Advanced DSP technology – Multiband limiter with filter presets

The advanced DSP technology driving LINEAR 3 has one main purpose: to make the job of musicians and DJs easier! LINEAR 3 gives you the ultimate sound in any situation. And it’s so simple to use!

An intelligent multiband limiter and filtering of the frequency response in the ‘Contour’ setting ensure a consistently sweet and assertive sound, from super quiet to really loud.

The multiband limiter monitors and controls the relevant frequency bands separately, only intervening when it is needed. HK Audio’s engineers have developed, tested and fine-tuned all the components and options offered by LINEAR 3 for all the relevant applications, working with musicians to optimise them for practical use.

As a result, LINEAR 3 guarantees an impressively effective sound experience, even for semi-professional musicians and DJs who are not dedicated PA specialists.

This gives musicians on stage more room for musical creativity and a top performance.

HK Audio MultiGrip

The built-in HK Audio MultiGrips make handling the speakers a breeze and ensure even more safety in every situation. They also allow for professional flying hardware to be fitted. The TB-45N or TB-45NQ tilt brackets can be mounted directly to the MultiGrips on the LINEAR 3 112 FA and LINEAR 3 115 FA models, making them ideal for professional rigging or installation. The models of the LINEAR 3 series have 4 x M8 mounting points and can be flown by mounting AP-8 attachment points, for example.
