Shure GLXD14/PGA31 GLX-D Digital Wireless Headset System

The Shure’s GLXD14/PGA31 Headset Wireless System includes GLXD1 bodypack transmitter, a PGA31 headset condenser microphone and a GLXD4 receiver. The system operates on the 2.4GHz ISM band using the Z2 frequency band between 2400 and 2483.5MHz. LINKFREQ automatic frequency management is featured in both the GLXD1 transmitter and the GLXD4 receiver. It permits them to scan for the clearest frequency available & allows to link automatically with each other without any requirement of setup from you besides turning both the units on.  With their continuous interference monitoring, both the transmitter and receiver automatically switch to the clearest frequencies available to avoid interference and dropouts. The GLXD1 includes a rechargeable battery pack that provides up to 16 hours of operation on a full charge. The system has a 200' range of operation and can be used with 7 other GLX-D systems simultaneously. 

The PGA31 headset microphone features a cardioid polar pattern, and can be used for speech and other vocal performance.
