KD1540P (Код: )

KD1540P is a high performance digital karaoke processor that allows independent control of audio processing from music sources, microphones and digital effects applied to the voice. It provides several inputs including 2 MICs and 2 stereo analog inputs in addition to Main L/R and 2 outputs selected as Mic, Sub and Left/Right Surround. All of these are managed by the same powerful audio processing used in Marani's professional speaker management systems. The microphone input section offers a complete set of functions for voice processing without modifying its original characteristics. It includes Low/High Shelving filters, 15-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 4th order Low/High-Pass filter and Feedback Eliminator to prevent feedback occurring during the performance. For Microphone source, the KD1540P provides an effects section equipped with professional reverb and delay algorithms that allow the best effect/voice combination to be
obtained through a full set of controls and mixing options. 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 KD1540P include 15-band Graphic Equalizer, Noise Gate and RMS Compressor and 4th order Low/High-Pass filters. In addition a Sub-Harmonics generator allows the sound to be enhanced by generating a copy of the signals in their bass range but shifted an octave lower. Finally a Dynamic filter managed by Mic Section, allows music source level to be controlled according to the amount of voice in the microphone path. The output section provides 4 outputs, each of them including 3-band parametric equalizer, Peak Limiter and Delay up 200ms.

Furthermore the 3th output, selected as MIC, can be used to monitor microphone signal from Pre/Post effects section. The 4th output can be also selected as SUB to drive low-frequency loudspeaker system. The Sub section includes additional filters such as Low Shelving, 3-band parametric 8th order Low/High-Pass, as well as a RMS Compressor. The KD1540P can be connected via USB by using the control remote PC software setting all parameters and creating favorite presets. Moreover it is equipped with wired and infrared remote controls.
