5. 제어 및 연결
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 출력.
- 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. 출력 섹션
- 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.
- 클립 LED: Illuminates when the output signal is clipping, indicating distortion. Adjust the Gain knob down if this LED is consistently lit.
- 원격 포트: RJ11 port for connecting the wired remote bass level control.
Figure 5.3: RCA Output and Remote Port.
5.3. Power and Control Section
- +12V: Main power input (connect to constant +12V from battery).
- 접지: Ground connection (connect to vehicle chassis).
- 렘 인: Remote turn-on input (connect to head unit's remote output or ignition).
- 렘 아웃: Remote turn-on output (provides a 12V signal to turn on an amp리퍼).
- Turn On Mode Switch (AUD, DC, REM): Selects how the unit turns on. 호주 달러 for audio signal detection, DC for DC offset detection on speaker-level inputs, 렘 for traditional remote wire turn-on.
- Ground Isolation Switch (200Ω, ISO, GND): Helps eliminate ground loop noise. 200Ω adds resistance, ISO isolates grounds, 접지 directly connects grounds.
- 전원 LED: 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. 설정 및 설치
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. 장착 위치
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. 배선 연결
- 전원(+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.
- 접지(GND): Connect the GND terminal to a clean, unpainted metal surface on the vehicle's chassis. Ensure a solid, low-resistance connection.
- 원격 입력(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.
- Remote Output (REM OUT): Connect the REM OUT terminal to the remote turn-on input of your amp작성자(들).
- 입력 연결:
- 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 수준): Connect RCA cables from your head unit's preamp outputs to the XBBR2's Low Level Input (L, R) RCAs.
- 출력 연결: Connect RCA cables from the XBBR2's Output (L, R) RCAs to your amplifier의 입력.
- 원격 베이스 컨트롤: 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
- 로드 선택: Start with 20KΩ. If your factory radio shuts down or experiences issues, try 60Ω or 20Ω.
- 켜기 모드: 선택하다 렘 if using a dedicated remote wire. If using speaker-level inputs without a remote wire, try 호주 달러 (audio detection) or DC (DC offset detection).
- 접지 절연: Start with ISO. If you experience ground noise (hissing, whining), try 200Ω or 접지 to find the quietest setting.
7. 사용 설명서
Once installed, the XBBR2 allows you to fine-tune your bass response.
- 전원 켜기: Turn on your head unit. The XBBR2's Power LED should illuminate.
- 게인 설정: 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.
- 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.
- 원격 베이스 컨트롤: 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. 유지관리
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.
- 모든 연결부가 단단히 고정되어 있는지 확인하십시오. 배선에 마모나 부식 흔적이 있는지 주기적으로 점검하십시오.
- Do not block the ventilation openings on the unit, if any, to prevent overheating.
9. 문제 해결
If you encounter issues with your XBBR2, refer to the following common problems and solutions:
| 문제 | 가능한 원인 | 해결책 |
|---|---|---|
| 전원 없음(전원 LED 꺼짐) | Blown fuse; loose power/ground/remote connection; incorrect Turn On Mode. | Check in-line fuse; verify all power, ground, and remote wires are securely connected; ensure Turn On Mode switch is set correctly (REM, AUD, or DC). |
| 소리가 출력되지 않음 | Incorrect input/output connections; Gain set too low; amp앰프가 켜지지 않습니다. | Verify RCA and speaker-level connections; increase Gain knob; check amplifier's remote turn-on connection from XBBR2's REM OUT. |
| Distorted Sound (Clip LED constantly on) | Gain set too high; input signal too strong. | Reduce the XBBR2's Gain knob; if distortion persists, check the input signal level from the head unit. |
| Engine Noise / Whining Sound | 접지 루프 문제. | Adjust the Ground Isolation switch (try 200Ω, ISO, or GND) to find the setting that eliminates the noise. Ensure a good chassis ground connection. |
| Factory Radio Shuts Down | Incorrect Load Select setting. | Adjust the Load Select switch (try 20Ω, 60Ω, or 20KΩ) to match your factory radio's requirements. |
