A funny thing happened at my last Gig.

We daisy chain 4 floor monitors for my live act without problem on Friday.

The next evening we return to our setup, which was left standing.

We turned on the monitor amp and a like magic we receive a very strong signal from the local radio station.

We found that if we disconnected the last monitor in our daisy chain the signal is reduced but still present.

If we reconnected the last monitor the radio station would return broadcasting strongly over our system.

I have some ideas why but would like to here from others.

What maybe the cause and more important how to prevent it in the future.

Thanks
Ran
