HK Audio CTA 208 Mid/High - Manual (Page 12)

ConTour Array™ 1.3
ConTour Array™ rigging hardware consists of the
following parts:
• a rigging frame with two shackles for attaching
motors or chain hoists.
• integrated rigging points on the side and back for
flying ConTour Array™ CTA 208 Mid/High units.
• three quick-release pins per CTA 208 for
connecting the enclosure to the rigging frame.
Important note on pins: Quick-release pins connect
rigging hardware and speaker enclosures, and their
proper function must be tested and verified. Pins
must always engage fully in the (fitted) hole. Under
no circumstances may these pins release on their
own when subjected to tractional forces. The nib in
the center of the pinhead must always be depressed
to insert pins; it releases the ball detents in front.
Once the pin engages in the hole, the nib must ease
back to its initial position.
1.1 Mounting the Rigging Frame
It takes two people to perform these tasks. Remove
the quick-release pins from the enclosure. Set the
rigging frame on the enclosure. First attach the two
front connectors. Turn the rigging frame‘s connector
component down and slide it into the rear
rigging connector.
Insert the rear pin through the hole labeled 0°.
Attach to the rigging frame the shackle that accepts
the motor hook. Your choice of pick point depends
on how sharply you aim to curve the array later.
Note: Depending on application, you may not be
able to select a pick point with a shackle. In this
case, use two shackles and a suitable O-ring as
shown in Figure 10.
Check all pins on the top rigging frame to ensure
they seat firmly. Attach the motor to the shackle.
Important: Ensure the motor‘s chain bag hangs
freely and does not rest on the rigging frame!
Engage the motor to lift the cabinet from the case.
Roll the case off to the side. Remove the two front
pins from the enclosure you wish to mount and fold
down its connector component. Now you can rig
further cabinets.
Tip: If you intend to rig additional enclosures, we
recommend that you attach all the required speaker
cords to the rigging frame now because this task
becomes more difficult as the array grows higher.
Be sure to use cords of sufficient length!
1.2 Setting the DualCurve™ Angle
Curve the two CTA 208 cabinets using the rear
connector component. You have two angles to
choose from, 0° and 9°. Remove the pin on the
rear, insert lead the connector into the rigging track
and secure the connector component with the pin
as pictured.
1.3 Rigging Additional
CTA 208 Mid/High Enclosures
Hoist the mounted CTA 208 Mid/High cabinets to a
height that allows you to roll a second case holding
two enclosures under the array. Remove the two
front pins from the enclosure you wish to mount.
Move the second case with two additional CTA 208s
into position. Slowly lower the top two cabinets
until the two front connectors engage. Insert the
two front pins first, ensuring they engage fully and
securely (see Figure 11 a). You may have to shift
the two enclosures slightly to ease the pins into
position. To attach the rear connector component,
you must swivel it out of the track and ensure it
faces down (see Figure 11 b). Insert the pin through
the hole labeled 0° or 9° as required.
Hoist the array consisting of four CTA 208
enclosures high enough to remove it fully from the
case. Secure the hoisted array against blasts of wind
or unintentional twisting to prevent it from moving.
