Headroom Notes
Douk publishes something almost nobody in this segment does: a full table of output power against both supply voltage and load impedance. The figures recorded here are the row for the DC 48V/5A adapter the description calls the default - 102 W into 8 ohms, 110 W into 6, 120 W into 4. The 250 W per channel in the same table needs a DC 48V/10A supply, which is not offered as an option for this model.
Thermal Behavior
'Matched speaker impedance: 2-8Ω (Mono) / 4-8Ω (Stereo)'. In stereo the floor is 4 ohms; the 2 ohm figure applies only when the two channels are bridged into one.
Was im Datenblatt tatsächlich steht
Wörtlich von der Herstellerseite zitiert, mit dem Datum der Prüfung. Wir behaupten das Gedruckte, nicht die Absicht dahinter.
«RMS output power in stereo mode: 300W*2（4Ω） … Power Output Table of Douk Audio A100 … DC 48V/5A | 4Ω | 120W+120W»
The specification line and the power table on the same page give different answers for the same load. The line says 300 W per channel into 4 ohms; the table says 120 W per channel into 4 ohms with the DC 48V/5A adapter the description calls the default, and 250 W per channel only with a DC 48V/10A supply. Separately, the cheapest purchase option on that page is 'Without Power Adapter' - the amplifier that the 300 W refers to arrives with no supply at all unless a further fifty dollars is paid.
