Quality lavalier wireless.
This package includes the Shure BLX4 receiver, the PG185 wireless headset microphone and the BLX1 bodypack transmitter.
The PG185 is an electret condenser microphone for clip-on use with a wireless bodypack transmitter. It comes with a clothing clip for secure placement and an acoustic windscreen that minimizes wind noise in outdoor applications. This is the unidirectional version of the PG185.
The BLX1 bodypack transmitter works with lavalier and headset microphones, and also has an input for guitar. The beltpack features an On/Off hard toggle switch, preferring to eliminate the multi-function push button that is used on some wireless transmitters.
The BLX4 is a half-rack sized wireless receiver built into a rugged, polymer ABS chassis. It features advanced capabilities usually unavailable in wireless systems in this price range.
