Introduction

Features
BASS DRIVER:
The CVM1 contains a Bass Driver circuit that an accurately recreates and injects Low frequency
information back into the signal path. What that means in everyday terms is that the BASS BOOSTER will give
more bass impact to your best compact discs or even your old tapes.
BASS Equalization Circuit:
The CVM1 has a unique equalization circuit that contours the restored bass to your speaker systems.
DASH MOUNT REMOTE CONTROL:
The CVM1 comes with a Dash Mountable Remote control that allows you to enjoy the effects of the
CVM1 without having to leave the driver seat. The Dash Mount Control has a LED indicator; this LED will grow
brighter as you add more bass or dimmer when you decrease it.
BASS MAXIMIZER INDICATOR:
Not only does the CVM1 provide great music to your ears, it also provides visual enjoyment as well. On
the chassis of the CVM1 there is one LED under the logo “Artconnection” that indicates the system is on.
PFM SUBSONIC FILTER SWITCH:
This unique feature is legendary in its ability to fine tune the bass response of any system, why waste
power on nasty subsonic information when PFM Subsonic Filter Switch can help you to clean things up?
BASS OUTPUT CONTROL:
The CVM1 has the ability to produce large amounts of deep, mind shattering bass without damaging
your speakers. The Bass Output Control circuit allows the CVM1 to maximize the bass output of any auto audio
system while restraining destructive bursts.

Functions
1. INPUTS: The inputs of the CVM1 use a balanced input circuit to help minimize induced noise. These are
designed to handle very high signal voltages of up to 15volts.
2. OUTPUTS: RCA connectors should be connected to the next component AFTER the CVM1 before a crossover.
3. DASH REMOTE CONTROL
4. POWER CONNECTOR
5. BASS CONTROLS: These two knobs control the Bass functions of the CVM1 SWEEP knob allows you to choose
the center frequency desired. The WIDE knob adjusts how wide of a frequency range the CVM1 will affect.
6. BASS MAXIMIZE INDICATOR: Three LED indicators flash when the bass maximization circuit is activated.
7. POWER ON LED
8. SUB VOLUME CONTROL
9. DASH SUBSONIC CONTROL: This knob control the subsonic frequency from35Hz to 80Hz.

Functions
10. INPUT GROUNDING:
In most systems, the source unit may leave this jumper set in the BALANCED position. In some
systems, the source unit may look for a ground through the RCA connectors. In this event, you should go ahead
and the change the jumpers to the UNBALANCED position.
11. GROUND ISOLATION JUMPERS:
Occasionally alternator whine may appear in a system because the source unit and amplifier may use
different grounding. To help this situation, we have provided alternattive grounding connections. Make sure your
system is turned OFF before you move these jumpers
12. BASS OUTOUT CONTROL JUMPERS:
Not all systems are designed the same, more systems are designed strictly for SPL (sound pressure
level) while others are a little more same, The Bass Maximizer circuit can either increase or decrease the signal
voltage of the Bass Restoration Circuit. Depending upon your system, you may opt to change these jumpers to a
higher or a lower setting to maximmize your bass output and protect your speakers. In most systems, the factory
setting will suit you fine. We recommend you try the factory setting first.

Electronic Connections & Wiring
POWER CONNECTION
B+)12V(: Connect a red wire to the battery or other power source.
REMORE: Connect an orange wire to remote activating (12V DC) wire of car stereo or equalizer.
GND: Connect a Black wire to the car chassis for ground connection.

Signal Connection
NOTE:
For signal connection, the output RCA connectors should be connected to the next component after the
CVM1; such as, a crossover, equalizer or amplifier. Remember, the CVM1 should go inline BEFORE a crossover.

Control & Specification
THE BASS RESPONSE IN A SYSTEM IS AFFECTED BY FOUR FACTORS:
(1) The acoustics of the vehicle
(2) The locations of the speakers
(3) The music source (CD, Tape, etc.)
(4) Speakers and speaker enclosures.
Because of the variations in the recording process, we developed CVM1 to help restore any low frequencies lost
during the recording lost during the recording process; however, the acoustics of various environments are different.
The Sweep control allows you to select a center frequency (the frequency most affected) between 27 and 63Hz.
The Width contol then allows you to control the range of the filter centered on the Sweep frequency.
The CVM1 is the most powerful bass component. This device is equipped with several different Bass Outpupt
selections. If you need change the settings, please use the chart below to determine the new setting. It
recommended that you listen to the factory setting first before changing the Bass Output setting.

If the Unit does not turn-on, and/or the power indicator LED is NOT illuminated, do this:
1) Check and make sure that B+ and GND are not reversed.
2) Check that all power wires are properly connected and have the appropriate potential (11-16 volts)
3) Check that the fuse is intact and funtioning.
If you experience high audible distortion or low output volume:
4) Check that the input and output levels are set correctly. Input should match the source and output should match
the sensitivity of the host.
5) Check the crossover settings; make sure they are correct; for a high “Q” systems, set it 1 octave or more
above.
If you experience high audible distortion or low output volume:
6) Verify that the GND connection is secure, the conductor (wire) is not too thin and unnecessarily long.
7) Check that the B+wire is not too thin and unnecessarily long.
8) Change the power source; try taking power from a different point.
