The loudspeaker of the type MO-2 is a compact studio monitor of our MO series. It is qualified for the use in near-field and middle-field applications as well as in outside broadcasting vans. With multichannel application we recommend the supplement by one of our active bass loudspeakers, BASIS 11…14K. Because of the construction in an active coaxial two-way technology we can ensure sound colour compatibility to our studio control monitor loudspeakers. Moreover, by that constructive measure we can achieve high naturalness and homogeneity of the irradiated sound event. Also with regard to the localisation definition and the feasibly minimum imaging of phantom sound sources the MO-2 is seamless matched to all the loudspeakers of the RL and MO series. The directivity index was determined in such a manner that an operation is feasible up to 1m minimum basis width.

The loudspeaker unit is supplied with a 160 mm cone low-frequency driver and a 25 mm high-frequency dome driver arranged coaxially. They are powered by separate MOSFET power amplifiers with an active crossover and electronic protection circuit in the back part of the cabinet. The MO-2 contains symmetric XLR input with calibrated input level adjustment. According to the position of the monitor box the amplitude/ frequency curve can be well matched in the low- and in the high-frequency range as well as in the region about 300 Hz by means of the controls on the back side.

The status of operation and also the status when the maximum level is overridden will be signalized by a two-coloured LED. The loudspeaker is magnetically shielded for compensating stray fields.

The design of the box is finished in MDF with true veneer. Various special stands and holds are available as optional extras. The corresponding appliances are integrated in the case.

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.
Images are represented differently on every screen and hence not colour-proof.
