Frequently Asked Questions - NERO WSA OSD Audio
How do I connect the NERO WSA subwoofer to my receiver?
Use a mono RCA cable from the subwoofer pre-out on your receiver to the LFE input on the subwoofer. Alternatively, you can connect speaker wire to the speaker level inputs.
What is the recommended placement for optimal bass?
Place the subwoofer in a corner or along a wall for deeper bass. Avoid placing it in the center of the room. Experiment with placement to minimize nulls.
How do I set the crossover frequency?
Set the crossover to match your main speakers. If your speakers handle down to 80 Hz, set the crossover to 80 Hz. Adjust to taste.
What does the phase switch do?
The phase switch (0/180°) aligns the subwoofer output with your main speakers. Use the setting that produces the most bass at your listening position.
Why is my subwoofer not powering on?
Check that the power cord is securely connected and the outlet is working. If auto-on is enabled, ensure an audio signal is present. If still off, try the manual power switch.
Can I use this subwoofer with a soundbar?
If your soundbar has a subwoofer output, you can connect it. Otherwise, some soundbars allow wireless subwoofer connection, but the NERO WSA is wired only.
How do I clean the subwoofer?
Disconnect power. Wipe the cabinet with a dry soft cloth. Do not use liquids or cleaners. The grille can be vacuumed gently.
What should I do if the subwoofer produces humming noise?
Ensure all connections are tight. Use a grounded outlet. Avoid running audio cables parallel to power cords. If using a long RCA cable, try a shorter one.
Is the subwoofer safe to use in a home theater system?
Yes, it is designed for home theater and music. Follow safety instructions: keep away from moisture, do not overload power outlet, and ensure ventilation.
Where can I find replacement parts or repair service?
Contact OSD Audio customer support for authorized service centers. Some parts like fuse may be user-replaceable; refer to manual.
