3. Safety Information
Observe the following safety precautions during installation and operation:
- Always disconnect the vehicle's battery before beginning any electrical work.
- Ensure proper grounding to prevent electrical hazards.
- Do not expose the DSP to moisture or extreme temperatures.
- Consult a professional installer if you are unsure about any part of the installation process.
- Use appropriate gauge wiring for power and signal connections.
4. Setup and Installation
Proper installation is crucial for optimal performance. This section outlines the steps for physically installing and connecting the DSP.
4.1 Physical Installation
- Choose a dry, well-ventilated location in your vehicle, away from direct heat sources or moving parts.
- Mount the DSP securely using appropriate fasteners to prevent vibration.
- Ensure sufficient space around the unit for air circulation and cable management.
4.2 Wiring Connections
The B2 Audio SixTen DSP features 6 RCA inputs and 10 RCA outputs, along with a power terminal block.
- Power Connection: Connect the power terminal block to a fused 12V constant power source, ground, and a remote turn-on lead from your head unit.
- Input Connections: Connect your audio source (e.g., head unit, auxiliary input) to the RCA input jacks (AUX1-AUX6).
- Output Connections: Connect the RCA output jacks (OUT1-OUT10) to your amplifiers. Each output can be configured for specific channels (e.g., front left, front right, subwoofer).

5. Operating Instructions
The B2 Audio SixTen DSP is primarily controlled via a dedicated mobile application available for iOS and Android devices.
5.1 Bluetooth Connection
- Ensure the DSP is powered on. The "BT" indicator light on the unit should be active.
- On your smartphone or tablet, enable Bluetooth and search for available devices.
- Select the B2 Audio SixTen DSP from the list of devices. Follow any on-screen prompts to complete pairing.
- Open the B2 Audio DSP application. The app should automatically detect and connect to the paired DSP.
5.2 Using the Mobile Application
The application provides a graphical interface for all DSP functions, including:
- Input/Output Routing: Assign specific inputs to desired output channels.
- Equalization (EQ): Adjust the frequency response for each channel using a multi-band equalizer.
- Crossovers: Set high-pass, low-pass, and band-pass filters for each output to direct specific frequency ranges to appropriate speakers.
- Time Alignment: Adjust the delay for each channel to ensure sound from all speakers arrives at the listening position simultaneously.
- Gain Control: Fine-tune the output level for each channel.
- Limiter: Monitor and manage output levels to prevent clipping and speaker damage. The unit features "CLIP L" and "CLIP R" indicators.
- Preset Management: Save and recall multiple audio configurations for different listening preferences or music genres.
Refer to the in-app help or tutorials for detailed guidance on specific tuning parameters.
6. Maintenance
The B2 Audio SixTen DSP requires minimal maintenance to ensure long-term performance.
- Keep the unit clean and free from 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.
- Avoid exposing the unit to extreme temperatures or direct sunlight for extended periods.
- Ensure adequate ventilation around the unit to prevent overheating, especially during prolonged operation.
7. Troubleshooting
If you encounter issues with your B2 Audio SixTen DSP, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No power / Unit does not turn on | Incorrect wiring, blown fuse, insufficient power supply. | Check power, ground, and remote connections. Verify fuse integrity. Ensure vehicle battery is charged. |
| No audio output | Incorrect input/output routing, muted channels, incorrect gain settings, faulty RCA cables. | Verify input source and output connections. Check app settings for muted channels or low gain. Test RCA cables. |
| Distorted audio | Input signal too high, output gain too high, clipping. | Reduce input sensitivity or output gain. Monitor "CLIP L/R" indicators and adjust levels to prevent clipping. |
| Bluetooth connection issues | DSP not in pairing mode, interference, app issues. | Ensure DSP is powered on. Restart the app and your mobile device. Try re-pairing the device. Move closer to the DSP. |
| Unit gets hot | Insufficient ventilation, prolonged high-power operation. | Ensure adequate airflow around the unit. Reduce output levels if operating at maximum for extended periods. |
If the problem persists after attempting these solutions, contact B2 Audio customer support for further assistance.
