Discontinued - See LM-600 Loudmouth System


The LoudMouth wireless PA speaker is the ideal solution where a hard-wired PA installation is simply impossible, too expensive, or temporary. The LoudMouth allows you to use your portable 2-way radio, base station or mobile radio to deliver live voice messages directly to a PA speaker up to 2 miles away. Professional grade wireless communication 

The LoudMouth radio receiver is small and lightweight (7"H x 5"W x 3"D, 2lbs). It is housed in a rugged, sealed, weather-resistant housing and includes a wall mounting bracket. The radio receiver should be mounted indoors away from the elements.

The indoor /outdoor 5.5 Watts horn speaker provides 95 dB of audio output @ 50 feet, so even in noisy environments you can get your message out loud and clear. The loud PA horn speaker includes a mounting bracket.

The LoudMouth radio receiver with built-in 8 Watts audio power amplifier is available in the VHF 150-165 MHz band and the UHF 450-470 MHz band.

5 Pre-set Volume Output Levels to select from

Each LoudMouth radio receiver and PA speaker combination can be paged individually. Multiple units can be placed throughout a facility, programmed identically, and activated simultaneously as a group.

9 Auto Shut-Off Timer selections (5 seconds to 4 minutes). After receiver is successfully paged, a pre-set timer will begin count down. A valid radio signal must be received within the selected time interval or the receiver will re-set.
