– The K-array KS5 is a self-powered subwoofer. It is best suited for high-power extended bass response applications in arenas, theatres, stadiums, concert halls, houses of worship and outdoor events.
– The 21” loudspeakers feature neodymium magnets with 6” voice coils driven by powerful Class D amplifiers. The large ports are designed to be fully symmetrical to the speakers, which means the back loading on the drivers is consistent and even with no port air turbulence. The triangle port construction also provides excellent structural integrity and strength, effectively eliminating any box resonance.
– The rear panel provides inputs for a balanced line signal, a balanced microphone signal with phantom power, and digital signals in AES/EBU protocol. An integrated touch screen provides intuitive managing and editing of powerful DSP controlling: Input and output levels, internally generated test signal, In/Out routing, Speakon output delay (up to 12 ms), subwoofer delay (up to 12 ms), overall system delay (up to 330 ms).
– All DSP functions, including EQ can be controlled with remote managing software via USB or RS485, again conveniently on a standard XLR. There are different DSP presets, specifically made by K-array to optimize the system performance of the variety of device configuration available. In addition the user can also create, save, and store his/her own personal presets on the KS5 module.
– All KS5 components are designed by the K-array R&D department and custom-made under the K-array quality control system.
