The Pan Beam PB 04 is a compact, active, digitally controllable line source loudspeaker with Beam Steering technology in an attractive design, developed for high-quality speech and music transmissions. The PB 04 features Pan Audio DSP and network functionalities such as Pan Net, AES/EBU and Dante. The PB 04 can generate a beam so that a targeted sound reinforcement is possible. The beam can be modified by different optimizers (max. SPL, SPL min. sidelobes, min. sidelobes). With the help of digital signal processing, the vertical beam angle and the tilt angle can be precisely aligned to the area to be sounded.
