Page 8: 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.

Page 20: Rigging System Description
Kara II features a four-point rigging system composed of two adjustable rigging arms secured with R-BLP (round- shaped ball-locking pins) and two lodgings with R-BLP on both sides of the enclosure. Kara II can be connected to other Kara II enclosures or to dedicated rigging accessories. The inter-enclosure angle can be set between 0° and 10°.

Page 23: Rigging Elements
M-BUMP Rigging structure The M-BUMP rigging structure has been designed to fly or stack the Kara II enclosures as a variable-curvature, vertical line source array. M-BUMP also allows Kara II to be rigged to an SB18 subwoofer array. M-BUMP also can fly straight vertical SB18 arrays.
Page 24: Kara-Minibu
KARA-MINIBU Rigging structure KARA-MINIBU rigging structure has been designed to fly or stack the Kara II enclosures as a variable-curvature, vertical line source array. KARA-MINIBU also allows Kara II to be attached to an SB18 subwoofer array. KARA-MINIBU also can fly straight vertical SB18 arrays.
Page 25: M-Bar
The M-BAR extension bar is a complementary rigging element for M-BUMP. Optionally used as a single element or in pair in flown configurations, it will extend the site angle capability of Kara II and SB18 arrays. In stacked configurations, its use is required in pairs as part of the stacking platform (see M-JACK, KARA-ANGARMEX (p.26)).
Page 26: M-Jack, Kara-Angarmex
M-JACK consists in four feet to be used along with one M-BUMP and two M-BAR in order to form a stacking platform for a variable-curvature, vertical Kara II line source array. KARA-ANGARMEX are two angle arm extensions providing extra 10° downwards site angle for the bottom Kara II in stacked configurations.

Page 29: Kara-Pullback
Rigging system description KARA-PULLBACK KARA-PULLBACK rigging accessory is used to set a Kara II array in a pullback configuration. It connects to the bottom enclosure of the array and to the hook or stinger of an additional motor. The KARA-PULLBACK is a plate on which is fixed one shackle fitted with 19 mm/0.75 inch-diameter axis.
Page 30: Transportation
Transportation Flight-case It is recommended to use a flight-case designed to ship a 3-Kara II vertical array. It should contain foam inserts to prevent array movement and the tray should be fitted with 2 wedges to keep the array vertical.
Page 31: Mechanical Safety
Mechanical safety Flown configurations The Kara II rigging system complies with 2006/42/EC: Machinery Directive. It has been designed following the guidelines of BGV-C1. 2006/42/EC: Machinery Directive specifies a safety factor of 4 against the rupture. The flown deployments described in this manual achieve a safety factor of 4 or more.
Page 32: Assessing Mechanical Safety
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.

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.

• Check the mechanical conformity of the system. The M-BUMP can nominally fly 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.
Page 57 II#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 two Kara II by two R-BLP inserted in yellow link holes.
Page 58 For both rear rigging points, verify that the angle arm cursor is aligned with the 0° angle value and locked to two Kara II by two R-BLP, the upper one inserted in a yellow link hole and the bottom one inserted into angle hole 0°/2°/4°.
Page 59 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 II#1 axis is parallel to the M-BUMP, so that a laser secured on M-BUMP can give the site angle of the Kara II#1 enclosure.
Page 60 11. Check the inter-enclosure connections in ARRAY#2 by applying step (p.57). 12. On Kara II#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 insert back the R-BLP.
Page 61 ARRAY#1 and ARRAY#2 as follows: a) Remove the Kara II#4 rear top R-BLP from its storage position, slide the angle arm so as to align the cursor with the desired angle value, and secure by inserting the R-BLP into the corresponding angle hole (0°/2°/4° or 1°/3°/5°/7.5°/10°).
Page 62 KARA-PULLBACK studs into the Kara II rigging points (long studs at the back), remove the 4 bottom R-BLP from the Kara II and secure by inserting them into the bottom yellow link holes. Attach the hook or stinger of an additional motor to the KARA-PULLBACK shackle.

Page 67: Using Kara-Minibu
Procedure 1. Bring a full Kara II flight-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 II#1 to Kara II#3 from top to bottom.
Page 68 A link hole is indicated by a yellow circle. b) Verify that each angle arm (x2) has the cursor aligned with the 0° angle label and is secured to two Kara II by two R-BLP, the top one being inserted into the link hole and the bottom one into angle hole 0°/2°/4°.
Page 69 (towards audience). c) While keeping this orientation, align the four link points of KARA-MINIBU with the four arms of Kara II#1 and secure each pair together by inserting the four R-BLP back into the same holes (insert both rear R-BLP first).
Page 70 Repeat the procedure for Kara II#3. 9. Bring another full Kara II flight-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#2 and the enclosures as Kara II#4 to Kara II#6 from top to bottom.
Page 71 ARRAY#2 as follows: a) Remove the Kara II#4 rear top R-BLP from its storage hole, slide the angle arm so as to align the cursor with the chosen angle label, and lock it in place by inserting the R-BLP into the corresponding angle hole (0°/2°/4°...
Page 72 16. Set the inter-enclosure angles in ARRAY#2 by applying step (p.70). 17. If the array is intended to be flown in pullback configuration, attach a KARA-PULLBACK to the bottom Kara II as follows: a) Align the KARA-PULLBACK studs with the Kara II link points (long studs at the back).
Page 73 Rotate ARRAY#2 downwards and position the rear corners into the tray while still suspended from the front link points. c) Remove the Kara II#4 rear top R-BLP from its angle hole, slide the angle arm so as to align the cursor with the storage label, and insert the R-BLP back into its storage hole.
Page 74 Slightly raise ARRAY#1 so that it is no longer in contact with ARRAY#2. c) Remove both Kara II#3 front bottom R-BLP from their link holes and insert them back into their storage holes. d) Rotate both Kara II#4 front arms down and insert both front top R-BLP back into their storage holes.
Page 75 Remove the four R-BLP from the KARA-MINIBU. c) Remove the KARA-MINIBU from Kara II#1 and insert the four R-BLP back into the same holes. 15. Close the four Kara II#1 arms as follows (repeat on both sides of the enclosure): a) Remove the front top R-BLP from its link hole, slide the front arm up, rotate it down, and lock it in place by inserting the R-BLP back into its storage hole.
