3. Intended Use
The K&F SPECTRA 212 rigging system is intended for exclusive use in the following:
1) Creating and suspending a horizontal array of up to six K&F SPECTRA 212 speakers
2) Creating and suspending a vertical array of up to four K&F SPECTRA 212 speakers
People may safely stand below the suspended structure during operation. The configuration
is designed for indoor use (trade shows, venues, etc.). Outdoor use is allowable if wind
pressures are horizontally dissipated at the top and bottom ends and the structure can be
taken down at wind forces of 8 bft or more. Be sure to use only genuine KLING & FREITAG
components. All parts must be secured against unwanted loosening.
4. Safety Instructions
Warning
The information described here does not relieve the user of the duty to follow the given
safety requirements and legal regulations.
Only technicians qualified as “riggers” are permitted to perform the installation steps. Be
sure to use personal protective equipment at all times.
The technicians responsible for installing the system on site are responsible for and
guarantee safe setup and use.
To prevent injury and damage, be sure to securely place or suspend arrays as specified in the
DGUV regulations 17 (BGV C1) or similar locally applicable accident-control standards.
Unless otherwise stated, use only KLING & FREITAG original parts for mounting the speakers.
Never use other parts (in particular, parts not made by KLING & FREITAG).
In mobile and stationary installations, always use installation parts supplied by KLING &
FREITAG.
Be sure to always visually inspect all components before use. In fixed installations, regularly
check all array components for signs of wear. Visual inspection includes checking all speaker-
system and flying components, supporting components (e.g. trusses, ceiling structures, etc.),
and all screwed connections. During the inspection, check all flying-system components
carefully for deformation, cracks, bolt damage, and corrosion. Remember checking the
ball-lock pin and pin bolts for proper functioning. Also check slings and lifts (e.g. shackles,
chains, and steel ropes) carefully for wear and deformation. If there are signs of wear,
cracks, or deformation, etc., replace the affected parts immediately. See also the “Care and
Maintenance” chapter on page 39.
Outdoor use is allowable if wind pressures are horizontally dissipated at the top and bottom
ends and the structure can be taken down at wind forces of 8 bft or more.
All connections must be secured against unwanted loosening.

4.1 Safety Instructions for Flying Configurations
Warning
Loudspeakers falling down impose a deadly risk for people standing near-by!
Never use the array if you have any doubt regarding its safety and reliability!
Only event technicians qualified as “riggers” are permitted to suspend a SPECTRA 212 system.
Never suspend the speakers without appropriate flying accessories.
Maximum-load specifications refer to configurations including cabling and any fittings.
Always observe the allowed configurations for the various flying scenarios.
Ensure that all connections are secured against coming loose and that only authorized,
statically tested and correctly sized supports, mounting equipment, wire ropes and chains
are used. Follow the relevant specified safety factors. Be sure to follow the relevant national
specifications, norms, and safety regulations.
Note that every suspension point as well as the supporting structure of the building (i.e.
ceiling points, cross beams and stage or PA tower, etc.) must be capable of carrying the total
load of the system (including cabling and additional fittings).
Note that the suspension points on the hall ceiling (i.e. shackles, attachment points, or chain
hoists) must comply with the DGUV regulations 17 (BGV C1) or similar locally applicable
accident-control standards. The maximum load must have been certified by an authorized
expert. When in doubt, request a confirmation by local authorities.
Also follow the operating and safety instructions supplied with the product you intend to
suspend the flying parts from (e.g. a truss). Never mount the flying parts to a product if there
is no information on safe use and maximum load.
Even with two-fall suspension, each chain and motor must be capable of carrying the entire
array mass! Make sure that the motor chains hang down vertically and are not twisted, and
that the motors are located at the required positions.
During setup, installation, and dismounting, when using chain hoists that do not comply with
the DGUV regulations 17 (BGV C1) or similar locally applicable accident-control standards,
make sure no persons stand in the danger zone below or near the speaker system.
When using a BGV C1 motor, the SPECTRA 212 system is intrinsically safe, so no secondary
safety components are required in operation;
Never use signal cables or power cords for suspending, aligning, or securing the systems. Run
the cables in a way that nobody can trip over them.
Ensure there is sufficient clear space for assembling and suspending the array on-site.
Note that arrays being lifted may swing out.
Permit only personnel directly involved with assembly or disassembly to access the working
area. The person in charge must announce all flying-part lifting and lowering activities
beforehand and make sure all people attending are aware. In this case, all persons present
must leave the swing and lifting range immediately.
Never use the flying parts for lifting or safeguarding persons or objects other than the above
speakers.

4.2 Wind loads
In case of outdoor use, stay informed of the latest wind and weather conditions. See the
following table for provisional guidance.
bft m/s Wind force Impact
0 0–0.2 Calm Smoke rises vertically.
1 0.3–1.5 Light air Direction shown by smoke drift but
not by wind vanes.
2 1.6–3.3 Light breeze Wind felt on face; leaves rustle;
wind vane moved by wind.
3 3.4–5.4 Gentle breeze Leaves and small twigs in constant
motion; light flags extended.
4 5.5–7.9 Moderate breeze Raises dust and loose paper; small
branches moved.
5 8.0–10.7 Fresh breeze Small trees in leaf begin to sway;
crested wavelets form on inland
waters.
6 10.8–13.8 Strong breeze Large branches in motion;
whistling heard in telegraph wires.
7 13.9–17.1 High wind Whole trees in motion;
inconvenience felt when walking
against the wind.
8 17.2–20.7 Gale Twigs break off trees.
Warning
Outdoor use is allowable if wind pressures are horizontally dissipated at the top and bottom
ends and the structure can be taken down at wind forces of 8 bft or more.
For outdoor uses, we recommend using at least a BGV D8+ hoisting device to prevent the
secondary safety device from loosening in the wind.
When wind speeds exceed 5 bft, be sure to constantly monitor the wind speeds and consider
possible wind effects on flying speakers. Also remember that wind speeds increase with
height.
If wind speeds might exceed 5 bft, be sure to choose rigging and securing so that they are
able to absorb at least twice the static load.
We recommend not using arrays at wind speeds exceeding 6 bft (14 m/s).
With wind speeds equaling or exceeding 6 bft, be sure to immediately clear the area below
the speakers. Use roping or lateral spanning to effectively prevent motion build-up of flying
speakers. Failing to do so may result in the emergence of large inertial forces leading to the
tower collapsing or tipping over.
At wind speeds equaling or exceeding 8 bft, be sure to get down and uninstall flying
speakers.

6. Mounting and Suspending
6.1 Mounting Horizontal Arrays
With almost all horizontal K&F SPECTRA 212 arrays, speakers are connected at their tops only.
An exception are horizontal arrays with six K&F SPECTRA 212 speakers.
Warning
Failing to attach all required connecting elements may result in a severe accident.
With an array with six K&F SPECTRA 212 speakers, be sure to always mount and secure an
extra K&F SPECTRA 212 Connector at the bottom center (i.e. between speakers 3 and 4).
6.1.1 Horizontal arrays with up to five speakers
A) B)
With horizontal arrays, you need K&F SPECTRA 212 Flybar Connector horizontal (A) and K&F
SPECTRA 212 Connectors (B) as per the number of speakers installed. Refer to the Flying
Speakers Material Lists chapter (page 34) for accessories required for the various array
types.
The procedures for mounting the K&F SPECTRA 212 Connector and the K&F SPECTRA 212
Flybar Connectors are the same.

6.1.2 Horizontal Arrays With Six Speakers
To prevent a horizontal array with six K&F SPECTRA 212 speakers from spreading when
pulling up, you need to connect the two middle speakers to each other both at the top
and the bottom using a K&F SPECTRA 212 Connector. To prevent the rigging system from
overloading, perform the necessary steps on the floor at the start of the installation process
as explained below. We recommend using two K&F SPECTRA 212 transport covers that
include the optional K&F SPECTRA 212 rigging aid set.

User's Manual K&F SPECTRA 212 Rigging System
KLING & FREITAG GMBH © 2018 Version 1.4 Page 16 of 42
The following steps require the use of a transport cover including a K&F SPECTRA 212 rigging
aid set for each speaker. The hinges are required for a single person to set up the speaker
array; otherwise, the process must be performed by at least two people.
1)
