Installation et configuration

Montage

Choose a secure, dry location for the EPICENTER Micro, away from direct heat sources and excessive moisture. Ensure adequate ventilation around the unit. The compact size allows for flexible placement options within your vehicle.

Connexions de câblage

• Connexions d'alimentation : Connect the +12V terminal to a constant 12-volt power source, the GND terminal to a solid chassis ground point, and the Rmt In terminal to your head unit's remote turn-on lead. The Rmt Out terminal can provide a remote signal for other components in your audio system.
• Entrées haut-parleurs : If integrating with a factory or aftermarket head unit that only provides speaker-level outputs, connect your vehicle's speaker wires to the designated Speaker Input terminals. The EPICENTER Micro can handle up to 40V input.
• Entrées de ligne : For head units with dedicated line-level (RCA) outputs, connect these to the Line Inputs on the EPICENTER Micro.
• Sortir: Connect the RCA outputs of the EPICENTER Micro to the RCA inputs of your amplifier.
• ACR-4 Remote: Connect the remote cable from the EPICENTER Micro to the ACR-4 dash mount knob.

Configuration initiale

• Sélectionner la charge : Adjust this switch (20Ω, 60Ω, 20kΩ) to match the impedance of your input source for optimal signal transfer and performance.
• Mode de déclenchement: Select the desired turn-on method: Entrée directe (traditional 12V remote), Sens du signal GTO (turns on when an audio signal is detected), or Sens audio (turns on with audio signal).
• Isolation du sol : Use the GND, ISO, or 200Ω settings to eliminate potential ground loop noise. Start with GND and switch if noise is present.
• Volume de sortietage: Sélectionnez le volume de sortie appropriétage (10V+, 7.5V, 5V) to match your amplifier's input sensitivity, preventing clipping and maximizing signal-to-noise ratio.

Opération

Bass Restoration Controls

• Large: This knob adjusts the bandwidth of the bass restoration circuit, determining how broad or narrow the frequency range affected by the bass restoration is.
• Balayage: This knob selects the center frequency for the bass restoration, allowing you to target specific low frequencies for enhancement.
• ParaBASS: This feature acts as a single-band parametric equalizer for the bass output, enabling precise fine-tuning of the restored bass frequencies.

Filtre subsonique PFM

The PFM (Programmable Frequency Match) Subsonic Filter helps protect your subwoofers from ultra-low frequencies that can cause damage or excessive excursion. It can be set to "On" or "Off" (bypassed) depending on your system's capabilities and your listening preferences. Engaging the filter is recommended for most subwoofer applications.

ACR-4 Remote Control

The included ACR-4 dual-knob dash mount remote allows for convenient, independent adjustment of the bass restoration effect level and the overall subwoofer output level directly from your driving position. This enables on-the-fly adjustments to suit different music genres or personal preferences.

Entretien

To ensure the longevity and optimal performance of your EPICENTER Micro, follow these simple maintenance guidelines:

• Keep the unit clean and free from dust and debris. Use a soft, dry cloth for cleaning. Avoid abrasive cleaners or solvents.
• Évitez d'exposer l'appareil à des températures extrêmes, à la lumière directe du soleil ou à une humidité excessive.
• Periodically check all wiring connections to ensure they are secure and free from corrosion. Loose connections can lead to signal loss or noise.

Dépannage

If you encounter issues with your EPICENTER Micro, refer to the following common troubleshooting steps:

• Pas d'alimentation : Verify that the +12V, Ground, and Remote In connections are secure and correctly wired. Check any inline fuses for the +12V power supply.
• Pas de sortie audio : Ensure all RCA and speaker input/output connections are firmly seated. Confirm that the correct Trigger Mode is selected and functioning.
• Distorted Bass: Reduce the 'Wide' and 'Sweep' settings on the unit. Adjust the Output Voltage to match your amplifier's input sensitivity. Ensure the PFM subsonic filter is engaged if your subwoofers are struggling with ultra-low frequencies.
• Noise/Hum: Experiment with the Ground Isolation switch (GND, ISO, 200Ω) to find the setting that eliminates noise. Check for proper grounding of all audio components in your system.
• Basse faible : Increase the 'Wide' and 'Sweep' settings. Ensure the input signal to the EPICENTER Micro is strong enough. Check the settings on the ACR-4 remote control.
