Congratulations on your purchase of a LANZAR amplifier. You have purchased a quality product designed and engineered to give you many years of un compromised musical service. LANZAR amplifiers are designed with the latest technology available, incorporating a DC to DC Switching Power Supply, which provides headroom for even the most demanding peaks and dynamic ranges found on modern CD's and recordings.
MOSFET switches maintain rated power over a wide range of battery voltages PWM(Pulse-Width-Modulated) System. 2 Ohm Stable Stereo operation Stereo, Bridge Mode and Tri-Mode System Application Compatible Variable input level controls for each pair of channels Variable high and low pass crossover controls Thermal and speaker short protection circuitry Power and Protection LED indicators Bass Boost Circuitry Nickel plated power, RCA and speaker connectors High-efficiency, heavy aluminum heatsink

INPUT RCA JACKS
These inputs are for signal cables from the source. Always use high quality shielded RCA cables.
INE OUT RCA JACKS
L
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.
INPUT LEVEL CONTROL
Enables the matching of input levels to the output levels from the head unit(or other signal source).
POWER & PROTECTION INDICATORS
Provide instant information on status of amplifier, including short-circuit and thermal overload alerts.
BASS BOOST CONTROL
Increases sound level in lower frequencies by 18dB.
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 50 Hz - 500 Hz.
CROSSOVER MODE SELECTOR
Determines the mode of built-in crossover: low pass(permits only low frequency signals to pass to speakers), high pass (permits only high frequency signals to pass to speakers), or flat.
HIGH PASS FILTER
When Crossover Mode Selector is in High Pass Mode, this control limits the frequencies which will be distributed to the speakers to those above the value to which this is set within the range 50 Hz - 500 Hz.

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.
