K&F SPECTRA 212
2 Product Description
The SPECTRA 212 is a compact 3-way, convertible line array speaker with equalization in two
ways. Separate K&F power amplifiers are required for driving the SPECTRA 212.
The connection system and the optionally available K&F rigging system allow for creating and
suspending either a horizontal line of up to six SPECTRA 212 or a vertical array of up to four
SPECTRA 212.
The speaker is available in two versions:
•XW (extra wide) with 120° × 30° directivity
•N (narrow) with 60° × 30° directivity
These versions can be used both in a line array (in line-source mode) or as a point source (in
point-source mode). To change the operating mode, you need to rotate the internal mid-
range/tweeter unit.
Various point-source modes are available:
•Point source with a VariQ midrange/tweeter unit down-tilt by –10°
Asymmetrical vertical directivity (30°× +5 °…–25 °)
In point-source mode with down-tilt, the asymmetrical vertical directivity simplifies orien-
tation towards the audience while reducing unwanted ceiling reflections.
•Point source with a VariQ midrange/tweeter unit up-tilt by 10°
Asymmetrical vertical directivity (30°× +25 °…–5 °)
In point-source mode with up-tilt, the asymmetrical vertical directivity simplifies orientation
towards the audience if they are positioned above the speaker.
2.1 Intended Use
Be sure to use the K&F SPECTRA 212 only with system amplifiers or controllers approved by
KLING & FREITAG.
The product and any optional accessories are suitable for indoor use (exhibition halls, event
halls, etc.). This product is not designed for prolonged use in corrosive environments. Outdoor
operation is permitted, provided that the speaker is protected against direct weather impact.
For outdoor installation, you will need to manufacture appropriate custom fastening equip-
ment with regard to the place and purpose of use. Be sure to take outdoor effects (wind, snow
loads, etc.) into account. The use of standard accessories for temporary or permanent outdoor
installation is not permitted.
When using the optional K&F SPECTRA 212 subwoofer adapter, you can use K&F subwoofers
as a pedestal provided the required stability is ensured. Refer to the manual for K&F SPECTRA
212 accessories for more information. The connection system and the optionally available K&F
rigging system allow for creating and suspending either a horizontal line of up to six SPECTRA
212 or a vertical array of up to four SPECTRA 212. In outdoor use, if the product is suspended
using the optional K&F rigging system, be sure to guy it and to end operation at wind forces
of 8 bft or more. People may safely stand below the structure during operation.
Installation and operation must be performed by qualified event technicians or appropriately
trained persons. Planning must be performed and responsibility be taken by qualified person-
nel only.
Any other use not described in this document is not an intended use.

6 Safety Instructions
6.1 Notes on Upright Operation
6.2 Preventing Hearing Damage
WARNING
Installation and operation must be performed by qualified event technicians or appropriately
trained persons. Planning must be performed and responsibility be taken by qualified person-
nel only.
K&F SPECTRA 212 speakers are to be flown by qualified personnel (riggers) only! For instruc-
tions for flying speakers, handling arrays, pickpoint tables, and other information, refer to the
relevant accessory manuals. The manuals are available for free download on our website at
www.kling-freitag.de.
With regard to its weight of 48 kg, two people are required for handling the K&F
SPECTRA 212.
For safety instructions on the various installation options, refer to the respective manuals.
WARNING
If you use your speakers in an upright position, ensure sufficient stability. To avoid injury or
damage, always be sure to mount the speakers securely so that they do not fall.
Note that the speakers can move as a result of vibrations. To prevent them from falling from
their mounted position, they must be secured properly.
Mounted speaker(s) must not tilt even at an inclination angle of 15°. If necessary, use extra
fastenings.
Be sure to follow the relevant national specifications, norms, and safety regulations.
When laying the connecting cables, make sure that nobody can trip.
CAUTION
Keep your distance from operating speakers. This equipment is capable of delivering sound
pressure levels in excess of 90dB SPL, which may cause permanent hearing damage.
Be sure to comply with your local noise regulations.
If possible, install the speakers in a place where nobody can stand right in front of them. If nec-
essary, limit the maximum volume level.
