Product description

DF SERIES  Linear Phase Professional Loud Speaker Processor

Features:

◆ 96KHz sampling frequency, 32-bit 400MHz DSP processor, 24-bit A/D and D/A conversion;

◆Internal dedicated audio capacitance ELNA professional processing chip ADSP-21489

◆ support USB and LAN connection with computer;

◆Delay accuracy 0.001ms, maximum 1000ms, Group delay 5 ms

◆ through the RS485 interface can connect to the third-party central control system,can be connected with up to 250 devices;

◆ without PC, the function can be set and controlled by the function key and coding wheel on the front panel, which is convenient, intuitive and concise;

◆ 24 groups of user programs can be stored in the machine or PC software;

◆ the SYSTEM button of the panel can be used to set the password for panel lock function to, prevent the misoperation;

◆ 2×24 LCD blue backlight display function setting, 5 segments of LED display to show input/output precise digital level meter, mute and edit status;

◆ each input has 16 sections and outputs 8 sections of multi-functional EQ (optional PEQ, LowShelving 2nd,HighShelving 2nd,LowPass 2nd,HighPass 2nd,Notch, AllPass 1st, AllPass 2nd);

◆ the slopes of variable high/low pass IIR All-pass filters can be set, including Bessel and butterworth

can be set to 12dB, 18dB, 24dB, 36dB, 48dB per octave, linkwitz-riley can be set to 12dB, 24dB, 36dB, 48dB per octave;

◆ linear phase filter FIR, support 512 steps, type can be set high pass, low pass, band pass, etc., window function can be set Rect, Kaiser, Hanning, Hamming, Blackman, blackman-harris, etc.

◆ the parameters of the high/low pass filter can be adjusted independently, and has asymmetric frequency division function;

◆ each input/output channel has delay and phase control and mute setting, the delay can reach up to 1000ms, the delay unit has three options: millisecond (ms), meter (m), foot (ft), with 5 steps of x0.001, x0.01, x0.1, x1, x10, etc.

◆ each input/output path has the RMS compression function, the adjustment range is -28db ~20dB, the step diameter is 0.1, and supports SoftKnee function.

◆ input channel can also control gain, noise gate adjustment and select input channel signal (XLR, DANTE, NoiseGenerator).

◆ support channel replication and coordination;

◆ devices with DANTE function support 4 channels of DANTE input and 8 channels of DANTE output, and each channel of DANTE output can be selected for any XLR output;.
