Introduction: Overview and Illustrations

Overview

The DSP-30 and Signal Manager software combine easy-to- use, customizable, two-channel DSP with simple operating- mode selection that requires only two buttons to operate. It can be used with all amplifiers and is housed in a 1-RU , 19-inch rack-mount steel chassis. Sampling frequency is 48 kHz. with 24-bit resolution. Dynamic range is greater than 93dB. It is absolutely rugged and dependable in the spirit of all QSC professional audio products and fully suited for the rigors of touring use.

Processing capabilities of the DSP-30 include compressors, limiters, delays, parametric EQ, high/low pass filters, high/low shelf filters, test signal generators (sine-wave, pink- and white-noise), splitters/mixers, polarity reversal, gain/attenua- tion, and metering. A feature called “Predictive Delay” en- ables the DSP-30’s compressors and limiters to produce less signal distortion than their analog counterparts, especially for fast attack times. Predictive delay adds time delay to the signal path and must be accounted for to maintain proper time allignment. Using the Signal Manager software, predictive delay may be turned on or off; when on, it will provide time delay information to the operator.

The DSP-30 provides powerful signal processing while keep- ing operation as simple. Preset operating modes are user- selectable by scrolling through the list of numbered Presets on the front panel display and selecting. The DSP-30 will mute,

reconfigure, and unmute in a fraction of a second, providing smooth transitions free of thumps, clicks and other undesir- able audio artifacts. The contact closure input feature allows for instantaneous gain changing and other programmable uses.

Use the QSC Signal Manager software to create the preset configurations. Please refer to page 11 for computer system requirements and software installation guidelines. For in- structions for creating a simple signal processing chain, refer to the software help file. QSC’s Signal Manager software provides an easy-to-use graphical user interface where DSP “objects” are placed onto a workspace and interconnects are drawn. This interface allows almost infinite configuration possibilities.

Signal Manager transfers the preset data to the DSP-30 through a serial data cable. The cable connects between the computer’s COM port and the DSP-30’s RS-232 port. Once the presets have been loaded, connection to the computer is no longer required. This feature allows essentially tamper-proof DSP setup. Stored presets can be recalled using the front panel Select button. Modification of stored presets, or the creation of new presets can be implemented by connecting a computer and loading the new presets into the DSP.

The DSP-30 will provide many years of reliable, professional quality signal processing. From all of us at QSC Audio Products, “Thank you.”
