Connections:
The SB-1000 offers various connection options. Refer to the rear panel diagram for specific input/output locations.

Figure 3: Rear panel connections and controls.
- Line Level Input (RCA): Connect your receiver's LFE (Low-Frequency Effects) output or stereo pre-out to the subwoofer's LFE or Line Level inputs.
- Speaker Level Input: For receivers without LFE or line-level outputs, connect speaker wires from your amplifier to the subwoofer's speaker level inputs.
- Power Connection: Connect the provided power cable to the subwoofer and a suitable wall outlet.
4. Operating Instructions
Controls:
The SB-1000 features controls on its rear panel for fine-tuning performance:
- Volume: Adjusts the overall output level of the subwoofer. Start with a moderate setting and adjust to blend with your main speakers.
- Low Pass Filter: Controls the upper frequency limit of the subwoofer. Set this to match the low-frequency capabilities of your main speakers, typically between 80Hz and 120Hz. If using a receiver with LFE output, set the subwoofer's low pass filter to LFE.
- Phase: Adjusts the phase of the subwoofer's output relative to your main speakers. Experiment with 0° and 180° to find the setting that provides the most coherent and impactful bass.
SVS Smartphone App:
For advanced control and convenience, download the SVS subwoofer DSP smartphone app. This app allows you to control volume, manage custom presets, and fine-tune various performance parameters from your listening position via Bluetooth connectivity.
5. Maintenance
To ensure the longevity and optimal performance of your SVS SB-1000 Subwoofer, follow these maintenance guidelines:
- Cleaning: Use a soft, dry cloth to wipe the cabinet. Avoid abrasive cleaners or solvents.
- Ventilation: Ensure adequate airflow around the amplifier panel to prevent overheating.
- Environmental Conditions: Keep the subwoofer away from direct sunlight, heat sources, and excessive moisture.
6. Troubleshooting
If you encounter issues with your SVS SB-1000 Subwoofer, consider the following common solutions:
- No Sound: Check all power and audio connections. Ensure the subwoofer is powered on and the volume is not set to minimum. Verify the source device is playing audio.
- Distorted Sound: Reduce the volume level on both the subwoofer and your receiver. Check for loose connections or damaged cables. Ensure the low pass filter and phase settings are correctly configured.
- Weak Bass: Adjust the volume and low pass filter settings. Experiment with subwoofer placement. Ensure the phase setting is optimized for your listening position.
- Humming/Buzzing: Try connecting the subwoofer to a different electrical outlet. Ensure all audio cables are securely connected and not running parallel to power cables.
