DriveRack Philosophy
DriveRack
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 preamp 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 functions 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.

Front Panel Operation
The DriveRack 4800 is modal in its operation with different types of navigation depending on the mode
that the unit is in. For each of the modes, navigation has been optimized to ensure speed and accuracy.
DriveRack
3.1 - Navigation
The DriveRack 4800 uses three types of navigation to access system attributes and parameters, Matrix
navigation, Scroll navigation, and Page navigation. Some functions require the use of more than one type
of navigation; an example of this is the Edit mode, where a combination of Matrix navigation and Page
navigation are used to access individual parameters in the various processing modules.
Matrix Navigation - This refers to moving around the matrix, field, or grid of processing modules that are
shown on the main preset screen. Matrix navigation relies on the use of the channel and Function buttons to find the desired processing module. For example, if you were in Copy/Paste mode (see Copy/Paste
below) and wanted to copy the parameters of the Input Graphic EQ on Input B, you would simply press
the INPUT B button then the EQ1 button, and the Input Graphic EQ on input B would be highlighted.

Scroll Navigation - This navigation is used in the Utility menus, as well as in storing, recalling and deleting
presets. It is very useful for finding menu offerings that are located within another sub-menu. For example,
the RTA mic pre gain is located within the Gain/Trim sub-menu of the Utility.
Page Navigation - This is the easiest and most common type of navigation within the DriveRack 4800.
Page navigation is used when there are several pages of parameters that need to be accessed. An example of
Page navigation is found in the Compressor editor where there are three pages of parameters and the NEXT
and PREV PAGE buttons are used to move between these pages.
Section 3
3.2 - Modes of Operation
The standard mode of operation of the DriveRack 4800 is Edit Preset (or Edit) mode. This mode is the
gateway to all editing and is the only “location” from which all the other modes can be accessed. This
mode can be returned to from any other mode or menu by pressing the PRESET button. Pressing the
PRESET button returns you to the main preset screen that shows the signal path through the unit and all
the current processing functions. Additionally, this main preset screen in Edit mode is the safe or home
page; all changes to the system (editing, recalling, storing, deleting, etc.) require button presses to access
these menus. The DriveRack 4800 defaults to this screen and mode upon startup, and returns to this mode
when exiting from all the other modes and menus including: Recall Preset, Store Preset, Delete Preset,
Copy/Paste, Utility, Meter, Wizard, and Configuration. These other modes and/or menus are indicated
by either a button with normal text (White on Black), or by a button with reversed text (Black on White).
The function in normal text is the standard mode, accessed by pressing the button, while the function in
reversed text is the alternate mode, and is accessed by pressing and holding the button for more than two
seconds. An example of this is the STORE/DELETE button, where Store Preset is the standard mode that
is found by pressing the button, and Delete Preset is the alternate mode that is accessed by pressing and
holding for more than two seconds.
