MARANI 4 IN 8 OUT

* The activity of the 4 inputs is displayed by rows of 6 level LEDs plus 1 clip LED, The activity of the 8 outputs is displayed by rows of 5 level LEDs plus 1 clip LED plus 1 Limiter LED. * The unit has 4 analog inputs, 2 stereo digital input, & 8 analog outputs. * Each input & each output has 7 parametric filters. * All the input & output filters can be selected to be Bell, first and second Order Shelvings w/-3dB at cutting Frequency, Symmetrical Shelving w/variable Q, High Pass/Low Pass w/variable Q, first and second Order All Pass(90/180Deg. * Phase rotation at the cutting Frequency), bandpass & notch. * The outputs X-Over section has Butterworth, Lin/Reyl & Bessel filters up to 48dB/Oct or Custom selectable High Pass/Low Pass w/up to 48dB/Oct w/the cascaded Iind Order cells adjustable in Freq & Q. * RMS compressor w/selectable Ratio up to 32:1 & adjustable Soft/Hard Knee. * Output Peak Limiter w/THR in Vp or dBu for the Loudspeakers protection. * The RMS compressor & Peak Limiter's THR can range up to -30dBu. * Each input & output channels have delays up to 850ms, w/steps of 22usec. * Linking functions between inputs & linking functions between outputs are available. * A function is allowing to have ramps closing the output level on parameter changes, when the unit is used as installation unit; this function can be excluded when the unit is used live & it is necessary to perform small changes to the set parameter. * The DPA480 is providing a very powerful Matrix allowing to assign to each output the desired percentage of anyone of the available 4 inputs. * To Each input can be assigned the Analog one, Digital or a Pink/White noise generated by the DPA480 itself & useful for the Loudspeakers tuning/setting during the installations. * The PC Computer Software for the remote control is allowing to connect in net up to 32 units & is allowing to show the phase of the filter setting & to adjust graphically the RMS compressor & the Peak limiter. * A Flash card is available on the DPA480 for storing & recalling presets. * The remote control Software can work through a local USB interface, a RS485 or a TCP/IP net interfaces. * Analog Input 4 x XLR electronically balanced * Analog Output 8 x XLR electronically balanced * Digital Input 1 SPDIF; Gain 0dBu * Minimun Load 150 ohm * THD+N 0.001% at 1kHz 0dBu * S/N >110dBA * Frequency Response 20Hz - 20kHz; -0.5dBu at 20Hz and 20kHz * AD & DA Converters 1x AK5388 24bit, 3x AK4396 24bit-96kHz * DSP & Processing * DSP Engine MARANI M716 * DSP Resolution 24bit (data) x 24 bit (coeff.),54bit accumulation registers, 96 bit precision on intermediate processing data * Parametric Equalization 30 PEQ filters per input; 11 filters per output * Input Gain From -18dB to +12dB by 0.1dBu resolution steps * Output Gain From -18dB to +18 dB by 0.1dBu resolution steps * Filter Type Bell, Shelving, HP/LP, All Pass, Band Pass, Notch Filter * Filter Gain From -15dBu up to +15dBu by 0.5dBu resolution steps * Center Frequency Selectable with a 1Hz resolution step from 20Hz up to 20kHz * Filter Q/BW Bell Type: Q from 0.4 up to 128 in 100 steps * Shelv/Hp/LP Type: Q from 0.1 up to 5.1 in 100 steps * BandPass/Notch Type/ All Pass: Q from 4 up to 104 in 100 steps * Crossover Section HPF/LPF Butterworth 6/12/18/24dB per octave * Bessel 12/24dB per octave * Linkwitz-Riley 12/24/36/48 dB per octave * Internal Noise Generator White/Pink Noise; Level from -40dBu to 0dBu * Input Noise Gate Threshold from -80dBu up to -50dBu * Attack time from 1ms up to 1000ms; Release time from 10ms up to 1000ms * Output Peak Limiter Threshold from 20dBu to -10dBu * Attack time from 1ms up to 900ms; Release time from 0.1sec up to 5sec * Headroom on internal overflow Processes 12dB * Routing Full Matrix Mixing Mode * Input/Output RMS Limiter Threshold from 20dBu up to -10dBu * Ratio 2:1~32:1; Knee: 0~100% * Make up from -12dB to +12dB * Attack time from 5ms up to 200ms;Release time from 0.1 sec up to 3 sec * Delay 480 ms 10.4us increment/decrement steps per input, 270ms 10.4
