System Example D: Connecting stageboxes to a Live console over Blacklight IINote: 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.
- Set the Live console's clock source to Internal (Int), as described in the main section.
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 ).
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:
- Ensure each stagebox is set to clock from MADI, as described in the main section.
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.
- The console will clock the Blacklight Concentrator over the Blacklight connection, which in turn provides clock for each of the stagebox(es) over MADI.
