Frequently Asked Questions - Black Core Two LTD MAGNAT

What is the maximum output power of the amplifier?

In stereo, the maximum power is 2 x 300 W at 4 Ω and 2 x 400 W at 2 Ω. In bridged mode, it reaches 1 x 800 W at 4 Ω.

What is the minimum impedance I can use?

In stereo operation, the minimum impedance is 2 Ω per channel. In bridged mode, it is 4 Ω.

How do I wire the amplifier in bridged mode?

For bridged mode, connect the speaker positive terminal to the CH1+ terminal and the negative terminal to the CH2- terminal. Ensure the total impedance does not drop below 4 Ω.

What type of power cable should I use?

Use a cable with a cross-section of at least 10 mm² for the +12 V and GND connections. The fuse should be placed within 60 cm of the battery.

How do I adjust the input level?

Set the car radio volume to about 75%, then adjust the Level potentiometer on the amplifier until you get a clean sound without distortion.

What filters are available and how to use them?

The amplifier has a low-pass filter (LPF) and a high-pass filter (HPF), both adjustable from 40 to 300 Hz. Use LPF for a subwoofer and HPF for satellite speakers.

How do I use the Bass Boost function?

The Bass Boost increases low frequencies by 0 to 12 dB at 45 Hz. Adjust it to your preference, but avoid excessive boost to prevent speaker damage.

Can I connect multiple amplifiers?

Yes, the amplifier has LINE OUT (RCA) outputs that pass the input signal to another amplifier without loss of quality.

How to safely install the amplifier?

Place the amplifier in a well-ventilated area, away from dust and moisture. Ensure the cooling fins are not obstructed. Disconnect the battery before any work.

What to do if the protection LEDs light up?

The red LED indicates overload or short circuit. Check speaker connections and impedance. The green LED indicates normal operation. If the red stays on, reduce volume or check installation.

3. IMPORTANT INSTALLATION INFORMATION

• This appliance may only be connected to a 12 volt system with negative ground.
• The heat radiated when the amplifier is used means that sufficient air circulation is required at the installation. It is very important that the cooler's cooler ribs do not contact any metal plating or a which could impair air circulation. The amplifier may not be installed in small confined spaces or without air circulation (e.g. spare wheel recess or under the vehicle carpeting). Installation in the I recommended.
  · Install the amplifier in such a way that it is protected as far as possible against vibrations and du
• Make sure that the input/output cables are sufficiently distant from the power supply cables as other interference may occur.
• Make sure that the fuse and operating elements are accessible after installation.
  The appliance's reliability and performance depend on the quality of installation. Preferably get an ex install the system, particularly if you want to install several loudspeakers or a complex multi-way s

4. CONNECTIONS

4.1 POWER SUPPLY AND AUTOMATIC SWITCHING ON

Important notice: Before commencing the installation, disconnect the plus terminals from the car battery in order to prevent short circuits.

The power cabling usually installed in on-board car networks is not sufficient for a power amplifier's (Make sure that the power lines to GND and to the +12 V terminal have been sufficiently specified. section of at least 10 mm^2 must be used to connect the battery to the amplifier's terminals.

First connect the amplifier's GND terminal to the battery's minus pole. It is very important that the cold good. Dirt residues must be carefully removed from the battery's connection point. A loose connection with malfunctions or interference noise or distortion.

The +12 V amplifier connection must then be connected with a power cable possessing an integrated the battery's plus pole. The fuse must be located close to the battery, the length of cable from the pole to the fuse must be less than 60 centimetres for safety reasons. Only insert the fuse when all work, including the connection of the loudspeakers, has been completed.

Now connect the car hi-fi receiver's remote control connection to the amplifier's REM control jack. A cross-section of 0.75mm^2 is sufficient for connecting the amplifier's REMOTE connection and the device.

4.2 AUDIO CABLES

When installing the audio cable between the cinch output of your car receiver and the cinch input of inside your car, the audio and power supply cables should, wherever possible, not be routed along the side of the vehicle. We recommend an isolated installation, e.g. routing the power cable through the on the left-hand side and the audio cable through the cable duct on the right-hand side or vice versa, interference due to crosstalk into the audio cables.

4.3 LOUDSPEAKER CONNECTIONS

In normal operating mode (i.e. one loudspeaker on each individual amplifier channel), the lowest to resistance is 2 ohm per channel.
- In bridging mode (two amplifier outputs combined) the lowest terminal resistance doubles to 4 ohm.
· The impedance in tri-mode may not fall below 2 ohm per channel.
- Never connect the loudspeakers' minus terminals to the vehicle chassis.
- Never connect the +12 V supply voltage to a loudspeaker output as this would destroy the amplifier stage.
If the amplifier is operated with lower terminal resistances or incorrectly used as described above, amplifier and the loudspeakers may be damaged. The warranty becomes void in such cases.

5. OPERATING ELEMENTS AND IN/OUTPUTS

5.1 SETTING THE INPUT SENSITIVITY

The input sensitivity may be adapted to any car radio or tape deck. Turn the volume control of you central position and then adjust the input-level control (3) to produce an average medium volume. This usually provides sufficient power reserves at optimum weighted noise voltage.

ATTENTION: only reproduce loud test noises briefly to prevent damaging the loudspeakers.

5.2 LOW-PASS FILTER WITH ADJUSTABLE CROSS-OVER FREQUENCY

If the amplifier is used as a subwoofer amplifier, set the switch (7) to "LPF". Set the desired cross-with the control (6). This makes the filter adaptable to the installed woofer's sound requirements.

The filter's high edge steepness is responsible for the precision reduction of medium and high frequer

5.3 HIGH-PASS FILTER WITH ADJUSTABLE CROSS-OVER FREQUENCY

If the amplifier is to be used as an amplifier for satellite loudspeakers (mid-range/tweeter loudspeakers switch (7) to "HPF". Set the desired cross-over frequency with the control (5). Only the frequencies a set cross-over frequency will then be amplified. This effectively minimizes distortions caused by excessi membrane movement at low frequencies and small satellite loudspeakers without reducing the bass lev

5.4 BASS-BOOST

The bass-boost function (4) is used to increase or equalize the lower bass frequencies.

5.5 OUTPUTS FOR CONNECTING ADDITIONAL AMPLIFIERS

The input signal of the LINE INPUT connections L and R (2) is forwarded directly to the LINE OUT jacks. The LINE OUT connections allow the use of additional amplifiers without requiring additional T-p cables.
