Орнотуу жана орнотуу

Proper installation is crucial for optimal performance and safety. Ensure all connections are secure and correctly polarized. This amplifier features a Pulse Width Modulated power supply and a Slow Unmute Soft Start Turn-On circuit.

Электр жана жер байланыштары

• GND (жер): Connect to a clean, unpainted metal surface of the vehicle chassis. Ensure a strong, low-resistance connection.
• REM (Алыстан күйгүзүү): Connect to the remote turn-on lead from your head unit. This wire signals the ampУнааңыздын аудио системасын күйгүзүү жана өчүрүү үчүн көтөргүч.
• +12V (Power Input): Connect directly to the positive terminal of your vehicle's battery using an appropriate gauge power cable and an inline fuse (not supplied) located within 18 inches of the battery.

Speaker Connections

The amplifier supports 4, 3, or 2-channel configurations. Connect your speakers to the 'OUTPUT' terminals, observing correct polarity (positive to positive, negative to negative). For bridged mono operation, refer to the specific wiring diagram in the full product manual.

Киргизүү байланыштары

• Жогорку деңгээлдеги киргизүү: For head units without RCA outputs, connect speaker-level signals directly to the high-level input terminals.
• RCA Inputs (CH1, CH2): Connect RCA cables from your head unit's preamp outputs to these inputs. The Preamp RCA outputs also allow you to daisy chain multiple amplifiers for an expanded audio system.

Фузер орнотуу

The amplifier is equipped with two 30A fuses for protection. Ensure these are correctly installed before operation.

Иштетүү башкаруу элементтери

The PX 1000.4 amplifier features several controls to fine-tune your audio output:

• Деңгээл (Мин/Макс): Киргизүү сезгичтигин тууралайт amplifier to match the output level of your head unit. Start at minimum and slowly increase until desired volume is achieved without distortion.
• Sub Sonic (10Hz-40Hz): A filter that removes extremely low frequencies that are inaudible and can cause damage to subwoofers. Adjust to protect your speakers.
• LPF (Low Pass Filter) (40Hz-300Hz): Allows only frequencies below the set point to pass through to the speakers. Useful for subwoofers to reproduce only bass frequencies.
• Бассты күчөтүү (0дБ, 6дБ, 12дБ): Provides an adjustable boost to bass frequencies. Use sparingly to avoid distortion.
• Phase (0°, 180°): Adjusts the phase of the subwoofer output relative to the main speakers. This helps to ensure that bass frequencies from the subwoofer blend seamlessly with the rest of the audio system.
• Remote (MAXX-U-01): Connects to the included remote bass control knob, allowing convenient adjustment of bass levels from the driver's seat.
