RL944K RL944K1

Studio Reference Monitor Loudspeaker RL944K RL944K1 with cardioid radiation characteristic in bass range.

The Studio Monitor Speaker RL 944K is an active three-way monitor with cardioids characteristic within the frequency range from 35 Hz through 300 Hz. It can universally be applied as the main monitoring speaker for sound and video studios. By this radiating characteristic the reflections on the back walls of listening rooms can be minimized. The loudspeaker RL 944K1 is another variant of the RL 944K. RL 944K1 contains a stand-alone amplifier and is of smaller height of the box so that it is superior suited for the insertion in video walls and outside-broadcasting vans.
The unit for the medium and high-frequency range is combined in a coaxial manner with a long-throw bass system and is provided with a directivity index, which supplements in an excellent way that of the bass system. The directional characteristics have been optimized with regard to small basis widths and short listening distances. Hereby they are outstanding qualified for the use in outside broadcasting vans. The high-power long-throw bass system is driven in a compact cabinet so that optimum impulse behaviour can be reached. Moreover, with a series of constructional measures we have provided that convincing lowest values of non-linear distortions and colorations could be reached. The whole system is superior by excellent localization behaviour.The three-channel MOSFET power amplifier with electronic crossover is integrated within the back wall of the cabinet and can be swing out 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 transfer characteristic can be matched to the acoustical conditions of the reproduction room as well as to the set-up situation by a low-frequent infinitely variable adaptation within two adjustable frequency ranges.
Various special stands and holding devices can be delivered as accessories. Appropriate fixing elements are integrated in the loudspeaker cabinet. Optionally, the loudspeaker can magnetically be compensated with regard to its scattering field.
