DA44M 4in/4out Digital Matrix Processor
● 32 bit DSP, 48kHz sampling rate, 24bit AD/DA convert.● Each analog input channel with +48V phantom power, MIC/LINE input gain switchable, MIC input sensitivity adjustable.
● Input including, low-cut, independent feedback inhibition, 5 band PEQ, noise gate, gain, mute, phase, link adjustment and volume adjustment.
● Output including X-over, 7 band PEQ, Gain, mute, compressor/limiter, phase, delay and link. Adjustment and volume adjust.
● All PEQ Gain, bandwidth, frequency continues adjustment. type can be select by PEAK, H-SHELF, L-SHELF, LOW CUT, HIGH CUT, ALLPASS1, ALLPASS2.
● All inputs/outputs can do Matrix, and all the input and output channel name can be changed.
● All the input and output with independent phase curve adjust function, PEQ style choose ALLPASS1 is 180°curve adjust, ALLPASS2 is 360° curve adjust.
● All high cut, low-cut filter type can be select by Butterworth, Link witz-Riley, Bessel, slope can be chosen.
● Noise gate's threshold, time, ratio can be adjustment for inputs, compessor, limiter, ratio, time can be adjustment for outputs.
● Maximal delay time 680mS for all input/output channels.
● Pre settings can copy for every single channel, every channel can do link adjust.
● Every input and output channel PEQ curve adjusting picture can be found when you are in any input and output.
● Inside single generator(pink, white noise and 20~20K sine wave, amplitude adjustable ).
● Front panel has level indicator for input/output ,USB port, power supply, net port indicator light. Plug-in USB port and net port. PC one-button connection easy for user’s operations.
● 21 user presets, device and each preset can be save and recall. Password protection function for high level applications.
● Unique assembly aluminum side plate card slot design, can assemble two identical machines into one standard 1U machine. Also can assemble its side ear to the standard cabinet.
