Congratulations on your purchase of a LanzarOPT! amplifier. You have purchased a quality product designed
and engineered to giveyou many years of uncompromised musical service. OPT! amplifiers are designed with
the latest technologyavailable, incorporating a DC to DC Switching PowerSupply, which provides headroom for
even
the most demanding peaks and dynamic ranges found on modern CD's and recordings.
Features
• MOSFET switches maintain rated power overa wide range of battery voltages
• PWM(Pulse-Width-Modulated) System.
• 2 Ohm Stable Stereo operation
• Stereo, BridgeMode and Tri-Mode SystemApplication 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
• Bass Boost Remote control

INSTALLATION
...... » PRE
-
1. Finda suitablelocation in thevehicle to mounttheamplifier.
2. Make surethereis sufficient air flow aroundtheintendedmountinglocation.
3. Boltthe amplifier to themountingsurface.
4. Counectthepower groundterminal to the nearestpoint on the cl1assis ofthecar. Keep
thisgroundwirelessthan one meter (39") inlength. Use 8 gauge wire.
5. Counecttheremoteterminalto theremote output of theheadunitusing 14 gaugewire.
6. Counect an emptyfuse holderwithin 300 mm (12") of thebatteryand run8 gauge or
largerhigh quality cablefrom this fuse to the amplifierlocation.
7. Make surethereis no fuse in thisfuse holder. Then maketheconnectionto the "BATf"
connectiononthe amplifier.
8.
If multiple amplifiers arebeing used, use cables (eacllwith its own fuse atthebattery)
ora #0 or #2 cable from thefuse holderatthebatteryto a distributionblockator near
theamplifier's location.
9. Connect allline inputs andoutputsusing high-quality RCA-RCA cables.
10. Iusertfuse(s) atthebatteryfuseholder(s).
11. Recheck allconnectiousbefore powering up.
12. Set alllevel controls totheirleast sensitive positions andset all crossover controls,
switcl1es, etc. to thedesiredfrequency orposition.
13. Once thesystem is powered up, setthevolume control on theheadunitto aboutthe
2 o'clockposition, andthen setalltheamplifiers'level controls for maximum output level.
14. Furtherfine tuningofthevarious controlsmay be necessarytoobtainthedesired results.
• Before you drillor cut any holes, investigate your
car's layout veIY carefully. Take care when you work
near the gas tank, fuel lines, hydraulic lines and
electrical wiring.
•Do not operate the amplifier when it is unmounted.
Attachall audio system components securelywithin
the automobile to prevent damage, especially in an
accident.
• Do not mount this amplifier so that the wire
connections are unprotected or in a pinched
condition, orlikely to be damaged by nearby objects.
Be sure to select a location inside your vehicle which
hasadequate ventilation.
• Before makingor breaking power connections in
your system, disconnect the vehicle battery. Confirm
that your head unit or otherequipment is turned
off wbile connecting the inputjacks and speaker
terminals.
• If you need to replace the power fuse, only replace
itwith a fuse identical to that supplied with the
system. Using a fuse ofa different type or rating
may resnlt in damage to your system which isn't
covered by the manufacturer's warranty.

AMPLIFIER WILL NOT POWER UP.
• Checkfor good ground connection.
• Check that remote DC terminal has at least 3v DC.
• Check that there is batterypower on the +terminal.
• Check all fuses.
• Check that ProtectionLED is not lit. If it islit, shut offamplifierbriefly and then repowerit.
HIGH HISS OR ENGINE NOISE (ALTERNATOR WHINE) IN SPEAKERS.
•Disconnect all RCA inputsto the amplifier(s) -ifhiss/noisedisappears,thenplug in the component
driving
the amplifier and unplugits inputs. Ifhiss/noise disappears, go on until the faulty/noisy
componentisfound.
• It is best to set the amplifier's input level aslowas possible. The best subjective SIN ratio
isobtainablethisway.
Try to drive ashigha signallevel from the head unit aspossible.
PROTECTION LED COMES ON WHEN THE AMPLIFIER IS POWERED UP.
• Checkfor shorts on speakerleads.
• Check that the volume control on the head unit isturneddownlow.
• Removespeakerleads, and reset the amplifier. If the Protection LED stillcomes
on,
then the amplifierisfaulty.
AMPLIFIER(S) GETS VERY HOT.
• Check that the minimum speakerimpedancefor that modelis correct.
• Checkfor speakershorts.
• Check that there is goodairflow around the amplifier. In some
applications, an external coolingfan may be required.
DISTORTED SOUND
• Check that the Level control(s)is set to match the signallevel of the
head unit.
• Check that all crossoverfrequencies have been properlyset.
• Checkfor shorts on the speakerleads.
HIGH SQUEAL NOISE FROM SPEAKERS.
• Thisis almostalways causedbya poorly-grounded RCA patch cord.
