Whether the need is to get an audio signal to an overflow crowd at a special event or send the announcer’s voice across the football stadium, AirLink can get the message across with ease by the use of RF transmission. Tests have been performed through multi-story buildings from lobby to upper conference room, from press box to cross-field component sound systems and various concession booths, or from outdoor program stage to distant Titans with UHF receivers. Transmission distance in excess of 500 feet has been achieved in direct line of sight with absolute clarity and rock solid connectivity. The DR-702D features a digital time delay module which allows the user to synchronize distant audio speakers with the program audio location. The delay module can delay the output signal of the receiver from 20–500 milliseconds. The LCD displays the delay time in milliseconds.
