Hi, the NAPSC is always required for the 282, and then you can choose from Hicap, 2*Hicap or Supercap to provide the main power. So 3 or 4 boxes with 2 or 3 power leads. The 252 doesn’t take the NAPSC, just the Supercap, so 2 boxes with one power lead.
Thanks both. Makes sense. Looks like either a electrician in or a MusicWorks G3. Need more sockets. Worried about losing bass tauntness with blocks though.
