A digital system is either 1 or 0, on or off. The quality is FAR increased as a result of the transmissions being more robust. Just look at the quality of DAB compared to standard broadcast for evidence!

Actually VHF transmits further but at the wattage output you get from wireless systems, the VHF/UHF/SHF difference is irrelevant. So that's not the case. The only thing that is of benefit is that the SHF waves of a digital system running at 2.4GHz etc. are far more penetrating and bounce around a lot. This means that the signals are much better in urban or audience environments.
[quote name='crez5150' post='1119535' date='Feb 7 2011, 09:57 PM']generally the low end digital systems such as Line 6, you can really only get 12 systems/channels working at once[/quote]
Digital systems are far more compact in their bandwidth usage. You can get more channels in less frequency space compared to analogue.
[quote name='crez5150' post='1119535' date='Feb 7 2011, 09:57 PM']if you use 2.4/5gig systems on stage you run the high risk of knocking out other networks operating on or near the same frequency banding. not good if your FOH engineer is using wireless control for his line array/main pa speaker controller[/quote]
This is true for all broadcasts, it just so happens that 2.4GHz is used a lot for other applications whereas the bands used by analogue wireless equipment are only occupied by wireless equipment. It just means you have to make sure that you are on an unoccupied channel. And there are enough that this shouldn't be too hard.
So what was that, I failed? I'm not sure that was the politest way you could have put it, especially seeing as you were wrong.
