DS-48 is a 1U rack type, full programmable 4-iunput/8-output, 24-bit digital audio system processor. The programming is realized by the front panel control and 2x20 character display, and to use a visualized and maneuverable interface.PC system software can be used in a personal computer platform. Function of DS-48 is not limited to crossover, it can also provide signal distribution, gain control, equalization, delay and limiting. DS-48 is a powerful audio processor for fixed installation and live performance with six parametric EQs per input channel, and six parametric EQs per output channel, all of which are + 15dB gain and -30dB attenuation, bandwidth from 0.016oct to 4.0oct. 

1.  4-way signal input, 8-way signal output

2.  96kHz sampling frequency

3.  Using high-performance 24-bit analog converter, and using the current fastest 32-bit floating-point operation chip

4.  Six parametric equalizers per input channel and outpit channel, all of which are + 15dB gain and -30dB attenuation, bandwidth from 0.016oct to        4.0oct.

5.  Each input and output channel is equipped with mute button editing function

6.  The time delay can be selected in milliseconds as a unit of time, from 0 to 1000ms for easy calculation

7.  30 programs can be stored

8.  Could set a password to protect the program

9.  With a pressure limit function, can be adjusted independently control the start and release time

10.  2 lines 20 characters LCD display

11.  Output channels can be arbitrarily selected, there are A, B, C, D four mode output. Each output has + 15dB and -30dB gain

12.  Each output channel is provided with phase selection, that is, positive and negative phase

13.  3 types high and low pass filters (Butterworth, Bessel, Linkwitz-Riley) and 4 types slope options (12, 18, 24, 48 dB / oct)
