Active Presets list
A dynamic list of active presets maintained by the system that changes as presets are asserted, activated, and deactivated. The presets are listed in priority order. When a preset is asserted or activated, it goes to the top of the list and its parameter values overlay the current working values for the corresponding system parameters. When a preset is deactivated it is removed from the list.
AES3
A standard from the Audio Engineering Society used for the transport of digital audio signals between professional audio devices.
Assert
To "turn on" a Command preset. For Drag Net users, note that "assert" is the equivalent to "recall".
Base Room
A room that cannot be subdivided. A base room can be combined with other base rooms to form new rooms, but the base room itself cannot be broken down any further.
Baseline Preset
Containing the default settings and link activation states for all the processing and control blocks in your system configuration, the Baseline serves as a foundation for your system. It is a Command preset and, therefore, can never be deactivated. Also, unlike other Command presets, the Baseline can never be deleted. It is always there to serve as the default fallback preset when no other presets are active.
Block
A processing or control element available for use in your audio system. You drag and drop I/O and Host Processing blocks from the Processing Workspace palettes to the Processing Map. Most blocks have input and output nodes on them that you use to wire the block into your signal path. Blocks also have properties associated with them that are accessed by double-clicking the block. Some blocks are quite simple while others are very complex.
Command
Has no state. A Command control simply allows you to initiate an action. Unlike a Toggle, you cannot undo a Command. The most common usage of Command controls is to assert a preset.

Control Link
A link between two or more system controls that causes the controls to track one another. The control link contains the link participants, activation state, current value, Link Master designation, and priority.
Control Link Activation State
A user-configurable state that dictates the enabled state of a link. When a link is not Active, it is disabled.
control link priority
Determines what to do when a control is a participant in more than one active control link. The control is only active in the highest priority active link.
control link source
The control that you drag onto the control link target.
control link target
The control onto which you will drop one or more other controls to create a control link. Think of the control link target as a bucket into which you place all the other controls participating in the link.
Control Link Type
The HAL System includes four types of control links (Level, Selector, Toggle, and Command). All controls participating in a control link must be the same type. Level controls, which are generally associated with volume, have a continuous series of states that are represented by a slider. Selector controls allow the end user to select an item from a list. Toggle controls allow you to switch between two states — on or off. A Command control has no state. It simply allows you to initiate an action.
Control Link Value
The value maintained by a control link and shared by all participants in the link. For example, a Level link maintains a Level value, a Selector link maintains a specific selection, and a Toggle link maintains the toggle state (on or off). A Command link has no value.
default gateway
The default gateway is the device that passes network data from the local network to other networks.
DHCP
Short for "Dynamic Host Configuration Protocol," a protocol for assigning dynamic IP addresses to devices on a network.
Digital Remote
Digital Remote (DR) hardware devices, a variety of which are available for your HAL System, provide system users with easy control of volume, audio selection, preset recall, and more—out in the locations where the control is needed.
DNS
Short for Domain Name System, DNS is a directory service that translates domain names or host names into IP addresses.
Downstream
Audio channels on the expansion bus that flow away from the HAL device.
FireWire
A form of connectivity similar to USB, meant to connect peripherals such as MP3 Players and digital cameras to the computer. Legacy HAL Systems used FireWire to connect EXP1 units to the HAL1 device. FireWire operates around 30 times faster than a USB 1.1 connection. FireWire is technically known as IEEE-1394.
Inverted option
An option for a Toggle link participant that, when selected, reverses the behavior of the Toggle control with respect to the link value. When the link's value is true, the participant's value is false (and vice versa).
Level
Generally associated with volume, Level controls have a continuous series of states that are represented by a slider.
Level control
Generally associated with volume, Level controls have a continuous series of states that are represented by a slider.
Link Master
The control link participant that dictates the values of the other link participants when the link becomes active. Pertains to Level, Toggle, and Selector control links only. Command control links do not have a Link Master.
Link Name
A customizable name identifying a particular control link.
MAC address
Media Access Control address - a unique value associated with a network adapter. MAC addresses are also known as hardware addresses or physical addresses. They uniquely identify an adapter on a LAN (local area network).
offline mode
When you are not connected to a HAL device, you are in offline mode.
online mode
When you are connected to a HAL device, you are in online mode.
Paging Scenarios
One or more paging zones treated as a group for paging purposes. Paging Scenarios are defined and named by the designer, who then also assigns specific Scenarios to specific Paging Stations. End users always page into Scenarios.
Paging Zone
A destination for paging input. Paging Zones are the components that make up a Paging Scenario.
Palette
The area on the left side of Halogen's Hardware Workspace and Processing Workspace that contains elements available for use in your audio design. The Hardware Palette contains hardware devices available for use while the Processing Workspace palettes contain blocks and controls available for use.
Participants
The set of controls participating in a control link. A single control can participate in multiple links but can only be active in one link at a time (determined by link priority).
Preset
A snapshot of one or more system blocks (with their parameters set to specific values) that you or an end user can apply to the audio system at any given time - typically for a specific event or purpose.
Preset Control Type
Determines how you and your end users can control the preset. The control type you choose also determines some of the preset's characteristics, which in turn affects control of the preset. There are three preset control types—Toggle, Selector, and Command. Regardless of its control type, each preset accomplishes the same thing—it overwrites the system's current working values with its stored values.
Processing Workspace
The area of the Halogen user interface in which you configure your audio processing, signal flow, and control links.
RaneLink II
A service needed by Halogen to establish a connection with HAL.
Recall
An old term used in the Drag Net product that means to "turn on" a preset. The equivalent term in Halogen is "assert."
Remote Audio Device
Also called a RAD. Primary purpose is to amplify, digitize, and transmit a digital audio signal via CAT 5 cable to a HAL host device. RADs can also receive a digital signal from the HAL and then convert it to analog before sending it to its attached audio equipment. RADs are capable of transmitting and receiving up to four channels of digital audio (two in each direction). To better fit your needs, however, Rane offers various RAD models. Most RAD models are designed to fit in a standard U.S. two, three, or four gang switchbox.
Scratch Pad
A preset feature that, when enabled, tracks and stores changes made to any of the preset values.
Selector
Allows the end user to make a selection from a list. Uses for a Selector control might include selecting a music channel, a preset, a room combination, and so on.
Selector control

static IP addresses
An IP address that does not change. Static IP addresses must be manually assigned to devices.
subnet mask
An IP address has two components, the network address and the host address. A subnet mask separates the IP address into the network and host addresses ([network][host])
Toggle
Allows the user to switch between two states — on or off. A common usage of a Toggle control is to mute/unmute audio. Another common usage is to activate/deactivate a preset.
