General
The Shure BLX14R/PG30 is the rack version of the BLX14/PG30. This means that you can handily mount the BLX4R receiver in the rack of a flightcase with the accessory materials. This system provides you with the usual reliable performances that you have come to expect from Shure. Connect the clear-sounding headset to the robust, light transmitter, after which a connection with the receiver can easily be made. This is a good and affordable choice for public speakers and instructors that need to have their hands free.
The PG30
This headset microphone is especially well suited for active users. The comfortable steel frame allows you to attach the microphone securely and comfortably to your head. The PG30 is a condenser microphone with a gradual and natural frequency response. It makes for a natural reproduction of your voice. The cardioid pickup pattern prevents feedback and filters background noise like that of speakers and air conditioners. With the TA4F connector you can make a secure connection with the beltpack transmitter so that you won't have to worry about the cable coming free.
Ease of use
The BLX4R receiver has two external antennas. It uses diversity which means that it constantly 'checks' which of the two antennas provides the best signal and switches accordingly. The QuickScan function scans for the best available frequency and automatically attunes to it. You only have to enter this frequency into your lightweight beltpack transmitter and a connection is made.
