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.

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.
LOW 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.
HIGH PASS FILTER
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.
CROSSOVER MODE SELECTOR
Provide instant information on status of amplifier,
including short-circuit and thermal overload alerts.
POWER & PROTECTION INDICATORS
Enables the matching of input
levels to the output levels from
the head unit(or other signal
source).
INPUT LEVEL CONTROL
Increases sound level in lower
frequencies by 18dB.
BASS BOOST CONTROL
INPUT RCAJACKS
These inputs arefor signal
cables from thesource.
Always use highquality
shielded RCAcables.
LINE OUTRCAJACKS
The LINE OUTallows you to
build multiple amplifiersystems
with out havingto use splitter
cords to distributethe signal.
Now it issimple a matterof
bringing one setof RCAs into
the first amplifier, then using
the line outRCA jacksas the
feed to thenext 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.
