Connect Gates Professional Opinion:
From Connect Gates’ perspective, the MP212U is a very strong all-in-one solution combining multi-zone control with multimedia playback. Compared to MP260, it offers more modern playback options (USB / SD / FM), while still maintaining full 6-zone control. It is ideal for projects where both zoning and audio source flexibility are required, such as malls, supermarkets, and large commercial spaces.
