Pronomic P-154E MKII Power Amplifier

The P-152E MKII has enough power to provide sound for smaller events.
I could hardly notice any heat development.
Unfortunately, the 4cm fan, as is 'usual' with such fans, is not exactly quiet and it also does not seem to be temperature-controlled.
There is a 'considerable' crosstalk between the channels, i.e. if there is only a signal on one channel, it cracks and crackles clearly on the other channel (even if the level control there is set to 0).
As soon as there is also a signal there, you don't hear it anymore. (So it seems to be due to the supply voltage ...)
In normal operation with signal on both channels (e.g. stereo) and moderate volume this should not disturb.
Under 'full load' - i.e. driven until shortly before clipping - the built-in buffer capacity seems to be finally insufficient for the Class D amplifier chip.
This is noticeable by a clear loss of sound quality if you want to use the full power - but who normally wants that.
In the low to medium output range I could not detect (i.e. hear) any distortion.
It is therefore better to use this amplifier only with 8 Ohm speakers to avoid this overload effect.
A minus point is for me the wiring of the Speakon sockets. There is the same channel available on each of the sockets on connection pair 1 and 2.
A tapping of both channels via a 4-pin cable is therefore not possible.
Competitor products are often more user-friendly here.
