A main heading under the Schematic Library that contains virtual Components that perform DSP on audio signals. The Audio Components section is broken down into several sub-categories.
Audio that is constantly delivered over the internet, or intranet and recieved by an end user.
A sub-category of Audio Components under the Schematic Library. Inter-Core Streaming includes LAN and WAN setup components.
A Component is an element of Q-SYS Designer that:
- can be placed in a design,
- has Properties that can be set,
- has a Control Panel,
- has Control Pins, and
- performs a function.
Components are found in Inventory, Snapshots, and the Schematic Library.
A main heading under the Schematic Library containg components that allow you to control other Components in your design. You can write scripts, create custom controls and more.
The connector pins on components in the Schematic that are selected in the component's properties, and display below the body of the component. These connector pins are used to control the value, position, and/or string of a control in the component via another control. They are also used to send the value, string, and/or position to other controls.
A frequency divider. Crossovers are used in speakers to route the various frequency ranges to the appropriate drivers. Additionally, many crossovers contain various filters to stabilize the impedance load of the speaker and or shape the frequency response. Some crossovers contain levels controls to attenuate various parts of the signal.
D-sub connector with 15 pins in two rows. The A indicates the shell size. (Commonly known as DB-15)
A connection that provides both data and analog audio signals using a DE-15 (HD-15) connector and QSC DataPort cable. Also in the names of equipment that uses DataPort connections, including the Q-SYS DataPort card, and QSC DataPort amplifiers.
D-sub connector with 15 pins in three rows. The E indicates the shell size. (Commonly known as DB-15HD)
Dynamic Host Configuration Protocol
Digital Signal Processing
A sub-category of Audio Components under the Schematic Library. Dynamics contains virtual DSP Components that control various dynamic properties of audio signals.
A system that continues operation, possibly at a reduced level, rather than failing completely, when some part of the system fails.
A sub-category of Audio Components under the Schematic Library. Filters and Equalizers contain virtual DSP Components that control various frequency related aspects of the audio signal.
Field-Programmable Gate Array
A filter that blocks frequencies below the setting, and passes frequencies above the setting.
Used in the metadata Control Pins of the Custom Control component.
1. not accurately determined or determinable
2. imprecise or vague
Inventory is a section in Q-SYS Designer where the proxies for physical hardware used in your sound system are managed. This includes: I/O Frames, amplifiers, Loudspeakers, and more.
The generic name of a resource in the Access Manager Inventory section, or after it has been placed in the Schematic.
A main heading under the Schematic Library. Layout contains components that help you to more efficently organize your design.
The Location is a means by which you can organize your virtual equipment to correspond to your physical equipment.
For example, the Core may be in Rack 1.
Click in the Location property; the " Default Location" is highlighted.
Type the name of the new location. Once you have entered the new Location name, it is available on the pull-down for the Location property for other Inventory devices.
When you have given the location a name, the Core is now displayed under the new location. Any other equipment you identify as being in that location display under that location.
One or more tranducers used in conjunction with an amplifier to produce audio from the electrical output of an amplifer. See transducer.
A sub-category of Audio Components under the Schematic Library. Loudspeaker Stuff contains the Loudspeaker Custom Voicing and the Loudspeaker Monitor Components.
A filter that blocks frequencies above the setting, and passes frequencies below the setting.
A component of an audio system used to mix (combine) multiple inputs into one or more outputs.
A sub-category of Audio Components under the Schematic Library. Mixers contains three DSP Components that mix and control multiple audio signals.
The number of switches there are between to Q-SYS system nodes.
A sub-category of Audio Components under the Schematic Library. The Paging section contains DSP components used in setting up a paging system.
root mean squared - the square root of the arithmetic mean of the squares of a set of numbers
A Schematic Element is the generic name for any resource after being placed in the schematic. This includs components, Inventory items, Snapshots, and so on.
A Schematic Element that enables you to recieve digital or analog audio signals, control signals, and DataPort signals from a Signal Link Transmitter, maybe on another Schematic page, and connect those signals to their normal connections. In short, a graphical "wireless" connection.
A Schematic Element that enables you to connect digital or analog audio signals, control signals, and DataPort signals to it, then by using a Signal Link Receiver, maybe on another Schematic page you can connect those signals to their normal connections. In short, a graphical "wireless" connection.
An item in the Snapshots section of the left-side pane, it can be a Global Snapshot Bank, or a standard Snapshot Bank. The Global Snapshot records the settings of all the controls in a design, to be recalled when needed. The standard Snapshot Bank contains the settings of user-defined controls that can be recalled for specific events.
A Snapshot is one or more Schematic Elements on which the controls have been set to specific values then added to a Snapshot Bank (a group of Snapshots). In Run mode, when you select a Snapshot from a Snapshot Bank, the controls identified in that bank are set to the values in the Snapshot.
The state of a control can include, a string, a value, and a position. For example, a string "-100dB" a value -100, a position 0. Controls can also have vector values, and metadata. Any or all of these are refered to as the state of a control.
Data recieved by the Q-SYS DataPort card from the amplifiers and subsequently, the loudspeakers connected to it for monitoring of various parameters. The parameters include voltage, current, power, temperature, and more.
A sub-category of Audio Components under the Schematic Library. Test and Measurement contains several DSP Components that you can add to your design to perform various tests.
The time required for a physical quantity to rise from zero to 63.2% of its final steady value. The time required for a physical quantity to fall to 36.8% of its initial value.
Uninterruptible Power Supply
Voltage Controlled Amplifier or Voltage Controlled Attenuator
White noise is a random signal (or process) with a flat power spectral density. In other words, the signal contains equal power within a fixed bandwidth at any center frequency.
