But these are the things that separate great designs from working designs.īack to power supply, we see a coil on the right on the main CPU board. That heat will degrade that cable over time.
Notice that is almost touching the aluminum silver heatsink for the CPU! I have indicated that with a second arrow. The fix would have been dead simple: a slightly longer cable travelling in the front of the CPU board.Īnother miss is where it goes on the CPU board. It is what a computer designer would do that doesn't know audio. This is pretty poor design hygiene for an audio equipment. It goes right over that little board that produces AES/EBU and S/PDIF digital output from the machine!!! That cable is unshielded as power cables usually are so not only could it be carrying noise from the power supply, it can also pick up noise from the computer side and radiate that out onto the digital audio output. The output of the power supply board is that gray cable carrying power to the CPU motherboard on the right.
But whatever it is, it is generating noise. But smack in the middle is a Mean Well (chinese company) 5 volt switchmode power supply! Its input is mains at 120 volts so it will be whaling all out, triggering worries people have about such devices.įrom the low resolution I can't quite tell whether it is there just to power the front panel or the main CPU board. Indeed we see a rectifier and a pair of regulators/transistors on the right. Below the power supply board we see a rather large toroidal transformer leading one to think this devices uses a linear power supply. As shown, the board on the left is the power supply and the board on the right is the computer.
