Noise

USA page mentions only the 'silent kick unit'; no dB rating

What the manufacturer’s page says about noise, as we read it. It is a statement, not a measurement: no decibel figure is given, and we do not rate noise ourselves.

Caveats from our reading

Manual covers DTX402K/432K/452K together. The 0.5 kg figure on the USA page is the trigger module only.
