DF4.4MN Network Digital Matrix Process
● 32 bit DSP process, 48kHZ sampling rate, 24-bit AD/DA convert.● 8X8 core matrix, which includes 4 local input channels, 4 local output channels, 4 Dante input channels and 4 Dante output channels.
● Dante digital audio 4IN/4OUT Network interface (2xRJ-45), using 24-bit precision, the internal can distribute
with the DSP signal’s 4IN/4OUT route.
● Dante's advanced Network synchronization technology, can provide low latency, low shaking rate and high
sampling precision. Can be used in high performance digital media Network audio and video facilities, radio broadcast and sound recording system. It has all advantages of the CobraNet and EtherSound, such as no compress digital audio signal, ensures the good sound quality effect.
● Each analog input channels 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, linkage
adjustment and volume adjustment.
● Output including X-over, 7 band PEQ, Gain, mute, compressor/limiter, phase, delay, linkage adjustment and
volume adjustment.
● 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 can
realize 180º curve adjust, ALLPASS2 can realize 360º 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 can be adjustment for inputs, compressor, limiter, ratio, time can be adjustment
for outputs.
● Maximal delay time 680mS for all output channels.
● Pre setting can copy for every single channel, every channel can do link adjust.
● Every input and output channel frequency response curve situation can be found when you are in any input
and output.
● Intergrated single generator (pink, white noise and 20-20K sine wave, amplitude adjustable).
● Front panel has level indicator for input/output, USB port, power supply, network indicator light. Plug-in
Dante digital audio port at rear panel, can search for all ID in same segment net when connect PC software.
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.
