Hypex SMPS presumes
to radiate very little. Then we have two options:
* Use the aluminum heatsink as
shield.
* Save a certain distance from the modules.
Distance from the SMPS coils. Election choice here.
The
breathing grid is on one side, away from the audio circuitry. It would have been
better if they were small rounded holes so that they would not act like antennas like the narrow, elongated holes.
The
XLR and speaker connectors are already installed in the connector board, so it is assumed that care has been taken to prevent radiations <
150 kHz from entering the wiring. Higher than 150 kHz are those that we have to protect with a good box
(also the f < 150 kHz of course) with
thick aluminum walls.
So if we choose the
star-quad geometry for the external wiring and
metal connectors we will continue betting on excellence. The same could be done with the intern or, at least, add meshes. The one that will radiate the most is the
power cable, which in this case does have a
mesh.
What was said,
they knew very well what they were doing.
Presumably the inlet incorporates a
fuse.
Someone can do "business" about it.
