KP24
KP24 is a cost-effective 2 in 4 out of digital speaker processor. Its design concept is to provide the most appropriate sound source processing and control field role for the low budget cost market. The processor has 2 analog inputs and 4 analog outputs, and has a powerful MARANI M704 DSP processor. The machine is equipped with 24 bit AD / DA converter, and each input channel has 11 band parametric equalizer, gain control, noise function, dynamic bass boost function, built-in RMS limiter, pink / white noise generator and a configurable delay. Each output provides a filter with up to 7 band parameter equalization, whose slope is as high as 48dB/Oct. Each output channel can select peak limiter or RMS limiter and delay. In addition, the output channel 1 and the output channel 3 are equipped with dynamic loudness filters.
KP24 supports input in full matrix mixed mode, and any output at any rate may be connected or mixed with input. It can be connected by USB or RS485 to realize remote control. Remote control PC software can control 32 units at most, and can display all parameters, with real-time state.
Outstanding performance: 24 bit high end converter with 48Hz frequency, with excellent acoustic performance
2 way input +4 path output perfect mixed matrix speaker processor
First class DSP processing technology: each input channel has a 11 stage equalizer filter
Each output channel has a 7 stage equalizer filter
Each section can be selected for Bessel schafer. The slope of the filter is from 6dB/Oct~48dB/Oct, including Butterworth, Bessel, Lin Rayleigh - Rayleigh filters
Each output has a high-precision and fully adjustable peak limiter and RMS voltage limiter.
The input channel is adjustable, the delay time is 900ms, the output channel is adjustable, the delay time is as high as 340ms
Computer network connections: each output channel can be directly with the computer / network connection, USB interface panel, connected with the communication and computer, RS485/TCPIP can also connect with the computer, the machine remote monitoring and control software, PC.
Control: the front panel has the LCD display window, the knob button can carry on each function operation to the machine, the front panel each channel has 7 lamps, used to display the output level or display the pressure limit.
