5.2 As an Independent Bass Array on a Second
Rigging Frame
The standard rigging frame is certified to fly up to ten CAD 115 subwoofers in
stacked array. Be sure to also read and heed the safety regulations in chapter C
of the manual.
Rigging
Set the standard rigging frame on the CAD 115 subwoofer with the rubber feet
facing down. Remove the four pins on the rigging frame. Attach the four (optio-
nal) connector components between the rigging frame and the CAD 115 enclosu-
re using the pins. Attach the shackles for the motor to the rigging frame. Attach
the motor to the shackle and lift the subwoofer. Now you can rig additional CAD
115 bins below this subwoofer. You need four connector components and eight
pins for each subwoofer to do this.
5.3 In Combination with CAD 208 Mid/High
Enclosures
Configuring subwoofers and mid/high enclosures together in a single array may
be practical, depending on application. Subwoofers must be rigged on top of
the flown array for this application.
Mind the rigging frame’s maximum permissible load. Before you begin, add
up the individual components’ weights to determine the total system weight.
Refer to tables 1 and 2 in chapter C, Rigging the CADIS™ System, for weight
specifications.
Use the connector to attach the top CAD 115 Sub to the rigging frame. To add
mid-/high-range enclosures to the array, mount the optional rigging yoke to the
bottom subwoofer by inserting four pins into the enclosure’s recessed rigging
rails.
You may mount the first mid/high enclosure to the rigging yoke in fixed or in
compression mode. For a 0° set angle, insert the first pin through the slot
labeled Link on the enclosure and attach the connector component by inserting
the second pin in the hole labeled 0° Ground-stacking.
This configuration is recommended for smaller venues, for example, in which
enclosures cannot be flown, or when you want to aim the array to cover galle-
ries, terraces or balconies.
5.4 With a Standard Rigging Frame
Set the standard rigging frame, without shackles and with the rubber feet facing
down, on the ground, on bass bins (attaching the frame to the bin) or on the
stage so that the connector components for the CAD 208 enclosures face up.
Fig. 23: Ground stack with the standard rigging frame
Remove all pins from the rigging frame and mount the CAD 208 enclosures
upside down, one after another. The procedure is the same as for a flown sy-
stem in fixed mode, except that enclosures are stacked upside down. This lets
you tilt the stack downwards by up to 7.5°. To do this, use the set angles in fixed
mode. The table below shows which angle between the rigging frame and the
first mid/high enclosure gives you the desired down-tilt:
Desired down-tilt Label on the CAD 208
0° (horizontal) 7.5°
1.5° 6°
3° 4.5°
4.5° 3°
6° 1.5°
7.5° 0°

Caution: Always secure ground stacks with a suitable lashing strap to prevent
slippage!
