POWER CONNECTIONS

Battery disconnection
First disconnect the power supply of the vehicle. This works out 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 6 – 10). Make sure, that the connection with the vehicle chassis is free of paint, dirt and dust.

+ 12 V / 24 V Power connection
Connect the + 12 V / +24 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 the 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 6 – 10). This fuse protects the amplifier and the vehicle against the possibility of a short circuit in the power cable.

Remote connection (optional):
You can optional connect the REM terminal of the amplifier to the remote output (automatic 12 V / 24 V antenna output) of the head unit. Therefore 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 breakes or other components get damaged.
• There has to be enough cooling and air circulation. Avoid the installation in small closed boxes or close to heatening 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 / 24 V DC power supply.
• Never install the power supply cable with other original wires of the vehicle (gas cables), fan motors, brand control moduls 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/SPEAKER CONNECTION

Der US 08 ACTIVE EVO + 24V have RCA inputs, which are connected by RCA cable with the preamp outputs of the control unit (Headunit, MP3 player, iPhone, iPad). If this is not possible (usually with an original radio, OEM), the loudspeaker outputs of the Headunit can be connected directly to the HIGH- LEVEL inputs and the switch can be set to “Auto Power”. “. The amplifier turns on automatically when a signal is present.

With the help of the INPUT GAIN controller, PHASE SHIFT, BASS BOOST and the variable frequency crossover (LOW PASS filter) you can adjust the power amplifier to the radio, to the conditions in the

With the connected RTC (cable remote control), the subwoofer can be controlled by the driver’s area.

To connect the US 08 Passive EVO to the ACTIVE, connect the 2 Asia plug connections with one another (see figure). You can also operate the US 08 Passive EVO on another power amplifier by using the SUB inputs.

ATTENTION: Plug in the white Molex connector for single operation and connect both ASIA connectors. In this regard, AUDIO SYSTEM GERMANY recommends to adjust your amplifier through a specialized service center, dealer or a specialist.
