Xperience IV is an extraordinary active PA system with integral digital amplifiers and digital signal processors from the latest generation and is compact, lightweight and easy to operate. Xperience IV can be used in a wide range of applications and can be extended or combined in a multitude of different ways. Xperience IV was developed for sound companies, musicians and professional Djs who require a powerful Plug & Play system that is capable of achieving perfect sound reproduction for events at venues ranging from hotels to concert halls. Thanks to state-of-the-art digital technology (Fohhn Audio DSPs), Xperience IV comprises a large number of audio devices that would otherwise have to be transported in external racks. At the same time, Xperience IV is much lighter, occupies less loading space and can be set up in no time at all. The system also minimises the amount of cables and therefore reduces the number of possible sources of error. The integral audio devices allow you to adapt the Xperience to continually changing sound requirements. You can connect small, medium or large mid-high speakers to the active bass, depending on the area size and visual requirements. Perfectly adapted performance presets that can be activated at the press of a button are available for every speaker type. You can also adjust the system sound to suit your own requirements or adapt it to the room acoustics. Preprogrammed or configurable sound presets will provide you with assistance here. Several Xperience systems can be connected in series and controlled centrally from one location. The Xperience IV can generally be operated in 2 ways: via the clearly laid out blue 4-line display or via a laptop using the remote control. Xperience IV makes sound reproduction easier and more versatile than ever.

>The self-powered subwoofer XS-4 – it is the lightest in it's class.<
Extremely powerful 18“ subwoofer, state-of-the-art Neodym technology, extremely lightweight as a result and at only 39kg, as lightweight as a conventional 15“ subwoofer. Integral 1500W CLASS D digital amplifier and Fohhn Audio DSPs. The active Sub can be combined with all Fohhn Top speakers.A corresponding preset is available for each Top. Access to the Fohhn Audio DSP functions such as presets, equalisers etc. via a user-friendly 4-line display direct on the active Sub or via a remote control/laptop. Software is included. Transport cover with wheels is also available to protect the electronics system. Recessed transport handles allow for extremely good handling. Outstanding manufacturing quality „Made in Germany“.

>Equipment features of XS-4<

• 18“ long excursion speaker

• Digital class D stereo amplifier (1500W) and 2 integral DSPs

• 2 ergonomic, deep-set handles

• wheel board (electrical system protected during transport)

• 20 mm flange for spacer

• Sliding feeds on base and side

• Resistant black paintwork

>Fohhn® Mains Control – the integrated mains supply monitoring system<
During use, the supply to the amplifier is constantly monitored. If at any time it exceeds the maximum permitted range (180-255 VAC), the supply will be interrupted. During power up it also minimizes the input surge current by switching on at the mains voltage zero crossing.

>Top speakers: all models of Fohhn Top can be used in combination with the self-powered sub XS-4<
i.e. Xperience Top speakers such as the XT-1, XT-2 or XT-3ND. This also includes the new XT-33 (12“/1“CD, 500W), XT-4 (12“/1,4“CD, 500W) and the XT-5 (15“/1,4“ CD, 600W) Tops. Even speakers from the RoadLine and Perform series and EasySat series can be used in combination with the active XS-4 without a second thought. A perfectly adapted preset is available for each speaker type. This preset can be activated quickly and easily at the press of a button. The speaker is protected by complex 3-band processing for bass/mid and high frequencies.

>More lightweight and powerful thanks to state-of-the-art Neodym technology.<
The XS-4 active bass and the new XT-33, XT-4 and XT-5 Top speakers are fully equipped with the latest Neodym speakers and are therefore extremely lightweight. The most impressive aspect of the speakers is that all housings are manufactured from highquality multiplex beech wood and not plastic. The clear reduction in weight compared to conventional systems results from the use of state-of-the-art digital technology and Neodym speakers.Users also benefit from a reduction in weight and transport space because they no longer need to transport extra equipment and racks to venues. External amplifiers, controllers, crossovers, equalisers and similar equipment are no longer required.

>Practical system combinations<
Basic version: 1 x XS-4 active sub and 2 x XT-33 (12“/1“CD) Neodym speakers. Ideal for sound reproduction for bands, DJs, entertainers and at shows and galas. Fits easily in passenger cars and offers high power reserves. Plug & Play. Power version: 2 x XS-4 active subs in bridge mode and 2 x XT-4 (12“/1.4“CD) or XT-5 (15“/1.4“ CD, 600W). The XT-5 is fitted with extremely powerful Neodym components. The 3.5“ high-frequency driver has considerable power reserves and produces an impressive, refined sound in combination with the specially developed 1.4“ aluminium CD horn. The powerful sound the system produces makes it extremely suitable for shows and parties. System output: 3000W. Larger systems: The system can be extended to include any number of active subwoofers with a corresponding number of Top speakers and of course can be combined with large horn-loaded systems from the Perform series.

>Easy to operate<
A control panel with a blue, four-line LCD display is integrated in the active Sub so that users can adjust and view the DSP functions.
The system´s network compatibility and remote control options via a laptop provide you with assistance while you work. For connecting the active Sub to a PC the Fohhn-Net Adaptor NA-1 is necessary.
