INTRODUCTION

LANZAR ampliers provide high-performance sound reinforcement for your

mobile audio equipment. Its versatility enables compatibility with optional

Equalizers, Frequency Dividing Crossover Networks, and other audio processors

in a customized system. The Multi-Mode bridging capabilities allow exibility in

hosting several dierent speaker congurations.

To achieve optimum performance, it is highly recommended that you read this

Owners Manual before beginning installation.

WARNING

High powered audio systems in a vehicle are capable of generating "Live Concert”

high levels of sound pressure. Continued exposure to excessively high volume

sound levels may cause hearing loss or damage. Also, operation of a motor vehicle

while listening to audio equipment at high volume levels may impair your ability

to hear external sounds such as; horns,warning signals, or emergency vehicles,

thus contributing to a potential trac hazard. In the interest of safety, LANZAR

recommends listening at lower volume levels while driving.

PLANNING YOUR SYSTEM

Before beginning the installation, consider the following:

1. Do you plan to add additional mobile electronics equipment in the future?

If you plan to expand your system by adding other components sometime in

the future, ensure adequate space is left and cooling requirements are met.

2. Should you use high or low level inputs?

Your Amplier has been designed to accept Low-Level (Pre-Amp outputs from

your radio) source signal. If your radio/source is equipped with Pre-Amp outputs,

it is possible to utilize them to drive the Amplier and the 2 front speakers.

Then, use the built-in power of your radio to drive the 2 rear speakers.

3. Are your components matched?

The RMS power rating of your speaker(s) must be equal or greater than the

RMS power rating of your amplier. Your speaker(s) also must be 2- 8 Ohms

impedance for stable amplier operation. Impedance information is normally

printed on the speaker basket or magnet.

4. Where will the amplier be installed?

Consider both the length of your leads, and routing when determining the

mounting location. It is best to run power and RCA wiring on opposite sides of

the vehicle to prevent induced noise. Pre-amp input jacks require a length of

high quality shielded male to male RCA patch cord.

CONNECTINGTHE POWER

CAUTION

AS A PRECAUTION, DISCONNECTTHE POWER WIRE FROM THE BATTERY WHILE

MAKING THE POWER AND GROUND CONNECTIONS TO THE AMPLIFIER.

4/8 GAUGE (Thicker if planning for additional Ampliers) wire is recommended

for both the power and ground wires 12 Gauge, for the remote turn-on wire 16

Gauge. Both types are available at most Mobile Audio Dealers or Installation

Shop.

www.Lanzar.com

WIRING CONNECTION

1. Ground: To Vehicle Chassis

To avoid unwanted ignition noise caused by ground loop, it is essential that the

Amplier be grounded to a clean, bare, metal surface of the vehicle's Chassis

NOTE:

GROUND WIRE SHOULD NOT BE EXTENDED MORE THAN 3 FT. (1 METER).

2. +12 Volt (Fused) Constant Power: To Battery (+)

Due to the power requirements of the Amplier, this connection should be

made directly to the positive (+) terminal of battery. For safety measures,

install an in-line Fuse Holder (not included) as close to the battery positive (+)

terminal as possible with an ampere rating; not to exceed total value of fuses

in Amp.

3. Remote Turn-On Input: To remote turn-on output of Car Stereo

This Amplier is turned "ON" remotely when the vehicle's stereo is turned "ON".

NOTE:

IF YOUR RADIO DOES NOT HAVEA +12 VOLT OUTPUT LEAD WHEN THE RADIO IS

TURNED ON，THE "REMOTE" TERMINAL ON THE AMPLIFIER CAN BE CONNECTED

TO VEHICLE'S ACCESSORY CIRCUIT THAT IS LIVE WHEN THE KEY lS "ON".

CONTROL FUNCTIONS

1. RCA input jacks

These RCA input jacks are for use with source units that have RCA or Line level

outputs. A source unit with a minimum level of 200mV is required for proper

operation. The use of high quality twisted pair cables is recommended to

decrease the possibility of radiated noise entering the system.

2. GAIN Control

The level control will match the ampliers sensitivity to the source units signal

voltage. The Operating range is 200mV minimum to 6V maximum.

CAUTION: Do not run the amplier in high volume for long time, otherwise

the loudspeakers will be damaged.

3. SUBSONIC

The frequency can be adjusted between 0Hz and 80Hz.

www.Lanzar.com

4. X-OVER

• Full pass x-over switch

When the switch is in the "Full" position, the full range is bypassed.

• Low pass x-over switch

When the switch is in the "LPF" position, frequencies lower than the low pass

frequency setting are passed. The frequency can be adjusted between 50Hz

and 250Hz.

• High pass x-over switch

When the switch is in the "HPF" position, frequencies higher than the high

pass frequency setting are passed.

5. Low pass x-over frequency control

This control is used to select the desired low pass x-over frequency.

The frequency can be adjusted between 50Hz and 250Hz.

6. Bass BOOST

The boost can be selected among 0dB, 6dB and 12dB.

7. REMOTE

Controls the subwoofer amplier gain, from a remote location for ease of

adjustment during listening.

Warning:

Do not connect a level control knob from other manufacturers to the Remote

Sub Level Control of any amplier. Even though the connectors t properly, the

control knob and connector pin positions may be dierent and the amplier

will be damaged.

8. LED

Will illuminate GREEN to indicate the amplier is on and operating normally,

and will be illuminate RED if the amplier shuts down due to short circuit, DC

oset, or overheating detected by on board protection circuitry.

9. Auxiliary outputs

The Auxiliary outputs oer LANZAR ampliers easy, unlimited system expansion.

Route RCA's from the line out of the rst amplier to the line input of a second

amplier when using a single source output.

www.Lanzar.com

10. GND

Connect this terminal directly to the sheet metal chassis of the vehicle, using

the shortest wire necessary to make this connection. Always use wire of the

same gauge or larger than the (+)12 volt power wire. The chassis connection

point should be scraped free of paint and dirt. Use only quality crimped and/

or soldered connectors at both ends of this wire.

Warning:

Do not connect this terminal directly to the vehicle battery ground terminal

or any other factory ground points.

11. Remote Turn On

This terminal turns on the amplier when (+) 12 volt is applied to it.

Connect it to the remote turn on lead of the head unit or signal source.

12. (+) 12 Volt Power

Connect this terminal through a FUSE or CIRCUIT BREAKER to the positive

terminal of the vehicle battery or the positive terminal of an isolated audio

system battery.

Warning:

Always protect this power wire by installing a fuse or circuit breaker of the

appropriate size within 12 inches of the battery terminal connection.

13. FUSE

These fuses protect the amplier against internal electrical damage and are

meant to protect the amplier only. All other power connections should be

fused at the source.

14. SPEAKERS

Connect subwoofers to these terminals.

TROUBLESHOOTING GUIDE

WARNINGS

Investigate the layout of your automobile thoroughly before drilling or cutting any

holes. Take care when to work near the gas tanks, lines, or hydraulic lines, and

electrical wiring. Don't use power amplier unmounted. Attach this system securely

to the auto-mobile to prevent damage, particularly in the event of an accident.

Don't mount this system so that the wire connections are unprotected or are

subject to pinching or damage from nearby objects. The +12V DC power wire must

be fused at the battery positive terminal connection. Before making or breaking

power connections at this system power terminals, disconnect the +12V wire at

the battery end. Conrm your radio/cassette player and/or other equip is turned

o while connecting the input jacks and speaker terminals. If you need to replace

the power fuse, replace it only with a fuse identical to that supplied with the system.

Using a fuse of dierent type or rating may result in damage to this system which

isn't covered by the warranty.
