Setup
Placement
The placement of your subwoofer significantly impacts its performance. Experiment with different locations in your room to find the best sound. Generally, placing the subwoofer in a corner can enhance bass output, while placing it closer to your main speakers can improve integration.
Connections
Before making any connections, ensure the subwoofer and all other audio components are turned off and unplugged from the power outlet.
- Power Connection: Connect the supplied power cord to the subwoofer's power inlet and then to a suitable AC wall outlet.
- Audio Connection Options:
- Line Level Inputs (RCA): For receivers or preamplifiers with a dedicated subwoofer output (LFE or Sub Out), connect an RCA cable from the source's subwoofer output to the LFE input on the HRS10. If your source has stereo RCA outputs, use both L and R inputs on the subwoofer.
- Speaker Level Inputs: If your receiver does not have a dedicated subwoofer output, connect speaker wires from your receiver's main speaker outputs to the Speaker Level Inputs on the HRS10. Then, connect your main speakers to the Speaker Level Outputs on the HRS10. Ensure correct polarity (+ to + and - to -).
After making all connections, plug in the power cords and turn on your audio system.
Operating Instructions
Power On/Off
The power switch is located on the rear panel. Set it to the 'ON' position for operation. The subwoofer also features an auto-sensing power mode, which will turn the unit on when an audio signal is detected and off after a period of inactivity.
Adjusting Controls
The HRS10 features several controls on the rear panel to fine-tune its performance:
- Volume: Adjusts the overall output level of the subwoofer. Start with a low setting and gradually increase until the bass blends seamlessly with your main speakers.
- Crossover: This control sets the upper frequency limit for the subwoofer. Adjust it to match the low-frequency capabilities of your main speakers. A common starting point is 80 Hz. If your receiver has a built-in bass management system, set the subwoofer's crossover to its maximum setting or bypass it if possible.
- Phase: The phase control (0° or 180°) helps to ensure that the subwoofer's output is in sync with your main speakers. Experiment with both settings to find the one that produces the most impactful and coherent bass.
Bluetooth Connectivity
The HRS10 supports Bluetooth wireless communication. Refer to your audio source's instructions for pairing and connecting to the subwoofer via Bluetooth for wireless audio streaming.
Maintenance
To ensure the longevity and optimal performance of your Sunfire HRS10 subwoofer, follow these maintenance guidelines:
- Cleaning: Use a soft, dry cloth to clean the cabinet. Do not use liquid cleaners or aerosol sprays, as they may damage the finish or internal components.
- Ventilation: Ensure that the ventilation openings on the subwoofer are not blocked. Adequate airflow is crucial for preventing overheating.
- Storage: If storing the subwoofer for an extended period, disconnect it from power and store it in a cool, dry place, away from direct sunlight and extreme temperatures.
