The Graphical User Interface (GUI)
The user interface of the HARVEY mx.16 is characterized by its clarity and simple structures. It allows for intuitive use and enables every user to develop detailed planning layouts for complex projects in only a few steps.
The HARVEY-Composer's key features
- Bundling of parallel lines
- Insertion of signal processing per drag & drop
- Layout with automatic adjustment and right-angled wiring arrangement
- Summing up of logical functions into groups
- Separate layers for audio and control paths
- Hardware processor load in offline mode
- No compiling necessary
The devices to be connected are positioned in the form of inputs and outputs using drag & drop on the working sheet. The number of channels and the channel designations are entered in a query dialogue. The physical inputs and outputs can be allocated to the logical audio paths either manually or automatically at the press of a button.
Inserting audio mixers
Audio mixers and matrixes can be simply added to the project using drag & drop. To do so, the block only has to be dragged put of the library to the desired location. The number of inputs and outputs is given automatically in step 3, when the inputs and outputs are wired to the mixers and matrixes. The matrix is configured in the context menu.
Wiring the Blocks
The inputs and outputs as well as the audio mixer are wired by simply dragging the channel bundles with the mouse. The number of lines contained in a bundle is defined automatically by the source of the cable. Thanks to the right-angled cable structure, the user always maintains absolute clarity even in complex projects and even after years.
Adding signal processing
Ultimately, audio functions can be added from the extensive library by simply dragging the blocks to the desired location on the channel bundle. Existing blocks and cable bundles are then automatically realigned. All audio functions can be configured by a number of parameters and adapted to the application in question.
- AGC: AGC = Automatic Gain Control
- Automixer: Several microphone signals can be mixed to one output signal using the Automixer.
- Cockpit: The Cockpit is the command center for the user interface.
The Cockpit is opened automatically when the program is started. The Cockpit can be accessed at all times with only one a click of the mouse, allowing you to administer projects and communicate with an mx.16 audiomatrix and the network. It is divided into two functional sections for “project administration” and “system communication”.
The Cockpit’s project administration allows you to create, open and save projects. What is more, it also provides a list of the projects last opened.
In the “system communication” section, you can enter network settings and administer systems that are available in the network.
- Configuration: Numerous parameters can be set for the signal processing blocks.
The settings for the individual signal processing functions are done in the parameter dialogue, and can be accessed by double-clicking the respective parameter. Here, you can enter and adjust the different numerical values depending on the function. There are further setting options in the context menu of the blocks.
- Connection editor: The connections between the elements are moved simply by the click of a mouse, while the user is supported by an automatic function. Existing lines are adjusted automatically to any changes.
The blocks are wired very simply with a mouse-click, while the automatic function determines the number of lines, combines these into bundles and arranges them in a rectangular structure. If blocks are moved or new functions added, the audio lines are realigned automatically. The automatic function creates the direct and shortest connection and checks whether a block can be stored at a certain location.
- Control: At the control level, commands from the control interfaces can be evaluated and brought into the audio processing blocks.
- Crossover: Crossover filters make it possible to set up crossover networks.
- Delay: For setting signal delays to equalize runtime differences.
- Ducker: The ducker reduces the signal level on a running program when an announcement is made.
- Dynamics: Dynamic blocks monitor the signal level automatically so that you always have optimally controlled audio signals in different sound transmission situations.
- Equalizer: The prime feature of every audiomatrix is the adjustment of frequency-related signal properties. The user interface together with the mx.16 supplies an extensive set of tools for this purpose.
- Filter: The filter is suitable for high passes and low passes.
- Generator: The generator can create sinus and noise signals.
- Level: Various processing blocks allow level adjustments and measurements.
Level controls adjust the signal level from -00 to +10 dB, enable a 180° phase shift as well as allowing you to parametrize timing parameters for fade in and fade out when calling up preset level values.
Level meters are extremely important for controlling the signal level in online mode while starting up the sound equipment.
Limit switches (level-to-logic) are the connecting elements between audio signal levels and the control level.
- Library: The Library tab page contains all DSP function elements that are needed to create a project.
All available audio functions are displayed clearly in the Library. Inputs and outputs can be moved into the project easily using drag & drop. Levels, mixers and matrixes can be integrated in the same way as filters and EQs or dynamic functions. Delay, stereo differential inputs and generators for sinus and noise are available under “function blocks”.
- Main Window: All display functions and processing tools are integrated in one single, clearly structured main window.
All display functions and processing tools are integrated into one clearly structured main window in the HARVEY-Composer (see above). Libraries, toolbars and context menus are always right in front of you and not distributed among a number of different windows.
The main window consists of four sections:
- Menu bar
- Sidebar with panorama view
- Working sheet
- Status bar
On the menu bar, you can activate the Cockpit, display/print the project protocol, export a project and set several of the HARVEY-Composer properties (incl. graphic transparency, reference gauge, languages German or English).
The sidebar contains library elements of the working sheet for the project. There is also a minimized panorama view of the project working sheet at the bottom of the sidebar.
- Matrices: Matrices allow you to mix, switch and modify audio signal paths.
- Presets: Once the optimum parameters for a certain utilization, for example, podium discussion, have been ascertained, this parameter set can be saved as a preset and accessed at all times.
Presets allow you to change between the different utilization options of an installation. The mx.16 also has “soft” cross-fading between the presets with a time setting. Presets can be created interactively on the working sheet and selected as parameters to be saved. This further simplifies handling as you can preset certain parameter groups.
- Protocol: The HARVEY Composer saves the last work steps in a protocol.
- Project upload and download: Your PC and the mx.16 communicate via a network.
Your PC can be connected to the mx.16 in the system administration of the Cockpit. You also have the option in this online mode of transferring the project you have created into the system. All settings of the audio and control parameters done in online mode are done live and implemented immediately by the device.
- Working sheet: The project is created on the working sheet. All audio functions are displayed in the form of blocks, which are arranged in a grid pattern. The blocks are connected to one another by audio lines which automatically show the correct channel.
To create a project, you first of all have to design the structure of the hardware. The inputs and outputs, mixers and editing functions are moved very simply from the library on to the working sheet per drag & drop. All elements are displayed in the form of blocks and can be connected to audio lines at the click of a mouse.
