Caution
In case you feed your
power external power supply, monitor the power consumption of the
whole system. With regard to the PoE 802.3af capacities and efficiency
of the switched-mode power supplies in the device, the maximum
possible device input is approximately 12 W. An overload of the PoE
source usually results in PoE disconnection and, subsequently,

inactive, no load switched on LED1–3 and OUT1–2 outputs) is up to 2 W.
The maximum power amplifier consumption is determined by the
current loudspeaker volume level and impedance (up to 10 W for a 4 Ω
loudspeaker). The real consumption is typically lower and depends on
the characteristics of the signal to be amplified.
If you intend to connect a considerable load to the OUT1 and OUT2
outputs, make sure that the total input does not exceed the above
mentioned limit (12 W for PoE). If the PoE supply fails to provide
sufficient power for the specific application, use a more powerful
external source to make your device work perfectly.
