Introduction
Introduction
Kara II long throw line source
Part of the K Series, Kara II is a modular line source system that can be deployed standalone or with its companion subwoofer SB18. Assembled as a variable curvature line source with class-leading SPL per weight and footprint, Kara II is ideal for applications that require clarity and long throw capability such as performing arts, congregations, large corporate, or special events. Based on the Kara design, Kara II adds exibility with PanexTM. A single Kara II enclosure offers four horizontal directivity patterns: 70� or 110� symmetrical and 90� asymmetrical on either side. With a tighter control of the directivity, the 70� setting brings an additional 2 dB compared to the 110� setting increasing throw capability. With Panex and inter-element angles ranging from 0� to 10�, a Kara II line source coverage can be precisely tailored to any audience geometry. On its own Kara II can be used as a main system for vocal reinforcement and music material with light LF requirements or as a complement to large sound systems in ll and delay applications. Associated with its companion subwoofer SB18, Kara II modular system can accommodate any program material requiring bandwidth, contour and output.

Assessing mechanical safety
Mechanical safety of the rigging system Before any installation, always model the system in Soundvision and check the Mechanical Data section for any stress warning or stability warning.
In order to assess the actual safety of any array conguration before implementation, refer to the following warnings:
Rated working load limit (WLL) is not enough The rated WLL is an indication of the element resistance to tensile stress. For complex mechanical systems such as loudspeaker arrays, WLLs cannot be used per se to determine the maximum number of enclosures within an array or to assess the safety of a specic array conguration.
Maximum pullback angle If a pullback accessory is available, the pullback angle must not exceed a 90� negative site angle.
Mechanical modeling with Soundvision The working load applied to each linking point, along with the corresponding safety factor, will depend on numerous variables linked to the composition of the array (type and number of enclosures, splay angles) and the implementation of the ying or stacking structure (number and location of ying points, site angle). This cannot be determined without the complex mechanical modeling and calculation offered by Soundvision.
Assessing the safety with Soundvision The overall safety factor of a specic mechanical conguration always corresponds to the lowest safety factor among all the linking points. Always model the system conguration with the Soundvision software and check the Mechanical Data section to identify the weakest link and its corresponding working load. By default, a stress warning will appear when the mechanical safety goes beyond the recommended safety level.
Safety of ground-stacked arrays in Soundvision For ground-stacked arrays, a distinct stability warning is implemented in Soundvision. It indicates a tipping hazard when the array is not secured to the ground, stage or platform. It is the user's responsibility to secure the array and to ignore the warning.
Additional safety for own arrays When ying an array, use available holes to implement a secondary safety.
Considerations must be given to unusual conditions Soundvision calculations are based on usual environmental conditions. A higher safety factor is recommended with factors such as extreme high or low temperatures, strong wind, prolonged exposition to salt water, etc. Always consult a rigging specialist to adopt safety practices adapted to such a situation.

Avoid using Kara and Kara II in the same line source The acoustic coupling between Kara and Kara II is not optimal.
Line source
Deployed as a standalone line source, a Kara II system operates over the nominal bandwidth of the Kara II enclosure, with an adjustable horizontal directivity. The [KARA II 70], [KARA II 90], and [KARA II 110] presets deliver a reference frequency response in long throw applications. Each preset is dedicated to a horizontal directivity setting (see Adjustable ns (p.13)). The Kara II enclosure is driven by the LA4X / LA8 / LA12X amplied controllers.

This feature is available on: LA4X LA12X
ENCLOSURE CHECK measures impedance at the reference frequencies for the connected loudspeaker family. The measured impedance is compared to the expected range allowing for fast detection of loudspeakers presenting circuit continuity issues.
The results can be used for preliminary diagnosis but cannot replace a comprehensive quality control.
Prerequisite
ENCLOSURE CHECK measurements can only be reliable if the following requirements are met:
Environment and temperature: � Ambient temperature must be comprised between 0 �C / 32 �F and 40 �C / 104 �F. Ideal temperature is 20 �C / 68 �F. � Enclosures must be at room temperature. If warm from a recent high level use or recently moved from a cold environment, let the loudspeakers reach room temperature before starting.
Enclosures: � Enclosures must be included in the embedded factory preset library. � Enclosures must be in nominal operating conditions: � Remove covers or dollies obstructing the loudspeakers or the vents. � Check for obvious physical damage or air leak: visually inspect the grill, gasket, cabinet, and connector plate for loose, missing or damaged parts.
Connection: � Use only 10 m / 30 ft 4 mm� / AWG 11 speaker cables. � Do not connect enclosures in parallel.
Amplied controllers: � LA4X must run at least rmware version 1.1.0. � LA4X load sensors must be calibrated. Refer to the Load Sensor Calibration Tool technical bulletin for more information. � LA4X must warm up for at least 10 minutes after power up. Do not power off, reboot or switch to standby mode to avoid resetting the countdown. � Load a preset corresponding to the connected loudspeaker's family. Presets from the user memories may be used on condition they are made of presets supported in the embedded factory preset library.
Procedure
1. Power up the amplied controller. Let LA4X warm up for at least 10 minutes. 2. Connect the loudspeaker enclosures to the amplied controller. 3. Load a preset from or built from the embedded library corresponding to the connected loudspeaker family. 4. On the amplied controller, use the encoder wheel to select MONITORING & INFO.

Flying a Kara II standalone array
Using M-BUMP
Modeling and safety
Any system must be modeled before installation so as to ensure acoustical and mechanical conformity. This can be done using L-Acoustics Soundvision Software which will assist the user to:
� Determine the number of required Kara II enclosures. � Calculate the M-BUMP site angle and the inter-enclosure angles. � Check the mechanical conformity of the system.
The M-BUMP can nominally y an array of up to 24 Kara II along with all loudspeakers cables (refer to Mechanical safety (p.31)). However, this maximum number can decrease in line with the array curvature. Always refer to the mechanical data and warning indications provided in Soundvision Software (Mechanical Data section) to verify the mechanical conformity of the system before installation. The Kara II and M-BUMP fully integrated rigging systems allow assembling the array with no need for any external accessory. The following rst procedure describes how to y a vertical Kara II array under an M-BUMP. It is recommended to rig the Kara II by successively adding arrays of 3 enclosures (called ARRAY#1, ARRAY#2... in the order of appearance in the procedure). The second procedure describes how to disassemble the array.
Array mounting
About this task
All along the procedure: Strictly follow the sequence of the successive steps. Systematically verify that each BLP is fully inserted. Systematically verify that the bolt is fully screwed in on each shackle. For clarity purposes the loudspeaker cabling procedure will not be described. The loudspeaker cables will not be represented on the gures. Use a strain relief to avoid mechanical stress at the connector locations due to cable weight. The motor hooks or stingers will not be represented on the gures.
Procedure
1. Place an M-BUMP at the rigging location. Turn it so that the text of the identication plate is readable and the laser slits are directed towards the audience.

Kara II owner's manual (EN) version 3.1

Rigging procedures
2. (Optional, see M-BUMP rigging options (p.194)) Install one or two M-BAR on the M-BUMP as follows (repeat for each M-BAR): a) Remove both T-BLP from the M-BAR. b) Insert both M-BAR studs face to the desired M-BUMP holes. c) Secure by inserting both preceding T-BLP through M-BAR studs and M-BUMP holes. b.
c.
3. Attach the shackle(s) to the M-BUMP according to the desired conguration (see M-BUMP rigging options (p.194)). 4. Place a full ight-case at the rigging location and remove the lid. Direct the front face of the 3-Kara II array towards
the audience. In the following, the array will be designated as ARRAY#1 and the enclosures as KARA#1 to KARA#3 from top to bottom. 5. Check the inter-enclosure connections in ARRAY#1 (repeat for each side): a) For both front rigging points, verify that the front arm is open and locked to 2 Kara II by 2 R-BLP inserted in
yellow link holes. b) For both rear rigging points, verify that the angle arm cursor is aligned with the 0� angle value and locked to
2 Kara II by 2 R-BLP, the upper one inserted in a yellow link hole and the bottom one inserted into angle hole 0�/2�/4�.
Risk of blocked ball-locking pin. Be careful not to trap the ball-locking pin tether between the rigging arm and the side handle.

Kara II owner's manual (EN) version 3.1

Rigging procedures

6. On KARA#1, take the 4 arms out as follows (repeat for each side):
a) Remove the front top R-BLP from storage position, rotate the front arm up, slide it down, and secure by reinserting the R-BLP into the yellow link hole.
b) Remove the rear top R-BLP, slide the angle arm so as to align the cursor with the 5� angle value, and secure by reinserting the R-BLP into the corresponding angle hole (1�/3�/5�/7.5�/10�).
It is recommended to select the 5� angle on the Kara II intended to be linked to the M-BUMP.
By doing this, the KARA#1 axis is parallel to the M-BUMP, so that a laser secured on M-BUMP can give the site angle of the KARA#1 enclosure.

Kara II owner's manual (EN) version 3.1

Rigging procedures
7. Remove the 4 R-BLP from the M-BUMP, put the M-BUMP on ARRAY#1 by aligning the four rigging points, and secure by re-inserting the 4 R-BLP.
8. Place ARRAY#1 beneath the rigging points, attach the motor hook(s) or stinger(s) to the shackle(s), raise the array to a height for which the angle arms of ARRAY#1 are within comfortable reach, and remove the ight-case from the rigging location.
9. With 2 people working simultaneously on each side of ARRAY#1, set the inter-enclosure angles as follows: a) While grabbing the back handle of KARA#3, remove the rear top R-BLP from KARA#2. b) Rotate KARA#2 so as to align the cursor of the angle arm with the desired angle value. c) Secure by re-inserting the R-BLP into the corresponding angle hole (0�/2�/4� or 1�/3�/5�/7.5�/10�). d) Repeat the procedure for KARA#3.

10. Place another full ight-case at the rigging location and remove the lid. Direct the front face of the 3-Kara II array towards the audience. In the following, the array will be designated as ARRAY#2 and the enclosures as KARA#4 to KARA#6 from top to bottom.

Kara II owner's manual (EN) version 3.1

Rigging procedures
11. Check the inter-enclosure connections in ARRAY#2 by applying step 5 (p.55).

12. On KARA#4, take both front arms out as follows (repeat for each one): remove the front top R-BLP, rotate the front arm up, and slide it down. Do not re-insert the R-BLP.
13. Raise ARRAY#1 slightly higher than the front arms of ARRAY#2 and place ARRAY#2 beneath ARRAY#1.
14. Connect both front rigging points between ARRAY#1 and ARRAY#2 as follows:
a) Slide both KARA#4 front arms up and align them with the KARA#3 front bottom rigging points. b) On KARA#3, remove both front bottom R-BLP from the storage holes and re-insert them into the bottom yellow link
holes to secure the front arms to KARA#3. c) Lower the array until the front corners of KARA#3 and 4 are in contact (front arms kept vertical). d) Secure the front arms on KARA#4 by inserting both top R-BLP into the top yellow link holes.

15. Raise the array to a height for which the angle arms of ARRAY#2 are within comfortable reach and remove the ightcase from the rigging location.
16. With 2 people working simultaneously on each side of the array, connect both rear rigging points between ARRAY#1 and ARRAY#2 as follows:

Using KARA-MINIBU
Modeling and safety
Any loudspeaker assembly must be modeled before installation so as to ensure acoustical and mechanical conformity. This can be done using L-Acoustics Soundvision Software which will assist the user to:
� Determine the number of required Kara II enclosures. � Calculate the KARA-MINIBU site angle and the inter-enclosure angles. � Check the mechanical conformity of the loudspeaker assembly.
The KARA-MINIBU can nominally y an array of up to 6 Kara II along with all loudspeaker cables (refer to Mechanical safety (p.31)). However, this maximum number can decrease in line with the array curvature. Always refer to the mechanical data and warning indications provided in Soundvision Software (Mechanical Data section) to verify the mechanical conformity of the loudspeaker assembly before installation. The Kara II and KARA-MINIBU fully integrated rigging systems allow assembling the array with no need for any external accessory. The following rst procedure describes how to y a vertical Kara II array under a KARA-MINIBU. It is recommended to assemble the Kara II by successively adding arrays of 3 enclosures (called ARRAY#1 and ARRAY#2 in the order of appearance in the procedure). The second procedure describes how to disassemble the array.
Array mounting
About this task
All along the procedure: Strictly follow the sequence of the successive steps. Systematically verify that each BLP is fully inserted. Systematically verify that the bolt is fully screwed in on each shackle. For clarity purposes the loudspeaker cabling procedure will not be described. The loudspeaker cables will not be represented on the gures. Use a strain relief to avoid mechanical stress at the connector locations due to cable weight. The motor hooks or stingers will not be represented on the gures.
Procedure
1. Bring a full Kara II ight-case to the rigging location and remove the lid. Direct the front face of the Kara II array towards the audience. In the following, the array will be designated as ARRAY#1 and the enclosures as KARA#1 to KARA#3 from top to bottom.

Flying an SB18/Kara II mixed array or an SB18 standalone array
Using M-BUMP
Modeling and safety
Any system must be modeled before installation so as to ensure acoustical and mechanical conformity. This can be done using L-Acoustics Soundvision Software which will assist the user to:
� Determine the number of required Kara II enclosures. � Calculate the array site angle and the inter-enclosure angles. � Check the mechanical conformity of the system.
The M-BUMP can nominally y an array of up to 4 SB18/12 Kara II or 16 SB18 along with all loudspeakers cables (refer to Mechanical safety (p.31)). However, this maximum number can decrease in line with the array curvature and/or the acoustic coupling conditions (depending on the selected operation mode as described in the Kara II User manual). ALWAYS refer to the mechanical data and warning indications provided in Soundvision Software (Mechanical Data section) to verify the mechanical conformity of the system before installation. The Kara II, SB18 and M-BUMP fully integrated rigging systems allow assembling the array with no need for any external accessory. The following rst procedure describes how to y a vertical SB18/Kara II array using two M-BUMP. According to the array composition, the SB18 enclosures can be rigged one by one or by pairs (as shown in the procedure). It is recommended to rig the Kara II by successively adding arrays of 3 enclosures (called ARRAY#1, ARRAY#2... in the order of appearance in the procedure). The second procedure describes how to disassemble the array.

Using KARA-MINIBU
Modeling and safety
Any loudspeaker assembly must be modeled before installation so as to ensure acoustical and mechanical conformity. This can be done using L-Acoustics Soundvision Software which will assist the user to:
� Determine the number of required Kara II enclosures (acoustic data not available for subwoofers). � Calculate the array site angle and the inter-enclosure angles. � Check the mechanical conformity of the loudspeaker assembly.
The KARA-MINIBU/KARA-MINIBUEX structure can nominally y an array of up to 2 SB18/6 Kara II or 4 SB18 along with all loudspeakers cables (refer to Mechanical safety (p.31)). However, this maximum number can decrease in line with the array curvature. Always refer to the mechanical data and warning indications provided in Soundvision Software (Mechanical Data section) to verify the mechanical conformity of the loudspeaker assembly before installation.
The Kara II, SB18, KARA-MINIBU, and KARA-MINIBUEX fully integrated rigging systems allow assembling the array with no need for any external accessory.
The following rst procedure describes how to y a vertical SB18/Kara II array using two KARA-MINIBU/KARAMINIBUEX rigging structures. It is recommended to assemble the Kara II by successively adding arrays of 3 enclosures (called ARRAY#1 and ARRAY#2 in the order of appearance in the procedure). The second procedure describes how to disassemble the array.
Array mounting
About this task
All along the procedure: Strictly follow the sequence of the successive steps. Systematically verify that each BLP is fully inserted. Systematically verify that the bolt is fully driven on each shackle. Systematically verify that each bolt is fully driven on the KARA-MINIBUEX.
For clarity purposes the loudspeaker cabling procedure will not be described. The loudspeaker cables will not be represented on the gures. Use a strain relief to avoid mechanical stress at the connector locations due to cable weight. The motor hooks or stingers will not be represented on the gures.

Stacking a Kara II standalone array
Using M-BUMP
Modeling and safety
A Kara II array can be stacked onto an M-BUMP/M-BAR/M-JACK platform (platform stacked array). The platform provides tilt adjustments in case of slope surface and increases the array stability. Any platform stacked array must be modeled before installation so as to ensure acoustical conformity. This can be done using L-Acoustics Soundvision Software which will assist the user to:
� Determine the number of required Kara II enclosures. � Calculate the inter-enclosure angles.
A platform stacked array can be composed of a maximum of 9 Kara II enclosures along with all loudspeakers cables (refer to Mechanical safety (p.31)). The platform must be installed in rear extension conguration if the Kara II array is intended to have a positive site angle (refer to Stacking platform conguration (p.200)). The platform must be installed in front extension conguration if the Kara II array is intended to have a negative site angle (refer to Stacking platform conguration (p.200)) and a at shape (all inter-enclosure angles are close to 0�). The Kara II and M-BUMP fully integrated rigging systems allow assembling the array with no need for any external accessory. The following rst procedure describes how to mount a vertical Kara II platform stacked array. The second procedure describes how to disassemble the array.

Stacking an SB18/Kara II mixed array or an SB18 standalone array

Using M-BUMP

Modeling and safety

An SB18/Kara II mixed array or an SB18 standalone array can be stacked directly on the ground (ground stacked array) or onto an M-BUMP/M-BAR/M-JACK platform (platform stacked array). The gure below shows a mixed array of each type and gives the associated conditions of use.

Ground stacked array

Platform stacked array

� To be stacked on a perfectly horizontal and regular surface ONLY

� Provides tilt adjustments in case of slope surface � Increases Kara II array site angle range

Ground stacked arrays
A ground stacked array requires to be installed on a perfectly horizontal and regular surface. A maximum of 4 SB18 can be ground-stacked (refer to Mechanical safety (p.31)). Refer to the Soundvision model to assess the mechanical safety of a ground-stacked SB18/Kara II mixed array.
SB18/Kara II mixed array mounting procedure: Put the bottom SB18 on the ground (front grill logo upside) and apply the Array mounting (p.123) procedure WITHOUT using the M-BUMP/M-BAR/M-JACK platform.

Kara II owner's manual (EN) version 3.1

121

Rigging procedures
SB18 standalone array mounting procedure: Put a rst SB18 on the ground with feet (and front grill logo) downside. Put a second SB18 onto the rst one and link both enclosures by applying step 4.c (p.75). Repeat the procedure until all SB18 composing the array are rigged. While installing follow the step 8 (p.77) indication.
Platform stacked arrays
Any SB18/Kara II platform stacked array must be modeled before installation so as to ensure acoustical and mechanical conformity. This can be done using L-Acoustics Soundvision Software which will assist the user to:
� Determine the number of required Kara II enclosures. � Calculate the inter-enclosure angles.
A maximum of 4 SB18 can be platform-stacked. Refer to the Soundvision model to assess the mechanical safety of a platform-stacked SB18/Kara II mixed array. The platform must be installed in rear extension conguration if a Kara II array is intended to be rigged with a positive site angle (refer to Stacking platform conguration (p.200)). The platform must be installed in front extension conguration if a Kara II array is intended to be rigged with a negative site angle (refer to Stacking platform conguration (p.200)) and a straight shape (all inter-enclosure angles are close to 0�).
The Kara II, SB18, and M-BUMP fully integrated rigging systems allow assembling the array with no need for any external accessory. The following rst procedure describes how to mount a vertical SB18/Kara II or SB18 platform stacked array. The second procedure describes how to disassemble the array.

Flown array options and site angle setting
Using M-BUMP
M-BUMP rigging options
L-Acoustics recommends 5 different rigging options to y the M-BUMP for arrays containing Kara II and/or SB18 enclosures. It is possible to use 0, 1, or 2 M-BAR and 1 or 2 rigging points (see gure below).
Always refer to the mechanical data and warning indications provided in Soundvision Software (Mechanical Data section) to verify the mechanical conformity of the loudspeaker system before installation.
Option 1: 0 M-BAR, 1 point 1 motor 3 positions (front, center, rear)
Option 2: 0 M-BAR, 2 points 2 motors Fixed front and rear positions (spacing = 400 mm/15 inch)
Option 3: 1 M-BAR, 1 point 1 motor Variable position (see M-BUMP site angle setting (p.195)) Left view = rear extension conguration Right view = front extension conguration Option 4: 1 M-BAR, 2 points 2 motors Fixed front and rear positions (spacing = 900 mm/35 inch) Left view = rear extension conguration Right view = front extension conguration Option 5: 2 M-BAR, 2 points 2 motors Variable position from front to rear Same hole number for both points [8.2.2] (spacing = 663 mm/26 inch) Left view = rear extension conguration Right view = front extension conguration

194

Kara II owner's manual (EN) version 3.1

Flown array options and site angle setting
M-BUMP site angle setting
The M-BUMP site angle setting will be discrete or continuous depending on the chosen rigging option. Rigging option 1 offers three discrete angle values. Rigging options 3 and 5 offer 34 discrete angle values. First select the M-BAR position (A or B) and then the shackle position (holes 0-16) as shown in the gures below.
For rigging options 1, 3, and 5 the M-BUMP site angle will also depend on the size and shape of the array (number of enclosures and inter-enclosure angles). Refer to Soundvision Software for site angle calculation.
Discrete angle selection (rear extension conguration)

Discrete angle selection (front extension conguration)

Rigging options 2 and 4 allow continuous M-BUMP site angle setting depending on the relative heights between the front and rear rigging points. Option 2 offers a small setting range. Option 4 enlarges the setting range for negative site angles in rear extension conguration and positive site angles in front extension conguration (see gure below).
For option 4, it is recommended to position both shackles in holes 0 and 16.

Flown array options and site angle setting
KARA-MINIBU site angle setting
The KARA-MINIBU site angle setting will be discrete or continuous depending on the chosen rigging option. Rigging options 1 and 3 offer 17 discrete site angle values in each conguration by selecting the single shackle position (holes 1-17). The hole numbering convention is shown in the gures below.
For rigging options 1 and 3 the KARA-MINIBU site angle will also depend on the size and shape of the array (number of enclosures and inter-enclosure angles). Refer to Soundvision Software for site angle calculation. Hole 15 allows setting the site angle of an SB18 standalone array to 0�. Rigging hole numbering convention for KARA-MINIBU

Recommendation for speaker cables

Follow the recommended maximum length for loudspeaker cables to ensure minimal SPL attenuation.
Cable quality and resistance Only use high-quality fully insulated speaker cables made of stranded copper wire. Use cables with a gauge offering low resistance per unit length and keep the cables as short as possible.
The table below provides the recommended maximum length for loudspeaker cables depending on the cable gauge and on the impedance load connected to the amplier.
