Hi,
we are installing a pair of Beolab5's at a customer's house but are not using a beosystem. The problem we have is that the Beolab5's are the front L and R speaker in a surround setup on a different processor and the other speakers are built into the ceilings.
We have a couple of options (we have set them up as option 1 by the way):
1.) We could just program the crestron to issue an on command and then do a 10 second burst of volume up to syncronise the volume levels (by having them both flat out).
2.) If someone here were to provide us some information about the sync link cable we could directly write to that to control the volume.
Option 1 is a bit hissy, not too bad, but not ideal. Because the volume has to be set every time they are powered on, it would nearly be impossible to set the an accurate calibrated level by IR as it is relative - so the only absolute setpoint is max (and min as well, but that is useless to us...)
Option 2 is far preferred as the sync cable is obviously working in absolute gain level (as opposed to relative). We really need some info on how this cable works. E.g.: Analog Voltage or Digital Serial.
If you know anything we would be extremely appreciative. Specifics would be even more helpful. For example, if it is digital, baudrate 9600N1 etc
Many Thanks,
James.
