Rigging Safety Regulations:

• 2006/42/EC

• EN ISO 12100-1: 2004

• EN1991-1 / EN1993-1-1 / EN1993-1-8 / EN1999-1-1

• DGUV Vorschrift 17/18

• ANSI E1.8-2018

General Rules for Suspension

• Consult a professional mechanical or structural engineer, licensed in the jurisdiction of the sound system installation, to review, verify,

and approve all attachments to the building or structure.

• Employ the services of a certiﬁed, professional rigger for hoisting, positioning, and attaching the equipment to the supporting

structure.

• Correct use of all suspension hardware and components is imperative in sound system suspension and deployment.

• Always calculate suspended loads before lifting to ensure suspension components and hardware are used within their respective

load limits.

• Consult local codes and regulations to fully understand the requirements for suspended loads in the venue in which equipment will

be suspended.

• Use only dedicated QSC LA108-AF and/or QSC LA112-AF array frames or the QSC LA-KIT-I installation kit for suspending a

loudspeaker array. Further details can be found below.

• Be absolutely certain of the integrity of any structural member intended to support suspended loads. Hidden structural members can

have hidden structural weakness.

• Never assume anything! Owner or third-party supplied suspension attachment points may not be adequate for suspending the

loads.

• Before lifting, always inspect all components (enclosures, suspension brackets, pins, frames, bolts, nuts, slings, shackles, etc.) for

cracks, wear, deformation, corrosion, missing, loose, or damaged parts that could reduce the strength of the assembly. Discard any worn, defective, or suspect parts and replace them with new, appropriately load-rated parts.

Shock Loading

When a load is moved or stopped, its static weight is magniﬁed. Sudden movements can magnify the static weight several times. This is called "shock loading."

The effects of shock loading can be instantaneous, or it can remain undetected. Proper preparation for shock loading requires careful planning and knowledge of equipment, suspension, and lifting practices. Shock loading is most often the result of lifting and installation, but natural forces (winds, earthquakes, etc.) can create shock loads several times the static load.

Shock loading poses a danger to equipment and workers. Because of this, structures and suspension equipment must be capable of supporting several times the weight of the suspended equipment.

Maximum Suspended Load

The following table provides Working Load Limits (WLL) at varying Safety Factors (7:1, 10:1, or 12:1) for the LA108 and LA112 active line array loudspeakers and companion rigging accessories.

The data presented below is based upon the listed component weights. The tabulated Working Load Limits represent static loads only. Dynamic and shock-load conditions are determined by unknown, installation-speciﬁc factors. The choice of which Safety Factor to follow will depend upon the jurisdiction, venue of installation, and conditions of suspension.

Refer to a Licensed Structural Engineer for clariﬁcation before proceeding with suspension.

Loudspeaker Attachment Points

1. Front Strikes attach to Front Hooks of the loudspeaker or ground stack above it.

2. Front Hooks attach to Front Strikes of the loudspeaker or ground stack adapter below it.

3. Rear Hooks attach loudspeaker at the rear. They are the locking points once two or more enclosures are arrayed together or ground stacked.

4. The Locking Lever has three positions:

• Up: Release loudspeaker from the array

• Middle: Prepare loudspeaker to be secured

• Down: Lock attached loudspeaker in place

Loudspeaker Angle Controls

5. The Angle Lever Reset will release a depressed Angle Lever without adjusting the Angle Bar.

6. The Angle Lever prepares the Angle Bar (7) to move to the next available angle. The Angle Lever must return to the full outward position after angle adjustment. An internal pin locks the Angle Bar when the lever is in the full outward position. If necessary, move the Angle Bar, and/or push the Angle Lever Reset (5) to set the Angle Bar position.

7. The Angle Bar Lift offers manual lifting of the Angle Bar and visual representation of the splay angle setting (Up: 1.5°, Middle: 6°, Down: 12°). Note that the Angle Bar is raised in the LA108 and lowered in the LA112 in the images above.

Understanding Splay Angles

12°

QSC RapidDeploy™ features a unique Angle Bar with an internal pin mechanism that provides three selectable splay angle adjustments. These adjustments allow the user to create custom array shapes based on the venue size and application. These three splay angles are:

• 1.5 degrees - This smaller splay angle setting provides

maximum high frequency coupling between adjacent boxes, delivering the greatest throw:

◦ In a 2-box array this smaller splay angle setting

is ideally suited for large venues or temporary outdoor applications.

◦ In a taller 3-6 box array, this smaller splay angle setting should always be used at the top of the array, which is typically aimed

towards the rear-most section of the audience.

• 6 degrees - This medium splay angle setting provides less high frequency

coupling between adjacent boxes, delivering a moderate throw:

◦ In a 2-box array this medium splay angle setting is ideally suited for

mid-sized venues.

—Figure5—

◦ In a taller 3-6 box array, this medium splay angle setting acts as a

coverage transition and should always be in the center of the array, which is typically aimed towards the middle section of the audience.

• 12 degrees - This larger splay angle setting provides minimal high frequency coupling

between adjacent boxes, delivering a reduced throw:

◦ In a 2 box array this large splay angle setting is ideally suited for small venues or clubs.

◦ In a taller 3-6 box array, this large splay angle setting should be used at the very bottom

of the array, which is typically aimed towards the front-most section of the audience.

Progressive Splay Angle Rule

A larger splay angle value can NOT be used above a smaller splay angle value, as this will result in an unsupported loudspeaker array that cannot be optimized. The splay angle values must either match or progressively increase in size from the top of the array to the bottom. Here is an example of a supported array versus an unsupported array:

NOTE: Although it is technically possible to deploy and use the array using any splay angle combination, which does not follow the Progressive Splay Angle Rule, QSC does not recommend those deployments.

In such cases, the Ar-Q™ Array Equalization and individual loudspeaker EQ can be manually set to taste. In that process, QSC recommends setting all line array loudspeakers to a single loudspeaker voicing because using multiple array equalization settings may cause undesired acoustic results.

How to Manually Total Array Angles

1.5°1.5°1.5°

When hung in an array, loudspeakers require speciﬁc EQs to ensure the array functions properly as a single sound source. The total splay angle of the array is used in part to create the ﬁlter set to make it acoustically accurate. When the array is optimized, the Ar-Q™ Array Equalization DSP relays the total splay angle of the array through infrared communication between the loudspeakers.

In the unlikely event that the infrared stops communicating on one loudspeaker, or when using a deployment that is unsupported by the Ar-Q™ optimization (for example, an array of seven or more loudspeakers), line array voicings can be set manually from the loudspeaker’s Rear User Interface to achieve optimum performance.

To do this, users must calculate the total angle splay BETWEEN loudspeakers in the deployed array and enter that calculation into the DSP to get the correct loudspeaker EQ settings.

NOTE: Do not count the angle between the Array Frame or the Sub Stack Adapter.

NOTE: See the section for “Navigating the Rear User Interface” to access AR-Q™ settings.

Example 1: If an array consists of three (3) loudspeakers deployed with a splay angle of 1.5° between the top and the middle loudspeaker, and 6° between the middle and the bottom loudspeaker, then the total splay angle is 1.5 + 6, which is 7.5 (See graphic below).

Example 2: If an array consists of six (6) loudspeakers, deployed with a splay angle of 1.5° from the ﬁrst to the second loudspeaker,

1.5° from the second to the third loudspeaker, 6° from the third to the fourth loudspeaker, 6° from the fourth to the ﬁfth loudspeaker,

and 12° from the ﬁfth to the sixth loudspeaker, then the total splay angle is 1.5 + 1.5 + 6 + 6 + 12, which is 27 (See graphic below).

Ground Deployment

Pole Mounted on a Tripod Stand

Both LA108/LA112 active line array loudspeakers feature dual 35 mm pole sockets to accommodate either 0° or -7.5° downward tilt of the enclosure to optimize audience coverage wherever deployed.

WARNING!: Due to the large selection of various types of tripod stands available in the market, QSC cannot recommend a maximum deployment height. Assessment of the safety of each individual deployment is left to the user. However, any tripod stands used must be properly rated for the deployment.

WARNING!: When deploying loudspeakers on poles, additional attention should be given to account for environmental conditions such as level surfaces, level materials, vibrations, wind, etc, to deploy the loudspeakers in a stable and safe manner. Use additional measures to secure the loudspeaker pole (not included) when necessary.

LA108 Loudspeaker

Up to three (3) LA108 loudspeakers may be mounted on a 45 kg (100 lb) ratedtripod loudspeaker stand.

LA112 Loudspeaker

Up to two (2) LA112 loudspeakers may be mounted on a 45 kg (100 lb) ratedtripod loudspeaker stand.

Pole Mounting a Loudspeaker to a Tripod

To deploy a pole mount with a tilt of 0° or -7.5°, mount the loudspeaker on a 45 kg (100 lb) rated tripod loudspeaker stand using the 35 mm pole socket labeled 0° or

-7.5° on the bottom of the loudspeaker.

Horizontal Array

There may be situations where very narrow horizontal coverage is required to avoid spillover, such as a stage side-ﬁll or drum monitor. In this application, the LA108/LA112 enclosures can be safely rotated onto their side to create tightly-packed horizontal arrays, which can be seated on a solid base (typically a road-case or a subwoofer).

Rubber feet on either side of the enclosure have been included to prevent side panels from damage.

NOTE: When rotating a LA108 or LA112 onto its side, there is only one correct orientation – with the high frequency waveguide towards the top. An arrow on the rear panel indicates which side of the enclosure the high frequency waveguide is located.

System Power

The LA108 and LA112 loudspeakers' electronic modules do not include a power switch. This is to prevent suspending an array with a loudspeaker's power switch inadvertently bumped off, or left in the off position. To power a loudspeaker on/off, either switch the AC supply at the plug source, or twist the AC POWER-IN connector clockwise or counter-clockwise to power each loudspeaker on/off (ifAC power is connected).

For safety reasons, it is important to follow the proper power cable connection/disconnection sequence to power on or off loudspeakers.

Proper power on/off sequencing can help to prevent undesirable sounds from being introduced into the loudspeaker system (pops, clicks, thumps). Always follow the rule that loudspeakers are “last on, ﬁrst off.”

WARNING!: The LA108 and LA112 loudspeakers employ a universal power supply, capable of operating the system with input AC power voltages ranging from 100 – 240 VAC at 50 – 60 Hz. Make sure to only use the power cable that is appropriate for the deployment location.

AC Mains Connections

The LA108 and LA112 loudspeakers feature dual powerCON TRUE1 AC connectors to support daisy-chaining multiple loudspeakers within an array or for groundstacking deployments.

Neutrik powerCON TRUE1 AC connectors have become standard in the AV production industry and are often found on lighting systems and portable LED walls. The beneﬁts of the powerCON TRUE1 connector are:

• 20 Amp current capacity

• Safe connection/disconnection under load

• POWER-IN and POWER-OUT locking connectors can couple to create extension cables without the need for a separate barrel connector

• IP65 rating for ingress protection (once coupled)

PowerCON TRUE1 AC connectors

—Figure66—

Connecting to AC Mains

1. Insert the locking POWER-IN cable connector of the supplied power cable into the INLET connector on the rear panel.

2. Twist the cable connector clockwise until it locks in place. Twisting the connector also turns power on/off for that box (and any subsequent daisy-chained boxes).

3. Plug the other end of the power cable into the appropriate AC Mains power source.

4. Array will power on automatically once the AC Mains power source is switched on.

Weather-resistant ﬂaps

Daisy-Chaining with Power Cable Jumpers

The LA108 and LA112 loudspeakers feature loop-thru power connection using powerCON TRUE1 connectors. The powerCON TRUE1 cable and connector system is rated for a maximum current draw of 16 amps. In most countries, this is sufﬁcient to power a maximum of six (6) LA108 or LA112 loudspeakers from a single connection to the AC mains supply (see chart below for more details by country voltage).

When not in use, the powerCON INLETS and OUTLETS connectors located on the loudspeakers' rear panel should be covered by the available weatherresistant ﬂaps.

Neutrik powerCON TRUE1 loop-thru cables are not included with LA108 and LA112 loudspeakers but may be purchased separately from most professional audio equipment suppliers or from QSC.

Compatible QSC Accessories

• LA-KIT-J (International Jumper Kit): two 60 cm PowerCon TRUE1 jumpers and two 60 cm EtherCON jumpers,

1.5 mm2/H05VV cables

• LA-KIT-J-NA (North America Jumper Kit): two 24-in PowerCon TRUE1 jumpers and two 24-in EtherCON jumpers, 12 AWG/SVT cables, NEC compliant

WARNING!: The ampliﬁer AC mains power is present in the loop-thru cables. If the AC mains is connected to one LA108 or LA112 loudspeaker, electrical power is present on all connected loop-thru cables.

WARNING!: Do not connect more than six (6) LA108 or LA112 loudspeakers together using the jumper power cables (one AC mains power cord and ﬁve jumper cables). When using jumper power cables, make all loop-thru connections prior to connecting to the AC mains power source.

—Figure67—

Daisy-Chaining Procedure

1. Insert the locking POWER-OUT connector of the jumper cable (not supplied) fully into the OUTLET connector on the loudspeaker’s rear panel. Twist clockwise until it locks in place.

2. Insert the locking POWER-IN connector into the INLET connector on the rear panel of the next loudspeaker in the chain. Twist clockwise until it locks in place.

3. Repeat until all loudspeakers in the array (up to six (6), using ﬁve (5) loop-thru jumper cables) are properly connected.

Please follow the table below to safely power a speciﬁc loudspeaker array.

• 2x LS118 subwoofers with 3x LA112 loudspeakers in a ground-stack (total 11.4A/100V, 10.5A/120V or 6A/220~240V)

WARNING!: Always ensure the circuit is loaded no higher than 80% of the circuit rating when daisy-chaining AC power to multiple boxes. For example, never load more than 12 Amps on a 120 V/15 A circuit, or 8 Amps on a 230 V/10 A circuit.

Power On Sequence

1. Turn down the output levels on the mixer (or other audio source) to its minimum position.

2. Switch on all source devices (mixer, musical instruments, audio player, etc).

3. Prepare the LA108 or LA112 loudspeaker for power by twisting the locking POWER-IN connector clockwise. If the LA108 or LA112 loudspeaker are daisy-chained to other boxes, the AC POWER-IN only needs to be inserted in the ﬁrst loudspeaker of the array (usually the lower unit).

4. Connect the AC mains power cable to the AC mains outlet.

5. Verify that all power connections have been made by ensuring the blue POWER indicator LED is illuminated on every single loudspeaker in the array.

6. The output level controls on the mixer/audio source may now be brought up.

Power Off Sequence

1. Turn down the output levels on the mixer (or other audio source) to its minimum position.

2. Disconnect power from the AC mains source.

3. Disconnect the LA108 or LA112 loudspeaker power cable by pulling the connectors tab back and twisting the locking POWERIN connector counter-clockwise. If the LA108 or LA112 loudspeaker are daisy-chained to other loudspeakers/subwoofers, then power will be disconnected to the rest of the array.

4. Verify that power connections have been disconnected on each unit. When the loudspeaker/subwoofer blue POWER indicator LED, or yellow Standby LED, is no longer illuminated and the rear screen is turned off, then it is safe to proceed.

5. Power off all source devices (mixer, musical instruments, audio player, etc.).

Analog Audio Connections

NOTE: loudspeaker will default to digital audio if a Dante® audio connection is made, causing the analog audio inputs to be muted until the Dante® signal is disconnected. The analog connections can be used alongside a line array that is Ethernetconnected and QSC SysNav™ controlled, as standalone without SysNav control, or as a backup audio connection in the event of digital audio failure.

XLR Connections

Each loudspeaker features a LINE IN (input) XLR and a LINE OUT (output) XLR to support daisychaining multiple loudspeakers/subwoofers in an array.

The LINE OUT XLR connector is wired in parallel to the LINE IN XLR connector, making it a direct pass-thru. It does not output any Post-DSP signal, nor is the level on the LINE OUT affected by the digital GAIN setting adjusted on the loudspeaker.

Using the XLR connectors, you can safely daisy-chain up to six (6) loudspeakers plus two (2) subwoofers without any signal losses.

NOTE: It is not recommended to use unbalanced audio connections with LA108/LA112 loudspeakers. Always use XLR balanced audio connections and wiring as shown in Figure 69.

While both digital audio and analog audio connections can be physically connected simultaneously, the

Daisy-Chaining with Balanced XLR Jumper Cables

1. Connect the audio source (mixer, musical instruments, audio player, etc.) to the LINE IN XLR connector (6) on the rear panel.

2. If additional units are daisy-chained in the array, connect the audio loop-thru jumper cable (not supplied) from the LINE OUT XLR connector to the LINE IN XLR connector on the next loudspeaker.

3. Continue this process until all loudspeakers in the array are connected using balanced XLR cables.

Network Connections

The dual network connectors also support daisy-chaining multiple loudspeakers in an array. Unlike the powerCON and XLR connectors, which have dedicated input and throughput connectors, the network ports are identical switched-ethernet ports, which means either can be used as an input or as a network hop to the next unit in the array.

The network ports can accept either a rugged etherCON connector or a standard RJ45 connector; however, it is always recommended to use etherCON type connectors, rather than conventional RJ45 connectors, as the mechanical robustness and EMC performance is superior.

Each loudspeaker includes two IP addresses, one dedicated to “control” and one dedicated to “Dante audio-over-IP.” However, both control and Dante data trafﬁc are carried over a single CAT5/6 cable into a single RJ45 port.

Daisy-Chaining with Network Jumper Cables

There are two common methods for connecting network devices:

a. Star Topology: With the star topology method, each device has its own port on an ethernet switch. This is the most robust method,

but it requires a cable home run from each device back to the ethernet switch, which is ﬁne for permanent installations but challenging for temporary deployments.

b. Daisy Chain: The daisy-chain method requires dual switched ports on each device, as found on the LA108/LA112 loudspeakers.

While daisy-chaining is much easier to deploy, it should be noted that each “hop” incurs a latency penalty, measured in microseconds that quickly add up. Therefore, a pre-determined latency is applied to each Dante-receiving device to account for switch hops, eliminating the risk of dropped packets and resulting audio glitches.

The Dante latency settings are based on worst-case latency assumptions and are therefore quite conservative. The LA108/LA112 loudspeakers default to 1 ms, which will accommodate up to 10 switch hops.

As a reference point, a Dante mixer connected through an ethernet switch to a 6-box daisy-chained array of LA108 or LA112 loudspeakers is the equivalent of 6 switch hops.

If 5 switch hops or less are used, there is the potential to adjust the latency down from 1 ms to 0.5 ms using the Dante Controller software. Please refer to Audinate for more information on Dante Controllers.

For ethernet daisy-chaining, the optional LA-KIT-J or LA-KIT-J-NA jumper kit mentioned above is needed (refer to the Accessories section for more information).

Connecting to a Network

1. Connect the network source (router, switch, or computer) to the RJ45 jack on the rear panel using a CAT5/6 cable (not supplied).

2. If using the RJ45 loop-thru connections, connect another CAT6 cable to the available RJ45 port on the ﬁrst loudspeaker and connect the open-end connector to the RJ45 input on the next loudspeaker.

3. Continue this process until all loudspeakers in the array are connected using RJ45 digital connections.

Network Control

There are two modes of operation using network control:

a. Indirect Mode: This duplicates all the functionality of the Rear User

Interface (RUI) as described in the following section. Indirect mode allows users to connect ethernet to just one box. Low data communication to the other boxes is managed via wireless transmission (QSC AWARE™).

NOTE: Indirect mode cannot be used for Firmware updates.

b. Direct Mode: This mode offers greater functionality, but it requires ethernet connection to every box in the array. When all boxes

in the array are discovered on the network, Indirect mode is disabled. To update Firmware, an Ethernet connection must be attached to each box.

—Figure70—

An Array can be controlled and monitored using one of two software applications:

a. QSC SysNav™ (System Navigator): This Windows application is available from QSC.com and allows the user to discover, control

and monitor each loudspeaker within the array. SysNav also manages Firmware updates.

b. QSC Q-SYS Designer™: This Windows application is available from QSC.com and allows the user to discover, control, and

monitor each loudspeaker within the array.

NOTE: Q-SYS Designer requires a Q-SYS Core to fully function. More information on Q-SYS Designer is available from the online Helpﬁle https://q-syshelp.qsc.com/

Dante® Audio Setup

Each array of loudspeakers can subscribe to a Dante audio-over-IP Transmitter (TX), sent over the network from common audio sources, such as a digital mixing console or a QSC Q-SYS Core. Dante subscriptions can be set up using one of two methods:

a. QSC SysNav™ (System Navigator): This Windows application is available from QSC.com and allows the user to view all Dante

Transmitters (TX) discovered on the network and then subscribe a loudspeaker (or array of loudspeakers) to that transmitter.

b. Dante Controller: This Windows or macOS application is available from Audinate.com and provides users with more advanced

tools to manage Dante trafﬁc.

Cooling

The LA108 and LA112 models are internally powered loudspeakers that contain Class D power ampliﬁers, which produce some heat.

• Allow a minimum of 15 cm (6 inches) clearance at the rear of the enclosure for cooling.

• Do not restrict airﬂow to the rear of the loudspeaker enclosure.

Outdoor Installations

CAUTION!:

- Do not install LA108/LA112 loudspeaker enclosures with their rear panels exposed to direct sunlight. Direct sunlight will heat the ampliﬁer module and reduce its ability to produce full output. Install sunshades if the application merits. Maximum ambient temperature for full performance to speciﬁcation is 50° C (122° F).

- Do not install enclosures with exposure to rain or other water sources. The enclosure is not weatherproof. Outdoor installations must provide protection from the elements.

Home Screen Status

Utilizing infrared technology, LA108 and LA112 active line array loudspeakers can sense the state of other array member loudspeakers, as well as the state of the entire array at any given point in time. Based on the state of the array, the top bar will show the following colors to verify the array status at a glance.

Top Bar

• Green: The array is optimized, and working in its factory-recommended state for the deployment

it is currently in. If more than one box is present, grouped functions like Gain, Ar-Q™ Array Equalization, High-Pass Filter, EQ, Delay, and Input Sensitivity can all be adjusted from a single loudspeaker for the entire array.

• Orange: The Array is not optimized due to a mismatch of parameters from the loudspeakers' last

known state. Grouped functions will not operate together, and each loudspeaker must be adjusted manually via its individual user interface. In this state, the array can be optimized again by simply pressing the rotary controller for three (3) seconds, which will set the array to a factory-optimized state, returning the status to green.
