Hi,

I have double/triple checked the comms leads: 561 coms->DSP L->slave cable->DSP R; and swapped them around. I have checked digital cables. Checked mains cables. LED's are bright.

All turned off and on again several times. Tried RS232 from pc to each speakers with not other connections except power. The PC/cable/software works with 561 with no problems.
