DP4800 is a 1U rack-mounted fully programmed 4-input/8-output 24-bit digital audio system processor. Its program programming is realized through the front panel control and 2X20 character display screen, using a very intuitive and easy-to-guide user interface. The PC system software can be used on a personal computer platform. The role of DSP4.8 is not limited to the frequency divider, it can also provide signal distribution, gain control, equalization, delay and limiting. In short, DP4800 is a powerful audio processor that can be used in fixed installations and live performances. Each input channel is equipped with a 6-band parametric equalizer, and each output channel is equipped with a 6-band parametric equalizer. +12dB gain and -24dB attenuation, Q value from 0.26 to 92.
◆ 4 signal input, 8 signal output
◆ 96kHz sampling frequency.
◆ Using a high-performance 24-bit analog converter, and using the current fastest running 32-bit floating point arithmetic chip.
◆ Each input channel is equipped with 6-band parametric equalizer, and each output channel is equipped with 6-band parametric equalizer, all with +12dB gain and -24dB attenuation, and the Q value ranges from 0.26 to 92
◆ Each input and output channel has an edit button with light mute function.
◆ The delay device can choose milliseconds as the time unit, from 0-100ms, and also choose meters as the length unit, from 0-35 meters, which is convenient for calculation.
◆ 20 programs can be stored.
◆ A password can be set to protect the program.
◆ With pressure limit function, both can independently adjust and control the start attack and release time.
◆ 2-line 20-character LCD display.
◆ The output channel can be arbitrarily selected, there are four output modes: A, B, C and D. Each output has +12dB and -24dB gain.
◆ Each channel has a phase selection, namely positive and negative phase.
◆ Three high and low pass filters (Butterworth, Bessel, Linkwitz-Riley) and three slopes (12, 18, 24dB/oct) are available for selection.
