parametric equalizer

These switches determine the frequencies the gain

knobs on the front panel will affect. Setting a switch

on one of the 5 bands on top of the equalizer permits

the corresponding control on the front panel to raise

or lower the gain at that frequency.

EQ Frequency Controls

Allows you to adjust the left and right channel

input sensitivity to match the output level from

your line or auxiliary source.

Input Gain Adjustments

Subwoofer Gain Control Turning this control clockwise increases the

subwoofer channel level.

Volume and Fader Control The Volume adjusts the total output level. Fader

adjusts the output balance between the front and

rear amplifiers.

Power Indicator LED This indicator lights up when the unit is properly

powered, grounded, and the remote power lead

has power to it.

Defeat Switch When the “DEF” switch is in the on position the

equalizer functions are bypassed. Depressing the

“DEF” switch again will restore the equalizer’s

operation.

Power Connections

(+12V, Remote, Ground)

1. Connect the red wire to the car battery or

other power source.

2. Connect the orange wire to the power antenna

activating wire of the car stereo.

3. Connect the black wire to the car’s chassis for

the proper ground connection.

Line and Auxiliary Inputs RCA cables are used to connect your car stereo

head unit, CD player, or other source to either

the line or aux inputs.

Subwoofer Frequency

Control

By rotating this selector you can choose any

crossover frequency from 40Hz to 400Hz. Turning

the control clockwise permits more upper bass

to travel through the sub channel.

Front, Rear &

Subwoofer Outputs

RCA cables are used to connect the front channel

outputs to the front channel amplifier inputs, the

rear channel outputs to the rear channel amplifier

inputs, and the sub outputs to the subwoofer

amplifier inputs.

Parametric EQ Controls

Turning the controls clockwise increases the level

of the sound at the frequency that you have set on

the EQ’s top panel. Counter-clockwise reduces the

level at that frequency. Choose the settings which

best match your system and your prefered audio

response.

owner’s manual wiring

Connect 12V DC from a constant battery source to a +12V slip-on spade terminal

and install a one (1) amp fuse in line.

Connect the signal processor’s GROUND to a good chassis ground, near where

the unit is mounted, or to the case of the head unit.

Connect the signal processor’s REMOTE TURN-ON lead to the remote turn-

on lead out of the head unit, and install a 1/2 amp fuse in line. (A relay

should be used if turning on more than one component, such as EQ’s,

crossovers or amplifiers.)

Connect stereo RCA cables from the head’s left and right front outputs to

the left and right inputs of the signal processor.

Connect stereo RCA cables from the left and right outputs, (and low, mid

and high outputs if applicable), of the signal processor to the left and right

inputs of your amplifier(s) or additional signal processor(s).

Turn the unit on, and adjust the input gain on the signal processor to match

the output of the head unit (1/2, or at center position, is about 1 V). Be careful

not to overdrive the input of your amplifier(s) or signal processor(s). Use

clip detectors to adjust output.

Adjust each of the crossover or equalizer controls to achieve the desired

sound characteristics.

misconnected/disconnected

• RCA cables are not faulty.

Background noise is

too high.

• Wiring is not loose or cables

misconnected/disconnected

• RCA cables are not faulty.

20

Signal Processor does not

turn on.

• Remote Turn-On wire has 12V

• 12V wire has 12V

• Ground wire is properly connected

precautions

• Never drive with the volume raised so high you cannot hear what is occuring in traffic

around you.

• Be aware that repeated exposure to excessive volume levels can permanently damage

your hearing!

• Keep all electronics away from moisture, dust, extreme heat or extreme vibrations.

• Lanzar Audio products are capable of sound pressure levels in excess of 150 dB.

Continuous exposure to sound pressure levels over 100 dB may cause permanent

loss of hearing. Use common sense and PRACTICE SAFE SOUND.

Enjoy your system, but use it wisely and safely!
