User's Manual
2.
The K&F SPECTRA 212 is a compact 3-way speaker with equalization in two ways. Separate K&F power
amplifiers are required for driving the speaker. he K&F SPECTRA 212 features a detachable midrange/
tweeter unit that can be rotated by 90°. This allows for using it as a point source or – as part of an array
– as a line source. The midrange/tweeter unit is mounted inside the enclosure using 14 grille-screws and
two extra locking screws. To rotate the unit by 90° in order to change between point source and line
source operation, first remove the 14 grille screws, the grille, and the locking screws, then align the unit
as desired and replace all screws and the grille. In addition, use the switch at the rear panel to change
between point source and line source operation.
With regard to its weight of 48 kg, two people are required for handling the K&F SPECTRA 212.
In point-source operation, the H/V beam width is 60° × +5/–25°. This allows for using a K&F
SPECTRA 212 as a single high-performance top. The asymmetric vertical beamwidth simplifies orientation
towards the audience and at the same time reduces unwanted ceiling reflections. In line source operation,
the H/V beamwidth is 30° × 60°.
The connection system and the optionally available K&F rigging system allow for creating and suspending
either a horizontal line of up to six K&F SPECTRA 212 or a vertical array of up to four K&F SPECTRA 212.
