Thank you for purchasing the Lanzar OPTI Class-D amplifier. Rest assured you have purchased a quality
product designed and engineered to give you many years of uncompromised musical service.
The OPTI Class-D amplifier has been designed using the latest in electronic technology available today.
This mono subwoofer amplifier is the result of advanced high speed switching technology that overcomes the
less-efficient classAB design. The OPTI Class-D amplifier reflects your true appreciation for powerful bass
reproduction in the mobile environment.
This amplifier is designed for low-frequency information only and it is not capable of reproducing any
mid/high-frequency information.
This is due to the noise introduced into the signal by the switching speed of the power supply, which must be
filtered out of the audio signal.
The power supply incorporated into OPTI amplifier is a DC to DC switching power supply designed to
have adequate headroom for even the most demanding peak and dynamic range found on today's Cds
and recording.

Low - frequency information for subwoofer only.
High efficient power
Stiffly regulated PWM power supplies.
MOSFET switches maintain rated power over a wide range of battery voltages.
Adjustable from 50Hz to 150Hz with a slope of 24dB per octave.
This allows for the adjustment of the upper point of the frequency bandwidth
and the respective subwoofer.
Adjustable from 15Hz to 40Hz with a slope of 24dB per octave.
This allows for the attenuation of frequencies that are mostly inaudible and
cause unnecessary strain on the amplifier.

1. Find a suitable location in the vehicle to mount the amplifier.
2. Make sure there is sufficient air flow around the intended mounting location.
3. Bolt the amplifier to the mounting surface.
4. Connect the power ground terminal to the nearest point on the chassis of the
car. Keep this ground wire less than one meter (39") in length. Use 4 gauge wire.
5. Connect the remote terminal to the remote output of the head unit using 14 gauge.
6. Connect an empty fuse holder within 300mm (12") of the battery and 4 gauge
or larger high
quality cable fromthis fuse to the amplifier location.
7. Make sure there is no fuse in this fuse holder. Then make the connection to the "BATT"
connection on the amplifier.
8. If multiple amplifiers are being used, use cables (each with its own fuse at the battery)
or a #0 or a #2 cable from the fuse holder at the battery to a distribution
block at or near the amplifier's location.
9. Connect all line inputs and outputs using high-quality RCA-RCA cables.
10. Insert fuse(s) at the battery fuse holder(s).
11. Recheck all connections before powering up.
12. Set all level controls to their least sensitive positions and set all crossover controls, switches,
etc. to the desired frequency or position.
13. 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 maximum output level.
14. Further fine tuning of the various controls may be necessary to obtain the desired results.

1. Line Out RCA Jacks - The LINE OUT allows you to build multiple amplifier systems
with out having to use splitter cords to distribute the signal. Now it is simple a matter of
bringing one set of RCAs into the first amplifier, then using the line out RCA jacks as the
feed to the next amplifier.
2. Input RCA Jacks -These inputs are for signal cables from the source.
Always use high quality shielded RCA cables.
3. Level Control-Enables the matching of input levels to the output levels from
the head unit(or other signal source).
4.Variable Subsonic Filter-15Hz~40Hz
6.Phase Shift control -Allows you to change the phase ofyour subwoofer from 0 to180 degrees
to help compensate for timing differences between drivers.
5.Variable Low Pass Filter-When Crossover Mode Selector is in Low Pass Mode, this control
limits the frequencies which will be distributed to the speakers to thosebelow the value
to which this is setwithin the range50~150Hz.
10.Variable Bass Boost Control- 0~18dB.

Before removing your amplifier, refer to the list below and follow the
suggested procedures. Always test the speakers and their wires first.
Check for good ground connection.
Check that remote DC terminal has at least 13.8v DC.
Check that there is battery power on the +terminal.
Check all fuses.
Check that Protection LED is not lit. If it is lit, shut off amplifier briefly
and then repower it.
Disconnect all RCA inputs to the amplifier(s)-if hiss / noise disappears, then plug
in the component driving the amplifier and unplug its inputs. If hiss / noise
disappears, go on until the faulty / noisy component is found.
It is best to set the amplifier's input level as insensitive as possible. The best
subjective S/N ratio is obtainable this way. T
ry to drive as high a signal level from the
head unit as possible.

Check for shorts on speaker leads.
Check that the volume control on the head unit is turned down low.
Remove speaker leads, and reset the amplifier. If the Protection LED still comes
on, then the amplifier is faulty.
Check that the minimum speaker impedance for that model is correct.
Check for speaker shorts.
Check that there is good airflow around the amplifier. In some applications, an
external cooling fan may be required.
Check that the Level control(s) is set to match the signal level of the head unit.
Check that all crossover frequencies have been properly set.
Check for shorts on the speaker leads.
This is always caused by a poorly-grounded RCA patch cord.
