Power Connection
1. Battery disconnection: First, disconnect the power supply of the vehicle by removing the ground cable of the battery.
2. 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.
3. +12 V 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 must be maximum 30cm. For the amplifier to function at its best, use a high-quality 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.
4. 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 mm² power cable.
Attention: Further power amplifiers must be connected to the REM-Out of the X-80.4 DSP-BT to turn on.
ATTENTION! Please follow the instructions during the installation of your amplifier:
- Take care of a professional attachment. Ensure no electrical cable, gas tank, hydraulic brakes, or other components get damaged.
- There must be enough cooling and air circulation. Avoid 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 12 V 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 from the power cables to avoid interference with the music signal.
- The cables of your amplifier must 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. If this is not possible (usually with an 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 minimum and carefully cranked 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-pass filters, 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, vehicle 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, DSP CONTROL, DSP DISPLAY, and DSP RC.
The link to iOS 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 to adjust your amplifier through a specialized service center, dealer, or a specialist.
Speaker Connection
This power amplifier is featured with an efficient protection system to prevent any damages like over-heating, overvoltage, short-circuit, and DC at the loudspeaker output.
Occurring an error, the protection-LED will light in red. To check the problem, first turn down all levels of the head unit, afterwards turn it off.
Troubleshooting Guide:
- Amplifier is not powered up, no LED is lightening:
- Ground connection professional connected?
- +12V power cable professional connected?
- Remote cable professional connected?
- Fuses inserted and alright?
- Analyze voltage on the amplifier.
- Protection LED illuminates green while amplifier is soundless:
- Cinch cable alright and professional connected?
- Loudspeaker professional connected?
- Head unit alright?
- Protection LED illuminates red when amplifier is powered up:
- Amplifier too hot?
- Short-circuit at the loudspeaker output?
- Short-circuit caused by loudspeaker cable with vehicle chassis (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?
CAUTION! After cooling down, the amplifier turns on automatically.
- Error in amplifier fuse:
- Ground professional connected?
- Loudspeaker impedance alright?
CAUTION! Make sure when changing fuses to use the same value.
- Sound too low or low-distorted sound:
- Input level control “GAIN” is set to match the head unit?
- Output level control of the head unit alright?
- Loudspeaker error?
- Loudspeaker cable checked?
- Crossover frequencies has been properly set? (Check head unit, amplifier, DSP, sound processor, equalizer, frequency bandpass filter... )
- High hiss-engine noise in speakers:
- Ground connection professional connected?
- Short-circuit caused by loudspeaker cable with vehicle chassis (ground)?
- Cinch cable (RCA) and/or loudspeaker cable installed too close to the power connection cable?
- Cinch ground (RCA) of the head unit alright?
ATTENTION! Please contact your specialized dealer if the amplifier is still not working after it has been checked with the error list!
For warranty adjustment/repairs, the original invoice must be attached. Opening the power amplifier leads to a loss of warranty in either case!
