Problems are bound to happen sooner or later with wireless microphone and IEM systems. From ever-changing spectrum conditions, to new system upgrades and frequency band changes, the work seems to never end. Here are some strategies for common problems.
Part 3 of our series on spectrum analysis for wireless mics and IEMs: identifying and managing RF interference. Noise floor, out of band interference, IMD, and over-the-air-TV are covered.
Part 2 of our series on RF spectrum analysis for wireless microphones and IEMs, including Operational Scans, what to look for and how to use spectrum analysis to optimize antenna placement.
Part 1 in our series on spectrum analysis for wireless mics and IEMs. Introduction and overview of spectrum analysis and the first steps in using an RF spectrum analyzer to establish a baseline scan for your wireless system.
Using antenna distribution systems with multi-channel wireless mic receivers is covered. Diagrams for how to configure multi-channel systems for lowest noise and highest signal to noise.
Understanding (and measuring!) signal levels and RF link budgets can be the difference between success and failure. In this post we step through the various stages of an RF signal path for a wireless mic system.
I’m pretty sure most understand the need for antenna distribution when using multiple wireless microphone ...
I know, Active sounds better than Passive and more sounds better than less. But with radios, most often, the exact opposite is true. Active antennas are merely passive antennas that have built-in amplifiers intended to make up for loss from long coax runs. Contrary to what some may think, they do not extend range.
Antenna polarization and its effect on wireless microphones. Cross polarization signal fading and multi-path are also covered.
