The sound system further comprises a control unit configured for individually selecting, for each of at least two playback zones, a mixing mode depending on the type of the second audio signal, wherein the mixing modes relate to a relation between signal output gains of the first and second audio signals.

Abstract: The invention relates to a filter unit for a switchgear cabinet, comprising a filter housing having an air passage that can be covered by an air passage grating at least to some extent. To allow such a filter unit to be maintenanced easily, it provided according to the invention that the air passage grating is hinged indirectly or directly to the filter housing and can be adjusted between a closed position and an opened maintenance position. The filter housing has a retainer which positively blocks a catch of the air passage grating in the maintenance position.

Abstract: A device for beam shaping includes a heat dissipation body having an upper side with a planar section and a plurality of laser elements next to one another on the planar section of the upper side that respectively emit a ray bundle having a fast-axis divergence and, perpendicular thereto, a slow-axis divergence. A reflection element is arranged such that the ray bundles of the individual laser elements extend parallel to one another and at an elevation angle of greater than 0° and less than 90° with respect to the planar section after exactly one reflection at the associated reflection element. The reflected ray bundles are stacked in the optical path downstream of the reflection elements in a first plane perpendicular to the beam direction and a connecting line, lying in the first plane, of the centers of the reflected ray bundles extends perpendicular to the direction of the slow axis.

Abstract: The invention relates to a combination cable and air channel for air conditioning an electrical enclosure, comprising an air channel and a cable channel which adjoins the air channel and which is led parallel to the air channel. A first longitudinal face of the air channel has at least one opening, and a longitudinal face of the cable channel manner. The invention further relates to a corresponding electrical enclosure.

Abstract: A filter apparatus, a method for the manufacture of the filter apparatus, the use of the filter apparatus in medical, chemical and/or biotechnological applications, and an apparatus for use in the manufacture of the filter apparatus. The filter apparatus has a cylindrical housing and a plurality of hollow fibers. The hollow fibers are combined to form a bundle in the housing and are embedded and held in each case at the end sides in a molding compound. The filtrate space is filled with particles of a chemically or physically active substance.
