2 English – INTRODUCTION DA TA The Shure Model DP1 1EQ 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.
3 English – DP1 1EQ HARDW ARE Overview Front Panel DA TA ÊË Ì Í Î Ï Ê BYPASS Button and LED. Press this button to suspend all signal processing from the audio path. When the LED illuminates, the dynamics processor, delay, and the equalizers are bypassed.
4 English – DIP Switches The DIP switches located on the rear panel are used for adapting the unit to the sound system requirements. See the table below .
5 English – Audio Connections 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.
6 English – Input Insert The DP1 1EQ 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 .
7 English – DP1 1EQ SOFTW ARE Introduction This section describes the Windows-based computer interface software which allows you to control the Shure DP1 1EQ . The software controls a dynamics processor which can operate as a gate, expander , leveler , compressor , limiter , and no overshoot peak limiter .
8 English – 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. T o launch the application, double-click on the DP1 1EQ icon. This group will also contain other Shure software stored on your hard drive.
9 English – 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.
10 English – MAIN CONTROLS The top panel contains the main controls for the DP1 1EQ software. UNIT NAME ST A TUS CURRENT DEVICE ID SCENE NAME Main Menu. The main menu contains options for connecting, storing and recalling scenes, and networking with other DP11EQs and DFR11EQs.
11 English – 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 DP1 1EQ Dynamics Processor , you can control the dynamics of a sound system to improve audio quality .
12 English – 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.
13 English – 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.
14 English – 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.
15 English – 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).
16 English – 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.
17 English – P ARAMETRIC EQUALIZER The DP1 1EQ also contains two parametric equalizers, with up to 1 1 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.
18 English – 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.
19 English – Response Graph This section describes how to use the Response Graph, which displays the frequency response for the DP1 1EQ. Snapshots A helpful feature of the response graph is the ability to take snapshots of a frequency response curve.
20 English – 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.
21 English – DELA Y There are some potential problems with the arrival of sound in systems utilizing multiple loudspeakers. The DP1 1EQ Delay is designed to solve two of these problems: remote speaker alignment and phase cancellation.
22 English – Setting Delay by Time T o access the Delay window , click on the DELA Y 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.
23 English – SHURE LINK NETWORKS Shure Link Connections Up to 16 Shure Link devices can be linked together and controlled from a single computer . Each unit comes supplied with one 5-pin DIN cable for linking. DP1 1EQ #1 DP1 1EQ #2 DFR1 1EQ TO COMPUTER LINK OUT LINK IN LINK OUT LINK IN LINK OUT LINK IN 1.
24 English – Shure Link Device Selection In order to access a device in a Shure Link network: 1. Click on Device in the main menu. 2. In the Device menu, click on the desired Device ID.
25 English – Settings Settings for individual panels can be stored separately , as well. Settings are saved on disk with extensions which indicate the settings type: .DYN indicates dynamics, .PEQ indicated parametric equalizer , and .DL Y indicates delay .
26 English – Printing DP1 1EQ Settings If you are documenting a sound system, the DP1 1EQ software offers the option of printing out a hardcopy report showing the settings of a selected unit. T o print out a hardcopy of this report: 1. Click on File in the main menu bar of the Main Control Panel.
