N-2.4KP

The N-2.4KP is a cost-effective 2 in 4 out digital speaker processor. It is designed to provide the most suitable audio processing for the low to medium budget cost market as well as controlling the live role. The processor has 2 analog inputs and 4 analog outputs and features a powerful MARANI M704 DSP processor. The machine is equipped with a 24-bit AD / DA converter and each input channel has an 11-band parametric equalizer, gain control, noise gate function, dynamic bass enhancement, RMS limiter, built-in pink/white noise generator and assignable delay. Each output provides up to 7-band parametric EQ filters with slopes up to 48 dB/Oct. Each output channel can be selected with either a peak limiter or RMS limiter and delay. In addition, output channels 1 and 3 are equipped with dynamic loudness filters.
The N-2.4KP supports inputs in full matrix mixing mode, where any output at any ratio may be connected or mixed with the input. The N-2.4KP can be connected via USB or RS485 for remote control. The PC software that gives remote control can control up to 32 units at the same time, and it can show all the parameters and follow the real-time status.
Outstanding performance: 24-bit high-end converter plus 48Hz frequency, with excellent sound quality performance.
2-way input + 4-way output perfect hybrid matrix speaker processor
State-of-the-art DSP processing technology: 11-band equalization filters for each input channel
7-band equalization filters for each output channel
Each band can be selected as Bezier, Schaeffer. Filter slopes range from 6dB/Oct to 48dB/Oct, including Butterworth, Bezier, and Linquartz-Riley filters.
Highly accurate and omni-directionally adjustable peak limiter and RMS voltage limiter for each output.
Adjustable delay time up to 900ms for input channels and 340ms for output channels.
Computer Network Connection: Each output channel can be directly connected to a computer/network, the USB interface on the rear panel, and computer connection communication, but also available RS485/TCPIP connection to the computer, through the remote PC software to set up, monitor and control the machine.
Control: Front panel LCD display window, knob buttons can be operated on the machine for various functions, the front panel each channel has 7 lights, used to display the output level or display pressure limit.
