FEATURES
Congratulation on your purchase of your new CARBON-SERIES amplifier.
IMPORTANT: Before installation your power amplifier, we recommend to read
the owner´s manual carefully and to follow the instructions regarding
connection and fitting exactly.
ATTENTION: Pay attention to advices and instructions of the car
manufacturer.
IMPORTANT: Your proof of purchase is evidence of warranty claim for
repair or replacement. Keep your proof of purchase, manual and original
packaging.
ATTENTION: Use of sound components can impair your ability to hear
necessary traffic sounds and may constitute a hazard while driving your
automobile.
AUDIO SYSTEM GERMANY accepts no liability for hearing loss, bodily injury
or property damage as a result of use or misuse of our products. We recommend
installing the equipment by an authorized service center or dealer. A
professional fitting and connection is the requirement for further warranty
and perfect sound.

POWER CONNECTION
CARBON-500.1D / CARBON-250.4
-
Battery disconnection
First disconnect the power supply of the vehicle. This works out the best 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 sice 8 – 6). Make sure, that the connection with the vehicle chassis is free of paint, dirt and dust. -
+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 fuse holder to vehicle battery has to be a maximum of 30 cm. Requirement for a perfect function of the amplifier is a qualitative high end fuse holder as well as a suitable cable cross section (AWG sice 8 – 6). 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.
Therefore use a 0,5 – 1,5 mm² power cable.
ATTENTION
Please follow the instructions during the installation of your amplifier:
a) Take care of a professional attachment. Pay attention, that no electrical
cable, gas tank, hydraulic breaks or other components get damaged.
b) There has to be enough cooling and air circulation. Avoid the installation
in small closed boxes or close to heartening parts.
c) Protect the amplifier from fluids, wetness, heat and foreign material as
well as from other influences.
d) The amplifier is only to be built into vehicles with a 12 V DC power
supply.
e) Never install the power supply cable with other original wires of the
vehicle (gas cables), fan motors, brand control modules etc.
f) Install the signal cable (cinch cable) as well as the speaker cable far
away from the power cables to avoid troubles with the music signal.
g) The cables of your amplifier have to be installed, so that there is no
danger of binding, squeezing or breaking.
RCA CONNECTION
CARBON-500.1D
CARBON-250.4
The CARBON -SERIES amplifier offers RCA-Inputs, which are connected
through cinch cables with the preamplifier-outputs of the head unit. If the
head unit (OEM-RADIO) has no RCA-Output, then it is possible to connect the
speaker output direct to High-Input of the amplifier.
Important: the Gain-Controller has to be adjusted to minimum, then
carefully turn up the volume. If signal is presented, the amplifier
automatically turns on.
With the aid of the variable high- and lowpass filter, phase shift-controller,
the gain-controller and subsonic filter you are able to adjust the amplifier
on to your preferred taste of hearing, the circumstances of the vehicle and to
the speakers.
The wired remote controller RTC can be installed to adjust the output level.
With CARBON-250.4 the RTC adjusts the level of channel 3 and 4 only when
lowpass filter is selected.
In this regard, AUDIO SYSTEM GERMANY recommends to adjust your amplifier
through a specialized service center, dealer or a specialist.
SPEAKER CONNECTION
CARBON-500.1d
Mono Betrieb
Speaker
impedance 2 ~ 8 Ohm
Dual Mono Betrieb
Speaker
impedance 4 ~ 8 Ohm
Please take care the CARBON-500.1 d is a pure 1 channel amplifier. If using 2 subwoofers or a double voice coil subwoofer in parallel configuration take care each subwoofer/voice coil resistance must not be below 4 Ohm so the resulting total resistance is not below 2 Ohm.
CARBON-250.4
2-Channel Mono
Speaker impedance 4 ~ 8 Ohm
4-Channel Stereo
Speaker impedance 2 ~ 8 Ohm
3-Channel Stereo + Mono
Speaker impedance 4 ~ 8 Ohm
TROUBLE SHOOTING
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. In order to check the problem, first turn down all levels of the head unit, afterwards turn it off.

professional connected?
– +12V power cable professional connected?
– remote cable professional connected?
– fuses inserted and alright?
– analyze voltage on the amplifier.

– 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, soundprozessor, equalizer, frequency
bandpass filter…)
HIGH HISS-ENGINE NOISE IN SPEAKERS| – ground connection professional
connected?
– short-circuit caused by loudspeaker cable with vehicle chassis (ground)?
– cinchable (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 has to be attached!
Opening the power amplifier is leading to a lost of warranty in either case!
