Frequently Asked Questions - Beta 8 INFINITY
How do I connect the Beta 8 subwoofer to my receiver?
Use the line-level RCA output from your receiver labeled 'Sub Out' or 'LFE'. Connect with a single RCA cable to the LFE input on the subwoofer. Alternatively, use speaker-level inputs if your receiver lacks sub output.
What is the optimal crossover frequency setting?
Set the crossover based on your main speakers' capability. Typically start at 80 Hz, which is THX standard. Adjust to blend seamlessly, avoiding localization of bass.
Why does my subwoofer not produce sound?
Check power, cable connections, and ensure the subwoofer is turned on. Verify the volume is not at minimum and that the crossover is not set too low. Also check the auto standby feature; it may be in standby mode.
How do I clean the subwoofer?
Unplug the unit and gently vacuum the outer grille using a brush attachment. Wipe the cabinet with a soft dry cloth. Do not use liquid cleaners or expose to moisture.
Can I use the subwoofer in a home theater and music system?
Yes, the Beta 8 is versatile. It enhances both movies and music, providing deep, impactful bass. Use the phase control to align with your main speakers for best integration.
What does the phase switch do?
The phase switch (0° or 180°) adjusts the subwoofer's polarity relative to the main speakers. This ensures that the bass from both are in sync at your listening position, avoiding cancellation.
Is the subwoofer magnetically shielded?
Yes, the Beta 8 is magnetically shielded, allowing placement near televisions and other electronic devices without causing interference.
How should I position the subwoofer in my room?
Place it along the same wall as your front speakers, preferably in a corner or near a wall to reinforce bass. Avoid placing it in the center of the room. Experiment with placement for best response.
What is the maximum power output of the built-in amplifier?
The built-in amplifier delivers 150 Watts RMS, providing powerful and accurate bass for typical home environments.
How can I reset the subwoofer after a thermal shutdown?
If the subwoofer overheats, it will shut off automatically. Unplug it, allow it to cool for 30 minutes, then plug it back and turn it on. Ensure adequate ventilation and do not block the amplifier's heat sink.
