System Example D: Connecting stageboxes to a Live console over Blacklight II

Note: When using up to 128 inputs (4 MADI ports), compatibility across both 96 and 48 kHz sample rate operation can be maximised by attaching stageboxes/MADI devices to odd numbered ports. This reduces the requirement to physically re-patch MADI connections and re-route inputs, as the redundant connection scheme will still be valid when even numbered ports are deactivated for 48 kHz operation.
  1. Set the Live console's clock source to Internal (Int), as described in the main Clocking section.
  2. Connect each stagebox MADI port Out & In to an 'A' MADI port on the back of the Blacklight II.MADI Concentrator unit using a pair of 75Ω BNC coax cables (max 75m, conforming to spec defined in the Installation Guide).
  3. If a redundant MADI connection is required, connect each stagebox MADI port 2 Out & In to the corresponding 'B' MADI port on the Blacklight II Concentrator (e.g. stagebox ports 1 & 2 to ports A1 & B1 respectively). Note different connection points for 8- and 16-port Blacklight Concentrators:
  4. Ensure each stagebox is set to clock from MADI, as described in the main Clocking section.
  5. Connect Blacklight Concentrator port A Main (and A Backup if a redundant Blacklight connection is required) to Blacklight port 1a (and 1b if connecting redundantly) on the (Master) console. Console Blacklight ports 2a and 2b may be used for connecting to a second Blacklight Concentrator unit.
  6. The console will clock the Blacklight Concentrator over the Blacklight connection, which in turn provides clock for each of the stagebox(es) over MADI.
