Please note

•As a precaution it is advisable to disconnect the vehicle’s battery before making connection to the +12 Volts supply wiring

(see owner’s manual of your car for further information).

•Please use great caution drilling your trunk. Your gas tank and brake lines can be damaged by puncturing with your drill bit –

this could cause damage or failure of your cars operating systems.

•Never pass wires over sharp angles. It is recommended to buffer the power supply of the amplifier with an additional

capacitor (power cap) min. 1 F to guarantee a stable operation voltage.

WARNING !

High powered audio systems in a vehicle are capable of generating "Live Concert" 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 constituting to a potential traffic hazard. In the interest of safety, Consumer Electronics recommends listening at lower volume levels

while driving.

Planning your system

Before beginning the installation, consider the following:

a) 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.

b) If your radio is equipped with preamplifier outputs (RCA), it is advisable to use them.

Mounting your amplifier

a) Select a suitable location that is convenient for mounting, is accessible for wiring and has ample room for air circulation and

cooling.

b) Use the amplifier as a template to mark the mounting holes, remove the amplifier and drill 4 holes. Then mount the amplifier

with the mounting screws.

Warning

Chose a mounting position where all electric wires are protected from being damaged by sharp edges, heat or other conditions. +12Volt

DC electrical connections must be fused on the battery side. Make sure your radio and all other devices will be turned off while connection

your system.

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.

Controls and functions

Speaker terminals

For connection of the subwoofer

Power terminals

GND -> Ground connection

REM -> Remote antenna terminal

BATT -> +12 Volt

Satus indication

GREEN – OK

RED – Error

Cinch inputs

Terminal for connection of the RCA wires.

To avoid failure, please use high quality RCA wires.

Input level controller

With this controller you can adjust the input sensitivity.

Bass boost controller

For adjusting of the bass boost level in the range from 0 to +12 dB.

Low pass controller

Adjust the variable lowpass frequency to the desired frequency between 30

and 250 Hz using the controller.

Master / Slave Switch

For choosing the operation mode of each amplifier in link mode.

Cinch Outputs

For connection of additional amplifiers in fullrange operation.

Remote control input

For connection of the bass remote control.

Phase shift controller

This controller allows you to fit the subwoofer channel in-phase to the front

system.

Subsonic controller

This controller allows you to filter low frequencies in a range between 10

and 50 Hz. This function reduces the mechanical Xmax and raises the

capacity of the connected subwoofer.

Master/Slave

Cinch-In-/Output

Cinch In- / Output for operation of two same amplifiers (2x GZTA

1.800DX or 2x GZTA 1.1200DX) in linkmode.

Turning on the amplifier

The amplifier automatically turns on a few seconds after you turn on your radio.

Note: Your amplifier temporarily shuts down if it gets too hot, then restarts automatically once it cools

(At about 80° / 176° F).

Adjusting the audio level

1. LEVEL (Min/Max): Turn fully counter- clockwise to MIN position

2. Turn the auto sound system's volume control to about two-third of its full range.

3. Adjust LEVEL to a comfortable listening level.
