- Conexiones de entrada: Connect your head unit's audio outputs to the two inputs on the PX2R.
- Conexiones de salida: Connect the six independent outputs to your amplifiers. The PX2R supports up to three ampsalvavidas.
- Conexión de energía: Connect the power input (10-15Vdc) to your vehicle's power supply. Ensure proper grounding.
- Antena: The device includes an external antenna for Bluetooth connectivity.
2.2 Emparejamiento inicial de Bluetooth
To begin tuning, pair your mobile device with the PX2R via Bluetooth. Refer to the dedicated application for detailed pairing instructions.
3. Instrucciones de funcionamiento
The PX2R is primarily controlled via its dedicated mobile application, offering precise and convenient tuning.
3.1 Control de aplicaciones
The mobile application provides a comprehensive interface for all DSP functions. This allows for detailed adjustments to each speaker from the comfort of your vehicle's cabin.
- Ajuste de ganancia: Adjust input and output gain levels. Note that some models may feature a physical gain knob for inputs.
- Igualdad: Utilize the 28-band input EQ and 3-band parametric EQ per channel to fine-tune your audio frequencies.
- Configuración de cruce: Configure crossover points and filter types (Butterworth, Linkwitz-Riley, Bessel) for optimal speaker integration.
- Time Alignment (Delay): Set independent delay for each channel to achieve precise sound stagEn.
- Limitador: Configure threshold, attack, and decay settings for the RMS/Peak Limiter to protect your speakers from over-excursion.
- Mute & Phase: Control individual channel mute and phase inversion.
- Presets: Save and recall up to three 100% configurable memory presets for different audio preferences or vehicle setups.
3.2 Controles físicos
While most adjustments are made via the app, the front panel provides basic navigation and display information.
- Perilla de control: Navigate menus and adjust parameters shown on the display.
- Botones: Access specific functions or navigate through settings.
4. Mantenimiento
To ensure the longevity and optimal performance of your Expert PX2R, follow these simple maintenance guidelines:
- Mantenga el dispositivo limpio y libre de polvo y residuos. Utilice un paño suave y seco para limpiarlo.
- Evite exponer la unidad a temperaturas extremas o humedad.
- Asegure una ventilación adecuada alrededor de la unidad para evitar el sobrecalentamiento.
5. Solución de problemas
If you encounter issues with your PX2R, consult the following common troubleshooting steps:
- Sin energía: Check all power connections, including the main power (10-15Vdc) and ground. Verify the internal fuse (2 A) is intact.
- Sin salida de audio: Ensure all input and output RCA cables are securely connected. Verify channel routing in the application. Check mute settings for all channels.
- Problemas de conexión Bluetooth: Ensure the PX2R is within range of your mobile device. Restart both the PX2R and your mobile device. Re-attempt pairing.
- Sonido distorsionado: Check gain settings for both inputs and outputs in the application. Ensure no channels are clipping. Verify proper impedance matching with connected ampsalvavidas.
- Los botones no responden: If physical buttons are unresponsive, try resetting the device (refer to application for reset function).
