Topic: What are the symptoms when there is to much loss in coaxcable?

Will there be dropouts on all channels at the same time or mostly just some channels?
Clicks and pops?
Shifting channels?
Loud noise.. like when yamaha adatinputs fall out of sync?

Will the error LED indicate if there is to much loss in the cable?
The boost on the madi out, is that factory default on or off?
If always set to boost, any cons with that?
