4. POWER INDICATOR
This indicator lights up when the internal switching power supply is activated
and the unit is operational.
5. LEFT/RIGHT HIGH IMPEDANCE INPUT
To be connected to output of source unit.
6. LEFT/RIGHIT LOW IMPEDANCE INPUT
If RCA output is not available, connect speaker outputs of signal source to this
input.
7. HIGH-PASS FREQUENCY SELECTOR
For selection of high-pass crossover frequency between All Pass, 80Hz, 100Hz
and 125Hz.
8. HIGH-PASS FILTER SLOPE SELECTOR
6 dB: When the high pass crossover frequency is set close to the speaker's
resonant frequency, where the response rolls o at a rate of 12 dB per octave,
switching the selector to the “6 dB” position would produce the ideal 18 dB
odd order type phase response.
18 dB: When the crossover frequency is set away from the speaker's resonant
frequency, switch the selector to the “18 dB” position for ideal 18 dB odd order
type phase response.
9. HIGH-PASS OUTPUT LEVEL CONTROL
For adjusting the high-pass output signal level.
10. LEFT/RIGHT HIGH-PASS OUTPUT TERMINALS
To be connected to the mid/tweeter amplier left/right inputs.
11. LOW-PASS FREQUENCY SELECTOR
For selection of the low-pass crossover frequency between 50 Hz, 63 Hz,
80Hz and 100 Hz.
12. LOW-PASS OUTPUT LEVEL CONTROL
For adjusting the low-pass output signal level.
13. LEFT/RIGHT LOW-PASS OUTPUT TERMINALS

INSTALLATIONS
CAUTIONS: Please follow all the installation recommendations and instructions
in this manual, Installing and for using the electronic crossover in methods other
than those outlined herein may reduce the performance capability of the crossover.
Any such installation or usage may render the product warranty void.
A. LOCATION
1. Select a mounting location that is easily and conveniently accessible, e.g.
inside the trunk.
2. To avoid damage to the crossover, keep the crossover away from any heat
source (such as the engine or any heat- generating ducts).
3. There should be adequate clearance above the crossover to allow easy
adjustment.
B. WIRING LAYOUT
Once the location of all the components has been determined, plan the best
routes for all the necessary wiring, making sure that the wires are easily
accessible without dismounting the various components.
CAUTIONS: Routing audio cables and power cables together would invariably
cause radiated engine noise in your audio system. If possible, run audio cables on
one side of your car and power cables on the other. Never route these wires
underneath the vehicle body.
1. Check and make sure the vehicle s main battery and/or auxiliary battery, if any,
is/are in good working condition and has sucient capacity to run the electrical
components of the vehicle plus the complete audio system.
2. The crossover is designed for use in 12 volt NEGATIVE GROUND electrical
system ONLY. Installing the crossover in a vehicle with positive ground electrical
system could result in serious damage to the electronic crossover, other audio
components and/or the vehicle s electrical components.
3. FOR SAFETY, DISCONNECT THE BATTERY GROUND BEFORE INSTALLATION.

C. MOUNTING
1. Place the crossover at the desired location and use it as a template to
determine the exact position of the mounting holes. Mark the mounting
holes with a pen.
2. Use a center punch to ensure drilling the exact position for the screws.
Drill four (4) 1/8 pilot holes. DO NOT BEGIN DRILLING UNTIL YOU HAVE
PUT THE CROSSOVER ASIDE. USING THE CROSSOVER AS DRILLING
GUIDE MAY CAUSE IRREPAPABLE DAMAGE TO THE COROSSOVER.
3. Mount the unit with the Philips head sheet metal screws and steel washers
provided.
D. WIRING
1. Run the various wires according to your wiring layout, avoiding sharp edges
and door jams.
2. Electrical tape or grommets should be used to protect the wires when they
are routed through bare metal holes.
Note:
The battery ground should remain DISCONNECTED at all stages of installation.
E. CONNECTIONS
1. Connect the crossover to the Source Unit
Connect the outputs of the source unit to the inputs of the crossover (either
via the low impedance input or the high impedance input).
2. Connect the crossover to the Ampliers
Connect the high-pass and low-pass outputs of the crossover to the inputs
of their respective ampliers.
3. Connect the Ampliers to the Speakers
Connect the various ampliers to their speakers following the amplier's
manual and specications.
4. Connect the crossover to the Battery
Connect the power input cable to the positive terminal of the battery.
Add circuit breaker to any power wire that runs through rewall or sheet
metal to protect the battery, the vehicle, and more importantly, you.

5. Ground Connection
Connect the ground input cable of the crossover to the vehicle chassis.
For better conductivity. If necessary, scrape paint o the chassis to reveal
bare metal at the contact point.
6. Connect the Remote Input Terminal of the crossover to the Source Unit
Connect the remote input cable of the crossover to the remote output
terminal of the source unit to establish crossover remote power on/o via
the source unit. If the source unit does not provide a remote output, connect
to its power antenna terminal or other switched 12-volt source, e.g. Ignition
switch.
7. Reconnect the Battery Ground to the Vehicle Chassis
Double check all the previous installation steps with the following table.
If everything is in order, complete the installation by reconnecting the
battery ground to the vehicle chassis.

System Check
A. PRELIMINARY ADJUSTMENT
1. Pre Setting
a. Preset high-pass and low-pass amplier input gain to half of their maximum.
b. Preset the crossover frequencies and output levels as follows:
High-Pass Frequency Selector: 125 Hz
Low-Pass Frequency Selector: 100 Hz
High-Pass Output Level: 10 o'clock position
Low-Pass Output Level: 10 o'clock position
c. Preset the volume of the source unit to its minimum (otherwise, when the
source unit is turned on, the sudden surge of high power from the
ampliers might cause damage to the audio components).
2. Turn the source unit on and slowly turn the source unit volume up:
a. No Sound At All
• Turn the system o immediately.
• Check if connections are made properly
(refer to sub-section titled CONNECTION for details).
• Use a Volt/Ohm meter to make sure good chassis ground established for
each component that needs to be grounded.
• Check if the power input of all system components are properly connected
to 12 volt positive power supply.
• Check if the remote on/o terminal of all system components are properly
connected to positive 12-volt source.
• If everything is in order, turn the power on again. If the problem persists,
refer to section titled TROUBLESHOOTING for assistance.
b. Obvious Distortion
Turn the system o and refer to section titled TROUBLESHOOTING for
assistance.
c. Out-of-Phase Problem (Abnormal Bass) Turn the system o and refer to
section titled TROUBLESHOOTING for assistance. If none of the above
problems exists, proceed to the next step.

B. CROSSOVER FREQUENCY ADJUSTMENT
When setting the crossover frequencies, it is best to use compact discs or
cassette tapes with greater dynamic range. Usually home recorded tapes are
better in this respect than commercially recorded tapes.
System Check
1. Center the tone, balance and fader controls of the source unit (leaving the
other controls at their previous positions).
2. Set the volume of the source unit to approximately 2/3 of its maximum output.
3. Low-Pass Crossover Frequency Setting: Starting from 100 Hz, listen to the
bass sound quality, if the bass is “Boomy" or soft sounding, select the low-pass
frequency to other positions (80/63/50 Hz) until the bass sounds tight and deep.
It is all a matter of personal preference. The optimum setting varies from vehicle
to vehicle and from individual to individual. Subwoofer crossover frequency
setting of as low as 80Hz is not uncommon.
4. High-Pass Crossover Frequency Setting: Starting from 125Hz, adjust the
high-pass frequency until you get your desired sound quality. Again, there is no
universal optimum setting. It depends on the size and location of the front
speakers and also your personal preference.
C. OUTPUT LEVEL ADJUSTMENT
As in the case of crossover frequency adjustment, when making the output
level adjustment it is best to use compact discs or cassette tapes with greater
dynamic range.
1. Center the tone, balance and fader controls of the source unit (leaving the
other controls at their previous positions).
2. Set the volume of the source unit to approximately 2/3 of its maximum
output.
3. With each of the crossover level controls, turn the level up or down until
distortion develops, then retrace the path until distortion disappears.
4. Optimum output levels vary with the program source (radio, tape or CD).
If the optimum output levels for radio dier considerable from those for
tape/CD, locate the median levels that are best for both program sources.
