The RD VOICE-500 portable set can be used wherever it is required to sound a word or music among smaller and larger groups of people. The set is also suitable for soloists, DJs and the sound system for the sacred ceremony. Thanks to the internal DSP processor, which modifies the band of transmitted frequencies and delays of signals delivered to each of the speakers, it is possible to change such parameters of the active matrix as: beam range, emission direction and beam opening angle. The RD-VOICE-500 is available in two options: Option with a mixer (high and low frequency controls and gain for each input channel) or an option without a mixer. The set consists of a subwoofer and a central speaker consisting of two modules (column A and B). The ability to play in stereo mode, after purchasing a second set.
