LANZAR MAX MINI MNX3000D (01) PDF SUMMARY:

How do I install 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 or 0 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 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 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.

What are the features and controls?

• Input RCA Jacks – These inputs are for signal cables from the source. Always use high quality shielded RCA cables.
• 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.
• Level Control– Enables the matching of input levels to the output levels from the head unit(or other signal source).
• Variable Subsonic Filter– 15Hz~45Hz.
• 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 those below the value to which this is set within the range50~250Hz.
• Phase Shift control – Allows you to change the phase of your subwoofer from 0 to 180 degrees to help compensate for timing differences between drivers.
• Variable Bass Boost Control– 0~18dB(45Hz FIX).
• Bass Boost Remote Control Input
• Power & Protection Indicators– Provide instant information on status of amplifier, including short-circuit and thermal overload alerts.
• Speaker Terminal

What should I do before removing my amplifier?

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. Try to drive as high a signal level from the head unit as possible.

What should I do if the amplifier will not power up?

Before removing your amplifier, refer to the list above and follow the suggested procedures. Always test the speakers and their wires first.

What should I do if there is a high hiss or engine 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 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. Try to drive as high a signal level from the head unit as possible.

What should I do if the 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.

What should I do if there is a high squeal noise from speakers?

Check that the minimum speaker impedance for that model is correct.

What should I do if the amplifier overheats and goes into protect mode?

• Check for speaker shorts.
• Check that there is good airflow around the amplifier. In some applications, an external cooling fan may be required.

What should I do if there is no or low output from the subwoofer?

• 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.

What should I do if the bass sounds distorted?

Check for shorts on the speaker leads.

What should I do if there is a thump or pop in the speakers when the amplifier turns on?

This is always caused by a poorly-grounded RCA patch cord.
