User manual BOSS DIABLO D400.2

[. . . ] The current draw will also increase by about the same amount, so be sure you have enough current to run the amplifiers into a 2 Ohm load. If you lack adequate current, your music reproduction will be distorted. OUTLAW MOSFET Amplifier User's Manual - page 3 General precautions Before installing and using your new amplifier, please become familiar with all the information contained in this manual. Please keep this manual in a safe place for future reference. · Do not open or attempt to repair this unit yourself. [. . . ] Make sure there is sufficient air circulation around the intended mounting location. Mark the location for the mounting hole screws by positioning the amplifier where you wish to install it. Use a scribe or mounting screw, inserted through each of the amp's mounting holes, to mark the mounting surface. If the mounting surface is carpeted, measure the hole centers and mark with a felt tip pen. Drill pilot holes in the mounting surface for the mounting screws. Place the amplifier in position, and attach the amplifier to the mounting surface securely using screws. Installation precautions Before you drill or cut any holes, investigate your car's layout very carefully. Take special care when you work near the gas tank, fuel lines, hydraulic lines and electrical wiring. Never operate the amplifier when it is unmounted. Attach all audio system components securely to prevent damage, especially in an accident. SHOCK HAZARD!There are dangerous voltages present within the unit. There are no user-serviceable parts within the unit. OUTLAW MOSFET Amplifier User's Manual - page 4 Connecting the amplifier Before doing any wiring, look through this manual and identify the diagrams to follow for power, input and speaker connections for your particular installation. It can also cause the protection circuit to engage. OUTLAW MOSFET Amplifier User's Manual - page 5 Low Level Input Wiring Low-level (RCA) input wiring is preferred for best audio performance. Always use a high-quality RCA cable for best audio performance. NOTE: Do not connect BOTH the high level and low level inputs from your receiver to your amplifier at the same time! 4-Channel Amplifiers OL1800 and OL2400 Remote Subwoofer Level Control CH1/2 BASS BOOST INPUT LEVEL + CH1 CH2 LOW LEVEL INPUTS CH3 CH1 CH1/2 CROSSOVER FREQ 40Hz LOW PASS 150Hz FULL RANGE FULL RANGE HIGH PASS MODE HIGH PASS + HIGH INPUTS BASS BOOST INPUT LEVEL REMOTE SUBWOOFER LEVEL CONTROL + CH 3/4 CH4 CH3 + CH 3/4 CROSSOVER CH4 CH2 40Hz LOW 150Hz PASS HIGH INPUTS FREQ MODE To REAR Audio Outputs of head unit or signal processor To FRONT Audio Outputs of head unit or signal processor OUTLAW MOSFET Amplifier User's Manual - page 6 High Level Input Wiring The high level input(s) should only be used when your head unit lacks RCA outputs. If the RCA outputs are not present, connect the speaker outputs from the receiver to the high level input connector of the amplifier. Be sure to observe polarity to avoid audio phase problems. NOTE: Do not connect BOTH the high level and low level inputs from your receiver to your amplifier at the same time!

The main speakers will operate in STEREO while the subwoofer simultaneously operates in MONO. To set up the amplifier to run in this mode, put the crossover switches in the FULL position. Insert high pass filter capacitors and a low pass filter inductor into the wiring as shown below. Be sure to check the table at the bottom of this page to determine the correct capacitor and inductor values for the crossover frequency you wish to achieve.

[. . . ] Remove speaker leads, and reset the amplifier. If the Protection LED still comes on, then the amplifier is faulty and needs servicing. Check that amplifier is properly grounded. Check that the Remote Input (Turn-On) has at least 3VDC. [. . . ]
