The Listen LR-400-072 portable receiver utilizes the 57 most common wide band FM channels to give you a big variety of frequencies to choose from, which makes it a great choice for venues that maintain several wireless audio systems or change channels frequently.

With exceptional audio thanks to SQ technology, which provides the highest signal-to-noise ratio available in its category, and full digital tuning to ensure transmission won’t drift, you’re assured that when you select a channel, it stays on that channel – and broadcasts clearly.

The LR400072 features the unique Look & Listen? display. Use it to easily verify channel selection, whether or not channel is locked, battery level, and RF signal strength using the LR-400’s LCD screen! Locking on channel to prevent tampering is as simple as holding down the “SEEK” button for five seconds.

The LR-400-072 broadcasts at 72MHz, which is standard for American wireless systems, and because it utilizes the same channels as most other assistive listening systems, it gives you the flexibility to mix and match with other assistive listening equipment as long as the SQ is disabled. It’s also available at 216MHz (which is required for international use), model LR400216.

A mechanically locking door hides the “Up,” “Down” and “SEEK” buttons to discourage users from tampering with the channel selection.

The LR-400-072 receiver has a line-level earphone jack (3.5mm) that accepts either mono or stereo headsets. The receiver antenna is built into the earphone cord, eliminating additional wires while maximizing its effectiveness. The exclusive built-in belt clip “loop,” located on the back, prevents the unit from slipping off of your belt or strap.

This unit operates on either standard or rechargeable AA batteries. Listen’s unique charging circuitry is conveniently built into the receivers. The built-in SmartCharge does not allow batteries to overcharge, so you’ll never worry about unplugging the transformer at a certain time.

This model has the same exceptional audio quality as Listen’s full-featured LR-500-072. For a compatible transmitter consider the Listen Technologies LT-700-072 bodypack transmitter.

Compatible headsets with the LR-400-072 include the Listen LA-164 ear speaker and the LA-165 stereo headphone.

Please Note: the built-in charging feature can only be used with rechargeable AA batteries and not standard AA batteries.
