INTRODUCTION...
Congratulations on your purchase of a new Lanzar Opti signal processor. Opti mobile electronics are some of the most advanced
car audio products available. These quality audio products are designed and engineered to afford you years of uncompromising
musical service. Lanzar has utilized the latest electronic technologies in order to deliver a superb listening experience.
The D-100 Active Line Driver offers the listener the ability to enjoy the finest in mobile audio. The D-100 unleashes the effortless,
natural and open quality of the real performance. Car audio systems which utilize passive crossovers feed the music through
chokes and capacitors, which creates a “bottleneck” through which the music must pass. Portions of the program material may
pass through at different speeds, creating distortion – some of the music doesn’t make it through at all!
With the Lanzar Opti D-100 you’ll hear all the dynamics in the bass, and still hear delicacies like fingers sliding across guitar
strings.

Precautions
To prevent short circuits, be sure to disconnect the negative battery ground lead before wiring the system up.
When you finish the installation, be sure to make one more check to be sure everything is done correctly.
Reinstate all car parts that were removed.
Reconnect the negative battery ground lead.

Mounting and installation
Your new Opti Series Line Driver comes complete with all required mounting hardware.
Mark the location for the mounting screw holes by positioning the Line Driver where you wish to install it
and use a scribe (or one of the mounting screws) inserted in each of the mounting holes to mark the
mounting surface. If the mounting surface is carpeted, measure the hole centers and mark with a felt tip
pen.
Before attempting to drill the mounting holes, take note of any wires, lines or other devices in your vehicle
which may be located behind the mounting surface! Then drill pilot in the mounting surface for the mounting
screws and insert then. Tighten the screws securely.
Installation
• A red 18 gauge stranded or heavier and insulated wire should be connected to the terminal marked +12V.
Wire an in-line fuse holder on this lead as it is the 12 Volts DC wire for the system. This wire should be
connected to your vehicle’s battery. If a wire is run directly to the battery make sure to install an in-line fuse
on this wire within 12” from the battery.
• A black stranded wire of at least 18 gauge should be connected to the terminal marked Ground. This is the
ground wire for the D-100 and should be attached to the same ground point with the amplifiers in the system.
Keeping this ground wire as short as possible improves the electrical circuit and keeps ground related noise
problems to a minimum.
• An orange stranded wire of a least 20 gauge should be connected to the terminal marked Remote. This wire
connects to your head unit’s remote out or power antenna lead out. This wire should supply 12 Volts DC any
time the radio, cd or cassette are playing. This lead must also be connected to any other components in your
system that utilize a remote turn-on lead for powering up.
• Connect all line inputs and outputs using high-quality RCA-RCA cables.
• Recheck all connections before powering up.
• Set all level controls to their least sensitive positions and set all Line Driver controls, switches, etc. to the
desired frequency or position.
• Once the system is powered up, set the volume control on the head unit to about the 2 o'clock position, and
then set all the amplifiers' level controls for half output level.

Noise check and system adjustment
NOISE CHECK
Check the entire audio system for noise before permanently securing the Line Driver mounting
1. Start the engine.
2. Turn the audio system on.
3. Rev the engine and vary the VOLUME of the audio system to determine if there is any unwanted noise.
If so, turn both the audio system and the engine off. Do not secure the Line Driver mounting screws. Refer to the "Trouble Shooting Guide" at this manual.
4. If the audio system does not have any noise, securely tighten the Line Driver mounting screw and double check the wiring cabl
SYSTEM ADJUSTMENT
Preliminary Adjustments
Pre-setting the system provides a necessary starting point for fine-tuning the entire audio system to maximum performance.
NOTE: DO NOT MOUNT Line Driver UNTIL THE FOLLOWING PROCEDURES HAVE BEEN COMPLETED.
1. Preset each amplifier input gain adjustment at the amplifier to half of maximum.
2. Slowly turn the volume up and listen carefully for: obvious trouble in sound (distortion, no sound, no hiss, total silence). Turn the system off refer to "Trouble Shooting
Guide" at this manual.
Caution
DO NOT ROUTE AUDIO CABLES AND POWER CABLES TOGETHER! THIS CAN CAUSE ENGINE NOISE IN YOUR AUDIO SYSTEM. ALWAYS DISCONNECT
THE SYSTEM FROM THE BATTERY BEFORE ATTEMPTING TO MAKE OR ALTER ANY CONNECTIONS. THIS PRODUCT IS DESIRED FOR USE IN ANY
12 VOLTS NEGATIVE GROUND ELECTRICAL SYSTEM ONLY. INSTALLING THIS PRODUCT IN ANY POSITIVE GROUND ELECTRICAL SYSTEM COULD
SERIOUSLY DAMAGE THE AUDIO SYSTEM.
Adjusting The Line Driver
The Line Driver provides variable enhancement of Line frequencies. The level of peak boost varies from 0 to +18dB and the frequency at which peak boost occurs is adjustable
from 40Hz to 400Hz. 20-Q to 2-Q boost characteristic can be adjustable.
2-Q characteristic boosts a wide range of frequencies and is useful for general sound quality enhancement. The 20-Q characteristic boosts a narrow range of frequencies
and can be used to tune a subwoofer system fo rmaximum output.
The Line Driver Q adjustable should be set to the 2-Q(wide) position and the frequency control set approximately one octave below the subwoofer's resonant frequency.
In vented enclosures, the roll off of the system is quite steep below the tuning frequency (typically 24dB/octave). In this case, the Line driver should be set for 20-Q(narrow)
operation. Never set the Line Driver boost frequency below a vented enclosuer's turning frequency. For maximum output from a vented enclosure, set the Line Driver boost
frequency to the tuning frequency of the enclosure. These adjustments can be made with the Line Driver in the signal path, but make sure the effect is turned off (remote
level Min.) then verify operation of the Line Driver by increasing the boost level while listening for changes in subwoofer response.
Once operation of the Line Driver is confirmed, adjustment can proceed.

TBOUBLE SHOOTING GUIDE
PROBLEM
1. There is an audible distortion at a low
volume level.
2. A whining sound can be heard through the
speakers when the audio system is at low
volume with the engine running. The whining
noise remains unchanged or seems to
disappear when the volume level is
increased.
3. There is a "motor boating" type of sound
when the engine is running and the audio
system volume is set at a reasonably high
level.
4. High squeal noise from speakers • This is almost always caused by a poorly -
• Output levels NOT set correctly.
• Check for shorts on the speaker leads.
• Check the red power wire. It muse be
connected directly to the battery.
• Check the system's ground point It muse
make good contact with chassis ground
(bare metal).
• The radio and the Line Driver must be
grounded at the same reference point.
• Check the red power wire. It must be
connected directly to the battery.
• Check the system's ground point. It must
make good contact with chassis ground
(bare metal).
