The Samson AirLine Synth True-Diversity Wireless Ear Set System delivers reliable wireless technology to presenters, instructors, entertainers and more. The system includes the AR300 True-Diversity UHF receiver, and AL300 micro beltpack transmitter.

The compact AL300 transmitter features a mini XLR input connection and flip-style face that protects against accidental setting changes. The SE10T Micro-Headset features a low-profile design and the detachable EC10TX cable is ideal in the event of a short or break. A gain control dial and 15dB Pad switch provide flexible level adjustment.

Users can select between 300 UHF frequencies, and infrared wireless syncing between the transmitter and receiver is achieved at the touch of a button. Additional features include a back-lit LCD display XLR and 1/4" phone outputs, microphone and line-level operation, and simultaneous use of up to 11 systems.
