2.1 - DriveRack 4800/4820 Philosophy
The philosophy of the DriveRack 4800 and 4820 revolves around the concept of two elements: Attributes and Presets.
Attributes
Attributes are parameters that are global like sample rate, analog I/O gain structure, or RTA microphone pre- amp gain. Most Attributes are found in the Utility menus. Depending on the function, Attributes are either stored instantly as they are changed or upon exiting the Utility menus, and are stored instantly as they are changed.
Presets
A Preset is the name given to the audio processing and routing that is occurring in the DriveRack 4800 or 4820. Up to 50 Presets can be stored in the DriveRack 4800 or 4820. The Preset can be further broken down into two parts: the signal path (or Configuration) and the actual Parameters (listed below) found in the individual processing functions or modules. Presets are stored manually in the DriveRack unit by either using the Store button on the front panel of the 4800 or by using the Preset Tool in the System Architect software. Presets for the DriveRack 4800 or 4820 can also be saved on the PC as a preset file.
Configuration
The DriveRack 4800 and 4820 units offer two types of processing modules. The first type includes func- tions like EQ, Bandpass Filters, Mixers, Routers, and Delay; these functions can be linked together but are fixed in their positions. The second type includes insertable functions that can be selected from a list in four positions; this list includes Feedback Suppression, Compression, Noise Gate, Limiter, Notch Filter, Auto Gain Control, AutoWarmth, etc. The process of linking modules and selecting inserts is called Configuring. The 4800 and 4820 can be configured with hundreds of different signal routing and processing variations.
Parameters
Parameters refers to the processing function parameters. Control of any parameter can be done via the front panel interface of the DriveRack 4800 with its Function and Channel buttons, or the System Architect software. Some parameters, such as output gain, can be adjusted from a ZC series wall panel controller.
System Architect Software / DriveRack Plug-In
The HiQnet System Architect Graphic User Interface application (referred to hereafter as System Architect or GUI) is the control software for the DriveRack 4800 and 4820. In addition to parameter adjustment and all the same control as the front panel of the 4800, System Architect provides the ability to control multiple units. The GUI can save and recall Preset files as well as a Device file that includes all the Presets and Attributes in the unit. Besides these files types, it can also store a venue file with all the units in the network. It can provide a wealth of additional utility like wireless control, grouping functions, custom control panels and more; see Software Operation in Section 4.
