Подешавање и инсталација
Правилна инсталација је кључна за оптималне перформансе и безбедност. Пажљиво пратите ове кораке.
1. Место монтаже
Choose a mounting location that provides adequate ventilation and is protected from moisture. Common locations include under seats, in the trunk, or behind panels. Ensure the amplifier is securely fastened to a solid surface.

2. Прикључци за напајање
- Снага (+12В): Connect a heavy-gauge wire (e.g., 8 AWG or larger, depending on total system power) from the amplifier's +12V terminal to the positive terminal of the vehicle's battery. Install an appropriate fuse holder with a fuse (not included) within 18 inches of the battery.
- Уземљење (ГНД): Connect a heavy-gauge wire of the same size as the power wire from the amplifier's GND terminal to a clean, unpainted metal surface of the vehicle chassis. Ensure a good electrical connection.
- Даљинско укључивање (REM): Повежите жицу мањег пречника (нпр. 18 AWG) са ampREM терминал уређаја за напајање на даљински излаз ваше главне јединице. Ова жица укључује ampукључивање и искључивање горионика помоћу ваше главне јединице.
3. Аудио улазне везе
The MICRO4-1500D features RCA inputs for connecting to your head unit's pre-amp излази.

- Connect RCA cables from your head unit's front and rear pre-amp outputs to the corresponding FRONT and REAR RCA inputs on the ampлифиер.
- Тхе amplifier supports input sensitivity from 200mV to 8V.
4. Speaker Output Connections
Повежите звучнике на amplifier's speaker output terminals. The amplifier can operate in 4-channel full-range mode or 2-channel bridged mode.
- 4-канални режим: Connect each speaker to its dedicated positive (+) and negative (-) terminal. Ensure correct polarity.
- 2-Channel Bridged Mode: For higher power output to subwoofers, bridge two channels. Refer to the diagram on the amplifier for specific bridged connections (typically using the positive terminal of one channel and the negative terminal of the adjacent channel). The minimum impedance for bridged operation is 4 ohms.
Рад и подешавања
Once installed, you can fine-tune the amplifier's settings for optimal audio performance.
1. Контрола појачања
The GAIN control adjusts the input sensitivity of the amplifier to match the output level of your head unit. Start with the gain set to minimum (MIN). Gradually increase the gain until you hear distortion, then back off slightly. This is not a volume control; setting it too high can cause distortion and damage to speakers.
2. Crossover Settings (X-OVER)
The MICRO4-1500D features selectable high-pass (HP) and low-pass (LP) filters for each channel pair (FRONT and REAR).
- ЛПФ (нископропусни филтер): When selected, this filter allows only frequencies below the set frequency to pass through. This is typically used for subwoofers. Adjust the FREQ knob to set the desired cutoff frequency (e.g., 50Hz-500Hz).
- ХПФ (Хигх-Пасс филтер): When selected, this filter allows only frequencies above the set frequency to pass through. This is typically used for full-range speakers to prevent them from playing low bass frequencies they cannot reproduce effectively. Adjust the FREQ knob to set the desired cutoff frequency (e.g., 50Hz-500Hz).
- FULL (Full-Range): When neither HPF nor LPF is selected, the amplifier will pass the full audio frequency range.
Experiment with these settings to achieve the desired sound balance and protect your speakers.
