If you run out of outputs on your classic stereo amplifier, the solution is right there.
Stereo, Home cinema, test bench... and many more options, fully programmable and stand alone solution.
If you want to use a 4 way stereo equipment or a home cinema set up you can use the 8 channels powering 100W per channel. 2 extra channels in SPDIF are also available to add deported surround or active speakers or whatever you want
All channels are programmable separately from each other via Sigma Studio software.
Last time we used MeanWell SMPS we ended up enducing lots of RF noise due to EMI radiation. They tested to comply at 80% load, any variation causes them to go outside of specs badly.
Work around was to build all PCB's using 4 layer topology, where top and bottom layer where solid copper for shielding, internal 2 layers are tracks. We also used top layer as heatsink for power components as it was 3mm aluminium plate. Had EMS company to prototype PCB's: http://www.papcb.com/flex-pcb/ they do lots of high tech PCB assemblies.
Alternative is to place SMPS's in separate fully enclosed metal casing and also place filters on in/out wiring to cut the noise.
