HK Audio LINEAR 5 MK II 115 XA

The LINEAR 5 MK II series not only gives professional performers and rental companies a reliable high-performance everyday tool – this state-of-the-art series, which has been redesigned from the ground up, features remote-controlled DSPs, more power and cardioid-capable subwoofers. With the sturdy wooden enclosures, large selection of standard elements and extensive range of accessories, LINEAR 5 MK II is a powerful and innovative drive for all those who want to impress their audiences day after day. First-class sound and high performance made in Germany.

Established technology made better

The LINEAR 5 MK II series is the next logical step in the development of the popular LINEAR 5 series. With more power and weighing in at up to 3 kg lighter, featuring more compact dimensions and the added benefit of digital optimisation via the DSP CONTROL software, it takes day-to-day tasks to a whole new level. New series elements, such as the series’ own subwoofers and the LINEAR 5 MK II 110 XA and 115 XA full-range mid/high units, expand the already very extensive range of applications.

Rotatable horns with optimal dispersion angles for each mid/high unit make them ideal solutions for cluster setups or as stage monitors. Sturdy wooden enclosures ensure durability and investment protection. The wide range of accessories for transportation and weather protection, rigging and assembly make LINEAR 5 MK II a reliable workhorse.

The compact, horn-loaded LINEAR 5 MK II 308 LTA long-throw mid/high unit offers enormous sound depth, high flexibility and compatibility thanks to the DSP with FIR filter and DSP-Out.

DSP – Powerful and smart

The integrated high-performance DSPs allow tuning of the system with high precision. They provide increased usable sound pressure before distortion sets in and reduce the risk of feedback significantly.

Not only can the four matching presets be accessed directly at the loudspeaker cabinet, but also via Ethernet connection and the DSP CONTROL software for larger system set-ups on a Mac or PC and ad-hoc adjustements.

The DSP Out also allows integration of a non-networked loudspeaker, processing its signal independently of the DSP settings within the loudspeaker using the DSP CONTROL software.

HK Audio Multicell Transformer (MCT)
High coverage and more usable sound pressure

Developed by HK Audio, the LINEAR 5 MK II 308 LTA’s Multicell Transformer (MCT) is made up of many small horns of different sizes and lengths. Interfering horn resonances are pushed above the transmission range, which minimises THD and reduces distortion.

As a result, there is significantly more usable sound pressure available. At the same time, the MCT technology enables analogue beam steering and thus an asymmetrical horn dispersion pattern.

This, combined with the very precise dispersion, makes headstack and cluster arrangements very easy to achieve. This allows the MCT to reach long ranges even with compact dimensions. Balanced and powerful sound can reach up to 40 metres and up to 3000 people without having to use delay lines.

Cardioid – Problem solver for professionals in any situation

Professional sound technicians respond to stringent sound insulation requirements, uncontrolled bass dispersion on and behind the stage and a high feedback risk in the lower frequency range with Cardioid technology for the subwoofers. This technical trick is now easily achieved without measurement technology: simply set up, select a preset, and you’re done!

The Cardioid setup attenuates the bass sound pressure of the physically spherically radiating subwoofers behind the subwoofers by up to 34 dB. There is a slight increase in sound pressure of approx. 2 dB in the front sound dispersion. This results in a directional, cardioid radiation pattern.

Cardioid sound reinforcement technology can be used with the LINEAR 5 MK II 115 Sub A and 118 Sub A with vertically stacked subwoofers and also with horizontal setups. This is a huge advantage on low stages. For larger vertical cardioid stacks with up to three subwoofers, the powerful LINEAR 5 MK II 118 Sub HPA offers 1:1 and 2:1 cardioid presets

Robust housings
Optimized for all application scenarios

The acoustic properties and stability of wood cannot be achieved with any other material in loudspeaker construction. That is why nearly all LINEAR 5 MK II components are built into wooden cabinets made of MDF and birch multiplex. The LINEAR 5 MK II 118 Sub A and the LINEAR 5 MK II 118 Sub HPA are completely made of birch multiplex. Despite the robust material, LINEAR 5 MK II is extremely compact and comparatively light.  MultiGrip handles ensure easy handling and, together with the optional tilt brackets, provide a secure hold in flight for the mid/high units.

For use as compact, powerful and low-feedback stage monitors, the housings of the LINEAR 5 MK II XA mid/high units are equipped with a 31° monitor slope and offer a safe and firm stand even when lying crosswise. The rotatable horns allow the dispersion angles to be optimally adjusted to the desired setup. The enclosures of the LINEAR 5 MK II FA full-range mid/high units provide more pressure and volume in the bass range.

Smaller, lighter, louder

LINEAR 5 MK II is smaller, lighter and louder than the LINEAR 5 series. With up to 3 kg less weight at the same sound pressure level, the LINEAR 5 MK II 112 XA is the loudest and lightest mid/high unit in its speaker class. LINEAR 5 MK II 308 LTA and HK Audio 118 Sub HPA work together to deliver long throws and powerful bass in compact dimensions.

New models

Flexible and broadly positioned – that’s what you expect from a good rental company, and that’s exactly what LINEAR 5 MK II offers. Mid/high units in all reasonable sizes and standard subwoofers cover all conceivable application scenarios in this speaker class optimally and reliably.

The popular LINEAR 5 series has been completely revised, adapted from the ground up to meet the current requirements of modern sound reinforcement systems and expanded to include the following models:

• LINEAR 5 MK II 110 XA – ultra-compact and powerful multifunctional mid/high unit
• LINEAR 5 MK II 115 XA – volume, pressure and high sound pressure level as monitor or mid/high unit
• LINEAR 5 MK II 115 SUB A – compact and crisp “easy handling” subwoofer
• LINEAR 5 MK II 118 SUB A – uncompromising power and pressure down to the deepest bass cellar
• LINEAR 5 MK II 118 Sub HPA – compact, with the most powerful power amplifier in the series and very precise and powerful bass reproduction.

Accessories – equipped for all situations

The optional accessories of the LINEAR 5 MK II series expand the application possibilities enormously and provide customized, high-quality and secure solutions.

Weather Protective Cover – The sound never stops, come rain, come sunshine

The Weather Protective Covers for all LINEAR 5 MK II mid/high units (except LINEAR 5 MK II 308 LTA and 118 Sub HPA) and subwoofers are precisely manufactured and equipped with many practical details. They are an optimal protection against moisture and wetness, at the same time a robust transport protection. Waterproof acoustic gauze protects the front of the speakers and drivers without affecting the sound. Depending on the model, the front flap can be easily and securely clipped to the side of the speaker or rolled up at the head end without interfering with stacking, clustering or cardioid setups.

On the backs, sturdy transparent viewing windows keep water out of electronics and provide access to controls and a cable entry. Handles remain usable with closable engagements or cut-aways. For the 115 XA, 112 FA and 115 FA mid/high units, this allows the rigging brackets to be installed even when the rain cover is on.  The subwoofer covers provide lockable access to the thread for the spacer rods.

Tilt brackets – perfect alignment and easy handling for rigging operations.

TB-45N and TB-45NQ are tilt brackets made of high-strength steel for mounting speaker cabinets on truss spars, ceilings, wall brackets, beams and on tripods. The TB-45NQ are equipped with quick release pins for fast mounting. Both brackets have a maximum load capacity of 70 kg according to WLL and 35 kg according to DGUV-V 17. Simple and flexible vertical and horizontal alignment is possible.

RCS Rain Cover Set

The RCS Rain Cover Set supplied with the LINEAR 5 MK II 308 LTA and 118 Sub HPA reliably protects the electronics from rain, leaving all connections accessible and ensuring the controls are easy to read.

Accessories for cluster and headstack setups

The Headstack Extension Set is the extension of the TB-45N or TB-45NQ to accommodate a LINEAR 5 MK II 308 LTA headstack at the correct centre of gravity and tilt point. The TB-HES extends the sides of the TB-45 and connects to the headstack at the free screw points of the sliding plates of the LINEAR 5 MK II 308 LTA speakers.

The Pick Point (PP) and the Cluster Plate (CP) provide either two or three attachment points for rigging and angling the LINEAR 5 MK II 308 LTA. The following configurations can be built and rigged with just one set of the PP-CP. 2 x single use, 2 x headstack, 2 x cluster or 2 x headstack cluster. The PP-CP set is therefore a highly universal accessory and offers an unbeatable price/performance ratio

The DFP double flange plate is required when a cluster is to be stacked on a LINEAR 5 MK II 118 Sub HPA with mounting poles. This allows the cluster to be easily adjusted to the desired height with the mounting poles and aligned accordingly. The correct angle of the horizontal cluster is achieved by screwing the back of the 308 LTA onto the mounting poles or Tilt-Units.
