What to do if my Velodyne Subwoofer stops working after running at high levels?
If your Velodyne Subwoofer has been running at high levels for a while and seems to have stopped, it's possible that one of its protection circuits has been activated. Usually, it will return to normal once it cools down. If it doesn't, try turning the power off and then back on to reset the unit.
Read and keep all safety and operating instructions for future reference.
Adhere to all warnings on the unit and follow all operating and use instructions.
Avoid water, moisture, heat sources, and ensure proper ventilation for the subwoofer.
Connect to correct power source, protect cords from damage, and do not open the unit.
Unplug when unused for long periods; prevent object/liquid entry into the enclosure.
Refer servicing to qualified personnel; use specified replacement parts for safety.
Unpack carefully, use caution when lifting, save packaging, and record serial number.
Optimize placement for low frequencies, avoid corners or room center, and consider room acoustics.
Adjust volume, low-pass crossover (40-120Hz), and phase (0°/180°).
Connect via Line-level (LFE, Pre-amp) or Speaker-level inputs as shown in diagrams.
Use shielded phono cables for line-level and quality speaker cables for speaker-level connections.
Clean the unit with a damp cloth; avoid harsh chemicals or abrasives to protect the finish.
Unit features protection against overdrive, overheating, and power line voltage drops for reliability.
Verify power, signal, and control settings before seeking professional service.
Contact a qualified technician for damaged cords, abnormal operation, water exposure, or physical damage.
