MBOX uses new-generation Intel Cedarview-M 32nmAtom dual core processor N2600, which is
recommended to be adopted in built-in industrial control computer. From this design original intention, it is
easy to understand the MBOX pursuit of quality.
Intel N2600 processor’ s extra-low power consumption design enables MBOX a powerful and smooth
computing power while having the aluminum cooling, thus offers listeners a quiet listening status.
MBOX uses onboard non slot DDR3 memory chip, reduces the distances between memory and CPU
utmostly, and eliminates the EMI created by the two.
Power supply is the uppermost priority part of a audio device design, MBOX’ s has no exception.
