3 System description
The RL 922K has been designed for both the professional user at medium-size to large audio, video
and film studios and for the discerning music enthusiast.
By the cardioid radiation characteristics within the frequency range from 30 Hz through 250 Hz
the reflections on the back walls of listening rooms can be minimized. In addition the transfer
characteristic can be matched to the acoustical conditions of the reproduction room as well as to the
set-up situation by an integrated room matching filter.
The total directivity index of the monitor was optimized for middle through larger listening distances
between two and three metres. As the bass system a very linear 300 mm (12″) long-throw driver in a
cardioid cabinet is employed, delivering excellent impulse fidelity. The 125 mm (5″) cone is mounted
together with the 25 mm (1″) dome tweeter coaxially in front of the bass system allowing a precise
steering of the focal perspective. As a result a realistic and steady spatial performance of the sound
pattern around the listening position is achieved, with high homogeneity and smallest possible
coloration. By the great membrane area the RL 922K is in the highest degree level proof while at
the same time it has the lowest distortions. Therefore the RL 922K is a precision studio tool allowing
fatigue free working for hours.
The three-channel MOSFET power amplifier with electronic crossover is integrated into the back
of the cabinet and is hinged for service purposes. An intermittent LED lighting signals when the
overload limit is reached. After crossing of the maximum level the output level will be reduced by
20 dB to avoid any overloading of the components.
The RL 922K1 is a more compact cabinet variant of the RL 922K, that is employed when not enough
room is available. Be it a video wall or an outside broadcasting van. As an alternative to the standardly
provided MOSFET amplifier in an upright standing enclosure the 19-inch compatible Class-D amplifier
RL-Amplifier is also available.
A variety of special stands and racks is available as accessories. According fixing elements have been
integrated into the loudspeaker cabinet.
