4. Installazzjoni

Proper installation is crucial for optimal performance and safety. Follow these steps carefully.

4.1 Mounting the XLOC44X

1. Choose a dry, secure location for the XLOC44X unit, away from direct heat sources or moving parts. Ensure adequate ventilation.
2. Use the provided mounting screws to secure the unit to a flat surface.
3. Mount the remote level control in an easily accessible location for the driver, using the provided bracket and screws.

4.2 Konnessjonijiet tal-Wiring

All wiring should be done with the vehicle's battery disconnected.

1. Power (12V): Connect the 12V terminal of the XLOC44X to a constant +12V power source from the vehicle's battery. Use an appropriate fuse (not included) as close to the battery as possible.
2. Art (GND): Connect the GND terminal to a solid chassis ground point in the vehicle. Ensure a clean, paint-free metal-to-metal connection.
3. Input mill-bogħod (REM IN): If using the remote turn-on feature from your head unit, connect the REM IN terminal to the head unit's remote output wire. If using DC offset or audio detection, this connection may not be necessary.
4. Output mill-bogħod (REM OUT): Connect the REM OUT terminal to the remote turn-on input of your aftermarket amplifier(s). This provides a turn-on signal to the amplifier when the XLOC44X powers on.
5. High-Level Speaker Inputs (FL+/FL-, FR+/FR-, RL+/RL-, RR+/RR-): Connect the vehicle's factory speaker wires to the corresponding high-level input terminals on the XLOC44X. Ensure correct polarity.
6. RCA Outputs (FRONT OUTPUT, REAR OUTPUT): Connect RCA cables from the XLOC44X's FRONT OUTPUT and REAR OUTPUT jacks to the corresponding RCA inputs on your aftermarket amplifier(i).
7. Kontroll mill-bogħod tal-Livell: Connect the remote level control cable to the "REMOTE" port on the XLOC44X.

After all connections are made, reconnect the vehicle's battery and proceed to initial setup.

5. Operation and Initial Setup

Once installed, configure the XLOC44X settings for optimal audio performance.

5.1 Turn-On Mode Selection

Figura 5.1.1: The "TURN ON MODE" switch allows selection between DC offset detection (DC) or remote wire input (REM) for automatic power-on.

• DC: Select this mode if your factory head unit provides a DC offset on the speaker outputs when turned on. The XLOC44X will detect this voltage and turn on automatically.
• REM: Select this mode if you have connected a dedicated remote turn-on wire from your head unit to the REM IN terminal.
• Sejbien tal-awdjo: The XLOC44X can also turn on by detecting an audio signal on the high-level inputs. This is often used when neither DC offset nor a remote wire is available.

5.2 Input Mode and Load Select

• INPUT MODE (2CH/4CH): Set this switch based on the number of high-level input channels you are using. If connecting only front speaker signals to drive all four outputs, select 2CH. If connecting both front and rear speaker signals, select 4CH.
• LOAD SELECT (20Ω, 60Ω, 20KΩ): This switch adjusts the impedance presented to the factory head unit. Experiment with these settings if your factory stereo shuts down or exhibits unusual behavior. Start with 20KΩ, then try 60Ω, and finally 20Ω if necessary. This helps prevent the factory system from detecting an incorrect load and shutting off.

5.3 Ground Isolation

• GROUND ISOLATION (GND, ISO, 200Ω): This switch helps eliminate ground loop noise.
  • GND: Direct ground connection.
  • ISO: Isolated ground.
  • 200Ω: Ground through a 200-ohm resistor.
  If you experience engine whine or other noise, try switching between these settings to find the quietest option.

5.4 Aġġustament tal-gwadann

• GAIN (FRONT/REAR): These knobs adjust the output level of the RCA signals. Set them to match the input sensitivity of your aftermarket amplifier(s). Start with the gain at minimum, then slowly increase it until the amplifier's input is properly driven without clipping. The CLIP indicators on the XLOC44X will illuminate if the signal is clipping, indicating that the gain is set too high.

5.5 Low Pass Filter (LPF) and Bass Boost

Figura 5.5.1: The LPF switch and BOOST knob. The LPF can be turned ON or OFF, and the Bass Boost can be adjusted from 0dB to 12dB.

• LPF (ON/OFF): If you are sending the output to a subwoofer amplifier, you may want to engage the Low Pass Filter to only pass low frequencies. For full-range speakers, turn the LPF OFF.
• BOOST (0dB-12dB): This knob adjusts the amount of bass boost applied to the signal. Use sparingly and adjust to taste, ensuring the signal does not clip.

5.6 Remote Level Control

Figura 5.6.1: The RCA output jacks and the dedicated port for the remote bass level control. The remote control allows for convenient adjustment of the output level.

The included remote level control allows you to adjust the output level of the XLOC44X from your listening position. This is particularly useful for controlling subwoofer levels independently.

6. Manutenzjoni

The NVX XLOC44X requires minimal maintenance. Keep the unit clean and free from dust and debris. Periodically check all wiring connections to ensure they are secure. Do not use harsh chemicals or abrasive cleaners on the unit.
