Loudspeakers

Q-SYS supports several groups of loudspeaker types.Although the groups are different, the majority of Controls, Properties, and Control pins are identical. In this topic the Controls, Properties, and Control Pins, are listed together, and noted where they differ between loudspeakers. Each loudspeaker needs to be configured based on its model, specific hardware configuration, and venue considerations. The following is a listing of the groups of loudspeaker components available in Q-SYS Designer. For a complete listing, and basic specifications, See Loudspeaker Listing at the end of this topic.

Generic 70/100V Speaker

Q-SYS allows the addition of loudspeakers and/or loudspeaker systems other than those manufactured by QSC. This Generic and Generic 70V/100V (distributed audio) Speaker components allow you to configure Q-SYS to meet the specifications of other, or generic, loudspeakers or loudspeaker systems.

Inline Processing allows you to apply the Intrinsic Correction or Basic Correction settings for a QSC loudspeaker even if you're using an amplifier that is not directly supported by Q-SYS.

Controls

Loudspeaker Status

Control	Function	Default/Range
Status	Displays the current status of the amplifier both in text and color. The following is a list of possible status colors, and some example conditions. OK – Green – (0) – Audio is good, hardware is good. Compromised – Orange – (1) – Audio is good but a redundancy mechanism is active (one LAN down but the other is still up) or a non-fatal hardware problem exists (fans too slow, temperature higher than expected, etc.) Fault – Red – (2) – Audio is not passing, or hardware is malfunctioning or mis-configured (amplifier power off, audio streams broken, wrong type of I/O Card installed, loudspeaker short circuit, etc.) Missing – Red – (3) – A piece of hardware, defined in the design, has not been discovered. Audio is not passing through that piece of hardware. Initializing – Blue – (5) – In the process of firmware, configuration update, and design start. Audio is obviously bad. Not Present – Gray – A virtual component in the design, that is designated as Dynamically Paired, and Not Required ,has no hardware assigned to it.	N/A
Input - Mute	Mutes the input to the loudspeaker. When this mute button is on, the associated channel in the DataPort component indicates muted.	Off / On
Input - Gain (dB)	Sets the gain for the loudspeaker.	Default = 0 Range = -100 to 20
Meter Select	Selects the type of metering for all three meters	Default = Peak Range = RMS or Peak
Monitor - Listen	This is a radio type button and is linked to all other Listen buttons in your design. When this button is engaged: the loudspeaker must have more than one band to have this button. any other Listen button in other loudspeakers that may be engaged is disengaged, all the bands in the selected loudspeaker have the Listen button engaged automatically the Listen buttons for the associated channels in the amplifier are engaged automatically, you can turn on and off any combination of the individual band Listen buttons in the loudspeaker. When this button is not engaged, you can only select one band at a time. You must have the Loudspeaker Monitor component in the Schematic and properly connected to make use of the monitoring capability. NOTE: The Monitor buttons are not linked in Emulate mode. Your design must be in Run mode for the functionality described above to operate. Related Topics	Off / On

When this is engaged, any other Listen button that may be on is disengaged. When engaged, the associated amplifier channel Listen button is automatically engaged. The exception is when the master Listen button for this loudspeaker is on, you can listen to one, all, or any combination of bands in this loudspeaker. You must have the loudspeaker Monitor Component in the Schematic and properly connected to make use of the monitoring capability. Related Topics	Off/On

Custom Voicing ¹	The user-defined name of the Loudspeaker Custom Voicing component that will be used with this loudspeaker (and others using the same voicing) to adjust the loudspeaker voicing. The text entered here must match the text in the Loudspeaker Custom Voicing Component's Custom voicing Property. If you have a loudspeaker that calls out a Custom Voicing that does not exist, Q-SYS displays a message when you load to the Core, or Emulate, indicating the error. The design will not run. If there is a mismatch between the number of bands in the Custom Voicing Component and the loudspeaker, Q-SYS displays a message when you load to the Core, or Emulate, indicating the error. The design will not run.	Any existing Loudspeaker Custom Voicing Component.
Inline Processing	Inline processing allows you to apply the Intrinsic Correction or Basic Correction settings for a QSC loudspeaker even if you're using an amplifier that is not directly supported by Q-SYS. The correction for the QSC loudspeaker is typically accomplished by the connection between Q-SYS and the Dataport or CXD-Q Amplifiers and the selected loudspeaker. With Inline Processing, the correction is accomplished in the Core.	Yes / No
To safely create multiple Generic Speaker Components when the loudspeakers are the same, and are using Loudspeaker Custom Voicing: 1. Add a single Generic Speaker to the Inventory, drag its component into the design 2. Add a Loudspeaker Custom Voicing component to the Inventory, drag its component into the design 3. Duplicate the Generic Speaker Component the desired number of times. This automatically adds Generic Speakers with default settings to the Inventory. 4. Select all of the Generic Speaker components you want to share the same Custom Voicing. Assign the Custom Voicing component to all of the Generic Loudspeakers at once. While you have all the Loudspeaker Status/Control components selected, you may also set the remainder of the loudspeaker properties that match. 5. Run or Emulate the Design and adjust the Loudspeaker Custom Voicing controls as required. All of the loudspeakers that have this Custom Voicing assigned to them are affected.

Loudspeaker Listing

There are three types of correction applied to QSC Loudspeakers when used in conjunction with Q-SYS.

Basic Correction includes band-pass filters, limiters and gains (where applicable) specifically developed for the individual loudspeaker.
Standard Correction includes all the Basic Correction features plus Infinite Impulse Response (IIR) filtering based on the on-axis response.
Intrinsic Correction™ includes all the Basic Correction features plus Finite Impulse Response (FIR) filtering based on the spatially average response – this to make sure the response is as good as it can get at all listening angles.
