USER MANUAL Zeus ZRX220A Hifonics

Please read the user‘s manual carefully before the installation and the rst operation of the amplier. All Specications are subject to change

IMPORTANT NOTES PRIOR TO INSTALLATION

• This device is only suited for a 12 volt system with negative ground.
• Ensure that the input and output cables are sufciently separated from the power supply cables. Otherwise interferences may occur.• Ensure the accessibility of the fuse and the operating elements after installation.
• The reliability and performance of the amplier depends on the quality of installation. Preferably consult an expert to install the system.
• Avoid any damage or removing of the components of the vehicle like wires, cables, board computer, seat belts, gas tank or the like.

POWER SUPPLY AND TURN-ON-CONNECTION

ATTENTION: Before you start with the installation, disconnect the ground connection from the ve- hicle’s battery in order to prevent short circuits.The power wiring which is usually installed in on-board car networks is not sufcient for a power amplier‘s demands. Make sure that the power wires to GND and to the +12 V terminal has been sufciently specied. First connect the GND terminal [ 6 ] of the amplier to an appropriate ground connection at the chassis. To ensure a good connection, residue dirt and dust from the connection point. A loose connection may cause malfunctions or interferences noise and distortion. Then connect the +12 V terminal [ 4 ] of the amplier with the battery by using an appropriate cable including an in-line fuse. This fuse [ 2 ] should be located very close to the battery [ 1 ]; for safety reasons not more than 30 cm away. Only insert the fuse when the installation, including the connection of the loudspeakers, has been accomplished. Then connect the remote turn-on-wire [ 3 ] from the head unit with the amplier‘s REM terminal [ 5 ]. A cable with a cross-section of 0.5 mm is adequate.

When installing the audio cables between the RCA outputs of the head unit and the RCA inputs of the amplier [ 7 ], the audio and power supply cables should, if possible, not be routed along the same side of the vehicle. We recommend a separated installation, e.g. routing the power cable through the cable channel on the left side and the audio cables through the cable channel of the vehicle on the right side or vice versa. This prevents interferences due to crosstalk into the audio signal.

Push the AUTO TURN ON switch [ 9 ] to ON position. The amplier detects now a voltage rise (6 Volts) over the connected input signal on the HI LEVEL INPUT [ 8 ] when the head unit will be switched on. Hence, the amplier will also be turned on. As soon as the head unit will be turned off, the amplier turns also automatically off. In this case the turn-on connection [ 3 ] is not needed. NOTE: The AUTO TURN ON function usually works with 90% of all head units, because they are equipped with ”High Power”-outputs. Only with a few older and still existing head units the Auto Turn On function is not working.

HIGH LEVEL INPUTS & AUTO TURN ON

The high level inputs under HI LEVEL INPUT [ 8 ] is suitable to connect the device input with speaker wires, if your head unit is not equipped with pre-amplier RCA outputs. Extend therefor every regarding speaker cable from your head unit with appropriate speaker cables from your car audio retailer to the mounting location of the amplier. Then connect the each matching loudspeaker cable with the cables of the included High Level Input jack. CAUTION: Never use the high level inputs and the RCA inputs at the same time. This may damage the device seriously. INPUT SENSITIVITY Turn the LEVEL [ 10 ] controller of the amplier to the MIN position. Then turn the volume controller of the head unit to 80 - 90% of its full setting. Now turn LEVEL [ 10 ] clockwise until you hear some distortion. Then turn back LEVEL [ 10 ] slightly until you hear a cleaner sound.

PROTECTION CIRCUIT The PROTECT LED [ 16 ] lights up red, when the amplier is overheated, or a short circuit occurs respective a too low impedance load is connected to the speaker outputs. If this events, the internal built-in protection circuit shuts down the amplier automatically. The amplier should work again properly after you have solved the problems.The POWER LED [ 17 ] lights up green, if the amplier is in operation.

By using the BOOST controller [ 11 ] you are able to increase the bass enhancement from 0 to 12 dB. ATTEN- TION: Use the BASS BOOST wisely!

Set the desired crossover frequency by using the controller LPF [ 13 ]. Thus to that only the frequencies below the chosen crossover frequency will be amplied and the subwoofer plays more precisely and efcient.

The PHASE SHIFT switch [ 12 ] allows to switch the phase from 0° to 180° to match the output signal with the vehicle’s interior acoustic.

BASS LEVEL REMOTE CONTROLLER

With the included bass level cable remote controller [ 15 ] allows to adjust the bass level e.g. out of the driver’s seat. Connect the remote controller and the BASS LEVEL CONTROLLER terminal [ 14 ] with the enclosed cable.
