Орнотуу жана орнотуу
Туура орнотуу сиздин оптималдуу иштешиңиз жана узак мөөнөттүү иштешиңиз үчүн абдан маанилүү ampкөтөргүч. Бул кадамдарды кылдаттык менен аткарыңыз.
1. Монтаждоо орду
Choose a mounting location that is dry, well-ventilated, and secure. Ensure adequate airflow around the amplifier's heatsink. Avoid mounting in direct sunlight or near heat-generating components.
2. Электр байланыштары
Before making any connections, disconnect the vehicle's negative battery terminal. Connect the power, ground, and remote turn-on wires as follows:
- +12V (кубат): Connect a fused power cable directly from the positive (+) terminal of the vehicle's battery to the +12V terminal on the amplifier. The fuse should be located within 18 inches of the battery.
- GND (жер): Connect a ground cable of the same gauge as the power cable to a clean, unpainted metal surface of the vehicle's chassis. Ensure a solid electrical connection.
- REM (Алыстан күйгүзүү): Башкы бирдигиңиздин алыскы чыгышынан алыстан күйгүзүүчү зымды телефондогу REM терминалына туташтырыңыз ampкөтөргүч. Бул зым сигнал берет ampбаш бирдиги менен күйгүзүү жана өчүрүү үчүн көтөргүч.

3. Аудио киргизүү байланыштары
The PB2518 supports both High-Level and Low-Level (RCA) inputs.
- Төмөн деңгээл киргизүү (RCA): For head units with RCA pre-outs, connect RCA cables from the head unit's audio output to the "INPUT" RCA jacks on the ampөмүрлүү.
- High-Level Input (Molex): If your head unit does not have RCA outputs, use the supplied high-level input adapter. Connect the speaker wires from your head unit to the adapter, then plug the adapter into the "HIGH LEVEL" input on the ampөмүрлүү.
4. Speaker Connections
Connect your speakers to the "SPEAKER" terminals on the amplifier. Observe correct polarity (+ to + and - to -). The amplifier is 2 Ohm stereo stable and can be bridged for mono operation.
- Стерео режими: Connect one speaker to the Right (+) and Right (-) terminals, and another speaker to the Left (+) and Left (-) terminals.
- Bridged Mode (Mono): To bridge the amplifier for a single channel (e.g., a subwoofer), connect the speaker's positive (+) terminal to the Right (+) terminal and the speaker's negative (-) terminal to the Left (-) terminal. Ensure the speaker impedance is 4 Ohms or higher when bridged. The amplifier can deliver up to 3000 Watts in bridged mode.

иштетүү Ampөмүрлүү
орнотулгандан кийин, тууралоо ampоптималдуу аудио аткаруу үчүн көтөргүч орнотуулары.
1. Gain Control (Input Level)
The "INPUT LEVEL" (Gain) control matches the amplifier's input sensitivity to the output level of your head unit. Start with the gain set to minimum (MIN). Gradually increase the gain until you achieve a clear, undistorted sound at your desired volume level from the head unit. Avoid setting the gain too high, as this can introduce distortion and potentially damage speakers.
2. Кроссовер орнотуулары
The PB2518 features fully adjustable electronic crossovers to direct specific frequency ranges to your speakers or subwoofers.
- Crossover Mode Switch: Select between "FULL LP" (Full Range / Low Pass) or "HP" (High Pass).
- ТОЛУК: Passes the full audio frequency range to the speakers. Use this for full-range speakers or if your head unit handles crossovers.
- LP (Low Pass): Allows only frequencies below the set point to pass. Ideal for subwoofers. Adjust the "LOW PASS" knob to set the cutoff frequency (e.g., 50Hz-250Hz).
- HP (High Pass): Allows only frequencies above the set point to pass. Ideal for full-range speakers or component speakers to prevent low frequencies from distorting them. Adjust the "HIGH PASS" knob to set the cutoff frequency (e.g., 120Hz-3KHz).
3. Bass Boost
The "BASS BOOST" control allows you to enhance low frequencies (around 50Hz) from 0dB to +12dB. Use this feature sparingly and adjust carefully to avoid distortion or damage to your speakers, especially subwoofers.
4. Power and Protection LEDs
- POWER (жашыл LED): болгондо жарык берет ampкөтөргүч кубат алып, кадимкидей иштеп жатат.
- PROTECT (Кызыл LED): болгондо жарык берет amplifier detects a fault condition (e.g., short circuit, overheating, low voltage). If this LED lights up, immediately turn off your audio system and troubleshoot the issue.
