controls. It's amazing how much a tiny adjustment
to your EQ frequency can change your system.
9. Enjoy the results

Sub Output: Connect to your Subwoofer amp or amps.
Sub Frequency Control: Be sure to make your final adjustments to the Sub
crossover before you mount the unit into the dash of your car. You will need to
complete your tuning first.
DVD Input: Connect any extra source to this input. Its very useful for MP3 players
as well as DVD or Game consoles.
DVD Gain: The DVD gain is used to match the level of your main input.
Input: Main Input should be a full range signal from the head unit. If you are
using the Sub Direct Input the signal could be crossover but the EQ will function
better if you feed it a full range signal.
Rear Output: Just like it sounds, this is connected to the rear amp.
Front Output: Simply connect to the amplifier driving the front speakers. This is a
full range output so if you plan to run it hard you should use a crossover at this
point.
Power Connector: 12 Volt +, Remote and Ground. We recommend using a
dedicated 12 Volt+ from the battery and a fresh ground. Remember this EQ has
an volt output. It takes a good amount of current to run.
Sub Volume: Or Sub Out level, gives you total control of the Sub Gain at any
time.
Master Volume: Controls all Output including the "Sub Out". It is very handy to
have one volume under your thumb for "Fast" and easy control.
DVD Input Selector: When this button is pushed in the KEQ 7 will take its input
from the DVD input. If you have nothing connected to this input you will have no
output.
Fader: Full front/rear control to keep the people in the back seat happy.
EQ Frequency Controls: If you know what an EQ does, you most likely know
what these do. We've crammed 7 bands into the KEQ 7, for ultimate control at
your fingertips.
