Karaoke Processors

KD1550P is a high performance digital karaoke processor that allows independent control of audio processing on music sources, microphones and digital effects applied to the voice. It provides several inputs including 3 MICs, 2 stereo analog and 1 digital S/PDIF-Optical in addition to 5 outputs and 2 auxiliary outputs. All of these are managed by powerful MARANI® DSP. The microphone input section offers a complete set of functions for voice processing without modifying its original characteristics. It includes 10-band parametric EQ and Noise Gate in addition to Vocal Exciter function which provides amazing presence and brilliance to the singer’s voice.The input path also features a Feedback Eliminator with intensity adjustable to prevent feedback occuring during the performance.

For Microphone source, the KD1550P provides an effects section equipped with professional reverb and delay algorithms that allows the best effect/voice combination to be obtained through a full set of controls and mixing outputs. Furthermore, the delay section provides 3 independent delays selected as delay time and feedback in order to create particular effects. Looking at the Music input section, the KD1550P include 10-band Graphic Equalizer, Noise Gate and RMS Compressor. The output section provides 5 output, each of them include LP/HP, 4-band parametric equalizer, Peak Limiter and Delay up to 110ms. Furthermore, 2 auxiliary stereo outputs are used tomonitor either microphone signal from Pre/Post effects section or music signal from music input section. The KD1550P can be connected via USB by using the control remote PC SW setting all parameters and creating favorite presets. Moreover, it is equipped with wired and infrared remote control.
