INTRODUCTION
Thank you for purchasing the Lanzar MAX P- PRG series amplifier. Rest assured you have purchased a quality
product designed and engineered to g. e you many years of uncompromised musical service.
The MAXP
PRO series amplifier has been desigrned using the latest in electronic technology available today
This mono subwooferamplifer is the result of advanced highspeed switching technologythat overcomes the
less-efficient classAB design. The MAxP PRO series amplifier reflects your true appreciation for powerful bass
reproduction in the mobilee virol7lment.
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 intreXluced intothesignal by theswitching speed of the power supply, which mustbe
filtered
out of the audio Signal.

I. Une Out RCA Jacks· The LINE OUT allows you to build multiple amplifier systems
without 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.
Z. Line Input RCA.Jacks-These inputs are for signal cables from the source.
Always use high quality shielded RCA cables.
3. Input Level Controls· Enables the matching of input levels to the output levels
from the head unit! or other signal source).
4. Phase Shift· Allows you to change the phase of your subwoofer from 0 to 180
degrees to help compensate for timing differences between drivers.
Amplifier Feature Descriptions:
BAlANCED INPUT:Accepts balanced line inputs from 0.4 volts to 18 volts.
LINE INPUT: The Line Inputs are the RCA inputjacks labeled "LINE INPUr. This is where
the Radio/CD player RCA outputs connect to. The line Inputsaccept unbalanced RCA inputs
from 0.2 volts to 9 volts.
UNE OUTPUT: The Line Outputs are a directpass·through from the inputs. The RCA input
signal from the radio/CD player is routed through the amplifierand out of the Line Outputs.
The outputs would connect to another amp Line Inputs in a multi-ampset-up. This allows you to
daisy chain multiple amps from a single set of RCA cables from the radio/CD player.
LEVEL: The input level control allows you to match the amplifier input sensitivity to the
output level of the RADIO/CD player from 0.2 Volts to 9 volts when using unbalanced RCA
cables. The level control needs to be adjusted to match the line level Sensitivity fthis is the
amount of voltage the radio/CD player RCA's provide. Example: If the radio/CDplayer Line
level Sensitivity is 4 volts, adjust the amp level control to 4 volts
SUBSONIC: Thevariable SubsoniC filter is for subwoofer applications that require very low
tuning frequencies typically around 15Hz-35Hz.
BASS EQ: Variable Bass Boost from 0 to 1 OdB at a fIXed 45Hz.
LOW PASS: Fully adjustable crossover from 35 to 250Hz.

6. Variable Bass Boost Control· 0 - +10dB
7. Variable Subsonic Filter· 15Hz-35Hz
8. 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 those below the
value to which this is set within the range 35Hz-250Hz.
9.Power & Protection Indicator .. Provde instant information on status of amplifier,
including short-circuit and thermal overload alerts.
10. Balanced input: Accepts line level balanced input from 0.4v to 18v.
PHASE SHIFT: The Phase Shift is fullyadjustable from 0 to 180 degrees and this allows you to
control the timing of the subwoofers. This is commonly used when the subwoofers are installed
in each
front door.
SYSTEM DIAGNOSnCS: The amplifierhas built-in monitoring devices and protection
circuits that monitor all vital functions of the amplifier. The Protection light does not come on
to indicate there is a failure, it comes on when it detects an improper operation. Common
issues that cause.
Protection status are:
- THERMAL: The amp has an internal temperature sensor that will automatically shut off the
amp if it reaches dangerous temperature levels.
- OVER LOAD: If the amp is run at an improper impedance, the amp will shut down. If you are
-CUPPING- speakers/ subwooferfsJ, the light will blink to indicatea hard Clip.
• DC PROTECT:In the unlikelyevent the amp should internallyfail, the amp will shut down
to prevent a DC voltage output to the speakers or sub.
REMOTE: The Remote Module plugs into the Remotejack and allows you to adjust
the level.

SETTING UP SYSTEMS AFTER INSTALLATION FOR BEST PERFORMANCE
General:
At this point you are ready to get more specific on the settings for your amplifier.
Subsonic:
This setting acts as a low frequency cut off for your system bass reproduction. The point that you set it at cuts off any frequencies from reproduction
beyond this point. The
12 o'clock position is a greatstarting point. EXAMPLE: If you adjust the Subsonic to 25Hz, the amplifier will not playfrequencies
below 25Hz but will playfrequencies from 25Hz to the chosen Low Pass frequency.
8assEQ:
This setting is a fixed bass boost at 45Hz that is variable from 0-I OdB. This feature provides impact to your bass, but if not adjusted correctly, it can be
over used
and cause damage to your subwoofers and amplifiers. It is best to slowly turn this setting clockwise until the desired punch is felt. it is not
recommended to exceed the 12 o'clock position unless listening at a low volume or a low recording quality as this can result in high distortion and
possiblyclipping.
Low Pass:
The Low pass control acts as a ceiling and doesn't allow frequencies to the right of the desired setting to be reproduced. The 12 o'clock position is a
greatstarting point.
EXAMPLE: If you adjust the Low Pass to BOHz, the amplifier will not playfrequencies above 80Hz but will playfrequencies from
80Hz to the chosen Subsonic frequency.
Phase:
The variable Phase adjustmentallows you to change the relative time that the waveform meets your ear. With standard subwoofer installations where
the subwoofer is behindyou, the Phase should generallybe at O. When subwoofers or woofers are in the kick panels or door panels, the Phase
adjustment is useful in delaying the timing of the wave meeting your ear by adjusting the potentiometer to I BO degrees.
LeveIIGAlNJ Control Setup:
Ensure that the Level is turned completely to the left prior to turning the system on. Next you should inserta CD or cassette that you arefamiliar with
to use as a reference, and turn the head unit volume control to about 80% of its full setting. The system sound level will of course beverylow, and the
following procedures will help you to match the amplifier input sensitivities properly to the head unit output signal level. It is important to match the
amplifierLEVEL input sensitivity to the Radio/CD output sensitivity. This can be located in the Radio/CD manual. If the Radio/CD output sensitivity is
2 volts, then adjust the amplifierLEVEL input to 2 volts.
If you are not sure what the Radio output sensitivity is, follow these general guide lines:
Turn
the level control up slowly, till you hear distortion, then back off a few degrees on the control. If at any point your amplifiergoes into protection,
you will need to turn the Level to the lefta bit and then tryagain. If you reach a point where the output does not increase, stop turning the Level
control
to the right as the amplifier/subwoofercombo has reached its maxx output in this application.

TROUBLESHOOTING
Before removing your amplifier, refer to the list below and follow the suggested procedures. Always test the speakers and their wires first.
AMPLIFIER WILL NOT POWER UP.
Check for good ground connection.
Check that remote DC terminal has at least 13.Bv 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 amplifierbriefly and then repower it.
HIGH HISS OR ENGINE NOISE (ALTERNATOR WHINE) IN SPEAKERS.
Disconnect all RCA inputstothe amplifierlsJ.jf hiss/noise disappear>. thenplug in thecomponentdriving theamplifierand unplug its inputs. If hiss / noise
disappear>. go on until thefaulty/noisycomponent is found.
It is best to set the amplifier's input level as insensitive as possible. The best SUbjective SIN ratio is oblainablethis way. Tryto drive as high a signal level
from thehead unit as possible.
PROTECTION LED COMES ON WHEN tT HE AMPLIFIER IS POWERED UP.
Check for shorts on speaker leads.
Check
that the volume control on the heiJd unit is turned down low.
Remove speaker leads.
and reset the am/Jlifier. If the P otection LED still comes on. then the amplifier is faulty.
Check that the minimum speaker imped<lnce 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 maybe required.
DISTORTED SOUND
Check that the level contrails) is set to match the signal Ie
Check
that all crossover frequencies have been properly set.
