Thank you for purchasing this AVATAR product! AVATAR is committed to the creation of extremely high-profile systems with

no loss of quality.

To ensure proper use, please read through this manual before using this product. It is especially important that you read and

observe CAUTION’s in this manual. Please keep the manual in a safe and accessible place for future reference.

1. INTRODUCTION EN

1. This unit is for vehicles with a 12V battery and negative grounding. Before installing in recreational vehicles, trucks or buses,

check the battery voltage.

2. Check the state of on-board power supply of your vehicle, the battery and the generator. When the motor is running,

depending on the ambient temperature, the voltage to be outputted by the generator is within the range of 14 to 14.7 V. Open

circuit voltage (OCV) of the battery must be within the range of 12.5 to 13 V. Make sure that the rated current of the generator and

the battery capacity is enough to provide increased consumption.

For example, for the power of the amplifier 1000 W, the rated current of the generator is required at the rate of 1000 W / 13 V

= 77 amperes. A more powerful amplifier requires a more powerful generator as well as an additional battery.

3. Do not place the amplifier in either the engine compartment or the places exposed to water, moisture, dust or dirt.

4. Never stretch the cables outside the car and near the moving parts of the car. This can lead to destruction of the insulating

layer, short circuit and fire.

5. The amplifier should be installed in areas of the car where the temperature is from 0 °C (32 °F) to 55 °C (131 °F). The amplifier

should be in a place with a good air circulation. The horizontal position of the amplifier is the best way to install.

6. During the operation the amplifier may be heated up to 80 °C (176 °F). Before you touch it, make sure it is not overheated

that may be dangerous.

7. To improve the cooling of the amplifier, it is recommended to clean periodically the heatsink from dust. When cleaning the

heatsink strong solvents should not be used as they may damage the amplifier. Do not use compressed air, because solids can

penetrate inside the amplifier. Cleanings best done with wet towels or cloth.

8. Make sure that the location of the amplifier does not violate the proper operation of mechanical and electrical devices of

the vehicle.

9. Make sure that during the installation and connection of the battery, the power cables are not shorted.

10. When performing plumbing, drilling or cutting works with the car, make sure that there is no wiring, brake lines, fuel pipe

or other structural elements under the place of work. Follow the safety rules! Use protective glasses and gloves.

11. To protect the wires use rubber gaskets if the wire passes through a hole in the plate, or other similar materials if it lies

close to the parts exposed to heat.

12. Make sure that all the cables are fixed over the entire length. Also make sure that their outer protective shell is non-

combustible. Use a clamping screw to secure the positive and negative cables next to the appropriate terminals of the amplifier.

13. Select a diameter of the power cable in accordance with the power of the amplifier and the recommendations provided

here. Power cables are extremely important since they directly affect the system damping factor and sound quality. The cables to

the battery must be in the copper crimp terminals with the help of a hydraulic press, and is well secured to the battery terminals.

14. To avoid accidental damage, keep the amplifier in its original packaging prior to installation.

15. Use high-quality copper speaker cables.

CAUTION!!! High sound pressure can damage your health! Please use the common sense when controlling volume!

2. SAFETY INSTRUCTIONS

3. TYPICAL INSTALLATION SEQUENCE

1. Before installing the ampliﬁer disconnect the battery from the electrical system.

2. To connect the ampliﬁer it is necessary to stretch the power cable from the location of the battery to the place of installation

of the ampliﬁer. Select the power cable with the appropriate regulations in AWG (see Table: Power cable)

3. Connect the power supply with the correct polarity. Connect all (+) terminals of the ampliﬁer to the cable from the positive

terminal of the battery and the (-) terminals of the ampliﬁer – to the cables running from the negative terminal of the battery.

4. Place the fuse holder for each positive cable within 40 cm from the positive terminal of the battery and connect one end of

the power cable to the holder after connecting the other end to the ampliﬁer. Do not install the fuse.

5. Route all signal cables next to each other and separately from the power cables.

6. Connect the wires of RCA input. The input signal must be between 0.3 VRMS and 5 VRMS.

7. To connect the power wire supply is necessary to use special cables.

8. Fasten the ampliﬁer properly when installing it in the vehicle. If the component is disconnected during driving, it may cause

serious damage to the passengers of the car or another vehicle.

9. After installation is complete, check the wiring of the system and make sure that all connections have been made correctly.

Before installing the fuses, disconnect the positive lead from the battery and then install the fuse in the fuse holder. Using the light

bulb 12 V 21 W, connect the positive lead to one contact of the bulb and the other contact of the bulb to the positive terminal of

the battery.

When properly connected, the bulb must brieﬂy light up and go out. Now you may connect the positive lead to the (+)

battery. If the light does not go out, then something is wrong. This will prevent damage to the ampliﬁer in case of reverse polarity

and unwanted sparks when connecting. Install the rest of the fuses.

10. To activate the ampliﬁer, it is necessary to apply the positive potential of 12 volts to the control input of the ampliﬁer

(REMOTE IN) through a switch or a corresponding control output (REMOTE OUT) with the head unit (HU).

11. LED indicator on the front panel lights up in green, indicating that the device is turned on. LED indicator lights up in red

when the outputs are overloaded, if the temperature protection is activated, if there is a short circuit in the system cables to the

heatsink and if the ampliﬁer is faulty.

12. The sound level is calibrated by adjusting the volume of the source up to 3/4 of its maximum level. Then, adjust the level of

the ampliﬁer up until you hear distortion.

Avatar ampliﬁers are high-quality and technically perfect products. The problems often arise due to improper

operation, faulty connection of components or lack of power supply of the on-board network.

1) The ampliﬁer does not turn on.

Problem solution: Check all the contacts and the presence of the ampliﬁer 12 V at the terminals. Check whether the

control input of the ampliﬁer "Remote in" receives the positive potential of 12 V.

2) Power turns on, but goes into protection (security indicator lights up)

Problem solution: Check if there is a short circuit (fault) on the ampliﬁer output which is connected to the speakers or

subwoofers. Make sure that commutation of the coils of the subwoofer is correct. The rated resistance of the coils should

not be lower than the permissible rated load impedance of the ampliﬁer. Check the supply voltage of the ampliﬁer. It

must be within the range of 12-15 V for 12 V versions.

3) The ampliﬁer turns on but at a high volume it goes to protection. Problem solution: The ampliﬁer may lack power.

Make sure that the rated current of the generator and the battery capacity is enough to provide the ampliﬁer with the

increased consumption.

Check the ampliﬁer for overheating. Check the load resistance.

4) The ampliﬁer is turned on, but there is no sound from the speakers or subwoofer.

Problem solution: Check the connection of the ampliﬁer, the integrity of the interconnecting cable, HU, the speaker or

the subwoofer.

СОДЕРЖАНИЕ RU

1. ВВЕДЕНИЕ RU

1. Убедитесь, что ваш автомобиль имеет электросистему напряжением 12 VDC с заземлением отрицательного

полюса.

2. Проверьте состояние бортовой сети Вашего автомобиля, состояние аккумуляторной батареи (АКБ) и генератора.

При заведенном двигателе, в зависимости от температуры окружающей среды, напряжение выдаваемое генератором

должно быть в пределах от 14 до 14,7 Вольт. Напряжение разомкнутой цепи (НРЦ) батареи должно быть в пределах от

12,5 до 13 Вольт. Убедитесь в том, что номинального тока генератора и емкости АКБ хватит для обеспечения

повышенного потребления.

К примеру, для питания усилителя мощностью 1000 Вт, необходим номинальный ток генератора из расчета 1000 Вт/13

Вольт=77 Ампер. Для более мощного усилителя (-ей) необходимы более мощный генератор, а так же дополнительный

АКБ.

3. Не устанавливайте усилитель в подкапотном пространстве, а также в местах, подверженных воздействию воды,

повышенной влажности, пыли или грязи.

4. Никогда не протягивайте провода снаружи автомобиля, и возле двигающихся частей автомобиля. Это может

привести к разрушению изоляционного слоя и короткому замыканию.

5. Установку усилителя необходимо производить в тех местах автомобиля, где температура составляет от 0°C (32°F) до

55°C (131°F). Усилитель должен находиться в таком месте, где обеспечивается хорошая циркуляция воздуха.

Горизонтальное положение усилителя является наилучшим способом установки.

6. В процессе эксплуатации усилитель может нагреваться до 80°C (176°F). Перед тем, как трогать его, убедитесь в том,

что он не перегрет, что может быть опасным.

7. Для улучшения охлаждения усилителя, рекомендуется периодически очищать корпус (радиатор) от пыли. При

очистке корпуса не рекомендуется использовать сильнодействующие растворители, так как они могут привести к

повреждению усилителя. Не используйте сжатый воздух, поскольку внутрь усилителя могут проникнуть твердые

частицы. Очистку лучше всего производить влажными салфетками или тканью.

8. Убедитесь в том, что выбранное Вами место расположения усилителя, не нарушает правильную работу

механических и электрических устройств автомобиля.

9. Убедитесь в том, что во время установки и подключения аккумулятора, силовой кабель не замкнут накоротко.

10. При проведение слесарных работ, сверлении или резки металла автомобиля, убедитесь что под местом работ нет

электропроводки, трубопроводов тормозной системы , бензопровода либо других элементов конструкции. Соблюдайте

технику безопасности! Используйте защитные очки и перчатки.

11. Для защиты проводов используйте резиновые прокладки (если провод идет через отверстие в пластине) или

другие подобные материалы, если он пролегает рядом с частями, подверженными нагреву.

12. Убедитесь, что все кабели зафиксированы по всей длине. Также убедитесь, что их внешняя защитная оболочка

является негорючей. С помощью винтового зажима закрепите положительный и отрицательный кабели рядом с

соответствующими клеммами усилителя.

13. Выбирать сечение силового кабеля необходимо в соответствии с мощностью усилителя и данными здесь

рекомендациями. Кабели электропитания чрезвычайно важны, так как они напрямую влияют на коэффициент

демпфирования системы и качества звука. Кабели, идущие к АКБ необходимо обжимать в медные наконечники при

помощи гидравлического пресса, и хорошо закреплять к клеммам АКБ.

14. Во избежание случайных повреждений, храните усилитель в исходной упаковке до начала установки.

15. Используйте качественные медные акустические провода.

Помните! Высокое звуковое давление может навредить вашему здоровью, поэтому

руководствуйтесь здравым смыслом и практикуйте безопасный звук.
