Changes to operations on frequencies in the 600 MHz

To meet increasing demand for wireless broadband services nationwide, the FCC recently auctioned spectrum that had been licensed to broadcast television stations operating on TV Channels 38-51. The results of the auction (completed in April 2017) will affect the availability of spectrum for wireless microphone operation on the 600 MHz frequencies that correspond to these TV channels, specifically the 614-698 MHz frequencies. Now that the auction is complete, the FCC is requiring nearly 1,000 over-the-air TV stations to change frequencies. These stations will be moving at different times from now through the summer of 2020. If you are using wireless microphone or in-ear systems, these changes will effect the performance of your systems (if it hasn’t already).  This is effecting the entire frequency spectrum we are dealing with every day, including the lower frequencies these stations are moving to. But, rather than bore you with the gory details, just give us a call and we’ll perform a complimentary wireless system analysis for you.  However, if you’re into gory details…

Having cleaner sound without other processors and fewer pieces of gear doing the same thing is incredible. I love the fader bank layouts, input/output patching, and channel flexibility on the SD8, too. The output patching has been particularly beneficial for handling snapshots and sessions. Also the aux send encoders have the flexibility to be assigned to be any channel parameter. The ability to record up to 56 channels on a computer expanded our current setup of a 24-track hard drive, but also eliminated the extra console, too.
