Lanzar Heritage HTG158 Mono-Block Mosfet Amplifier User Guide
INTRODUCTION
LANZAR amplifiers 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 flexibility
in hosting several different speaker configurations.
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 traffic 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:
-
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. -
Should you use high or low level inputs?
Your Amplifier 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 Amplifier and the 2 front speakers. Then, use the built-in power of your radio to drive the 2 rear speakers. -
Are your components matched?
The RMS power rating of your speaker(s) must be equal or greater than the RMS power rating of your amplifier. Your speaker(s) also must be 2- 8 Ohms impedance for stable amplifier operation. Impedance information is normally printed on the speaker basket or magnet. -
Where will the amplifier 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 Amplifiers) 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.
WIRING CONNECTION
-
Ground: To Vehicle Chassis
To avoid unwanted ignition noise caused by ground loop, it is essential that the Amplifier 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). -
+12 Volt (Fused) Constant Power: To Battery (+)
Due to the power requirements of the Amplifier, 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. -
Remote Turn-On Input: To remote turn-on output of Car Stereo
This Amplifier 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
-
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. -
GAIN Control
The level control will match the amplifiers sensitivity to the source units signal voltage. The Operating range is 200mV minimum to 6V maximum.
CAUTION: Do not run the amplifier in high volume for long time, otherwise the loudspeakers will be damaged. -
SUBSONIC
The frequency can be adjusted between 0Hz and 80Hz -
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.
-
-
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. -
Bass BOOST
The boost can be selected among 0dB, 6dB and 12dB. -
REMOTE
Controls the subwoofer amplifier 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 amplifier. Even though the connectors it properly, the control knob and connector pin positions may be different and the amplifier will be damaged. -
LED
Will illuminate GREEN to indicate the amplifier is on and operating normally, and will be illuminate RED if the amplifier shuts down due to short circuit, DC off set, or overheating detected by on board protection circuitry. -
Auxiliary outputs
The Auxiliary outputs offer LANZAR amplifiers easy, unlimited system expansion.
Route RCA’s from the line out of the first amplifier to the line input of a second amplifier when using a single source output. -
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. -
Remote Turn On
This terminal turns on the amplifier when (+) 12 volt is applied to it. Connect it to the remote turn on lead of the head unit or signal source. -
(+) 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. -
FUSE
These fuses protect the amplifier against internal electrical damage and are meant to protect the amplifier only. All other power connections should be fused at the source. -
SPEAKERS
Connect subwoofers to these terminals.

Is the power
LED illuminated?| Check fuses in amplifier.
Be sure Turn-on lead is connected
AMP NOT SWITCHING ON| No power to power wire| Repair power wire or
connections
No power to remote wire with receiver on| Check connections to radio
| Fuse broken| Check fuse
| Check speaker leads| Inspect for short circuit or an open connection.

VOLUME| Check speaker load impedance| Be sure proper speakers are used
to ensure impedance recommendations are observed. (If you use an Ohmmeter to
check speaker resistance,
please remember that DC resistance and AC impedance may not be the same.)
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 amplifier 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. Conform your radio/cassette player and/or other equip
is turned off 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 different type or rating may result in damage to this system
which isn’t covered by the warranty
