3 Product Description
3.1 Cluster plates (point-source mode)
Cluster plates are used for clustering two SPECTRA 212i systems in point-source mode. This
allows for achieving a larger overall directivity. The accessories allow interconnecting the
speakers in acoustically logical angles.
We recommend using the cluster plates for the SPECTRA 212i N speaker version only.
Two SPECTRA 212i N speakers configured with cluster plates provide an overall directivity of
100° × 30°.
Two product variants are available for point-source applications:
3.1.1 Cluster Plate Set
Allows for setting up a cluster of SPECTRA 212i speakers in point-source mode at a predefined
angle.
3.1.2 Horizontal Cluster Flying Set
You can place clusters interconnect-
ed using cluster plates on the floor or
a base. For this approach, you just
need to interconnect the speaker
tops using a plate. A cluster plate set
allows for building two clusters with
two speakers each.
Allows for suspending a cluster with
two vertically arranged speakers in
point-source mode.
This setup allows for achieving vari-
ous tilt angles.
Using the horizontal cluster flying
set, you can suspend two intercon-
nected speakers using the flybar (in-
cluded with the set).
Using the appropriate flybar hole,
you can adjust the desired speaker
down-tilt as required.
Repositioning the flybar shifts the
grid by half the dimension, thus ef-
fectively doubling the achievable
down-tilt options.
Suspend the speakers using either
K&F 450 rotation clamps or suitable
shackles (3.25 t).

3.2 Connector (Line-Source Mode)
Connectors allow for connecting two speakers to build an array for operation in line-source
mode. Interconnecting the speakers using the connectors allows for achieving the acoustically
logical angle between the speakers for line-source operation.
You can use the connectors for interconnecting the following speaker combinations:
•2 x SPECTRA 212i N (directivity: 60° × 30° )
•2 x SPECTRA 212i XW (directivity: 120° × 30°)
•1 x SPECTRA 212i N and 1 × SPECTRA 212i XW
Two product variants are available for line-source applications:
3.2.1 Connector Set
Allows for setting up an array of SPECTRA 212i speakers in line-source mode.
Floor operation:
You can place arrays interconnected
using connectors on the floor or a
base. For this approach, you just
need to interconnect the speaker
tops using a plate. A connector set
allows for building two arrays with
two speakers each.
Suspended operation:
A connector set allows for building a
vertical array of two speakers. To sus-
pend this setup, you will also need a
K&F SPECTRA 212i flying frame.

3.2.2 Connector Flying Set
Allows for suspending a horizontal
array of two SPECTRA 212i speakers
in line-source mode.
This setup allows for achieving vari-
ous tilt angles.
Using the connector flying set, you
can suspend two interconnected
speakers using the flybar (included
with the set). The speakers are inter-
connected through the connectors.
Using the appropriate flybar hole,
you can adjust the desired speaker
down-tilt as required. Repositioning
the flybar shifts the grid by half the
dimension, thus effectively doubling
the achievable down-tilt options.
Suspend the speakers using either
K&F 450 rotation clamps or suitable
shackles (3.25 t).
