If you haven't heard by now… the Federal Communications Commission (FCC) held an incentive auction to repurpose the 600 MHz UHF TV band (614-698 MHz) which directly affects sound recordists, stadiums, venues, theaters, churches and others using wireless technology.
In the coming months, wireless microphones, in-ear monitors, IFB systems and intercom systems will be forced to adapt to new requirements set by federal regulations prior to the July 13, 2020 deadline. Afterward, only a small portion of the 600 MHz UHF TV band will be available for use.
Thanks to Zaxcom ZHD modulation, the shrinking wireless spectrum just got a whole lot bigger.
Zaxcom High Density (ZHD) modulation is technology that increases the number of channels in the wireless spectrum. There are five different modes to choose from based on your application: Stereo, Mono, XR, ZHD96, and ZHD48.
Finding out how many additional channels you’ll receive with ZHD modulation to any MHz range is simple using a quick formula:
In order to protect against overlapping channels, we subtract 1 to the MHz range. Here are a few examples:
It’s that simple! Now you can face the shrinking wireless spectrum head-on with Zaxcom ZHD modulation.
No matter the application Zaxcom has a solution for your production sound needs.
