Great for larger venues to deliver an optimum range of up to 1,500 ft. (457.2m). Offers 17 wide band 100% digital channels - Listen receivers are digitally-tuned so the transmission won’t drift.

Great for schools, houses of worship, stadiums, and courtrooms. Available in 72 MHz only.

    Important FAQ's!
    What is the transmission range of the LS-45-072 system? Up to 1,500 ft. (457.2 m) using universal antenna kit options.
    What is the warranty of Listen transmitters? Limited lifetime warranty. The following cases will void the warranty: Misuse, dropping, or any other noticeable cosmetic damage.
    Is there a limit to the number of transmitters I can use in one room? Yes. The 72 MHz LT-800-072 has a maximum of six.
    Can I purchase additional LR-300-072 receivers for my LS-44-072 system? Yes! Order as many as needed. The additional receivers will need an earphone (LA-164) or any other Listen earphones and batteries before being used.
    What is the warranty of the LR-300? Limited lifetime warranty. The following cases will void the warranty: Misuse, dropping, or any other noticeable cosmetic damage. Charging alkaline batteries instead of NiMH. Overheating the charging process by closing the lid on the charging case.
    How do I lock the SEEK function? Holding SEEK for longer than 4 seconds will lock the receiver on the current channel. When SEEK has been locked, the SEEK function is no longer useable until the same process is achieved to unlock the unit. The LED on the top of the device will blink if the unit is locked and requested to SEEK another channel.
    How do I SEEK for a new channel? If you hold down SEEK momentarily, the receiver will search for the nearest channel in use.
    What is squelching? The purpose of squelch is to mute the audio output of your receiver when the signal from the transmitter is turned off or is too weak to be received. Without squelch you would hear radio noise in your earphone. The squelch function is preset and cannot be changed on the LR-300.
    What is the function of SQ? To reduce noise of our systems, Listen now offers a noise reduction technology called ListenSQ. Both the transmitter and receiver must have SQ on to achieve the desired results. If you are planning to use this product with older Listen systems or equipment not manufactured by Listen, you should disable SQ.
    How many receivers can I have in a system? As many as you need, the number is endless.
    Does this receiver sound as good as your other receivers, which are more expensive? Yes, all Listen receivers have the same superior audio quality (20 dB less hiss than any other competitor).
    What is the difference between the LR-300 and the LR-400 receiver? The LR-400 is more "user friendly" because it has the LCD Display, which will show the channel selection, battery life and signal strength. The LR-400 also has an adjustable squelch setting.
