X-80.4 DSP-BT

Battery disconnection:
First, disconnect the power supply of the vehicle by removing the ground cable of the battery.
Ground connection:
Connect the GND (ground) connection of the amplifier with the car chassis Keep this cable as short as possible (not longer than 50 cm) and use a suitable cross-section (AWG size 8-6). Make sure, that the connection with the vehicle chassis is free of paint, dirt, and dust.

+12V Power connection:
Connect the +12 V contact of the amplifier with the supply cable via a fuse directly to the vehicle battery. Keep in mind, that the length of the cable from the fuse holder to the vehicle battery has to be a maximum 30cm. For the amplifier to function at its best, use high qualíity fuse holder and suitable cable preferably AWG 8-6 cable. This fuse protects the amplifier and the vehicle against the possibility of a short circuit in the power cable.
Remote connection:
Connect the REM terminal of the amplifier to the remote output (automatic 12 V antenna output) of the head unit. Use a 0,5-1,5 mm power cable.

ATTENTION

Please follow the instructions during the installation of your amplifier:

Take care of a professional attachment. Pay attention, that no electrical cable, gas tank, hydraulic breaks or other components get damaged.
There has to be enough cooling and air circulation. Avoid the installation in small closed boxes or close to heating parts.
Protect the amplifier from fluids, wetness, heat and foreign material as well as from other influences.
The amplifier is only to be built into vehicles with a 12V DC power supply.
Never install the power supply cable with other original wires of the vehicle (gas cables), fan motors, brand control modules etc.
Install the signal cable (cinch cable) as well as the speaker cable far away of the power cables to avoid troubles with the music signal.
The cables of your amplifier have to be installed, so that there is no danger of binding, squeezing or breaking.

RCA CONNECTION

The X SERIES amplifier has RCA inputs, which are connected by cinch cables to the preamplifier outputs of the controller. lf this is not possible (usually with the original radio, OEM), the speaker outputs of the car radio can be connected directly to the High-Input CH 1-4 socket. It is important that the gain controls are first set to a minimum and carefully crank up during commissioning. The power amplifier is automatically switched on when a signal is present. As an accessory, the adapter cable HLAC and HLAC 10 OHM 20 W can be purchased from specialist dealers. At the RCA-DSP outputs of the output stage, it is possible to control further amplifiers with the aid of a cinch cable. With the help of the internal DSP, variable high-, band- and low- passlifters, time delay and phase shifts can be set. The DSP and Gain control settings allow you to tailor the power amp to your listening needs and speakers. About AUX-IN, other music sources to the X-80. 4 DSP-BT can be connected. The settings of the DSP are controlled by the BT-App. At the Operation Panel input, either an infrared eye DSP IR RJ for DSP RC remote control or the DSP BOX can be connected. The DSP BOX is a versatile connection tool that can be used with the DSP IR and DSP CONTROL. DSP DISPLAY and DSP RC.

The link to i0S and Android DSP software to control all settings including the manual is available at www.audio-system.de/dsp.

In this regard, AUDIO SYSTEM GERMANY recommends adjusting your amplifier through a specialized service center, dealer, or specialist.

SPEAKER CONNECTION

This power amplifier is featured with an efficient protection system to prevent any damages like overheating, overvoltage, short-circuit and DC at the loudspeaker output Occuring an error the protection-LED will light in red. In order to check the problem, first turn down all levels of the head unit, afterward turn it off.

AMPLIFIER IS NOT POWERED UP, NO LED IS LIGHTENING

ground connection professional connected?

OVERHEATING (PROTECTION LED ILLUMINATES RED WHEN AMPLIFIER IS POWERED UP)

ampilrier too hot?
short-circuit at the loudspeaker output?
short-circuit caused by loudspeaker cable with vehicle chassi (ground)?
input voltage too high (e.g.faulty generator)?

OVERHEATING (PROTECTION LED ILLUMINATES RED WHEN AMPLIFIER IS POWERED UP)

impedance alright?
loudspeaker error?
adequate airflow of the amplifier?
