Velodyne SPL-800
Verstärkerplatine — repariert.
The Velodyne SPL-800 has two very different failure stories depending on where it was sold. Units exported outside the US often blow their internal fuse repeatedly due to a mismatched fuse rating — a five-minute fix. A genuinely dead unit that keeps blowing fuses even after that's corrected points to the power supply board itself, which needs component-level repair.

- Internal fuse blows repeatedly, especially outside the USPLATINE — WIR BEHEBEN DAS
Velodyne shipped these with a fast-blow fuse rated for US mains voltage, and units exported to 230V markets kept the same fuse — so a normal power-on inrush or a small voltage fluctuation is enough to blow it. This is a fuse-selection issue, not board damage, and the fix is re-fusing with the correct type and rating for your local mains.
- Completely dead even after correcting the fuse — no power at allPLATINE — WIR BEHEBEN DAS
When the fuse isn't the issue, the fault sits in the power supply board itself — most commonly the switching supply or mains transformer, or a dropping resistor in the regulator stage that has overheated and drifted out of spec. This requires component-level or module-level repair, not just a new fuse.
Warum die Originalplatine ausfällt
Velodyne selected the SPL-800's internal mains fuse for US voltage and used a fast-blow type, which turns out to be too sensitive for the normal inrush current these amplifiers draw at power-on — especially on 230V units sold outside the US, where the mismatch shows up as a fuse that blows within weeks of purchase, or immediately after being replaced with an identical part. Switching to a slower, time-delay fuse at a slightly higher current rating (matched to your local mains) resolves this class of failure entirely, and it's not a sign of anything wrong with the board itself.
A separate, less common failure looks similar at first — the unit won't power on — but persists even after the fuse is corrected. That points to genuine hardware failure on the power supply board: the switching supply or mains transformer itself, or a regulator-stage resistor that has overheated and drifted. This class of fault needs the power board diagnosed and repaired or replaced at the module level, and it's worth ruling out the simple fuse-mismatch explanation first before assuming the worst.

Fragen von Besitzern
I bought mine outside the US and the fuse keeps blowing. Is my sub broken?
Probably not in the way you'd think. Velodyne shipped these with a US-spec fuse that's simply too sensitive for many non-US mains supplies. Re-fusing with the correct type and rating for your region usually solves it completely.
I already tried a new fuse and it still won't power on. What now?
That points to a genuine fault on the power supply board rather than a fuse-rating mismatch, and needs proper diagnosis at component or module level. Send it in and we'll confirm exactly what's failed before quoting.
Is Velodyne still around to help with this?
No — Velodyne is no longer operating, which is exactly why component-level repair from an independent bench is the practical path for keeping these subwoofers running.
