Hi,
This is from Des which hopefully will help everyone.
Connect SpeakerLink out from processor to SpeakerLink input on the 218.
In addition to the standard SpeakerLink connections, it is necessary to connect the BNC comms output from one of the front speakers (either Master or Slave can be used) to the BNC comms input on one of the “non-218” Slave speakers. Again, it doesn’t matter which one; it might be most convenient to connect one of the front speakers to the centre-channel.
Without this connection, the non-218 speakers won’t follow the front speakers.
Bear in mind that the BNC connection can be made using a basic RCA-to-RCA lead with BNC adapters on each end.
Having the 218 in the signal path introduces a delay which can be dealt with most simply in MConfig as follows…
As the 218 adds 16 milliseconds of delay, the front left and right speakers should be 'moved' 16 feet (4.9 metres) further away in the program. It may feel counter-intuitive, but increasing a distance causes delay to be reduced.
If there is an extreme case where the distances are so big that an additional 16 feet cannot be added, then the same effect can be achieved by 'moving' the “non-218” speakers (centre, sub, and surrounds) 16 feet nearer to the listening position.
I hope this helps,
Richard.
