INTRODUCTION DATA 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.

DIP switches 1 through 4 on the rear panel are used to set the Device ID.
Audio Connections The DP11EQ 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.
Input Insert The DP11EQ can be placed directly on a single microphone insert to process the signal for that microphone only. This is a common location for an leveler.
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.
The Shure Program Group The Shure program group contains the main application icon, a Windows Help file, and a Readme file with the most up-to-date information. To launch the application, double-click on the DP11EQ icon. This group will also contain other Shure software stored on your hard drive. Configuring the Computer Serial Port 1. Launch the DP11EQ software. 2. Click on Communications in the main menu bar. 3. Click on the COM port option of the drop-down menu. 4.
Overview Main Control Panel. In the main control panel, there is button for muting the sound. There is also a button for bypassing overall processing, allowing you to hear the unaffected sound. There is also a Processor Select virtual signal path which allows access to the control panels for the separate processes. There is also a Dynamic Gain meter corresponding to the LEDs on the front panel of the DP11EQ. The Connect button accesses any units connected to a computer.
MAIN CONTROLS The top panel contains the main controls for the DP11EQ software. CURRENT DEVICE ID SCENE NAME UNIT NAME STATUS Main Menu. The main menu contains options for connecting, storing and recalling scenes, and networking with other DP11EQs and DFR11EQs. There is also a help file for online assistance. MUTE Button and LED. This button mutes the audio output of the DP11EQ. The LED is red when muted. BYPASS Button and LED. This button removes all processing from the signal path.
DYNAMICS PROCESSOR Dynamic range is the difference between the loudest and quietest levels of an audio signal. Controlling dynamic range plays an important role in good audio quality. Using the DP11EQ Dynamics Processor, you can control the dynamics of a sound system to improve audio quality.
Dynamics Parameters The edit boxes are used to adjust the parameters of each dynamics process. This section gives general definitions of the parameters. See Dynamics Processes for more specific information. THRESHOLD. The Threshold parameter determines the input level at which dynamics processing begins. For the gate and the expander, processing is activated by signal levels below the threshold. The AGC, the compressor, the limiter, and the peak limiter are triggered by signal levels above the threshold.
Dynamics Processes Gate Definition: A gate mutes an input signal when it drops below a user defined threshold. Every sound system has a certain amount of noise or hiss. Some of this noise is in the background (the hissing of air conditioners), and some may be caused by electrical sources affecting the equipment (electromagnetic hum caused by fluorescent lights). This noise and hiss is usually at such a low level that it is drowned out when there is program material present.
AGC Leveler Definition: The AGC leveler (AGC stands for Automatic Gain Control) automatically lowers or raises the signal level for sounds of varying loudness in order to create a more consistent volume. Application: The leveler can be used for podium and lectern microphones, where it is desirable to maintain a constant volume level when the talker may be moving back and forth from the microphone.
Compressor Definiton: A compressor reduces the dynamic level of an input audio signal by an amount determined by the ratio setting (usually less than 10:1). Typically, a compressor has a slower reaction time than a limiter. Application: Compression can be used in order to scale a signal with a wide dynamic range to audio equipment with a smaller dynamic range (amplifier, loudspeaker, tape recorder, etc.).
No Overshoot Peak Limiter Definition: The no overshoot peak limiter has the ratio fixed at infinity to one (∞:1), uses fast time constants and inserts 1 millisecond signal path delay, allowing the gain reduction to act instantaneously, without audible clipping artifacts, once the input level goes above the threshold. With the no overshoot peak limiter, no peaks will pass through the system, yet the harshness of clipping is avoided.
PARAMETRIC EQUALIZER The DP11EQ also contains two parametric equalizers, with up to 11 parametric filters possible. These equalizers can be used for tuning out feedback or other anomalies in the frequency response of the acoustics of a room or sound system. There are high- and low-frequency rolloff/shelf filters, and parametric filters with adjustable frequency, gain, and width. Parametric filters are represented as dots, while the high- and low-frequency filters are represented as squares.
Setting and Adjusting Parametric Filters Point and click on a filter. It will change colors to show that it is selected. Then, drag the filter by the center to the desired frequency and gain. A parametric filter can be used to cut or boost over a desired bandwidth. Notice that each filter dot also has wings with two smaller dots. drag these to adjust the Q, or width, of the filter to affect a smaller or larger bandwidth.
Response Graph This section describes how to use the Response Graph, which displays the frequency response for the DP11EQ. Snapshots A helpful feature of the response graph is the ability to take snapshots of a frequency response curve. A snapshot allows you to view a trace of the original response curve while making changes. This is an effective setup tool.
IN/OUT Meters and Output Control The IN and OUT level meters located next to the response curve graph display the levels of the input and output for the selected equalizer in dB. When the levels indicate OVR (over), the unit is clipping. This is a useful tool for observing net gain for the equalization settings. To compensate, you can use the OUTPUT slider located near the output controls. Raising or lowering this slider will raise or lower the gain of the output.
DELAY There are some potential problems with the arrival of sound in systems utilizing multiple loudspeakers. The DP11EQ Delay is designed to solve two of these problems: remote speaker alignment and phase cancellation.

Setting Delay by Time To access the Delay window, click on the DELAY button in the virtual signal path. Then set the delay in milliseconds, click on the ↑ and ↓ buttons next the Delay box, or type the amount in the box. Setting Delay by Distance Setting delay by distance is very easy, but you should account for air temperature. As the temperature gets hotter the speed at which sound travels increases, so the delay time decreases.
