5. Kontrole i veze

Familiarize yourself with the various controls and connection points on the XBBR2 unit.

Figure 5.1: Labeled Diagram of XBBR2 Inputs and Outputs.

5.1. Input Section

• High Level Input (L+, L-, R+, R-): Speaker-level inputs for connecting directly to a factory radio or amplifier's speaker outputs. These inputs can handle up to 225 Watts.
• Low Level Input (L, R): RCA inputs for connecting to an aftermarket head unit's preamp izlazi.
• Load Select Switch (20KΩ, 60Ω, 20Ω): Adjusts the input impedance to prevent factory radios from shutting down due to sensing an incorrect load.

Figure 5.2: High and Low Level Input Terminals.

5.2. Output Section

• Output (L, R): RCA outputs to connect to your amplifier's input. Provides up to 9.5 Volts of output.
• Gain Knob (Min/Max): Adjusts the overall output level of the processed signal.
• Clip LED: Illuminates when the output signal is clipping, indicating distortion. Adjust the Gain knob down if this LED is consistently lit.
• Remote Port: RJ11 port for connecting the wired remote bass level control.

5.3. Power and Control Section

• +12V: Main power input (connect to constant +12V from battery).
• GND: Ground connection (connect to vehicle chassis).
• REM IN: Remote turn-on input (connect to head unit's remote output or ignition).
• REM OUT: Remote turn-on output (provides a 12V signal to turn on an amplifier).
• Turn On Mode Switch (AUD, DC, REM): Selects how the unit turns on. AUD for audio signal detection, DC for DC offset detection on speaker-level inputs, REM for traditional remote wire turn-on.
• Ground Isolation Switch (200Ω, ISO, GND): Helps eliminate ground loop noise. 200Ω adds resistance, ISO isolates grounds, GND directly connects grounds.
• LED za napajanje: Illuminates when the unit is powered on.

5.4. Bass Restoration Controls

• Wide Knob: Controls the width of the bass restoration frequency band. Adjusts how broad or narrow the restored bass frequencies are.
• Sweep Knob: Selects the center frequency of the bass restoration. Allows you to choose which specific low frequencies are enhanced.

6. Postavljanje i instalacija

Proper installation is crucial for the performance and safety of your XBBR2. It is recommended to have this unit installed by a qualified professional.

6.1. Lokacija montaže

Choose a dry, well-ventilated location away from direct heat sources and moisture. Common locations include under a seat, in the trunk, or behind the dashboard. Ensure there is enough space for wiring and air circulation.

6.2. Ožičenje

1. Snaga (+12V): Connect the +12V terminal to the vehicle's positive battery terminal using an appropriate gauge power wire (e.g., 14-18 gauge). Install an in-line fuse (not included) as close to the battery as possible.
2. uzemljenje (GND): Connect the GND terminal to a clean, unpainted metal surface on the vehicle's chassis. Ensure a solid, low-resistance connection.
3. Daljinski ulaz (REM IN): Connect the REM IN terminal to your head unit's remote turn-on output. If using speaker-level inputs and auto turn-on, this connection may not be necessary.
4. Remote Output (REM OUT): Connect the REM OUT terminal to the remote turn-on input of your amplifier(i).
5. Input Connection:
   • For Factory Radios (Speaker Level): Connect the vehicle's speaker wires directly to the XBBR2's High Level Input terminals (L+, L-, R+, R-). Ensure correct polarity.
   • For Aftermarket Radios (Preamp Nivo): Connect RCA cables from your head unit's preamp outputs to the XBBR2's Low Level Input (L, R) RCAs.
6. Izlazni priključak: Connect RCA cables from the XBBR2's Output (L, R) RCAs to your ampunos korisnika koji želi da ga sačuva.
7. Remote Bass Control: Plug the wired remote bass control cable into the Remote port on the XBBR2. Mount the remote control in an accessible location for easy adjustment.

6.3. Initial Switch Settings

• Load Select: Start with 20KΩ. If your factory radio shuts down or experiences issues, try 60Ω or 20Ω.
• Uključite način rada: Odaberite REM if using a dedicated remote wire. If using speaker-level inputs without a remote wire, try AUD (audio detection) or DC (DC offset detection).
• Ground Isolation: Start with ISO. If you experience ground noise (hissing, whining), try 200Ω or GND to find the quietest setting.

7. Uputstvo za upotrebu

Once installed, the XBBR2 allows you to fine-tune your bass response.

1. Power On: Turn on your head unit. The XBBR2's Power LED should illuminate.
2. Postavite Gain: With your head unit volume at about 75-80% of maximum, slowly increase the XBBR2's Gain knob until the Clip LED briefly flashes on the loudest bass notes. Then, back off the Gain slightly until the Clip LED rarely or never illuminates. This sets the maximum clean output.
3. Adjust Bass Restoration (Wide & Sweep): Play music with a good bass presence.
   • Sweep Knob: Rotate the Sweep knob to select the desired center frequency for bass enhancement. Experiment to find the frequency that best complements your music and speakers.
   • Wide Knob: Adjust the Wide knob to control the bandwidth of the bass restoration. A wider setting will affect a broader range of frequencies around the Sweep point, while a narrower setting will focus on a more specific frequency.
4. Remote Bass Control: Use the wired remote bass level control to adjust the overall bass output from the XBBR2 conveniently from your listening position. This control acts as a master volume for the bass restoration effect.

8. Održavanje

The NVX XBBR2 requires minimal maintenance to ensure long-term performance.

• Keep the unit clean and free of dust and debris. Use a soft, dry cloth for cleaning.
• Ensure all connections remain secure. Periodically check wiring for any signs of wear or corrosion.
• Do not block the ventilation openings on the unit, if any, to prevent overheating.
