Shure GLXD24/SM58: Digital Wireless Vocal System with SM58 Vocal Microphone
Shure GLX Digial wireless operare in the Z2 or 2.4 GHz frequency range.
2.4 GHz Pros
- No license required in any country.
- No interference from local TV stations.
2.4 GHz Cons
- Used for many other wireless services, such as Wi-Fi. Note there are audio mixing boards that use Wi-Fi for remote control.
- Heavy RF traffic in this band can adversely affect the GLX-D performance. Symptoms can be short transmission range, frequent loss of signal, inability to operate multiple GLX-D systems at the same time.
- The human body efficiently absorbs and blocks this frequency. The short 2.4 GHz wavelengths (4.9 inches) make it essential to maintain line-of-sight between the transmitter and the receiver for the most reliable operation.
- Microwave ovens can produce local interference in this frequency band.
- At 2.4 GHz, transmission distance outdoors is typically far less than indoors. Outdoors there is a lack of surfaces to reflect the transmitted signal. Such reflections improve transmission distance indoors. As a general rule, 2.4 GHz waves do not effectively penetrate many types of walls.
NOTE: In theory, it is feasible to simultaneously operate up to eight GLX-D systems in one venue under optimal conditions. However, local interference in the 2.4 GHz band will often reduce this number to four or less.
