Introduction
Thank you for purchasing the Lanzar Heritage class-D amplifier. Rest assured you have purchased a quality product designed
and engineered to give you many years of uncompromised musical service.
The Heritage 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 class
AB design. The Heritage 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 Heritage 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.

FEATURES
CLASS-D DESIGN
Low - frequency information for subwoofer only.
High efficient power
POWER SUPPLIES
Stiffly regulated PWM power supplies
MOSFET switches maintain rated power over a wide range of battery voltages.
LOW PASS FILTER
Adjustable from 50Hz tol 50Hz with a slope of 24dB per octave.
This allows for the adjustment of the upper point of the frequency bandwidth and the respective subwoofer.
VARIABLE SUBSONIC FILTER
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.
PROTECTION CIRCUITRY
Protection against thermal, Overload and short circuit conditions.
REMOTE DASH-MOUNT GAIN CONTROL
This amplifier come complete with a compact remote GAIN CONTROLLER which can be conveniently mounted on or under the dashboard
of your car.

Features & Controls
Features & Controls
1. Line 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.
2. 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. V ariable Subsonic Filter- 15Hz~40Hz
5. L o w 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 range50~150Hz.
6. P h a s e Shift - Allows you to change the phase of your subwoofer from 0 to 180 degrees to help compensate for
timing differences between drivers.
7. B r i g d e Mode
8. B a s s Boost Remote Control Input
9. P o w e r & Protection Indicators- Provide instant information on status of amplifier, including short-circuit and thermal
overload alerts.
10.Speaker Terminals- These chrome, plated connectors can accept from 26 to 8 gauge wire. Be careful to observe proper
polarity when connecting the cables.

Installation & Precautions
Installation
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 powerground terminal to the nearest point on the chassis of the car.
Keep this ground wire less than one meter (39") in length. Use 8 gauge wire.
5. Connect the remote terminal to the remote output of the head unit using 14 gauge wire.
6. Connect an empty fuse holder within 300 mm (12") of the battery and run 8 gauge or
larger high quality cable from this 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 it's own fuse at the battery)
or a # O or #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 mVnecessary to obtain
the desired results.
Precautions
1. Before you drill or cut any holes, investigate your car’s layout very carefully.
Take care when you work near the gas tank, fuel lines, hydraulic lines and electrical
wiring.
2. Do not operate the amplifier when it is unmounted. Attach all audio system
components securely within the automobile to prevent damage, especially in an
accident.
3. Do not mount this amplifier so that the wire connections are unprotected or in a
pinched condition, or likely to be damaged by nearby objects. Be sure to select a
location inside your vehicle which has adequate ventilation.
4. Before making or breaking power connections in your system, disconnect the
vehicle battery. Confirm that your head unit or other equipment is turned off while
connecting the input jacks and speaker terminals.
5. If you need to replace the power fuse, only replace it with a fuse identical to that
supplied with the system. Using a fuse fo a different type or rating may result in damage
to your system which isn’t covered by the manufacturer’s warranty.

Troubleshooting
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 13.8V 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.
High hiss orengine noise (alternator whine) in speakers.
Disconnect all RCA inputs to the amplifier(s)-if hiss/noise disappears, then plug in the component driving the amplifier and unplug it's 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 low as possible. The best subjective S/N ratio is obtainable this way. Try to drive as high a signal level from the
• head unit as possible.
Protection LED comes on when the amplifier is powered up.
• 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.
Amplifier(s) gets very hot.
• 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 many be required.
Distorted Sound
• 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.
High squeal noise from speakers.
This is almost always caused by a poorly-grounded RCA patch cord.
