INTRODUCTION

The Shure Model DP11EQ is a single-channel, digital signal processor that combines a comprehensive dynamics processor, two parametric equalizers, and a delay in a single, half-rack enclosure. The DP11EQ can function as a gate, expander, Automatic Gain Control (AGC) leveler, compressor, limiter, and no overshoot peak limiter. All of these features are accessed via the supplied Windows* software. Y ou can connect a computer to set up the unit in a sound system, then remove the computer so no one can tamper with the settings when the unit is left unattended. The DP11EQ is designed for installed sound reinforcement applications: theater, conference rooms, meeting halls, houses of worship, etc.

The DP1 1EQ is a flexible unit which can be used in almost any part of a sound system. It can be placed directly in an input channel’s insert and used as an equalizer solely for that microphone. Or , it can be placed at a mixer subgroup insert, where it can act as a compressor, equalizer , and noise gate for a group of microphones. Or, it can be placed between the mixer and the power amplifier to equalize overall room sound and function as a limiter to protect the loudspeakers from damage due to clipping.

The following diagrams show several typical connections:

Subgroup Insert

Input Insert

NOTE: See Appendix C. for descriptions of cable and connection information.

Main Amplifier

The DP11EQ is most commonly placed between the main output of a mixer and the input of a power amplifier. At the main output, the unit will af fect all input channels. This setup is ideal for using the DP11EQ as a dynamics processor and as an equalizer.

LINE IN

LINE OUT

Subgroup Insert

When using a multiple bus mixer, the DP1 1EQ can be connected to a single subgroup insert. The unit will affect only the channels associated with that subgroup: the other channels will remain unaffected. This is a common set up for dynamically controlling a specific group of signals, for example, a group of vocal microphones.

DP11EQ SOFTWARE

Introduction

This section describes the Windows-based computer interface software which allows you to control the Shure DP11EQ . The software controls a dynamics processor which can operate as a gate, expander, leveler, compressor, limiter, and no overshoot peak limiter. There are parametric equalizers placed before and after the dynamics processor. In addition, there is a digital delay which can add up to 1.3 seconds of delay from input to output.

Minimum Computer Requirements

The following are the minimum requirements to run the Shure DP11EQ software.

S One 486DX 50 MHz IBM*-compatible computer (math coprocessor required) S 2 MB hard drive space S 4 MB RAM S Windows version 3.1x, or greater S 1 available RS-232 serial (COM) port S One RS-232 cable to connect the COM port of the computer to the DB-9
