A professional column solution designed to evolve with your events

The HK Audio ELEMENTS MK2 is an active, modular column PA system designed for rental companies, technicians, DJs and event organisers looking for elegant, powerful and particularly discreet sound reinforcement. This new generation retains the DNA of the ELEMENTS series while adding a more robust design, more comprehensive DSP management and even greater modularity.

The range is built around the ELEMENTS MK2 635 mid/high module, the ELEMENTS MK2 SPACER, and two active subwoofers designed for different applications: the compact 10-inch 110 Sub A for speech, corporate events and background music, and the 15-inch 115 Sub A for demanding musical performances, DJ sets and concerts. The configuration can accommodate up to three mid/high modules and two subwoofers to increase coverage and impact in large venues.

For DJs, bands, rental companies and events where aesthetics matter as much as sound

Thanks to its slim column format and installation without visible cables between the elements, the HK Audio ELEMENTS MK2 system fits naturally into weddings, cocktail parties, conferences, places of worship, theatres, multipurpose venues and corporate events. Its understated aesthetic allows for discreet integration into premium settings without sacrificing sonic presence.

Mobile DJs and entertainers will appreciate its fast deployment, the headroom provided by the 115 Sub A subwoofer and the option to add modules or low-end extension depending on the size of the dance floor. For speeches, presentations and meetings, the 110 Sub A delivers solid low-midrange reproduction and natural voice clarity. Live bands, acoustic ensembles and event performers benefit from even projection, with intelligibility maintained right to the back of the venue.

The system is also suitable for rental companies that need reliable equipment that is quick to install and easy to scale. Automatic detection of the mid/high modules eliminates complex adjustments and ensures a consistent response, whatever configuration is selected.

Controlled line array coverage, intelligent DSP and ultra-fast SnapLock setup

ELEMENTS MK2 uses a modular line array column design. The ELEMENTS MK2 635 module houses six 3.25-inch speakers combined with six phase plug-type waveguides. This architecture provides 90-degree horizontal dispersion and controlled 5-degree vertical dispersion. The result is more even audience cover, with less variation in volume between the front rows and the back of the venue.

The HK Audio SnapLock locking system securely connects the subwoofer, spacer and columns with one hand and without tools. Integrated signal contacts replace exposed connections, reduce clutter and improve reliability during intensive use. This design provides a real time saving for frequent setup and teardown.

The active subwoofers feature a DSP platform with a 10-band parametric equaliser, high-pass and low-pass filters, polarity adjustment, limiter, mute and delay on the DSP output. The Flat, Contour, Voice and Remote presets allow the sound to be quickly adapted for music playback, speech or a customised setup. The system is controlled via the DSP Control software.

Network connectivity via Ethercon RJ45 enables remote control as well as digital Milan-AVB audio transmission over a single network cable. The DSP XLR output can also process and send a signal to additional speakers, monitors, frontfills, delay lines or additional subwoofers. ELEMENTS MK2 can also be integrated into installations incorporating HK Audio LINEAR 5 MK2 and LINEAR 9 models.
