ME 901K

The Studio Monitor Speaker ME 901K is an active three-way monitor with cardioids characteristic within the frequency range from 30 Hz through 250 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 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. 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 total directivity index of the monitor was optimized for larger listening distances. The whole system is superior by excellent localization behaviour. 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 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. Various special stands and holding devices can be delivered as accessories.

Important information about deviations from sample pattern

Wood is a natural product. Even the most thorough manufacturing can result in deviations in colour or structure and is no cause for complaint.
