Headroom Notes
The analogue-only sibling of the TB10D already in this catalogue. Its own numbered specification list gives '8. Output power: 100W + 100W' with no load named at all, and '3. THD: ≤ 0.5%'; the description above the list gives '100W X 2(4 ohms, 20 Hz - 20 kHz, 0.04% THD)'. The load and band come only from the description, which is why they are recorded from there.
What the datasheet actually says
Quoted verbatim from the manufacturer’s own page, with the date we checked it. We state what is printed, not what anyone intended by it.
«3. THD: ≤ 0.5%; ... 8. Output power: 100W + 100W — against the description above it: '100W X 2(4 ohms, 20 Hz - 20 kHz, 0.04% THD)'»
One page states two distortion figures for the same amplifier, a factor of twelve apart, and states the power once with a load and once without. A reader taking the specification list alone learns neither what load the 100 W refers to nor which distortion limit applies to it.
