Neat and discreet

Easy setup

It's simple to set up the system's transmitter and receiver. Press the Group button on the receiver and it automatically scans for the clearest group and channel. Then just set the transmitter to the same group and channel settings and you're ready to go. You can also set the Group and Channel manually, plus you can run up to 12 systems simultaneously depending on channel availability and RF environment. The transmitter will run up to 14 hours on a pair of AA batteries.

Natural and effective

The PGA31 headworn microphone offers unobtrusive miking for spoken-word applications, while the BLX1 bodypack transmitter completes a light and portable wireless solution. The BLX14/P31 system offers understated appearance and freedom of movement, delivering Shure sound quality in a simple package.

When considering a wireless system, you'll want to pick the frequency band with the least interference from local TV stations.

Features

Overview: The Shure BLX14/P31 Headworn Wireless Microphone System consists of the BLX4 Wireless Receiver, and the PGA31 Headworn Microphone with the BLX1 bodypack transmitter. You can operate up to 12 compatible systems per frequency band (depending upon your region). The system operates on the H8 frequency band (518 to 542 MHz), and has a transmitting range of approximately 300 feet.

BLX4: The BLX4 Single Channel Wireless Receiver features one-touch QuickScan frequency selection to help you find the best open frequency for less interference. You can also manually change the group and channel assignments, if needed. It has an XLR mic output, as well as a 1/4" instrument-level output jack. The BLX4 is simple to set up, and has a microprocessor-controlled internal diversity antenna system. It has two LED indicators: an Audio LED to indicate the strength of the incoming signal (glows green for normal and red for overload), and a Ready LED to indicate the system is ready for use and receiving the transmitter signal. It is powered by the supplied 12-volt DC power supply.

PGA31: The PGA31 Headset Condenser Microphone is an affordable wireless cardioid condenser headset microphone for hands-free speech and vocal performance applications. Its unidirectional cardioid polar pattern provides excellent off-axis rejection for higher gain-before-feedback when used with a stage monitor. The wire-frame headset fits comfortably and securely, and stays put no matter how active the performer. The flexible gooseneck boom lets you adjust the microphone for optimal positioning. The PGA31 comes with two foam windscreens and a clothing clip to keep the cable secure. The 52" cable is terminated by a 4-pin TA4F connector that plugs into the BLX1 bodypack transmitter.

BLX1: The PGA31 is paired with the BLX1 bodypack transmitter. It is powered by 2 "AA" alkaline batteries (included), which provide approximately 14 hours of battery life. The BLX1 has independent group and channel buttons for easy setup. The transmitter has a convenient clip for attaching it to a belt or pocket.

1 question already asked

Do I just need to buy a PA speaker to use this? Does the receiver plug into the PA speaker or how does that work?
